Basis of Preparation [Abstract] | |
Basis of Preparation | 2. Basis of Preparation The consolidated financial statements of Korea Electric Power Corporation and subsidiaries (the “Company”) were authorized for issuance by the Board of Directors on February 23, 2018. (1) Statement of compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). (2) Basis of measurement These consolidated financial statements have been prepared on the historical cost basis, except for the following material items in the consolidated statements of financial position: • derivative financial instruments are measured at fair value • available-for-sale • liabilities for defined benefit plans are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets (3) Functional and presentation currency These consolidated financial statements are presented in Korean won (“Won”), which is KEPCO’s functional and presentation currency. (4) Use of estimates and judgments The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year. (i) Unbilled revenue Energy delivered but not metered nor billed are calculated at the reporting date and is estimated based on consumption statistics and selling price estimates. Determination of the unbilled revenues at the end of the reporting period is sensitive to the estimated consumptions and prices based on statistics. Unbilled revenue recognized for the years ended December 31, 2016 and 2017 are ₩1,615,322 million and ₩1,672,385 million, respectively. (ii) Continuing operation of Wolsong Unit 1 nuclear power plant Wolsong Unit 1 nuclear power plant of the Company commenced operations on November 21, 1982 and its 30-year According to the Eighth Basic Plan for Electricity Supply and Demand by the Ministry of Trade, Industry and Energy, Wolsong Unit 1 nuclear power plant is expected to go through a comprehensive evaluation for the feasibility of continuous operation including economic efficiency and acceptability of household and community in 2018. The Korean government plans to refund to the Company for reasonable expenditures incurred in relation to the phase-out Information about critical judgments in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes: • Note 17 – Investments in Associates and Joint Ventures • Note 18 – Property, Plant and Equipment • Note 20 – Construction Services Contracts • Note 45 – Risk Management Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year is included in the following notes: • Note 41 – Income Taxes • Note 25 – Employment Benefits (5) Changes in accounting policies (i) Amendments to IAS 7 ‘Statement of Cash Flows’ The Company has adopted amendments to IAS ‘Statement of Cash Flows’ since January 1, 2017. The amendments require changes in liabilities arising from financing activities to be disclosed. The amendments are not required to provide comparative information for prior periods when applying for the first time. Information about changes in liabilities arising from financing activities is included in note 23 and note 24. (ii) Amendments to IAS 12 ‘Income Taxes’ The Company has adopted amendments to IAS 12 ‘Income Taxes’ since January 2017. The amendments clarify that unrealized losses on fixed-rate debt instruments measured at fair value and measured at cost for tax purposes give rise to a deductible temporary difference regardless of whether the holder expects to recover the carrying amount of the debt instrument by sale or by use and that the estimate of probable future taxable profit may include the recovery of some of assets for more than their carrying amount. When the Company assesses whether there will be sufficient taxable profit, the Company should compare the deductible temporary differences with future taxable profit that excludes tax deductions resulting from the reversal of those deductible temporary differences. The Company believes that there is no significant impact on the Company’s consolidated financial statements and did not retroactively restate the comparative consolidated financial statements for the prior period. (6) New standards and amendments not yet adopted The following new standards, including IFRS 9 ‘Financial Instruments’ and IFRS 15 ‘Revenue from Contracts with Customers’, interpretations and amendments to existing standards have been published but are not mandatory for the Company for annual periods beginning on January 1, 2017, and the Company has not early adopted them. The Company will apply IFRS 9 ‘Financial Instruments’ and IFRS 15 ‘Revenue from Contracts with Customers’ for annual periods beginning on January 1, 2018. The Company has conducted a detailed assessment on adoption of these standards and based on the circumstance and information available when these financial statements were authorized for issuance. (i) IFRS 9 ‘Financial Instruments’ IFRS 9 sets out the requirements for recognizing and measuring financial assets, financial liabilities and certain contracts to buy or sell non-financial The Company will apply the exemption allowing it not to restate the comparative information for prior periods upon adoption of IFRS 9. The Company will retroactively apply the cumulative effect of the adoption of IFRS 9 in retained earnings as of the date of initial application (January 1, 2018). Expected impacts on the consolidated financial statements are categorized as follows: ① Classification and measurement of financial assets IFRS 9 includes a new classification and measurement of financial assets that reflects the business model in which assets are managed and their cash flow characteristics. Under IFRS 9, financial assets are classified into three principal categories; measured at amortized cost, fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVTPL) based on the business model in which assets are managed and their cash flow characteristics. Under IFRS 9, derivatives embedded in hybrid contracts where the host is a financial asset are not bifurcated. Instead, the hybrid financial instrument as a whole is assessed for classification. The criteria for classification and measurement of financial assets under IFRS 9 are as follows: • A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: 1) the asset is held within a business model whose objective is to hold assets to collect contractual cash flows; and 2) the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. • A financial asset is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL: 1) the asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and 2) the contractual terms of the financial asset give rise on specified dates to cash flow that are solely payments of principal and interest on the principal amount outstanding. On initial recognition of equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in fair value in OCI, and will not reclassify(recycle) the those items in OCI to profit or loss subsequently. • A financial asset is measured at FVTPL if the contractual terms of the financial asset give rise to specified dates to cash flows that are not solely payments of principal and interest on the principal amount outstanding, the debt instrument is held within a business model whose objective is to sell the asset, or the equity instruments that are not elected to be designated as measured at FVOCI. As of December 31, 2017, the Company has financial assets at fair value through profit or loss amounting to ₩133,532 million, available-for-sale held-to-maturity Based on the result of the detailed assessment to date, the expected impacts on the Company’s financial assets (excluding derivative instruments) on the date of initial application (January 1, 2018) are as follows: Classification based on IAS 39 Classification based on IFRS 9 Amount based Amount based In millions of won Financial assets at FVTPL FVTPL ₩ 111,512 111,512 Loans and receivables Amortized cost 15,203,663 14,412,339 Loans and receivables FVTPL — 791,324 Available-for-sale FVOCI 699,833 476,941 Available-for-sale FVTPL — 222,892 Held-to-maturity Amortized cost 3,144 3,144 Total financial assets (excluding derivative instruments) ₩ 16,018,152 16,018,152 Upon adoption of IFRS 9, ₩791,324 million of loans and receivables and ₩222,892 million of available-for-sale available-for-sale ② Classification and measurement of financial liabilities Under IFRS 9, the amount of change in the fair value attributable to the changes in the credit risk of the financial liabilities is presented in OCI, not recognized in profit or loss, and the OCI amount will not be reclassified (recycled) to profit or loss. However, if doing so creates or increase an accounting mismatch, the amount of change in the fair value is recognized in profit or loss. The Company did not elect to designate financial liabilities as FVTPL and believes that there is no significant impact on the Company’s consolidated financial statements upon adoption of IFRS 9. ③ Impairment: Financial assets and contract assets IFRS 9 replaces the ‘incurred loss’ model in the existing standard with a forward-looking ‘expected credit loss’ (ECL) model for debt instruments, lease receivables, contractual assets, loan commitments, financial guarantee contracts. Under IFRS 9, impairment losses are likely to be recognized earlier than using the incurred loss model under the existing guidance in IAS 39 as loss allowances will be measured on either of the 12-month Classification Loss allowances Stage 1 Credit risk has not increased significantly since the initial recognition 12-month ECL: ECLs that resulted from possible default events within the 12 months after the reporting date Stage 2 Credit risk has increased significantly since the initial recognition Lifetime ECL: ECL that resulted from all possible default events over the expected life of a financial instrument Stage 3 Credit-impaired Under IFRS 9, an entity shall always measure the loss allowance at an amount equal to lifetime expected credit losses for trade receivables or contract assets that result from transactions that are within the scope of IFRS 15 and that do not contain a significant financing component in accordance with IFRS 15 and if the trade receivables or contract assets include a significant financing component, an entity may choose as its accounting policy to measure the loss allowance at an amount equal to lifetime expected credit losses. As of December 31, 2017, the Company has debt instruments in financial assets measured at amortized cost amounting to ₩15,464,202 million (loans and receivables) and has recognized loss allowances of ₩260,539 million. Under adoption of IFRS 9, the Company plans to elect to measure the loss allowance at an amount equal to lifetime expected credit losses for trade receivables, contract assets and lease receivables that include a significant financing component. Based on the result of the detailed assessment to date, the expected impacts on the Company’s loss allowances on the date of initial application (January 1, 2018) are as follows: Type Amount based on IAS 39 (A) Amount based on IFRS 9 (B) Increase (decrease) (B-A) In millions of won Trade and other receivables ₩ 251,591 258,360 6,769 Other financial assets 8,948 8,948 — Total ₩ 260,539 267,308 6,769 ④ Hedge accounting When initially applying IFRS 9, an entity may elect as its accounting policy to continue to apply the hedge accounting requirements of IAS 39. The Company plans to elect to continue apply the hedge accounting requirements of IAS 39. As of December 31, 2017, the Company has asset and liabilities designated as hedged items amounting to ₩10,606 million and ₩277,130 million, respectively. (ii) IFRS 15 ‘Revenue from Contracts with Customers’ IFRS 15 sets out a comprehensive framework for determining whether revenue is recognized, the extent of revenue recognized, and when revenue is recognized. It replaces existing revenue recognition guidance, including IAS 18 ‘Revenue’, IAS 11 ‘Construction Contracts’, SIC-31 The Company will retrospectively apply and recognize the cumulative effect of the adoption of IFRS 15 at the date of initial application (January 1, 2018) and has determined to retrospectively apply to only those contracts that were not completed as of the date of initial application (January 1, 2018). Accordingly, the Company will not restate the comparative periods. Existing IFRS standards and interpretations including IAS 18 provide revenue recognition guidance by transaction types such as sales of goods, rendering of services, interest income, royalty income, dividend income and construction revenue; however, under the new standard, IFRS 15, the five-step approach (Step 1: Identify the contract(s) with a customer, Step 2: Identify the performance obligations in the contract, Step 3: Determine the transaction price, Step 4: Allocate the transaction price to the performance obligations in the contract, Step 5: Recognize revenue when the entity satisfied a performance obligation) is applied for all types of contracts or agreements. Expected impacts on the consolidated financial statements are categorized as follows: ① Identify the performance obligations in the contract The Company is engaged in the generation, transmission and distribution of electricity and development of electric power resources, and electricity sales revenue accounts for 91.3% of consolidated revenue for the year ended December 31, 2017. Under IFRS 15, supplying electricity is a series of distinct goods or services identified as a single performance obligation. The Company is also engaged in contracts with customers for transmission and distribution, provision of power generation byproducts, EPC business, O&M, etc. that are identified as different performance obligations for each contract. Based on the result of the detailed assessment to date, the Company believes that the impact of identifying separate the performance obligations in the contract on the Company’s revenue is not significant. ② Variable consideration The Company may be subject to a variation of consideration paid by the customer due to the progressive electricity billing system, discounts on electricity bills for policy purposes, penalties and delinquent payment, etc. In applying IFRS 15, the Company estimates an amount of variable consideration by using the expected value method that the Company expects to better predict the amount of consideration to which it will be entitled, and includes in the transaction price some or all of an amount of variable consideration only to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Based on the result of the detailed assessment to date, the Company believes that the impact of variable consideration on the Company’s revenue is not significant. ③ Performance obligations satisfied over time The Company provides its customers with services such as EPC business, O&M, etc. over time. The Company recognizes revenues based on the percentage-of-completion Under IFRS 15, an entity recognizes revenue over time if one of the following criteria is met: (a) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs; (b) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or (c) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. Based on the result of the detailed assessment to date, the impact of the revenue recognition over time based on the percentage-of-completion (iii) IFRS 16 ‘Leases’ IFRS 16 replaces IAS 17 ‘Leases’, and IFRIC 4 ‘Determining whether an Arrangement contains a Lease’. This standard is effective for annual reporting periods beginning on or after January 1, 2019, with early adoption permitted if IFRS 15 ‘Revenue from Contracts with Customers’ has also been applied. Under IFRS 16, a lessee shall apply this standard to its leases either: (a) retrospectively to each prior reporting period presented applying IAS 8 ‘Accounting Policies, Changes in Accounting Estimates and Errors’; or (b) retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company has not yet determined the transition approach for IFRS 16. IFRS 16 provides a single lessee accounting model in which the lessee recognizes lease related assets and liabilities in the statement of financial position. A lessee is required to recognize a right-of-use Upon adoption of IFRS 16, the nature of the costs associated with the lease will change as the operating lease payments recognized based on a straight-line basis will change to depreciation expense of a right-of-use The Company plans to conduct a detailed assessment of the potential impact from the application of IFRS 16 during the year ending December 31, 2018. (iv) IFRIC 22 ‘Foreign Currency Transactions and Advance Consideration’ IFRIC 22, published on December 8, 2016, clarifies the date of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income, when an entity has received or paid advance consideration in a foreign currency. IFRIC 22 is effective for annual reporting periods beginning on or after January 1, 2018, with earlier adoption permitted. The Company is currently performing a detailed assessment of the impact resulting from the application of IFRIC 22 and plans to complete the assessment in advance of its effective date. (v) Amendments to IAS 40 ‘Investment Property’ The amendments clarify when an entity should transfer a property asset to, or from, investment property. The amendments are effective for annual periods beginning on or after January 1, 2018, with earlier adoption permitted. The Company is currently performing a detailed assessment of the impact resulting from the application of amendments to IAS 40 and plans to complete the assessment in advance of its effective date. |

