General/Organization and Operations | General Berkshire Hathaway Energy Company (" BHE ") is a holding company that owns a highly diversified portfolio of locally managed businesses principally engaged in the energy industry (collectively with its subsidiaries, the "Company") and is a consolidated subsidiary of Berkshire Hathaway Inc. (" Berkshire Hathaway "). The Company's operations are organized as eight business segments: PacifiCorp , MidAmerican Funding, LLC (" MidAmerican Funding ") (which primarily consists of MidAmerican Energy Company (" MidAmerican Energy ")), NV Energy, Inc. (" NV Energy ") (which primarily consists of Nevada Power Company (" Nevada Power ") and Sierra Pacific Power Company (" Sierra Pacific ")), Northern Powergrid Holdings Company (" Northern Powergrid ") (which primarily consists of Northern Powergrid (Northeast) Limited and Northern Powergrid (Yorkshire) plc ), BHE Pipeline Group (which primarily consists of Northern Natural Gas Company (" Northern Natural Gas ") and Kern River Gas Transmission Company (" Kern River ")), BHE Transmission (which consists of BHE Canada Holdings Corporation (" BHE Canada ") (which primarily consists of AltaLink, L.P. (" AltaLink ")) and BHE U.S. Transmission, LLC ), BHE Renewables (which primarily consists of BHE Renewables, LLC and CalEnergy Philippines ) and HomeServices of America, Inc. (collectively with its subsidiaries, " HomeServices "). The Company, through these locally managed and operated businesses, owns four utility companies in the United States serving customers in 11 states, two electricity distribution companies in Great Britain, two interstate natural gas pipeline companies in the United States, an electric transmission business in Canada, interests in electric transmission businesses in the United States, a renewable energy business primarily investing in wind, solar, geothermal and hydroelectric projects, the largest residential real estate brokerage firm in the United States and one of the largest residential real estate brokerage franchise networks in the United States. The unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Consolidated Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Consolidated Financial Statements as of June 30, 2020 and for the three- and six-month periods ended June 30, 2020 and 2019 . The results of operations for the three- and six-month periods ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year. The preparation of the unaudited Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Consolidated Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Consolidated Financial Statements. Note 2 of Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019 describes the most significant accounting policies used in the preparation of the unaudited Consolidated Financial Statements. There have been no significant changes in the Company's assumptions regarding significant accounting estimates and policies during the six-month period ended June 30, 2020 . Coronavirus Disease 2019 ("COVID-19") In March 2020, COVID-19 was declared a global pandemic and containment and mitigation measures were recommended worldwide, which has had an unprecedented impact on society in general and on worldwide economic conditions. COVID-19 has impacted many of the Company's customers ranging from high unemployment levels, an inability to pay bills and business closures or operating at reduced capacity levels. While COVID-19 has impacted the Company's financial results and operations through June 30, 2020, the impacts have not been material. However, more severe impacts may still occur that could adversely affect future financial results depending on the duration and extent of COVID-19. These impacts include, but are not limited to, lower operating revenue and higher bad debt expense. The duration and extent of COVID-19 and its future impact on the Company's businesses cannot be reasonably estimated at this time. Accordingly, significant estimates used in the preparation of the Company's unaudited Consolidated Financial Statements, including those associated with evaluations of certain long-lived assets, goodwill and other intangible assets for impairment, expected credit losses on amounts owed to the Company and potential regulatory deferral or recovery of certain costs may be subject to significant adjustments in future periods. |

The Consolidated Statements of Comprehensive Income have been omitted as net income materially equals comprehensive income for the three- and six-month periods ended June 30, 2020 and 2019 .

There have been no significant changes in PacifiCorp's assumptions regarding significant accounting estimates and policies during the six-month period ended June 30, 2020 . Coronavirus Disease 2019 ("COVID-19") In March 2020, COVID‑19 was declared a global pandemic and containment and mitigation measures were recommended worldwide, which has had an unprecedented impact on society in general and on economic conditions in the United States. COVID-19 has impacted many of PacifiCorp's customers ranging from high unemployment levels, an inability to pay bills and business closures or operating at reduced capacity levels. While COVID‑19 has impacted PacifiCorp's financial results and operations through June 30, 2020, the impacts have not been material. However, more severe impacts may still occur that could adversely affect future financial results depending on the duration and extent of COVID-19. These impacts include, but are not limited to, lower operating revenue from reductions in the consumption of electricity by retail utility customers, particularly in the commercial and industrial customer classes as the longer term impacts of COVID-19 and related customer and governmental responses remain uncertain, and higher bad debt expense resulting from a higher than average level of write-offs of uncollectible accounts associated with the suspension of disconnections across PacifiCorp's service territory and suspension of late payment fees in certain jurisdictions implemented to assist customers. Other impacts may include increased retirement plan contributions due to reductions in the market value of retirement plan assets. The duration and extent of COVID‑19 and its future impact on PacifiCorp's business cannot be reasonably estimated at this time. Accordingly, significant estimates used in the preparation of PacifiCorp's unaudited Consolidated Financial Statements, including those associated with evaluations of certain long-lived assets for impairment, expected credit losses on amounts owed to PacifiCorp and potential regulatory deferral or recovery of certain costs may be subject to significant adjustments in future periods. In March and April 2020, PacifiCorp filed applications requesting authorization to defer costs associated with COVID‑19 with the Utah Public Service Commission, the Oregon Public Utility Commission, the Wyoming Public Service Commission ("WPSC"), the Washington Utilities and Transportation Commission and the Idaho Public Utilities Commission ("IPUC"). In April 2020, as ordered by the California Public Utilities Commission, PacifiCorp filed to establish the COVID‑19 Pandemic Protections Memorandum Account. In April 2020, the WPSC approved PacifiCorp's application to defer costs associated with COVID‑19, subject to a public notice period, and required associated benefits arising from COVID‑19 to be offset against the deferred costs. During the public notice period, one party to the proceeding filed a petition for a rehearing of the matter. In July 2020, the IPUC approved PacifiCorp's application to defer costs associated with COVID‑19 and required associated benefits arising from COVID‑19 to be offset against the deferred costs. |