Significant Accounting Policies [Abstract] | |
Significant Accounting Policies | 3. Significant Accounting Policies Except as described in note 2.(5), the Company applied the following significant accounting policies consistently for all periods presented. (1) Basis of consolidation The consolidated financial statements are the financial statements of a group in which the assets, liabilities, equity, income, expenses and cash flows of the parent and its subsidiaries are presented as those of a single economic entity. Subsidiaries are controlled by the Company. The Company controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Income and expense of a subsidiary acquired or disposed of during the year are included in the consolidated statement of comprehensive income from the effective date of acquisition and up to the effective date of disposal, as appropriate. Total comprehensive income of subsidiaries is attributed to the owners of the Company and to the non-controlling non-controlling When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with those of the Company. Transactions within the Company are eliminated during the consolidation. Changes in the Company’s ownership interests in a subsidiary that do not result in the Company losing control over the subsidiary are accounted for as equity transactions. The carrying amounts of the Company’s interests and the non-controlling non-controlling When the Company loses control of a subsidiary, the income or loss on disposal is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling (2) Business combinations A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by the Company, liabilities incurred by the Company to the former owners of the acquiree and the equity interests issued by the Company in exchange for control of the acquiree. Acquisition-related costs are generally recognized in income or loss as incurred. At the acquisition date, the identifiable assets acquired and the liabilities assumed are recognized at their fair value at the acquisition date, except that: • deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements are recognized and measured in accordance with IAS 12 ‘ Income Taxes’ and IAS 19 ‘ Employee Benefits’ respectively; • assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 ‘Non-current Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling non-controlling Non-controlling non-controlling transaction-by-transaction non-controlling The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not re-measured re-measured When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree is re-measured If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period (see above), or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date. The assets and liabilities acquired under business combinations under common control are recognized at the carrying amounts recognized previously in the consolidated financial statements of the ultimate parent. The difference between consideration transferred and carrying amounts of net assets acquired is recognized as part of share premium. (3) Investments in associates An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not control or joint control over those policies. The results and assets and liabilities of associates are incorporated in these consolidated financial statements using the equity method of accounting. If the investment is classified as held for sale, in which case it is accounted for in accordance with IFRS 5 ‘Non-current After the disposal takes place, the Company shall account for any retained interest in associates in accordance with IAS 39 ‘Financial Instruments: Recognition and Measurement’ unless the retained interest continues to be an associates, in which case the entity uses the equity method. Under the equity method, an investment in an associate is initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the income or loss and other comprehensive income of the associate. When the Company’s share of losses of an associate exceeds the Company’s interest in that associate (which includes any long-term interests that, in substance, form part of the Company’s net investment in the associate), the Company discontinues recognizing its share of further losses. Additional losses are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the associate. Any excess of the cost of acquisition over the Company’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities of an associate recognized at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Company’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities over the cost of acquisition, after reassessment, is recognized immediately in income or loss. The requirements of IAS 39 ’Financial Instruments: Recognition and Measurement’, are applied to determine whether it is necessary to recognize any impairment loss with respect to the Company’s investment in an associate. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 ‘Impairment of Assets’ as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount, any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases. Upon disposal of an associate that results in the Company losing significant influence over that associate, any retained investment is measured at fair value at that date and the fair value is regarded as its fair value on initial recognition as a financial asset in accordance with IAS 39. The difference between the previous carrying amount of the associate attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate. In addition, the Company accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate would be reclassified to income or loss on the disposal of the related assets or liabilities, the Company reclassifies the gain or loss from equity to income or loss (as a reclassification adjustment) when it loses significant influence over that associate. When the Company transacts with its associate, incomes and losses resulting from the transactions with the associate are recognized in the Company’s consolidated financial statements only to the extent of interests in the associate that are not related to the Company. (4) Joint arrangements A joint arrangement is an arrangement of which two or more parties have joint control. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Joint arrangements are classified into two types—joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint ventures) have rights to the net assets of the arrangement. If the Company is a joint operator, the Company is to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. If the joint arrangement is a joint venture, the Company is to account for that investment using the equity method accounting in accordance with IAS 28 ‘Investment in Associates and Joint Ventures’ (refer to note 3.(3)), except when the Company is applicable to the IFRS 5 ‘Non-current (5) Non-current Non-current non-current When the Company is committed to a sale plan involving loss of control of a subsidiary, all of the assets and liabilities of that subsidiary are classified as held for sale when the criteria described above are met, regardless of whether the Company will retain a non-controlling Non-current (6) Goodwill The Company measures goodwill which acquired in a business combination at the amount recognized at the date on which it obtains control of the acquiree (acquisition date) less any accumulated impairment losses. Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergies arising from the business acquired. The Company assesses at the end of each reporting period and whenever there is an indication that the asset may be impaired. An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount. Impairment losses are recognized in profit or loss. Any impairment identified at the CGU level will first reduce the carrying value of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. (7) Revenue recognition Revenue from the sale of goods, rendering of services or use of the Company assets is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates, which are recognized as a reduction of revenue. Revenue is recognized when the amount of revenue can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Company. (i) Sales of goods The Korean government approves the utility rates charged to customers by the Company’s power transmission and distribution division. The Company’s utility rates are designed to recover the Company’s reasonable costs plus a fair investment return. The Company recognize revenue from electricity sales revenue based on power sold (transferred to the customer) up to the reporting date and the corresponding utility rate charged to customers. To determine the amount of power sold, the Company estimates daily power volumes of electricity for residential, commercial, general, etc. The differences between the current month’s estimated amount and actual (meter-read) amount, is adjusted for (trued-up) (ii) Sales of services Revenue from services rendered is recognized in profit or loss in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to surveys of work performed or services performed to date as a percentage of total services to be performed or the proportion that costs incurred to date bear to the estimated total costs of the transaction or other methods that reliably measures the services performed. (iii) Dividend income and interest income Dividend income is recognized in profit or loss on the date that the Company’s right to receive payment is established, which in the case of quoted securities is the ex-dividend Interest income is recognized as it accrues in profit or loss, using the effective interest method. Interest income is accrued on a time basis, by reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset’s net carrying amount on initial recognition. (iv) Rental income The Company’s policy for recognition of revenue from operating leases is described in note 3.(9) below. (8) Construction services revenue The Company provides services related to the construction of power plants related to facilities of its customers, mostly in foreign countries. When the outcome of a construction contract can be estimated reliably, revenue and costs are recognized based on the stage of completion of the contract activity at the end of the reporting period, measured based on the proportion of contract costs incurred for work performed to date relative to the estimated total contract costs, except where this would not be representative of the stage of completion. Variations in contract work, claims and incentive payments are included to the extent that the amount can be measured reliably and its receipt is considered probable. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognized to the extent of contract costs incurred when it is probable the revenue will be realized. Contract costs are recognized as expenses in the period in which they are incurred. When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognized as an expense immediately. When contract costs incurred to date plus recognized income less recognized losses exceed progress billings, the surplus is presented as amounts due from customers for contract work. For contracts where progress billings exceed contract costs incurred to date plus recognized income less recognized losses, the surplus is presented as the amounts due to customers for contract work. Amounts received before the related work is performed are included in the consolidated statements of financial position, as a liability, as advance received. Amounts billed for work performed but not yet paid by the customer are included in the consolidated statements of financial position as accounts and other receivables. (9) Leases The Company classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the Company assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. (i) The Company as lessor Amounts due from lessees under finance leases are recognized as receivables at the amount of the Company’s net investment in the leases. Finance lease income is allocated to accounting periods so as to reflect a constant periodic rate of return on the Company’s net investment outstanding in respect of the leases. Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized on a straight-line basis over the lease term. (ii) The Company as lessee Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases. Assets held under finance leases are initially recognized as assets of the Company at their fair value at the inception of the lease or, if lower, at the present value of the minimum lease payments. The corresponding liability to the lessor is included in the statement of financial position as a finance lease obligation. Lease payments are apportioned between finance expenses and reduction of the lease obligation so as to achieve a constant rate of interest on the remaining balance of the liability. Finance expenses are recognized immediately in income or loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Company’s general policy on borrowing costs. Contingent rentals are recognized as expenses in the periods in which they are incurred. Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred. In the event that lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. (iii) Determining whether an arrangement contains a lease At inception of an arrangement, the Company determines whether the arrangement is or contains a lease. At inception or on reassessment of an arrangement that contains a lease, the Company separates payments and other consideration required by the arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Company concludes for a finance lease that it is impracticable to separate the payments reliably, then an asset and a liability are recognized at an amount equal to the fair value of the underlying asset. (10) Foreign currencies Transactions in foreign currencies are translated to the respective functional currencies of the Company entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the reporting date’s exchange rate. Non-monetary Exchange differences are recognized in profit or loss in the period in which they arise except for: • Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings; • Exchange differences on transactions entered into in order to hedge certain foreign currency risks (refer to note 3.(25) Derivative financial instruments, including hedge accounting); and • Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to income or loss on disposal or partial disposal of the net investment. For the purpose of presenting financial statements, the assets and liabilities of the Company’s foreign operations are expressed in Korean won using exchange rates prevailing at the end of the reporting period. Income and expense items are translated at the average exchange rates for the period, unless exchange rates fluctuated significantly during that period, in which case the exchange rates at the dates of the transactions are used. Exchange differences arising, if any, are recognized in other comprehensive income and accumulated in equity. When a foreign operation is disposed of, the relevant amount in the translation is transferred to profit or loss as part of the gain or loss on disposal. (11) Borrowing costs The Company capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in income or loss in the period in which they are incurred. (12) Government grants and income related to transfer of assets from customers Government grants are not recognized unless there is reasonable assurance that the Company will comply with the grant’s conditions and that the grant will be received. Benefit from a government loan at a below-market interest rate is treated as a government grant, measured as the difference between proceeds received and the fair value of the loan based on prevailing market interest rates. (i) If the Company received grants related to assets Government grants whose primary condition is that the Company purchase, construct or otherwise acquire long-term assets are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduced depreciation expense. (ii) If the Company received grants related to income Government grants which are intended to compensate the Company for expenses incurred are recognized as other income (government grants) in profit or loss over the periods in which the Company recognizes the related costs as expenses. The Company recovers a substantial amount of the cost related to its electric power distribution facilities from customers through the transfer of assets, while the remaining portion is recovered through electricity sales from such customers in the future. As such, the Company believes there exists a continued service obligation to the customers in accordance with IFRIC 18 ‘Transfer of Assets from Customers’ when the Company receives an item of property, equipment, or cash for constructing or acquiring an item of property or equipment, in exchange for supplying electricity to customers. The Company defers the amounts received, which are subsequently recognized as other income on a straight-line basis over the estimated service period which does not exceed the transferred asset’s useful life. (13) Employee benefits When an employee has rendered service to the Company during a period, the Company recognizes the contribution payable to a defined contribution plan in exchange for that service as a liability (accrued expense). For defined benefit pension plans and other post-employment benefits, the net periodic pension expense is actuarially determined by “Pension Actuarial System” developed by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. However, if there is not a deep market, market yields on government bonds are used. Net defined benefit liability’s measurement is composed of actuarial gains and losses, return on plan assets excluding net interest on net defined benefit liability, and any change in the effect of the asset ceiling, excluding net interest, which are immediately recognized in other comprehensive income. The actuarial gains or losses recognized in other comprehensive income which will not be reclassified into net profit or loss for later periods are immediately recognized in retained earnings. Past service cost will be recognized as expenses upon the earlier of the date of change or reduction to the plan, or the date of recognizing termination benefits. The retirement benefit obligation recognized in the statement of financial position represents the present value of the defined benefit obligation as adjusted for unrecognized actuarial gains and losses and unrecognized past service cost, and as reduced by the fair value of plan assets. Any asset resulting from this calculation is limited to unrecognized actuarial losses and past service cost, plus the present value of available refunds and reductions in future contributions to the plan. (14) Income taxes Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income. (i) Current tax Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period and any adjustment to tax payable in respect of previous years. The taxable profit is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and non-taxable non-deductible (ii) Deferred tax Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. A deferred tax liability is recognized for all taxable temporary differences. A deferred tax asset is recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilized. However, deferred tax is not recognized for the following temporary differences: taxable temporary differences arising on the initial recognition of goodwill, or the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting profit or loss nor taxable income. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets or deferred tax liabilities on investment properties measured at fair value, unless any contrary evidence exists, are measured using the assumption that the carrying amount of the property will be recovered entirely through sale. The Company recognizes a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint ventures, except to the extent that the Company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Company recognizes a deferred tax asset for all deductible temporary differences arising from investments in subsidiaries and associates, to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized. The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset only if there is a legally enforceable right to offset the related current tax liabilities and assets, and they relate to income taxes levied by the same tax authority and they intend to settle current tax liabilities and assets on a net basis. (iii) Current and deferred tax for the year Current and deferred tax are recognized in income or loss, except when they relate to items that are recognized in other comprehensive income or directly in equity, in which case, the current and deferred tax are also recognized in other comprehensive income or directly in equity respectively. Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination. (15) Property, plant and equipment Property, plant and equipment are initially measured at cost and after initial recognition, are carried at cost less accumulated depreciation and accumulated impairment losses. The cost of property, plant and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Subsequent costs are recognized in the carrying amount of property, plant and equipment at cost or, if appropriate, as separate items if it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day Property, plant and equipment, except for land, are depreciated on a straight-line basis over estimated useful lives that appropriately reflect the pattern in which the asset’s future economic benefits are expected to be consumed. For loaded nuclear fuel related to long-term raw materials and spent nuclear fuels related to asset retirement costs, the Company uses the production method to measure and recognizes as expense the economic benefits of the assets. The estimated useful lives of the Company’s property, plant and equipment are as follows: Useful lives (years) Buildings 8 ~ 40 Structures 8 ~ 50 Machinery 2 ~ 32 Vehicles 3 ~ 8 Loaded heavy water 30 Asset retirement costs 18, 30, 40, 60 Finance lease assets 6 ~ 32 Ships 9 Others 4 ~ 15 A component that is significant compared to the total cost of property, plant and equipment is depreciated over its separate useful life. Depreciation methods, residual values and useful lives of property, plant and equipment are reviewed at the end of each reporting period and if change is deemed appropriate, it is treated as a change in accounting estimate. As a result of such annual review, useful lives of cer |

Segment, Geographic and Other Information | 4. Segment, Geographic and Other Information (1) Segment determination and explanation of the measurements The Company’s operating segments are its business components that generate discrete financial information that is reported to and regularly reviewed by the Company’s the chief operating decision maker, the Chief Executive Officer, for the purpose of resource allocation and assessment of segment performance. The Company’s reportable segments are ‘Transmission and distribution’, ‘Electric power generation (Nuclear)’, ‘Electric power generation (Non-nuclear)’, Segment operating profit (loss) is determined the same way that consolidated operating profit is determined under IFRS without any adjustment for corporate allocations. The accounting policies used by each segment are consistent with the accounting policies used in the preparation of the consolidated financial statements. Segment assets and liabilities are determined based on separate financial statements of the entities instead of on a consolidated basis. There are various transactions between the reportable segments, including sales of property, plant and equipment and so on, that are conducted on an arms-length basis at market prices that would be applicable to an independent third-party. For subsidiaries which are in a different segment from that of its immediate parent company, their carrying amount in separate financial statements is eliminated in the consolidating adjustments in the tables below. In addition, consolidation adjustments in the table below include adjustments of the amount of investment in associates and joint ventures from the cost basis amount reflected in segment assets to that determined using equity method in the consolidated financial statements. (2) Financial information of the segments for the years ended December 31, 2015, 2016 and 2017, respectively, are as follows: 2015 Segment Total Intersegment Revenue Depreciation Interest Interest

Contingencies and Commitments | 50. Contingencies and Commitments (1) Ongoing litigations related with contingent liabilities and contingent assets as of December 31, 2016 and 2017 are as follows: 2016 2017 Number Claim Number Claim In millions of won As the defendant 675 ₩ 636,433 565 ₩ 477,719 As the plaintiff 193 489,605 185 690,934 As of December 31, 2017, among the litigations mentioned above, there are ongoing litigations of Korea Hydro & Nuclear Power Co., Ltd. (“KHNP”), a subsidiary of KEPCO, against KEPCO Engineering & Construction Company, Inc., a subsidiary of KEPCO, as a co-defendant A group of plaintiffs (consisting 2,167 individuals) filed a lawsuit against NSSC regarding NSSC’s approval on May 18, 2015 of extending the operation of Wolsong Unit 1 nuclear power plant. The appeal was ongoing as of December 31, 2017. Also, Greenpeace and others filed an administrative litigation against NSSC requesting cancelation of the construction permit of Shin-Kori Unit 5 and 6 it was ongoing as of December 31, 2017. The Company joined these litigations as a stakeholder with the permission of the Court. The book value of property, plant and equipment and provision for decommissioning costs of Wolsong Unit 1 nuclear power plant is ₩607,967 million and ₩642,015 million, respectively, as of December 31, 2017. If the continuance of operation of Wolsong Unit 1 nuclear power plant is annulled, significant losses may be incurred in connection with the property, plant and equipment of Wolsong Unit 1. In addition, the amount of provision may increase significantly, and the timing of actual cash outflows may be accelerated. The Company suspended the construction of Shin-Kori Unit 5 and 6 starting from July 24, 2017 to October 24, 2017, which is the public debate period regarding whether to continue the construction for Shin-Kori Unit 5 and 6, and is in the process of reviewing the appropriateness of the additional costs requested by the suppliers that occurred during that period. The Company believes that the possibility of economic outflow is probable and recognized ₩77,261 million of provision as described in note 26.(2). As of December 31, 2017, the Company has suspended the construction design of Shin-Hanwool Unit 3 and 4. The construction contract amount and the outstanding balance are described in note 49.(1), and the carrying amount of Shin-Hanwool Unit 3 and 4 is ₩ The Company is the defendant against a number of claims. The followings are potentially significant claims pertaining to the Company. ① Hyundai Engineering & Construction Co., Ltd.(“Hyundai E&C”), SK Engineering & Construction Co., Ltd. and GS Engineering & Construction Co., Ltd. filed a lawsuit for increase in contract bill (formerly, amounted to ₩1,000 million) against KHNP in September 2013, in relation to the design changes on the plant construction of Shin-Hanwool 1 & 2. Hyundai Engineering & Construction Co., Ltd. and two other companies increased the contract bill to ₩133,426 million in October 2014, ₩204,040 million in November 2015, and ₩204,564 million in January 2017, respectively, and submitted an application to demand extra contract payments due to the design changes. KHNP has paid ₩217,724 million of the claim amounts in full upon the first ruling in November 2016 and recognized the amount as addition to construction-in-progress ② In December 2013, the Supreme Court of Korea ruled that regular bonuses also fall under the category of ordinary wages on the condition that those bonuses are paid regularly and uniformly. Also, the Supreme Court ruled that employees are entitled to retroactively demand certain wages based on the new ordinary wages that include regular bonuses as additional wages. However, the request may be limited to the extent of the principle of good faith. The Company believes that the possibility of economic outflow is probable on the ongoing and the expected lawsuit. For this reason, the Company recognized ₩56,052 million of other provision in relation to the lawsuit as of December 31, 2017. Except these significant ongoing claims, there are 10 arbitration cases pertaining to the Company as of December 31, 2017 and the significant arbitration cases are as follows: ① KEPCO and KEPCO KDN Co., Ltd., a subsidiary of KEPCO, have been accused of breach of contract in relation to ERP software, which is provided by SAP Korea Ltd. The litigation was filed in the International Chamber of Commerce International Court of Arbitration but the Company has not recognized any provision because the probability of economic benefit outflow is remote and the related amount cannot be reliably estimated. ② Hyundai Samsung Joint Venture (HSJV), one of the subcontractors of the Company, filed an arbitration against the Company at the London Court of International Arbitration (LCIA) in 2016 due to disagreements in UAE nuclear power plant construction project, but the Company has not recognized any losses because the probability of economic benefit outflow is remote and the related amount cannot be reasonably estimated. ③ In prior years, Hyundai E&C, GS Engineering & Construction Corp., and Hansol SeenTec Co., Ltd. filed on arbitration against the Company to the Korea Commercial Arbitration Board in relation to the request for additional construction costs but the Company has not recognized any provision because the probability of economic benefit outflow is remote and the related amount cannot be reliably estimated. ④ In prior years, Halla Corporation filed on arbitration against the Company to the Korea Commercial Arbitration Board in relation to the request for additional construction costs and the Company filed on arbitration against Halla Corporation to the Korea Commercial Arbitration Board in relation to the request for a penalty payment for the delayed construction work. The Company has recognized ₩4,916 million of provision for the best estimate of the expenditure required to fulfill its obligations in relation to this arbitration as of December 31, 2017. (2) Guarantees of borrowings provided to other companies as of December 31, 2016 and 2017 are as follows: ① In order to secure its status as a shareholder of Navanakorn Electric Co., Ltd., the Company has signed a fund supplement contract.