General/Organization and Operations | General Sierra Pacific Power Company ("Sierra Pacific"), is a wholly owned subsidiary of NV Energy, Inc. ("NV Energy"), a holding company that also owns Nevada Power Company ("Nevada Power") and certain other subsidiaries. Sierra Pacific is a United States regulated electric utility company serving retail customers, including residential, commercial and industrial customers and regulated retail natural gas customers primarily in northern Nevada. NV Energy is an indirect wholly owned subsidiary of Berkshire Hathaway Energy Company (" BHE "). BHE is a holding company based in Des Moines, Iowa that owns subsidiaries principally engaged in energy businesses. BHE is a consolidated subsidiary of Berkshire Hathaway Inc. (" Berkshire Hathaway "). The unaudited Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and the United States Securities and Exchange Commission's rules and regulations for Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements. Management believes the unaudited Financial Statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary for the fair presentation of the unaudited Financial Statements as of June 30, 2020 and for the three- and six-month periods ended June 30, 2020 and 2019 . The Statements of Comprehensive Income have been omitted as net income equals comprehensive income for the three- and six-month periods ended June 30, 2020 and 2019 . The results of operations for the three- and six-month periods ended June 30, 2020 are not necessarily indicative of the results to be expected for the full year. The preparation of the unaudited Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the unaudited Financial Statements and the reported amounts of revenue and expenses during the period. Actual results may differ from the estimates used in preparing the unaudited Financial Statements. Note 2 of Notes to Financial Statements included in Sierra Pacific's Annual Report on Form 10-K for the year ended December 31, 2019 describes the most significant accounting policies used in the preparation of the unaudited Financial Statements. There have been no significant changes in Sierra Pacific's assumptions regarding significant accounting estimates and policies during the six-month period ended June 30, 2020 . Coronavirus Disease 2019 ("COVID-19") In March 2020, COVID-19 was declared a global pandemic and containment and mitigation measures were recommended worldwide, which has had an unprecedented impact on society in general and on economic conditions in the United States. COVID-19 has impacted many of Sierra Pacific's customers ranging from high unemployment levels, an inability to pay bills and business closures or operating at reduced capacity levels. While COVID-19 has impacted Sierra Pacific's financial results and operations through June 30, 2020 , the impacts have not been material. However, more severe impacts may still occur that could adversely affect future financial results depending on the duration and extent of COVID-19. These impacts include, but are not limited to, lower operating revenue from reductions in the consumption of electricity by retail utility customers, particularly in the commercial, industrial and distribution only service customer classes as the longer term impacts of COVID-19 and related customer and governmental responses remain uncertain, and higher bad debt expense resulting from a higher than average level of write-offs of uncollectible accounts associated with the suspension of disconnections and late payment fees to assist customers. The duration and extent of COVID-19 and its future impact on Sierra Pacific's business cannot be reasonably estimated at this time. Accordingly, significant estimates used in the preparation of Sierra Pacific's unaudited Financial Statements, including those associated with evaluations of certain long-lived assets for impairment, expected credit losses on amounts owed to Sierra Pacific and potential regulatory recovery of certain costs may be subject to significant adjustments in future periods. In March 2020, the PUCN issued an emergency order for Sierra Pacific to establish a regulatory asset account related to the costs of maintaining service to customers affected by COVID-19 whose services would have been terminated or disconnected under normally-applicable terms of service. |

Business Combinations [Abstract] | |
Business Combination Disclosure [Text Block] | Business Acquisitions On July 3, 2020, BHE entered into a Purchase and Sale Agreement (the "Purchase Agreement") with Dominion Energy, Inc. ("DEI") and Dominion Energy Questar Corporation ("Dominion Questar," and together with DEI, the "Sellers") to purchase substantially all of the natural gas transmission and storage business of DEI and Dominion Questar (the "Transaction"). As part of the Transaction, BHE will acquire 100% of Dominion Energy Transmission, Inc., Dominion Energy Carolina Gas Transmission, LLC and Dominion Energy Questar Pipeline, LLC; 50% of Iroquois Gas Transmission System L.P.; and a 25% economic interest in Dominion Energy Cove Point LNG, LP ("Cove Point"), consisting of 100% of the general partnership interest and 25% of the total limited partnership interests. BHE will be the operator of Cove Point after the Transaction. The assets to be acquired include over 7,700 miles of natural gas transmission lines, with approximately 20.8 billion cubic feet ("Bcf") per day of transportation capacity and 900 Bcf of operated natural gas storage with 364 Bcf of company-owned working storage capacity, and a liquefied natural gas ("LNG") export, import and storage facility, with LNG storage of 14.6 Bcf. The Transaction is valued at approximately $9.7 billion , consisting of a cash purchase price of approximately $4.0 billion , subject to adjustment for cash and indebtedness as of the closing, and the assumption of approximately $5.7 billion of existing indebtedness for borrowed money. BHE expects to fund the purchase price, net of cash acquired, with capital from its shareholders. The consummation of the transactions contemplated by the Purchase Agreement is subject to customary closing conditions, including without limitation (i) the expiration or termination of any applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended ("HSR Approval"), (ii) the approval by the Department of Energy (the "DOE") with respect to a change of control of Cove Point, which holds certain foreign LNG import and export authorizations subject to the DOE's jurisdiction; and (iii) the approval by the Federal Communications Commission ("FCC") with respect to the transfer of certain FCC licenses. The Transaction is expected to close in the fourth quarter of 2020, subject to satisfaction of the foregoing conditions, among other things. The Purchase Agreement provides that if HSR Approval has not been obtained on or before 75 days following execution of the Purchase Agreement, so long as they are not in material breach of any of their representations, warranties, covenants or other agreements under the Purchase Agreement, the Sellers may exclude from the sale certain entities that own and operate natural gas pipelines in the Western United States (such termination with respect to these certain entities, a "Q-Pipe Termination"). In the event of a Q-Pipe Termination, the Sellers will complete an internal reorganization that will exclude these certain entities from the transactions contemplated by the Purchase Agreement and the cash purchase price will be reduced as set forth in the Purchase Agreement. |

Regulatory Matters | Regulatory Matters Deferred Energy Nevada statutes permit regulated utilities to adopt deferred energy accounting procedures. The intent of these procedures is to ease the effect on customers of fluctuations in the cost of purchased natural gas, fuel and electricity and are subject to annual prudency review by the PUCN. Under deferred energy accounting, to the extent actual fuel and purchased power costs exceed fuel and purchased power costs recoverable through current rates that excess is not recorded as a current expense on the Consolidated Statements of Operations but rather is deferred and recorded as a regulatory asset on the Consolidated Balance Sheets. Conversely, a regulatory liability is recorded to the extent fuel and purchased power costs recoverable through current rates exceed actual fuel and purchased power costs. These excess amounts are reflected in quarterly adjustments to rates and recorded as cost of fuel and energy in future time periods. 2017 Tax Reform In February 2018, Nevada Power made a filing with the PUCN proposing a tax rate reduction rider for the lower annual income tax expense anticipated to result from 2017 Tax Reform for 2018 and beyond. In March 2018, the PUCN issued an order approving the rate reduction proposed by Nevada Power . The new rates were effective April 1, 2018. The order extended the procedural schedule to allow parties additional discovery relevant to 2017 Tax Reform and a hearing was held in July 2018. In September 2018, the PUCN issued an order directing Nevada Power to record the amortization of any excess protected accumulated deferred income tax arising from the 2017 Tax Reform as a regulatory liability effective January 1, 2018. Subsequently, Nevada Power filed a petition for reconsideration relating to the amortization of protected excess accumulated deferred income tax balances resulting from the 2017 Tax Reform. In November 2018, the PUCN issued an order granting reconsideration and reaffirming the September 2018 order. In December 2018, Nevada Power filed a petition for judicial review. The judicial review occurred in January 2020 and the district court issued an order in March 2020 denying the petition and affirming the PUCN's order. In May 2020, Nevada Power filed a notice of appeal to the Nevada Supreme Court of the district court's order. Natural Disaster Protection Plan In May 2019, Senate Bill 329 ("SB 329"), Natural Disaster Mitigation Measures, was signed into law, which requires Nevada Power to submit a natural disaster protection plan to the PUCN. The PUCN adopted natural disaster protection plan regulations in January 2020, that require Nevada Power to file their natural disaster protection plan for approval on or before March 1 of every third year, with the first filing due on March 1, 2020. The regulations also require annual updates to be filed on or before September 1 of the second and third years of the plan. The plan must include procedures, protocols and other certain information as it relates to the efforts of Nevada Power to prevent or respond to a fire or other natural disaster. The expenditures incurred by Nevada Power in developing and implementing the natural disaster protection plan are required to be held in a regulatory asset account, with Nevada Power filing an application for recovery on or before March 1 of each year. Nevada Power submitted their initial natural disaster protection plan to the PUCN and filed their first application seeking recovery of 2019 expenditures in February 2020. In June 2020, a hearing was held and an order is expected in late August 2020. |