Basis of Preparation [Abstract] | |
Statement of compliance | These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). |
Basis of measurement | Basis of measurement These consolidated financial statements have been prepared on the historical cost basis, except for the following material items in the consolidated statements of financial position: • derivative financial instruments are measured at fair value • available-for-sale • liabilities for defined benefit plans are recognized at the net of the total present value of defined benefit obligations less the fair value of plan assets |
Functional and presentation currency | Functional and presentation currency These consolidated financial statements are presented in Korean won (“Won”), which is KEPCO’s functional and presentation currency. |
Use of estimates and judgments | The preparation of the consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. The following are the key assumptions concerning the future, and other key sources of estimation uncertainty at the end of the reporting period, that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year. (i) Unbilled revenue Energy delivered but not metered nor billed are calculated at the reporting date and is estimated based on consumption statistics and selling price estimates. Determination of the unbilled revenues at the end of the reporting period is sensitive to the estimated consumptions and prices based on statistics. Unbilled revenue recognized for the years ended December 31, 2016 and 2017 are ₩1,615,322 million and ₩1,672,385 million, respectively. (ii) Continuing operation of Wolsong Unit 1 nuclear power plant Wolsong Unit 1 nuclear power plant of the Company commenced operations on November 21, 1982 and its 30-year According to the Eighth Basic Plan for Electricity Supply and Demand by the Ministry of Trade, Industry and Energy, Wolsong Unit 1 nuclear power plant is expected to go through a comprehensive evaluation for the feasibility of continuous operation including economic efficiency and acceptability of household and community in 2018. The Korean government plans to refund to the Company for reasonable expenditures incurred in relation to the phase-out Information about critical judgments in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes: • Note 17 – Investments in Associates and Joint Ventures • Note 18 – Property, Plant and Equipment • Note 20 – Construction Services Contracts • Note 45 – Risk Management Information about assumptions and estimation uncertainties that have a significant risk of resulting in a material adjustment within the next financial year is included in the following notes: • Note 41 – Income Taxes • Note 25 – Employment Benefits |
Changes in accounting policies | (i) Amendments to to IAS 7 ‘Statement of Cash Flows’ The Company has adopted amendments to IAS ‘Statement of Cash Flows’ since January 1, 2017. The amendments require changes in liabilities arising from financing activities to be disclosed. The amendments are not required to provide comparative information for prior periods when applying for the first time. Information about changes in liabilities arising from financing activities is included in note 23 and note 24. (ii) Amendments to IAS 12 ‘Income Taxes’ The Company has adopted amendments to IAS 12 ‘Income Taxes’ since January 2017. The amendments clarify that unrealized losses on fixed-rate debt instruments measured at fair value and measured at cost for tax purposes give rise to a deductible temporary difference regardless of whether the holder expects to recover the carrying amount of the debt instrument by sale or by use and that the estimate of probable future taxable profit may include the recovery of some of assets for more than their carrying amount. When the Company assesses whether there will be sufficient taxable profit, the Company should compare the deductible temporary differences with future taxable profit that excludes tax deductions resulting from the reversal of those deductible temporary differences. The Company believes that there is no significant impact on the Company’s consolidated financial statements and did not retroactively restate the comparative consolidated financial statements for the prior period. |
New standards and amendments not yet adopted | New standards and amendments not yet adopted The following new standards, including IFRS 9 ‘Financial Instruments’ and IFRS 15 ‘Revenue from Contracts with Customers’, interpretations and amendments to existing standards have been published but are not mandatory for the Company for annual periods beginning on January 1, 2017, and the Company has not early adopted them. The Company will apply IFRS 9 ‘Financial Instruments’ and IFRS 15 ‘Revenue from Contracts with Customers’ for annual periods beginning on January 1, 2018. The Company has conducted a detailed assessment on adoption of these standards and based on the circumstance and information available when these financial statements were authorized for issuance. (i) IFRS 9 ‘Financial Instruments’ IFRS 9 sets out the requirements for recognizing and measuring financial assets, financial liabilities and certain contracts to buy or sell non-financial The Company will apply the exemption allowing it not to restate the comparative information for prior periods upon adoption of IFRS 9. The Company will retroactively apply the cumulative effect of the adoption of IFRS 9 in retained earnings as of the date of initial application (January 1, 2018). Expected impacts on the consolidated financial statements are categorized as follows: ① Classification and measurement of financial assets IFRS 9 includes a new classification and measurement of financial assets that reflects the business model in which assets are managed and their cash flow characteristics. Under IFRS 9, financial assets are classified into three principal categories; measured at amortized cost, fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVTPL) based on the business model in which assets are managed and their cash flow characteristics. Under IFRS 9, derivatives embedded in hybrid contracts where the host is a financial asset are not bifurcated. Instead, the hybrid financial instrument as a whole is assessed for classification. The criteria for classification and measurement of financial assets under IFRS 9 are as follows: • A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL: 1) the asset is held within a business model whose objective is to hold assets to collect contractual cash flows; and 2) the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. • A financial asset is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL: 1) the asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets; and 2) the contractual terms of the financial asset give rise on specified dates to cash flow that are solely payments of principal and interest on the principal amount outstanding. On initial recognition of equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in fair value in OCI, and will not reclassify(recycle) the those items in OCI to profit or loss subsequently. • A financial asset is measured at FVTPL if the contractual terms of the financial asset give rise to specified dates to cash flows that are not solely payments of principal and interest on the principal amount outstanding, the debt instrument is held within a business model whose objective is to sell the asset, or the equity instruments that are not elected to be designated as measured at FVOCI. As of December 31, 2017, the Company has financial assets at fair value through profit or loss amounting to ₩133,532 million, available-for-sale held-to-maturity Based on the result of the detailed assessment to date, the expected impacts on the Company’s financial assets (excluding derivative instruments) on the date of initial application (January 1, 2018) are as follows: Classification based on IAS 39 Classification based on IFRS 9 Amount based Amount based In millions of won Financial assets at FVTPL FVTPL ₩ 111,512 111,512 Loans and receivables Amortized cost 15,203,663 14,412,339 Loans and receivables FVTPL — 791,324 Available-for-sale FVOCI 699,833 476,941 Available-for-sale FVTPL — 222,892 Held-to-maturity Amortized cost 3,144 3,144 Total financial assets (excluding derivative instruments) ₩ 16,018,152 16,018,152 Upon adoption of IFRS 9, ₩791,324 million of loans and receivables and ₩222,892 million of available-for-sale available-for-sale ② Classification and measurement of financial liabilities Under IFRS 9, the amount of change in the fair value attributable to the changes in the credit risk of the financial liabilities is presented in OCI, not recognized in profit or loss, and the OCI amount will not be reclassified (recycled) to profit or loss. However, if doing so creates or increase an accounting mismatch, the amount of change in the fair value is recognized in profit or loss. The Company did not elect to designate financial liabilities as FVTPL and believes that there is no significant impact on the Company’s consolidated financial statements upon adoption of IFRS 9. ③ Impairment: Financial assets and contract assets IFRS 9 replaces the ‘incurred loss’ model in the existing standard with a forward-looking ‘expected credit loss’ (ECL) model for debt instruments, lease receivables, contractual assets, loan commitments, financial guarantee contracts. Under IFRS 9, impairment losses are likely to be recognized earlier than using the incurred loss model under the existing guidance in IAS 39 as loss allowances will be measured on either of the 12-month Classification Loss allowances Stage 1 Credit risk has not increased significantly since the initial recognition 12-month ECL: ECLs that resulted from possible default events within the 12 months after the reporting date Stage 2 Credit risk has increased significantly since the initial recognition Lifetime ECL: ECL that resulted from all possible default events over the expected life of a financial instrument Stage 3 Credit-impaired Under IFRS 9, an entity shall always measure the loss allowance at an amount equal to lifetime expected credit losses for trade receivables or contract assets that result from transactions that are within the scope of IFRS 15 and that do not contain a significant financing component in accordance with IFRS 15 and if the trade receivables or contract assets include a significant financing component, an entity may choose as its accounting policy to measure the loss allowance at an amount equal to lifetime expected credit losses. As of December 31, 2017, the Company has debt instruments in financial assets measured at amortized cost amounting to ₩15,464,202 million (loans and receivables) and has recognized loss allowances of ₩260,539 million. Under adoption of IFRS 9, the Company plans to elect to measure the loss allowance at an amount equal to lifetime expected credit losses for trade receivables, contract assets and lease receivables that include a significant financing component. Based on the result of the detailed assessment to date, the expected impacts on the Company’s loss allowances on the date of initial application (January 1, 2018) are as follows: Type Amount based on IAS 39 (A) Amount based on IFRS 9 (B) Increase (decrease) (B-A) In millions of won Trade and other receivables ₩ 251,591 258,360 6,769 Other financial assets 8,948 8,948 — Total ₩ 260,539 267,308 6,769 ④ Hedge accounting When initially applying IFRS 9, an entity may elect as its accounting policy to continue to apply the hedge accounting requirements of IAS 39. The Company plans to elect to continue apply the hedge accounting requirements of IAS 39. As of December 31, 2017, the Company has asset and liabilities designated as hedged items amounting to ₩10,606 million and ₩277,130 million, respectively. (ii) IFRS 15 ‘Revenue from Contracts with Customers’ IFRS 15 sets out a comprehensive framework for determining whether revenue is recognized, the extent of revenue recognized, and when revenue is recognized. It replaces existing revenue recognition guidance, including IAS 18 ‘Revenue’, IAS 11 ‘Construction Contracts’, SIC-31 The Company will retrospectively apply and recognize the cumulative effect of the adoption of IFRS 15 at the date of initial application (January 1, 2018) and has determined to retrospectively apply to only those contracts that were not completed as of the date of initial application (January 1, 2018). Accordingly, the Company will not restate the comparative periods. Existing IFRS standards and interpretations including IAS 18 provide revenue recognition guidance by transaction types such as sales of goods, rendering of services, interest income, royalty income, dividend income and construction revenue; however, under the new standard, IFRS 15, the five-step approach (Step 1: Identify the contract(s) with a customer, Step 2: Identify the performance obligations in the contract, Step 3: Determine the transaction price, Step 4: Allocate the transaction price to the performance obligations in the contract, Step 5: Recognize revenue when the entity satisfied a performance obligation) is applied for all types of contracts or agreements. Expected impacts on the consolidated financial statements are categorized as follows: ① Identify the performance obligations in the contract The Company is engaged in the generation, transmission and distribution of electricity and development of electric power resources, and electricity sales revenue accounts for 91.3% of consolidated revenue for the year ended December 31, 2017. Under IFRS 15, supplying electricity is a series of distinct goods or services identified as a single performance obligation. The Company is also engaged in contracts with customers for transmission and distribution, provision of power generation byproducts, EPC business, O&M, etc. that are identified as different performance obligations for each contract. Based on the result of the detailed assessment to date, the Company believes that the impact of identifying separate the performance obligations in the contract on the Company’s revenue is not significant. ② Variable consideration The Company may be subject to a variation of consideration paid by the customer due to the progressive electricity billing system, discounts on electricity bills for policy purposes, penalties and delinquent payment, etc. In applying IFRS 15, the Company estimates an amount of variable consideration by using the expected value method that the Company expects to better predict the amount of consideration to which it will be entitled, and includes in the transaction price some or all of an amount of variable consideration only to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Based on the result of the detailed assessment to