These excess amounts are reflected in quarterly adjustments to rates and recorded as cost of fuel and energy in future time periods. Regulatory Rate Review In June 2019, Sierra Pacific filed an electric regulatory rate review with the PUCN. The filing supported an annual revenue increase of $5 million but requested an annual revenue reduction of $5 million . In September 2019, Sierra Pacific filed an all-party settlement for the electric regulatory rate review. The settlement resolved all cost of capital and revenue requirement issues and provided for an annual revenue reduction of $5 million and required Sierra Pacific to share 50% of regulatory earnings above 9.7% with its customers. The rate design portion of the regulatory rate review was not a part of the settlement and a hearing on rate design was held in November 2019. In December 2019, the PUCN issued an order approving the stipulation but made some adjustments to the methodology for the weather normalization component of historical sales in rates, which resulted in an additional annual revenue reduction of $3 million . The new rates were effective January 1, 2020. In January 2020, Sierra Pacific filed a petition for rehearing challenging the PUCN's adjustments to the weather normalization methodology. In February 2020, the PUCN issued an order granting the petition for rehearing. In April 2020, the PUCN issued a final order approving a weather normalization methodology that changed the additional annual revenue reduction from $3 million to $2 million with an effective date of January 1, 2020. 2017 Tax Reform In February 2018, Sierra Pacific made a filing with the PUCN proposing a tax rate reduction rider for the lower annual income tax expense anticipated to result from 2017 Tax Reform for 2018 and beyond.

Derivative [Line Items] | |
Risk Management and Hedging Activities | Risk Management and Hedging Activities PacifiCorp is exposed to the impact of market fluctuations in commodity prices and interest rates. PacifiCorp is principally exposed to electricity, natural gas, coal and fuel oil commodity price risk as it has an obligation to serve retail customer load in its regulated service territories. PacifiCorp's load and generating facilities represent substantial underlying commodity positions. Exposures to commodity prices consist mainly of variations in the price of fuel required to generate electricity and wholesale electricity that is purchased and sold. Commodity prices are subject to wide price swings as supply and demand are impacted by, among many other unpredictable items, weather, market liquidity, geopolitical factors, generating facility availability, customer usage, storage, and transmission and transportation constraints. Interest rate risk exists on variable-rate debt and future debt issuances. PacifiCorp does not engage in a material amount of proprietary trading activities. PacifiCorp has established a risk management process that is designed to identify, manage and report each of the various types of risk involved in its business. To mitigate a portion of its commodity price risk, PacifiCorp uses commodity derivative contracts, which may include forwards, options, swaps and other agreements, to effectively secure future supply or sell future production generally at fixed prices. PacifiCorp manages its interest rate risk by limiting its exposure to variable interest rates primarily through the issuance of fixed-rate long-term debt and by monitoring market changes in interest rates. Additionally, PacifiCorp may from time to time enter into interest rate derivative contracts, such as interest rate swaps or locks, to mitigate PacifiCorp's exposure to interest rate risk. No interest rate derivatives were in place during the periods presented. PacifiCorp does not hedge all of its commodity price and interest rate risks, thereby exposing the unhedged portion to changes in market prices. There have been no significant changes in PacifiCorp's accounting policies related to derivatives. Refer to Note 8 for additional information on derivative contracts. The following table, which reflects master netting arrangements and excludes contracts that have been designated as normal under the normal purchases or normal sales exception afforded by GAAP, summarizes the fair value of PacifiCorp's derivative contracts, on a gross basis, and reconciles those amounts to the amounts presented on a net basis on the Consolidated Balance Sheets (in millions): Other Other Other Current Other Current Long-term Assets Assets Liabilities Liabilities Total As of June 30, 2020 Not designated as hedging contracts (1) : Commodity assets $ 9 $ 7 $ 6 $ — $ 22 Commodity liabilities (4 ) — (44 ) (42 ) (90 ) Total 5 7 (38 ) (42 ) (68 ) Total derivatives 5 7 (38 ) (42 ) (68 ) Cash collateral receivable — — 19 21 40 Total derivatives - net basis $ 5 $ 7 $ (19 ) $ (21 ) $ (28 ) As of December 31, 2019 Not designated as hedging contracts (1) : Commodity assets $ 15 $ 2 $ 4 $ — $ 21 Commodity liabilities (3 ) — (31 ) (50 ) (84 ) Total 12 2 (27 ) (50 ) (63 ) Total derivatives 12 2 (27 ) (50 ) (63 ) Cash collateral receivable — — 20 27 47 Total derivatives - net basis $ 12 $ 2 $ (7 ) $ (23 ) $ (16 ) (1) PacifiCorp's commodity derivatives are generally included in rates and as of June 30, 2020 and December 31, 2019 , a regulatory asset of $68 million and $62 million , respectively, was recorded related to the net derivative liability of $68 million and $63 million , respectively.