date, the Company believes that the impact of variable consideration on the Company’s revenue is not significant. ③ Performance obligations satisfied over time The Company provides its customers with services such as EPC business, O&M, etc. over time. The Company recognizes revenues based on the percentage-of-completion Under IFRS 15, an entity recognizes revenue over time if one of the following criteria is met: (a) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs; (b) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or (c) the entity’s performance does not create an asset with an alternative use to the entity and the entity has an enforceable right to payment for performance completed to date. Based on the result of the detailed assessment to date, the impact of the revenue recognition over time based on the percentage-of-completion (iii) IFRS 16 ‘Leases’ IFRS 16 replaces IAS 17 ‘Leases’, and IFRIC 4 ‘Determining whether an Arrangement contains a Lease’. This standard is effective for annual reporting periods beginning on or after January 1, 2019, with early adoption permitted if IFRS 15 ‘Revenue from Contracts with Customers’ has also been applied. Under IFRS 16, a lessee shall apply this standard to its leases either: (a) retrospectively to each prior reporting period presented applying IAS 8 ‘Accounting Policies, Changes in Accounting Estimates and Errors’; or (b) retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company has not yet determined the transition approach for IFRS 16. IFRS 16 provides a single lessee accounting model in which the lessee recognizes lease related assets and liabilities in the statement of financial position. A lessee is required to recognize a right-of-use Upon adoption of IFRS 16, the nature of the costs associated with the lease will change as the operating lease payments recognized based on a straight-line basis will change to depreciation expense of a right-of-use The Company plans to conduct a detailed assessment of the potential impact from the application of IFRS 16 during the year ending December 31, 2018. (iv) IFRIC 22 ‘Foreign Currency Transactions and Advance Consideration’ IFRIC 22, published on December 8, 2016, clarifies the date of the transaction for the purpose of determining the exchange rate to use on initial recognition of the related asset, expense or income, when an entity has received or paid advance consideration in a foreign currency. IFRIC 22 is effective for annual reporting periods beginning on or after January 1, 2018, with earlier adoption permitted. The Company is currently performing a detailed assessment of the impact resulting from the application of IFRIC 22 and plans to complete the assessment in advance of its effective date. (v) Amendments to IAS 40 ‘Investment Property’ The amendments clarify when an entity should transfer a property asset to, or from, investment property. The amendments are effective for annual periods beginning on or after January 1, 2018, with earlier adoption permitted. The Company is currently performing a detailed assessment of the impact resulting from the application of amendments to IAS 40 and plans to complete the assessment in advance of its effective date. |

Significant Accounting Policies [Abstract] | |
Basis of consolidation | The consolidated financial statements are the financial statements of a group in which the assets, liabilities, equity, income, expenses and cash flows of the parent and its subsidiaries are presented as those of a single economic entity. Subsidiaries are controlled by the Company. The Company controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. Income and expense of a subsidiary acquired or disposed of during the year are included in the consolidated statement of comprehensive income from the effective date of acquisition and up to the effective date of disposal, as appropriate. Total comprehensive income of subsidiaries is attributed to the owners of the Company and to the non-controlling non-controlling When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with those of the Company. Transactions within the Company are eliminated during the consolidation. Changes in the Company’s ownership interests in a subsidiary that do not result in the Company losing control over the subsidiary are accounted for as equity transactions. The carrying amounts of the Company’s interests and the non-controlling non-controlling When the Company loses control of a subsidiary, the income or loss on disposal is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling |
Business combinations | Business combinations A business combination is accounted for by applying the acquisition method, unless it is a combination involving entities or businesses under common control. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by the Company, liabilities incurred by the Company to the former owners of the acquiree and the equity interests issued by the Company in exchange for control of the acquiree. Acquisition-related costs are generally recognized in income or loss as incurred. At the acquisition date, the identifiable assets acquired and the liabilities assumed are recognized at their fair value at the acquisition date, except that: • deferred tax assets or liabilities and liabilities or assets related to employee benefit arrangements are recognized and measured in accordance with IAS 12 ‘ Income Taxes’ and IAS 19 ‘ Employee Benefits’ respectively; • assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 ‘Non-current Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling non-controlling Non-controlling non-controlling transaction-by-transaction non-controlling The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not re-measured re-measured When a business combination is achieved in stages, the Company’s previously held equity interest in the acquiree is re-measured If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period (see above), or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed at the acquisition date that, if known, would have affected the amounts recognized at that date. The assets and liabilities acquired under business combinations under common control are recognized at the carrying amounts recognized previously in the consolidated financial statements of the ultimate parent. The difference between consideration transferred and carrying amounts of net assets acquired is recognized as part of share premium. |
Investments in associates | An associate is an entity over which the Company has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but does not control or joint control over those policies. The results and assets and liabilities of associates are incorporated in these consolidated financial statements using the equity method of accounting. If the investment is classified as held for sale, in which case it is accounted for in accordance with IFRS 5 ‘Non-current After the disposal takes place, the Company shall account for any retained interest in associates in accordance with IAS 39 ‘Financial Instruments: Recognition and Measurement’ unless the retained interest continues to be an associates, in which case the entity uses the equity method. Under the equity method, an investment in an associate is initially recognized in the consolidated statement of financial position at cost and adjusted thereafter to recognize the Company’s share of the income or loss and other comprehensive income of the associate. When the Company’s share of losses of an associate exceeds the Company’s interest in that associate (which includes any long-term interests that, in substance, form part of the Company’s net investment in the associate), the Company discontinues recognizing its share of further losses. Additional losses are recognized only to the extent that the Company has incurred legal or constructive obligations or made payments on behalf of the associate. Any excess of the cost of acquisition over the Company’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities of an associate recognized at the date of acquisition is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Company’s share of the net fair value of the identifiable assets, liabilities and contingent liabilities over the cost of acquisition, after reassessment, is recognized immediately in income or loss. The requirements of IAS 39 ’Financial Instruments: Recognition and Measurement’, are applied to determine whether it is necessary to recognize any impairment loss with respect to the Company’s investment in an associate. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 ‘Impairment of Assets’ as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs to sell) with its carrying amount, any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases. Upon disposal of an associate that results in the Company losing significant influence over that associate, any retained investment is measured at fair value at that date and the fair value is regarded as its fair value on initial recognition as a financial asset in accordance with IAS 39. The difference between the previous carrying amount of the associate attributable to the retained interest and its fair value is included in the determination of the gain or loss on disposal of the associate. In addition, the Company accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate would be reclassified to income or loss on the disposal of the related assets or liabilities, the Company reclassifies the gain or loss from equity to income or loss (as a reclassification adjustment) when it loses significant influence over that associate. When the Company transacts with its associate, incomes and losses resulting from the transactions with the associate are recognized in the Company’s consolidated financial statements only to the extent of interests in the associate that are not related to the Company. |
Joint arrangements | Joint arrangements A joint arrangement is an arrangement of which two or more parties have joint control. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Joint arrangements are classified into two types—joint operations and joint ventures. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets, and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement (i.e. joint ventures) have rights to the net assets of the arrangement. If the Company is a joint operator, the Company is to recognize and measure the assets and liabilities (and recognize the related revenues and expenses) in relation to its interest in the arrangement in accordance with relevant IFRSs applicable to the particular assets, liabilities, revenues and expenses. If the joint arrangement is a joint venture, the Company is to account for that investment using the equity method accounting in accordance with IAS 28 ‘Investment in Associates and Joint Ventures’ (refer to note 3.(3)), except when the Company is applicable to the IFRS 5 ‘Non-current |
Non-current assets held for sale | Non-current Non-current non-current When the Company is committed to a sale plan involving loss of control of a subsidiary, all of the assets and liabilities of that subsidiary are classified as held for sale when the criteria described above are met, regardless of whether the Company will retain a non-controlling Non-current |
Goodwill | Goodwill The Company measures goodwill which acquired in a business combination at the amount recognized at the date on which it obtains control of the acquiree (acquisition date) less any accumulated impairment losses. Goodwill acquired in a business combination is allocated to each CGU that is expected to benefit from the synergies arising from the business acquired. The Company assesses at the end of each reporting period and whenever there is an indication that the asset may be impaired. An impairment loss is recognized if the carrying amount of an asset or a CGU exceeds its recoverable amount. Impairment losses are recognized in profit or loss. Any impairment identified at the CGU level will first reduce the carrying value of goodwill and then be used to reduce the carrying amount of the other assets in the CGU on a pro rata basis. Except for impairment losses in respect of goodwill which are never reversed, an impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized. |
Revenue recognition | Revenue from the sale of goods, rendering of services or use of the Company assets is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates, which are recognized as a reduction of revenue. Revenue is recognized when the amount of revenue can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Company. (i) Sales of goods The Korean government approves the utility rates charged to customers by the Company’s power transmission and distribution division. The Company’s utility rates are designed to recover the Company’s reasonable costs plus a fair investment return. The Company recognize revenue from electricity sales revenue based on power sold (transferred to the customer) up to the reporting date and the corresponding utility rate charged to customers. To determine the amount of power sold, the Company estimates daily power volumes of electricity for residential, commercial, general, etc. The differences between the current month’s estimated amount and actual (meter-read) amount, is adjusted for (trued-up) (ii) Sales of services Revenue from services rendered is recognized in profit or loss in proportion to the stage of completion of the transaction at the reporting date. The stage of completion is assessed by reference to surveys of work performed or services performed to date as a percentage of total services to be performed or the proportion that costs incurred to date bear to the estimated total costs of the transaction or other methods that reliably measures the services performed. (iii) Dividend income and interest income Dividend income is recognized in profit or loss on the date that the Company’s right to receive payment is established, which in the case of quoted securities is the ex-dividend Interest income is recognized as it accrues in profit or loss, using the effective interest method. Interest income is accrued on a time basis, by reference to the principal outstanding and at the effective interest rate applicable, which is the rate that exactly discounts estimated future cash receipts through the expected life of the financial asset to that asset’s net carrying amount on initial recognition. (iv) Rental income The Company’s policy for recognition of revenue from operating leases is described in note 3.(9) below. |