Credit risk may be concentrated to the extent PacifiCorp's counterparties have similar economic, industry or other characteristics and due to direct or indirect relationships among the counterparties. Before entering into a transaction, PacifiCorp analyzes the financial condition of each significant wholesale counterparty, establishes limits on the amount of unsecured credit to be extended to each counterparty and evaluates the appropriateness of unsecured credit limits on an ongoing basis. To further mitigate wholesale counterparty credit risk, PacifiCorp enters into netting and collateral arrangements that may include margining and cross-product netting agreements and obtains third-party guarantees, letters of credit and cash deposits. If required, PacifiCorp exercises rights under these arrangements, including calling on the counterparty's credit support arrangement. Collateral and Contingent Features In accordance with industry practice, certain wholesale agreements, including derivative contracts, contain credit support provisions that in part base certain collateral requirements on credit ratings for senior unsecured debt as reported by one or more of the three recognized credit rating agencies. These derivative contracts may either specifically provide bilateral rights to demand cash or other security if credit exposures on a net basis exceed specified rating-dependent threshold levels ("credit-risk-related contingent features") or provide the right for counterparties to demand "adequate assurance," or in some cases terminate the contract, in the event of a material adverse change in PacifiCorp's creditworthiness. These rights can vary by contract and by counterparty. As of June 30, 2020 , PacifiCorp's credit ratings for its senior secured debt and its issuer credit ratings for senior unsecured debt by Moody's Investor Service and Standard & Poor's Rating Services were investment grade. The aggregate fair value of PacifiCorp's derivative contracts in liability positions with specific credit-risk-related contingent features totaled $84 million and $80 million as of June 30, 2020 and December 31, 2019 , respectively, for which PacifiCorp had posted collateral of $40 million and $47 million , respectively, in the form of cash deposits. If all credit-risk-related contingent features for derivative contracts in liability positions had been triggered as of June 30, 2020 and December 31, 2019 , PacifiCorp would have been required to post $33 million and $27 million , respectively, of additional collateral. PacifiCorp's collateral requirements could fluctuate considerably due to market price volatility, changes in credit ratings, changes in legislation or regulation, or other factors. |

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items] | |
Fair Value Measurements | Fair Value Measurements The carrying value of the Company's cash, certain cash equivalents, receivables, payables, accrued liabilities and short-term borrowings approximates fair value because of the short-term maturity of these instruments. The Company has various financial assets and liabilities that are measured at fair value on the Consolidated Financial Statements using inputs from the three levels of the fair value hierarchy. A financial asset or liability classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows: • Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. • Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). • Level 3 — Unobservable inputs reflect the Company's judgments about the assumptions market participants would use in pricing the asset or liability since limited market data exists. The Company develops these inputs based on the best information available, including its own data. The following table presents the Company's financial assets and liabilities recognized on the Consolidated Balance Sheets and measured at fair value on a recurring basis (in millions): Input Levels for Fair Value Measurements Level 1 Level 2 Level 3 Other (1) Total As of June 30, 2020 Assets: Commodity derivatives $ 1 $ 54 $ 106 $ (27 ) $ 134 Interest rate derivatives — 1 78 — 79 Mortgage loans held for sale — 1,617 — — 1,617 Money market mutual funds (2) 1,357 — — — 1,357 Debt securities: United States government obligations 176 — — — 176 International government obligations — 4 — — 4 Corporate obligations — 73 — — 73 Municipal obligations — 3 — — 3 Agency, asset and mortgage-backed obligations — 5 — — 5 Equity securities: United States companies 336 — — — 336 International companies 1,745 — — — 1,745 Investment funds 194 — — — 194 $ 3,809 $ 1,757 $ 184 $ (27 ) $ 5,723 Liabilities: Commodity derivatives $ (2 ) $ (136 ) $ (62 ) $ 94 $ (106 ) Interest rate derivatives (5 ) (60 ) — — (65 ) $ (7 ) $ (196 ) $ (62 ) $ 94 $ (171 ) Input Levels for Fair Value Measurements Level 1 Level 2 Level 3 Other (1) Total As of December 31, 2019 Assets: Commodity derivatives $ — $ 45 $ 108 $ (24 ) $ 129 Interest rate derivatives — 2 14 — 16 Mortgage loans held for sale — 1,039 — — 1,039 Money market mutual funds (2) 824 — — — 824 Debt securities: United States government obligations 189 — — — 189 International government obligations — 4 — — 4 Corporate obligations — 58 — — 58 Municipal obligations — 1 — — 1 Agency, asset and mortgage-backed obligations — 1 — — 1 Equity securities: United States companies 336 — — — 336 International companies 1,131 — — — 1,131 Investment funds 169 — — — 169 $ 2,649 $ 1,150 $ 122 $ (24 ) $ 3,897 Liabilities: Commodity derivatives $ (4 ) $ (143 ) $ (11 ) $ 103 $ (55 ) Interest rate derivatives (2 ) (19 ) — — (21 ) $ (6 ) $ (162 ) $ (11 ) $ 103 $ (76 ) (1) Represents netting under master netting arrangements and a net cash collateral receivable of $67 million and $79 million as of June 30, 2020 and December 31, 2019 , respectively. (2) Amounts are included in cash and cash equivalents; other current assets; and noncurrent investments and restricted cash and investments on the Consolidated Balance Sheets. The fair value of these money market mutual funds approximates cost. Derivative contracts are recorded on the Consolidated Balance Sheets as either assets or liabilities and are stated at estimated fair value unless they are designated as normal purchases or normal sales and qualify for the exception afforded by GAAP. When available, the fair value of derivative contracts is estimated using unadjusted quoted prices for identical contracts in the market in which the Company transacts. When quoted prices for identical contracts are not available, the Company uses forward price curves. Forward price curves represent the Company's estimates of the prices at which a buyer or seller could contract today for delivery or settlement at future dates. The Company bases its forward price curves upon market price quotations, when available, or internally developed and commercial models, with internal and external fundamental data inputs. Market price quotations are obtained from independent brokers, exchanges, direct communication with market participants and actual transactions executed by the Company. Market price quotations are generally readily obtainable for the applicable term of the Company's outstanding derivative contracts; therefore, the Company's forward price curves reflect observable market quotes. Market price quotations for certain electricity and natural gas trading hubs are not as readily obtainable due to the length of the contract. Given that limited market data exists for these contracts, as well as for those contracts that are not actively traded, the Company uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The estimated fair value of these derivative contracts is a function of underlying forward commodity prices, interest rates, currency rates, related volatility, counterparty creditworthiness and duration of contracts. The Company's mortgage loans held for sale are valued based on independent quoted market prices, where available, or the prices of other mortgage whole loans with similar characteristics. As necessary, these prices are adjusted for typical securitization activities, including servicing value, portfolio composition, market conditions and liquidity. The Company's investments in money market mutual funds and debt and equity securities are stated at fair value. When available, a readily observable quoted market price or net asset value of an identical security in an active market is used to record the fair value. In the absence of a quoted market price or net asset value of an identical security, the fair value is determined using pricing models or net asset values based on observable market inputs and quoted market prices of securities with similar characteristics.