Construction services revenue | The Company provides services related to the construction of power plants related to facilities of its customers, mostly in foreign countries. When the outcome of a construction contract can be estimated reliably, revenue and costs are recognized based on the stage of completion of the contract activity at the end of the reporting period, measured based on the proportion of contract costs incurred for work performed to date relative to the estimated total contract costs, except where this would not be representative of the stage of completion. Variations in contract work, claims and incentive payments are included to the extent that the amount can be measured reliably and its receipt is considered probable. When the outcome of a construction contract cannot be estimated reliably, contract revenue is recognized to the extent of contract costs incurred when it is probable the revenue will be realized. Contract costs are recognized as expenses in the period in which they are incurred. When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognized as an expense immediately. When contract costs incurred to date plus recognized income less recognized losses exceed progress billings, the surplus is presented as amounts due from customers for contract work. For contracts where progress billings exceed contract costs incurred to date plus recognized income less recognized losses, the surplus is presented as the amounts due to customers for contract work. Amounts received before the related work is performed are included in the consolidated statements of financial position, as a liability, as advance received. Amounts billed for work performed but not yet paid by the customer are included in the consolidated statements of financial position as accounts and other receivables. |
Leases | The Company classifies and accounts for leases as either a finance or operating lease, depending on the terms. Leases where the Company assumes substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases. (i) The Company as lessor Amounts due from lessees under finance leases are recognized as receivables at the amount of the Company’s net investment in the leases. Finance lease income is allocated to accounting periods so as to reflect a constant periodic rate of return on the Company’s net investment outstanding in respect of the leases. Rental income from operating leases is recognized on a straight-line basis over the term of the relevant lease. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized on a straight-line basis over the lease term. (ii) The Company as lessee Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases. Assets held under finance leases are initially recognized as assets of the Company at their fair value at the inception of the lease or, if lower, at the present value of the minimum lease payments. The corresponding liability to the lessor is included in the statement of financial position as a finance lease obligation. Lease payments are apportioned between finance expenses and reduction of the lease obligation so as to achieve a constant rate of interest on the remaining balance of the liability. Finance expenses are recognized immediately in income or loss, unless they are directly attributable to qualifying assets, in which case they are capitalized in accordance with the Company’s general policy on borrowing costs. Contingent rentals are recognized as expenses in the periods in which they are incurred. Operating lease payments are recognized as an expense on a straight-line basis over the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. Contingent rentals arising under operating leases are recognized as an expense in the period in which they are incurred. In the event that lease incentives are received to enter into operating leases, such incentives are recognized as a liability. The aggregate benefit of incentives is recognized as a reduction of rental expense on a straight-line basis, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. (iii) Determining whether an arrangement contains a lease At inception of an arrangement, the Company determines whether the arrangement is or contains a lease. At inception or on reassessment of an arrangement that contains a lease, the Company separates payments and other consideration required by the arrangement into those for the lease and those for other elements on the basis of their relative fair values. If the Company concludes for a finance lease that it is impracticable to separate the payments reliably, then an asset and a liability are recognized at an amount equal to the fair value of the underlying asset. |
Foreign currencies | Transactions in foreign currencies are translated to the respective functional currencies of the Company entities at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated to the functional currency using the reporting date’s exchange rate. Non-monetary Exchange differences are recognized in profit or loss in the period in which they arise except for: • Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings; • Exchange differences on transactions entered into in order to hedge certain foreign currency risks (refer to note 3.(25) Derivative financial instruments, including hedge accounting); and • Exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned nor likely to occur (therefore forming part of the net investment in the foreign operation), which are recognized initially in other comprehensive income and reclassified from equity to income or loss on disposal or partial disposal of the net investment. For the purpose of presenting financial statements, the assets and liabilities of the Company’s foreign operations are expressed in Korean won using exchange rates prevailing at the end of the reporting period. Income and expense items are translated at the average exchange rates for the period, unless exchange rates fluctuated significantly during that period, in which case the exchange rates at the dates of the transactions are used. Exchange differences arising, if any, are recognized in other comprehensive income and accumulated in equity. When a foreign operation is disposed of, the relevant amount in the translation is transferred to profit or loss as part of the gain or loss on disposal. |
Borrowing costs | The Company capitalizes borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. Other borrowing costs are recognized in expense as incurred. A qualifying asset is an asset that requires a substantial period of time to get ready for its intended use or sale. Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in income or loss in the period in which they are incurred. |
Government grants | Government grants and income related to transfer of assets from customers Government grants are not recognized unless there is reasonable assurance that the Company will comply with the grant’s conditions and that the grant will be received. Benefit from a government loan at a below-market interest rate is treated as a government grant, measured as the difference between proceeds received and the fair value of the loan based on prevailing market interest rates. (i) If the Company received grants related to assets Government grants whose primary condition is that the Company purchase, construct or otherwise acquire long-term assets are deducted in calculating the carrying amount of the asset. The grant is recognized in profit or loss over the life of a depreciable asset as a reduced depreciation expense. (ii) If the Company received grants related to income Government grants which are intended to compensate the Company for expenses incurred are recognized as other income (government grants) in profit or loss over the periods in which the Company recognizes the related costs as expenses. The Company recovers a substantial amount of the cost related to its electric power distribution facilities from customers through the transfer of assets, while the remaining portion is recovered through electricity sales from such customers in the future. As such, the Company believes there exists a continued service obligation to the customers in accordance with IFRIC 18 ‘Transfer of Assets from Customers’ when the Company receives an item of property, equipment, or cash for constructing or acquiring an item of property or equipment, in exchange for supplying electricity to customers. The Company defers the amounts received, which are subsequently recognized as other income on a straight-line basis over the estimated service period which does not exceed the transferred asset’s useful life. |
Employee benefits | When an employee has rendered service to the Company during a period, the Company recognizes the contribution payable to a defined contribution plan in exchange for that service as a liability (accrued expense). For defined benefit pension plans and other post-employment benefits, the net periodic pension expense is actuarially determined by “Pension Actuarial System” developed by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. However, if there is not a deep market, market yields on government bonds are used. Net defined benefit liability’s measurement is composed of actuarial gains and losses, return on plan assets excluding net interest on net defined benefit liability, and any change in the effect of the asset ceiling, excluding net interest, which are immediately recognized in other comprehensive income. The actuarial gains or losses recognized in other comprehensive income which will not be reclassified into net profit or loss for later periods are immediately recognized in retained earnings. Past service cost will be recognized as expenses upon the earlier of the date of change or reduction to the plan, or the date of recognizing termination benefits. The retirement benefit obligation recognized in the statement of financial position represents the present value of the defined benefit obligation as adjusted for unrecognized actuarial gains and losses and unrecognized past service cost, and as reduced by the fair value of plan assets. Any asset resulting from this calculation is limited to unrecognized actuarial losses and past service cost, plus the present value of available refunds and reductions in future contributions to the plan. |
Income taxes | Income tax expense comprises current and deferred tax. Current tax and deferred tax are recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in other comprehensive income. (i) Current tax Current tax is the expected tax payable or receivable on the taxable profit or loss for the year, using tax rates enacted or substantively enacted at the end of the reporting period and any adjustment to tax payable in respect of previous years. The taxable profit is different from the accounting profit for the period since the taxable profit is calculated excluding the temporary differences, which will be taxable or deductible in determining taxable profit (tax loss) of future periods, and non-taxable non-deductible (ii) Deferred tax Deferred tax is recognized, using the asset-liability method, in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. A deferred tax liability is recognized for all taxable temporary differences. A deferred tax asset is recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which they can be utilized. However, deferred tax is not recognized for the following temporary differences: taxable temporary differences arising on the initial recognition of goodwill, or the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting profit or loss nor taxable income. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets or deferred tax liabilities on investment properties measured at fair value, unless any contrary evidence exists, are measured using the assumption that the carrying amount of the property will be recovered entirely through sale. The Company recognizes a deferred tax liability for all taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint ventures, except to the extent that the Company is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The Company recognizes a deferred tax asset for all deductible temporary differences arising from investments in subsidiaries and associates, to the extent that it is probable that the temporary difference will reverse in the foreseeable future and taxable profit will be available against which the temporary difference can be utilized. The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and reduces the carrying amount to the extent that it is no longer probable that sufficient taxable profit will be available to allow the benefit of part or all of that deferred tax asset to be utilized. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by the end of the reporting period. The measurement of deferred tax liabilities and deferred tax assets reflects the tax consequences that would follow from the manner in which the Company expects, at the end of the reporting period to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset only if there is a legally enforceable right to offset the related current tax liabilities and assets, and they relate to income taxes levied by the same tax authority and they intend to settle current tax liabilities and assets on a net basis. (iii) Current and deferred tax for the year Current and deferred tax are recognized in income or loss, except when they relate to items that are recognized in other comprehensive income or directly in equity, in which case, the current and deferred tax are also recognized in other comprehensive income or directly in equity respectively. Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination. |
Property, plant and equipment | Property, plant and equipment are initially measured at cost and after initial recognition, are carried at cost less accumulated depreciation and accumulated impairment losses. The cost of property, plant and equipment includes expenditures arising directly from the construction or acquisition of the asset, any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management and the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located. Subsequent costs are recognized in the carrying amount of property, plant and equipment at cost or, if appropriate, as separate items if it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day Property, plant and equipment, except for land, are depreciated on a straight-line basis over estimated useful lives that appropriately reflect the pattern in which the asset’s future economic benefits are expected to be consumed. For loaded nuclear fuel related to long-term raw materials and spent nuclear fuels related to asset retirement costs, the Company uses the production method to measure and recognizes as expense the economic benefits of the assets. The estimated useful lives of the Company’s property, plant and equipment are as follows: Useful lives (years) Buildings 8 ~ 40 Structures 8 ~ 50 Machinery 2 ~ 32 Vehicles 3 ~ 8 Loaded heavy water 30 Asset retirement costs 18, 30, 40, 60 Finance lease assets 6 ~ 32 Ships 9 Others 4 ~ 15 A component that is significant compared to the total cost of property, plant and equipment is depreciated over its separate useful life. Depreciation methods, residual values and useful lives of property, plant and equipment are reviewed at the end of each reporting period and if change is deemed appropriate, it is treated as a change in accounting estimate. As a result of such annual review, useful lives of certain machinery were changed during 2016. Depreciation expenses increased by ₩160,985 million for the year ended December 31, 2016. Depreciation expenses increased by ₩160,985 million and ₩130,514 million for the years ended December 31, 2016 and 2017, respectively. Depreciation expenses are expected to increase by ₩91,197 million for the year ending December 31, 2018, and to decrease by ₩382,696 million for the years after December 31, 2018. Property, plant and equipment are derecognized on disposal, or when no future economic benefits are expected from its use or disposal. Gains or losses arising from derecognition of a property, plant and equipment, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in income or loss when the asset is derecognized. |