The carrying value of the Company's variable-rate long-term debt approximates fair value because of the frequent repricing of these instruments at market rates.

Given that limited market data exists for these contracts, Nevada Power uses forward price curves derived from internal models based on perceived pricing relationships to major trading hubs that are based on unobservable inputs. The model incorporates a mid-market pricing convention (the mid‑point price between bid and ask prices) as a practical expedient for valuing its assets and liabilities measured and reported at fair value. The determination of the fair value for derivative contracts not only includes counterparty risk, but also the impact of Nevada Power's nonperformance risk on its liabilities, which as of June 30, 2020 and December 31, 2019 , had an immaterial impact to the fair value of its derivative contracts. As such, Nevada Power considers its derivative contracts to be valued using Level 3 inputs. Nevada Power's investments in money market mutual funds and equity securities are stated at fair value.

Commitments and Contingencies | Commitments and Contingencies Construction Commitments During the six-month period ended June 30, 2020 , MidAmerican Energy entered into firm construction commitments totaling $269 million for the remainder of 2020 through 2021 related to the construction of wind-powered generating facilities in Iowa. Easements During the six-month period ended June 30, 2020 , MidAmerican Energy entered into non-cancelable easements with minimum payment commitments totaling $98 million through 2060 for land in Iowa on which some of its wind-powered generating facilities will be located. Maintenance and Service Contracts During the six-month period ended June 30, 2020 , MidAmerican Energy entered into non-cancelable maintenance and service contracts related to wind-powered generating facilities with minimum payment commitments totaling $72 million through 2031 . BHE Renewables' Counterparty Risk On January 29, 2019, PG&E Corporation and Pacific Gas and Electric Company (the "PG&E Utility") (together "PG&E") filed voluntary petitions for relief under chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Northern District of California ("PG&E Bankruptcy Filing"). The Company owns 100% of Topaz Solar Farm LLC ("Topaz") and owns a 49% interest in Agua Caliente Solar, LLC ("Agua Caliente"). Topaz is a 550 -MW solar photovoltaic electric power generating facility located in California. Topaz sells 100% of its energy, capacity and renewable energy credits ("RECs") generated from the facility to PG&E Utility under a 25-year wholesale power purchase agreement ("PPA") that is in effect until October 2039. Agua Caliente is a 290 -MW solar photovoltaic electric power generating facility located in Arizona. Agua Caliente sells 100% of its energy, capacity and RECs generated from the facility to PG&E Utility under a 25-year wholesale PPA that is in effect until June 2039. PG&E paid in full all amounts invoiced to date for post-petition energy deliveries for both Topaz and Agua Caliente as well as for the power delivered from January 1 through January 28, 2019. The PG&E Bankruptcy Filing was an event of default under the Topaz PPA ("PPA Default"); however, the Company maintained that, in light of the current facts and circumstances, the PPA Default could not reasonably be expected to result in a material adverse effect under the Topaz indenture and, therefore, no default had occurred under the Topaz indenture. On July 1, 2020, PG&E announced it had emerged from bankruptcy, successfully completing its restructuring process and implementing PG&E's Plan of Reorganization (the "Plan") that was confirmed by the United States Bankruptcy Court on June 20, 2020. The Company believes that no impairment exists and that current debt obligations will be met, as PG&E's emergence from bankruptcy has cured the PPA Default and PG&E's Plan includes the assumption of both the Topaz and Agua Caliente PPAs. The Company also expects to begin receiving distributions from Topaz and Agua Caliente in the second half of 2020 in accordance with the provisions of each respective debt agreement. Legal Matters The Company is party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. The Company does not believe that such normal and routine litigation will have a material impact on its consolidated financial results. The Company is also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines, penalties and other costs in substantial amounts and are described below. Environmental Laws and Regulations The Company is subject to federal, state, local and foreign laws and regulations regarding climate change, renewable portfolio standards, air and water quality, emissions performance standards, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact the Company's current and future operations. The Company believes it is in material compliance with all applicable laws and regulations. Hydroelectric Relicensing PacifiCorp is a party to the 2016 amended Klamath Hydroelectric Settlement