Investment property | Property held for the purpose of earning rentals or benefiting from capital appreciation is classified as investment property. Investment property is initially measured at its cost. Transaction costs are included in the initial measurement. Subsequently, investment property is carried at depreciated cost less any accumulated impairment losses. Subsequent costs are recognized in the carrying amount of investment property at cost or, if appropriate, as separate items if it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day Investment property except for land, are depreciated on a straight-line basis over 8 ~ 40 years as estimated useful lives. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis. An investment property is derecognized upon disposal or when the investment property is permanently withdrawn from use and no future economic benefits are expected from the disposal. Any gain or loss arising on derecognition of the property (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in income or loss in the period in which the property is derecognized. |
Intangible assets | Intangible assets (i) Intangible assets acquired separately Intangible assets with finite useful lives that are acquired separately are carried at cost less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over their estimated useful lives. The estimated useful life and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis. Intangible assets with indefinite useful lives that are acquired separately are carried at cost less accumulated impairment losses. (ii) Research and development Expenditure on research activities is recognized as an expense in the period in which it is incurred. An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognized if, and only if, all of the following have been demonstrated: • The technical feasibility of completing the intangible asset so that it will be available for use or sale; • The intention to complete the intangible asset and use or sell it; • The ability to use or sell the intangible asset; • How the intangible asset will generate probable future economic benefits; • The availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and • The ability to measure reliably the expenditure attributable to the intangible asset during its development. The amount initially recognized for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. When the development expenditure does not meet the criteria listed above, an internally-generated intangible asset cannot be recognized and the expenditure is recognized in income or loss in the period in which it is incurred. Internally-generated intangible assets are reported at cost less accumulated amortization and accumulated impairment losses. The estimated useful lives and amortization methods of the Company’s intangible assets with finite useful lives are as follows: Useful lives (years) Amortization methods Usage rights for donated assets 10 ~ 20 Straight line Software 4, 5 Straight line Industrial rights 5, 10 Straight line Development expenses 5 Straight line Leasehold rights 10 Straight line Mining right — Unit of production Others 3 ~ 50 or Indefinite Straight line (iii) Intangible assets acquired in a business combination Intangible assets that are acquired in a business combination are recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. (iv) Derecognition of intangible assets An intangible asset is derecognized on disposal, or when no future economic benefits are expected from its use or disposal. Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset, and are recognized in income or loss when the asset is derecognized. |
Greenhouse gas emissions rights (allowances) and obligations | Greenhouse gas emissions rights (allowances) and obligations In connection with Enforcement of Allocation and Trading of Greenhouse Gas Emissions Allowances, the Company applies the following accounting policies for greenhouse gas emissions rights and obligations. (i) Greenhouse gas emissions rights Greenhouse gas emissions rights consist of the allowances received free of charge from the government and the ones purchased. The cost of the greenhouse gas emissions rights includes expenditures arising directly from the acquisition and any other costs incurred during normal course of the acquisition. Greenhouse gas emissions rights are held by the Company to fulfill the legal obligation and recorded as intangible assets. To the extent that the portion to be submitted to the government within one year from the end of reporting period, the greenhouse gas emissions rights are classified as current assets. Greenhouse gas emissions rights recorded as intangible assets are initially measured at cost and substantially remeasured at cost less accumulated impairment losses. Greenhouse gas emissions rights are derecognized on submission to the government or when no future economic benefits are expected from its use or disposal. (ii) Greenhouse gas emissions obligations Greenhouse gas emissions obligations are the Company’s present legal obligation to submit the greenhouse gas emissions allowances to the government and recognized when an outflow of resources is probable and a reliable estimate can be made of the amount of the obligation. Greenhouse gas emissions obligations are measured as the sum of the carrying amount of the allocated rights that will be submitted to the government and the best estimate of expenditure required to settle the obligation at the end of the reporting period for any excess emission. |
Impairment of non-financial assets other than goodwill | non-financial At the end of each reporting period, the Company reviews the carrying amounts of its tangible and intangible assets with definite useful lives to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit to which the asset belongs. Where a reasonable and consistent basis of allocation can be identified, corporate assets are also allocated to individual cash-generating units, or otherwise they are allocated to the smallest group of cash-generating units for which a reasonable and consistent allocation basis can be identified. Intangible assets with indefinite useful lives and intangible assets not yet available for use are tested for impairment at least annually, and whenever there is an indication that the asset may be impaired. Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax If the recoverable amount of an asset (or a cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or the cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease. When an impairment loss subsequently reverses, the carrying amount of the asset (or a cash-generating unit) is increased to the revised estimate of its recoverable amount, to the extent the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase. |
Inventories | Inventories are measured at the lower of cost and net realizable value. Cost of inventories for inventories in transit are measured by using specific identification method. Cost of inventories, except for those in transit, are measured under the weighted average method and consists of the purchase price, cost of conversion and other costs incurred in bringing the inventories to their present location and condition. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expenses. The amount of any write-down of inventories to net realizable value and all losses of inventories are recognized as an expense in the period the write-down or loss occurs. The amount of any reversal of any write-down of inventories, arising from an increase in net realizable value, are recognized as a reduction in the amount of inventories recognized as an expense in the period in which the reversal occurs. |
Provisions | Provisions are recognized when the Company has a present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The risks and uncertainties that inevitably surround many events and circumstances are taken into account in reaching the best estimate of a provision. Where the effect of the time value of money is material, provisions are determined at the present value of the expected future cash flows. Where some or all of the expenditures required to settle a provision are expected to be reimbursed by another party, the reimbursement shall be recognized when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. The reimbursement shall be treated as a separate asset. Provisions are reviewed at the end of each reporting period and adjusted to reflect the current best estimates. If it is no longer probable that an outflow of resources embodying economic benefits will be required to settle the obligation, the provision is reversed. (i) Provision for employment benefits The Company determines the provision for employment benefits as the incentive payments based on the results of the individual performance evaluation or management assessment. (ii) Provision for decommissioning costs of nuclear power plants The Company records the fair value of estimated decommissioning costs as a liability in the period in which the Company incurs a legal obligation associated with retirement of long-lived assets that result from acquisition, construction, development and/or normal use of the assets. Accretion expense consists of period-to-period (iii) Provision for disposal of spent nuclear fuel Under the Radioactive Waste Management Act, the Company is levied to pay the spent nuclear fuel fund for the management of spent nuclear fuel. The Company recognizes the provision of present value of the payments. (iv) Provision for low and intermediate radioactive wastes Under the Radioactive Waste Management Act, the Company recognizes the provision for the disposal of low and intermediate radioactive wastes in best estimate of the expenditure required to settle the present obligation. (v) Provision for Polychlorinated Biphenyls (“PCBs”) Under the regulation of Persistent Organic Pollutants Management Act, enacted in 2007, the Company is required to remove PCBs, a toxin, from the insulating oil of its transformers by 2025. As a result of the enactments, the Company is required to inspect the PCBs contents of transformers and dispose of PCBs in excess of safety standards under the legally settled procedures. The Company’s estimates and assumptions used to determine fair value can be affected by many factors, such as the estimated costs of inspection and disposal, inflation rate, discount rate, regulations and the general economy. (vi) Provisions for power plant regional support program Power plant regional support programs consist of scholarship programs to local students, local economy support programs, local culture support programs, environment development programs, and local welfare programs. The Company recognizes the provision in relation to power plant regional support program. (vii) Provisions for transmission and transformation facilities-neighboring areas support program The Company has present obligation to conduct transmission and transformation facilities-neighboring areas support program under Act on assistance to transmission and transformation facilities-neighboring areas. The Company recognizes the provision of estimated amount to fulfill the obligation. (viii) Renewable Portfolio Standard (“RPS”) provisions RPS program is required to generate a specified percentage of total electricity to be generated in the form of renewable energy and provisions are recognized for the governmental regulations to require the production of energies from renewable energy sources such as solar, wind and biomass. |