Agreement ("KHSA"), which is intended to resolve disputes surrounding PacifiCorp's efforts to relicense the Klamath Hydroelectric Project. The KHSA does not guarantee dam removal. Instead, it establishes a process for PacifiCorp, the states of Oregon and California ("States") and other stakeholders to assess whether dam removal can occur consistent with the settlement's terms. For PacifiCorp, the key elements of the settlement include: (1) a contribution from PacifiCorp's Oregon and California customers capped at $200 million plus $250 million in California bond funds; (2) complete indemnification from harms associated with dam removal; (3) transfer of the Federal Energy Regulatory Commission ("FERC") license to a third-party dam removal entity, the Klamath River Renewal Corporation ("KRRC"), who would conduct dam removal; and (4) ability for PacifiCorp to operate the facilities for the benefit of customers until dam removal commences. In September 2016, the KRRC and PacifiCorp filed a joint application with the FERC to transfer the license for the four main-stem Klamath dams from PacifiCorp to the KRRC. The FERC approved partial transfer of the Klamath license in July 2020, subject to the condition that PacifiCorp remains co-licensee. Under the amended KHSA, PacifiCorp did not agree to remain co-licensee during the surrender and removal process given concerns about liability protections for PacifiCorp and its customers. The order does not immediately take effect, and PacifiCorp is evaluating the order in coordination with its settlement partners, including continued implementation of the agreement. Requests for rehearing are due on August 17, 2020 . The United States Court of Appeals for the District of Columbia Circuit issued a decision in the Hoopa Valley Tribe v. FERC litigation, in January 2019, finding that the states of California and Oregon have waived their Clean Water Act, Section 401, water quality certification authority over the Klamath hydroelectric project relicensing. This decision has the potential to limit the ability of the States to impose water quality conditions on new and relicensed projects. Environmental interests, supported by California, Oregon and other states, asked the court to rehear the case, which was denied. Subsequently, environmental groups, supported by numerous states, filed a petition for certiorari before the United States Supreme Court, which was denied on December 9, 2019, thereby allowing the circuit court opinion to stand as a final and unappealable decision. Guarantees The Company has entered into guarantees as part of the normal course of business and the sale of certain assets. These guarantees are not expected to have a material impact on the Company's consolidated financial results. |

Plaintiffs occasionally seek punitive or exemplary damages. PacifiCorp does not believe that such normal and routine litigation will have a material impact on its consolidated financial results. Environmental Laws and Regulations PacifiCorp is subject to federal, state and local laws and regulations regarding climate change, renewable portfolio standards, air and water quality, emissions performance standards, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact PacifiCorp's current and future operations. PacifiCorp believes it is in material compliance with all applicable laws and regulations. Hydroelectric Relicensing PacifiCorp is a party to the 2016 amended Klamath Hydroelectric Settlement Agreement ("KHSA"), which is intended to resolve disputes surrounding PacifiCorp's efforts to relicense the Klamath Hydroelectric Project. The KHSA does not guarantee dam removal. Instead, it establishes a process for PacifiCorp, the states of Oregon and California ("States") and other stakeholders to assess whether dam removal can occur consistent with the settlement's terms. For PacifiCorp, the key elements of the settlement include: (1) a contribution from PacifiCorp's Oregon and California customers capped at $200 million plus $250 million in California bond funds; (2) complete indemnification from harms associated with dam removal; (3) transfer of the Federal Energy Regulatory Commission ("FERC") license to a third-party dam removal entity, the Klamath River Renewal Corporation ("KRRC"), who would conduct dam removal; and (4) ability for PacifiCorp to operate the facilities for the benefit of customers until dam removal commences. In September 2016, the KRRC and PacifiCorp filed a joint application with the FERC to transfer the license for the four main-stem Klamath dams from PacifiCorp to the KRRC. The FERC approved partial transfer of the Klamath license in July 2020, subject to the condition that PacifiCorp remains co-licensee. Under the amended KHSA, PacifiCorp did not agree to remain co-licensee during the surrender and removal process given concerns about liability protections for PacifiCorp and its customers. The order does not immediately take effect, and PacifiCorp is evaluating the order in coordination with its settlement partners, including continued implementation of the agreement.

Easements During the six-month period ended June 30, 2020 , MidAmerican Energy entered into non-cancelable easements with minimum payment commitments totaling $98 million through 2060 for land in Iowa on which some of its wind-powered generating facilities will be located. Maintenance and Service Contracts During the six-month period ended June 30, 2020 , MidAmerican Energy entered into non-cancelable maintenance and service contracts related to wind-powered generating facilities with minimum payment commitments totaling $72 million through 2031 . Legal Matters MidAmerican Energy is party to a variety of legal actions arising out of the normal course of business. Plaintiffs occasionally seek punitive or exemplary damages. MidAmerican Energy does not believe that such normal and routine litigation will have a material impact on its financial results. Environmental Laws and Regulations MidAmerican Energy is subject to federal, state and local laws and regulations regarding climate change, renewable portfolio standards ("RPS"), air and water quality, emissions performance standards, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact its current and future operations. MidAmerican Energy believes it is in material compliance with all applicable laws and regulations. Transmission Rates MidAmerican Energy's wholesale transmission rates are set annually using FERC-approved formula rates subject to true-up for actual cost of service. MidAmerican Energy is authorized by the FERC to include a 0.50% adder beyond the approved base return on equity ("ROE") effective January 2015. Prior to September 2016, the rates in effect were based on a 12.38% ROE. In November 2013 and February 2015, a coalition of intervenors filed successive complaints with the FERC requesting that the 12.38% ROE no longer be found just and reasonable and sought to reduce the base ROE to 9.15% and 8.67% , respectively. In September 2016, the FERC issued an order for the first complaint, which reduces the base ROE to 10.32% and required refunds, plus interest, for the period from November 2013 through February 2015. Customer refunds relative to the first complaint occurred in February 2017. In November 2019, the FERC issued an order addressing the second complaint and issues on appeal in the first complaint. The order established a ROE of 9.88% ( 10.38% including the 0.50% adder) for the 15-month refund period of the first complaint and prospectively from September 2016 forward. In May 2020, the FERC issued an order on rehearing of the November 2019 order. The May 2020 order affirmed the FERC's prior decision to dismiss the second complaint and established an ROE of 10.02% ( 10.52% including the 0.50% adder) for the 15-month refund period of the first complaint and prospectively from September 2016 to the date of the May 2020 order. These orders continue to be subject to judicial appeal. MidAmerican Energy cannot predict the ultimate outcome of these matters and, as of June 30, 2020 , has accrued a $12 million liability for refunds of amounts collected under the higher ROE during the periods covered by both complaints. |

Segment Reporting Information [Line Items] | |
Segment Reporting Disclosure [Text Block] | Segment Information MidAmerican Energy has identified two reportable segments: regulated electric and regulated natural gas. The regulated electric segment derives most of its revenue from regulated retail sales of electricity to residential, commercial, and industrial customers and from wholesale sales. The regulated natural gas segment derives most of its revenue from regulated retail sales of natural gas to residential, commercial, and industrial customers and also obtains revenue by transporting natural gas owned by others through its distribution system. Pricing for regulated electric and regulated natural gas sales are established separately by regulatory agencies; therefore, management also reviews each segment separately to make decisions regarding allocation of resources and in evaluating performance. Common operating costs, interest income, interest expense and income tax expense are allocated to each segment based on certain factors, which primarily relate to the nature of the cost.

Wind-powered generating facilities are eligible for the credits for 10 years from the date the qualifying generating facilities are placed in-service. Amortization of excess deferred income taxes is primarily attributable to the amortization of $30 million of Oregon allocated excess deferred income taxes pursuant to the Oregon Renewable Adjustment Clause settlement, whereby a portion of Oregon allocated excess deferred income taxes was used to accelerate depreciation on Oregon's share of certain repowered wind facilities. Berkshire Hathaway includes BHE and its subsidiaries in its United States federal income tax return. Consistent with established regulatory practice, PacifiCorp's provision for federal and state income tax has been computed on a stand-alone basis, and substantially all of its currently payable or receivable income tax is remitted to or received from BHE. For the six-month periods ended June 30, 2020 and 2019, PacifiCorp made net cash payments for federal and state income tax to BHE totaling $42 million and $11 million , respectively. |