Non-derivative financial assets | The Company recognizes and measures non-derivative held-to-maturity available-for-sale non-derivative A regular way purchase or sale of financial assets shall be recognized and derecognized, as applicable, using trade date accounting or settlement date accounting. A regular way purchase or sale is a purchase or sale of a financial asset under a contract whose terms require delivery of the asset within the time frame established generally by regulation or convention in the marketplace concerned. (i) Effective interest method The effective interest method is a method of calculating the amortized cost of a debt instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash receipts (including all fees and points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the debt instrument, or, where appropriate, a shorter period, to the net carrying amount on initial recognition. Income is recognized on an effective interest basis for debt instruments other than those financial assets classified as financial assets at fair value through profit or loss. (ii) Financial assets at fair value through profit or loss (FVTPL) A financial asset is classified as financial assets are classified at fair value through profit or loss if it is held for trading or is designated as such upon initial recognition. Upon initial recognition, transaction costs are recognized in profit or loss when incurred. A financial assets its acquired principally for the purpose of selling it in the near term are classified as a short-term financial assets held for trading and also all the derivatives including an embedded derivate that is not designated and effective as a hedging instrument are classified at the short-term trading financial asset as well. Financial assets at fair value through profit or loss are measured at fair value, and changes therein are recognized in profit or loss. A financial asset is classified as held for trading if: • It has been acquired principally for the purpose of selling it in the near term; or • On initial recognition it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short term profit taking; or • It is derivative, including an embedded derivative that is not designated and effective as a hedging instrument. A financial asset other than a financial asset held for trading may be designated as at financial assets at fair value through profit or loss upon initial recognition if: • Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or • The financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its’ performance is evaluated on a fair value basis in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or • It forms a part of a contract containing one or more embedded derivatives, and with IAS No. 39, Financial Instruments; Recognition and Measurement permits the entire combined contract (asset or liability) to be designated as at financial assets at fair value through profit or loss. Financial assets at fair value through profit or loss are stated at fair value, with any gains or losses arising on re-measurement (iii) Held-to-maturity A non-derivative held-to-maturity held-to-maturity (iv) Available-for-sale Available-for-sale non-derivative available-for-sale held-to-maturity Gains and losses arising from changes in fair value are recognized in other comprehensive income and accumulated in the valuation reserve. However, impairment losses, interest calculated using the effective interest method, and foreign exchange gains and losses on monetary assets are recognized in income or loss. Unquoted equity investments which are not traded in an active market, whose fair value cannot be measured reliably are carried at cost. When a financial asset is derecognized or impairment losses are recognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to profit or loss. Dividends on an available-for-sale The fair value of available-for-sale (v) Loans and receivables Loans and receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, loans and receivables are measured at amortized cost using the effective interest method except for loans and receivables of which the effect of discounting is immaterial. (vi) Impairment of financial assets Financial assets, other than those at financial assets at fair value through profit or loss, are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected. For listed and unlisted equity investments classified as available-for-sale For all other financial assets, objective evidence of impairment could include: • Significant financial difficulty of the issuer or counterparty; or • Breach of contract, such as a default or delinquency in interest or principal payments, or • It becoming probable that the borrower will enter bankruptcy or financial re-organization; • The disappearance of an active market for that financial asset because of financial difficulties. For certain categories of financial asset, such as trade receivables, assets that are assessed not to be impaired individually are, in addition, assessed for impairment on a collective basis. Objective evidence of impairment for a portfolio of receivables could include the Company’s past experience of collecting payments, an increase in the number of delayed payments in the portfolio past the average credit period and, as well as observable changes in national or local economic conditions that correlate with default on receivables. For financial assets recorded at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate. For financial assets carried at cost, the amount of the impairment loss is measured as the difference between the asset’s carrying amount and the present value of the estimated future cash flows discounted at the current market rate of return for a similar financial asset. Such impairment loss will not be reversed in subsequent periods. The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables, where the carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in income or loss. When an available-for-sale For financial assets measured at amortized cost, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized. In respect of available-for-sale available-for-sale (vii) De-recognition The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows on the financial asset in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred. Any interest in transferred financial assets that is created or retained by the Company is recognized as a separate asset or liability. If the Company retains substantially all the risks and rewards of ownership of the transferred financial assets, the Company continues to recognize the transferred financial assets and recognizes financial liabilities for the consideration received. On de-recognition On de-recognition |
Non-derivative financial liabilities and equity instruments issued by the Company | (i) Classification as debt or equity Debt and equity instruments are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangement. (ii) Equity instruments An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments issued by the Company are recognized at the proceeds received, net of direct issue costs. Repurchase of the Company’s own equity instruments is recognized and deducted directly in equity. No gain or loss is recognized in income or loss on the purchase, sale, issue or cancelation of the Company’s own equity instruments. (iii) Financial liabilities Financial liabilities are recognized when the Company becomes a party to the contractual provisions of the instruments. Financial liabilities are initially measured at fair value. Transaction cost that are directly attributable to the issue of financial liabilities are added to or deducted from the fair value of the financial liabilities, as appropriate, on initial recognition. Transaction cost directly attributable to acquisition of financial liabilities at fair value through profit or loss are recognized immediately in profit or loss. Financial liabilities are classified as either financial liabilities at fair value through profit or loss or other financial liabilities. (iv) Financial liabilities at fair value through profit or loss (FVTPL) Financial liabilities are classified as at financial liabilities at fair value through profit or loss when the financial liability is either held for trading or it is designated as financial liabilities at fair value through profit or loss. A financial liability is classified as held for trading if: • It has been acquired principally for the purpose of repurchasing it in the near term; or • On initial recognition it is part of a portfolio of identified financial instruments that the Company manages together and has a recent actual pattern of short-term profit-taking; or • It is a derivative that is not designated and effective as a hedging instrument. A financial liability other than a financial liability held for trading may be designated as at FVTPL upon initial recognition if: • Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or • The financial liability forms part of a Company of financial assets or financial liabilities or both, which is managed and its performance is evaluated on a fair value basis, in accordance with the Company’s documented risk management or investment strategy, and information about the grouping is provided internally on that basis; or • It forms part of a contract containing one or more embedded derivatives, and IAS 39 ‘Financial Instruments: Recognition and Measurement’, permits the entire combined contract (asset or liability) to be designated as at FVTPL. Financial liabilities at fair value through profit or loss are stated at fair value, with any gains or losses arising on re-measurement (v) Other financial liabilities Other financial liabilities, including borrowings, are initially measured at fair value, net of transaction costs. Other financial liabilities are subsequently measured at amortized cost using the effective interest method, with interest expense recognized on an effective yield basis. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or (where appropriate) a shorter period, to the net carrying amount on initial recognition. (vi) Financial guarantee contract liabilities Financial guarantee contract liabilities are initially measured at their fair values and, if not designated as at FVTPL, are subsequently measured at the higher of: (a) the amount of the obligation under the contract, as determined in accordance with IAS 37 ‘Provisions, Contingent Liabilities and Contingent Assets; or (b) the amount initially recognized less, cumulative amortization recognized in accordance with IAS 18 ‘Revenue’. (vii) De-recognition The Company derecognizes financial liabilities when, and only when, the Company’s obligations are discharged, canceled or they expire. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable is recognized in income or loss. |
Service Concession Arrangements | Service Concession Arrangements The Company recognizes revenues from construction services and operating services related to service concession arrangements in accordance with IAS 11 ’Construction Contracts’ and IAS 18 ‘Revenue’, respectively. If the Company performs more than one service under a single contract or arrangement, consideration received or receivable is allocated by reference to the relative fair values of the services delivered, when the amounts are separately identifiable. The Company recognizes a financial asset to the extent that it has an unconditional contractual right to receive cash or another financial asset for the construction services and an intangible asset to the extent that it receives a right (license) to charge users of the public service. Borrowing costs attributable to the arrangement are recognized as an expense in the period in which they are incurred unless the Company has a contractual right to receive an intangible asset (a right to charge users of the public service). In this case, borrowing costs attributable to the arrangement are capitalized during the construction phase of the arrangement. |
Derivative financial instruments, including hedge accounting | The Company enters into a variety of derivative financial instruments to manage its exposure to interest rate and foreign exchange rate risk, including foreign exchange forward contracts, interest rate swaps and cross currency swaps and others. Derivatives are initially recognized at fair value. Subsequent to initial recognition, derivatives are measured at fair value. The resulting gain or loss is recognized in income or loss immediately unless the derivative is designated and effective as a hedging instrument, in such case the timing of the recognition in income or loss depends on the nature of the hedge relationship. A derivative with a positive fair value is recognized as a financial asset; a derivative with a negative fair value is recognized as a financial liability. A derivative is presented as a non-current non-current (i) Separable embedded derivatives Derivatives embedded in other financial instruments or other host contracts are treated as separate derivatives when their risks and characteristics are not closely related to those of the host contracts and when the host contracts are not measured at FVTPL. An embedded derivative is presented as a non-current non-current (ii) Hedge accounting The Company designates certain hedging instruments, which include derivatives, embedded derivatives and non-derivatives At the inception of the hedge relationship, the entity documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item. (iii) Fair value hedges Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in income or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The changes in the fair value of the hedging instrument and the change in the hedged item attributable to the hedged risk relating to the hedged items are recognized in the consolidated statements of comprehensive income. Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. The fair value adjustment to the carrying amount of the hedged item arising from the hedged risk is amortized as income or loss as of that date. (iv) Cash flow hedges The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in income or loss, and is included in the ‘finance income and expense’. Amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to income or loss in the periods when the hedged item is recognized in income or loss, in the same line of the consolidated statement of comprehensive income as the recognized hedged item. However, when the forecast transaction that is hedged results in the recognition of a non-financial non-financial non-financial non-financial Hedge accounting is discontinued when the Company revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or it no longer qualifies for hedge accounting. Any gain or loss accumulated in equity at that time remains in equity and is recognized when the forecast transaction is ultimately recognized in income or loss. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in income or loss. |

Segment, Geographic and Other Information [Abstract] | |
Segment determination and explanation of the measurements | The Company’s operating segments are its business components that generate discrete financial information that is reported to and regularly reviewed by the Company’s the chief operating decision maker, the Chief Executive Officer, for the purpose of resource allocation and assessment of segment performance. The Company’s reportable segments are ‘Transmission and distribution’, ‘Electric power generation (Nuclear)’, ‘Electric power generation (Non-nuclear)’, Segment operating profit (loss) is determined the same way that consolidated operating profit is determined under IFRS without any adjustment for corporate allocations. The accounting policies used by each segment are consistent with the accounting policies used in the preparation of the consolidated financial statements. Segment assets and liabilities are determined based on separate financial statements of the entities instead of on a consolidated basis. There are various transactions between the reportable segments, including sales of property, plant and equipment and so on, that are conducted on an arms-length basis at market prices that would be applicable to an independent third-party. For subsidiaries which are in a different segment from that of its immediate parent company, their carrying amount in separate financial statements is eliminated in the consolidating adjustments in the tables below. In addition, consolidation adjustments in the table below include adjustments of the amount of investment in associates and joint ventures from the cost basis amount reflected in segment assets to that determined using equity method in the consolidated financial statements. |
