Segment and Related Information | 3. Segment and Related Information (PPL) See Note 2 in PPL's 2020 Form 10-K for a discussion of reportable segments and related information.

Earnings Per Share [Abstract] | |
Earnings Per Share | 5. Earnings Per Share (PPL) Basic EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding during the applicable period. Diluted EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding, increased by incremental shares that would be outstanding if potentially dilutive share-based payment awards were converted to common shares as calculated using the Two-Class Method or Treasury Stock Method. Reconciliations of the amounts of income and shares of PPL common stock (in thousands) for the periods ended March 31 used in the EPS calculation are: Three Months 2021 2020 Income (Numerator) Income from continuing operations after income taxes available to PPL common shareowners - Basic and Diluted $ 203 $ 204 Income (loss) from discontinued operations (net of income taxes) available to PPL common shareowners - Basic and Diluted $ (2,043) $ 350 Net income (loss) available to PPL common shareowners - Basic and Diluted $ (1,840) $ 554 Shares of Common Stock (Denominator) Weighted-average shares - Basic EPS 769,159 767,948 Add: Dilutive share-based payment awards 1,551 790 Weighted-average shares - Diluted EPS 770,710 768,738 Basic and Diluted EPS Available to PPL common shareowners: Income from continuing operations after income taxes $ 0.26 $ 0.27 Income (loss) from discontinued operations (net of income taxes) (2.65) 0.45 Net Income (Loss) available to PPL common shareowners $ (2.39) $ 0.72 For the periods ended March 31, PPL issued common stock related to stock-based compensation plans and the DRIP as follows (in thousands): Three Months 2021 2020 Stock-based compensation plans 520 598 DRIP — 434 For the periods ended March 31, the following shares (in thousands) were excluded from the computations of diluted EPS because the effect would have been antidilutive.

Regulatory Matters Kentucky Activities ( PPL, LKE, LG&E and KU ) Rate Case Proceedings On November 25, 2020, LG&E and KU filed requests with the KPSC for an increase in annual electricity and gas revenues of approximately $331 million ($131 million and $170 million in electricity revenues at LG&E and KU and $30 million in gas revenues at LG&E). The revenue increases would be an increase of 11.6% and 10.4% in electricity revenues at LG&E and KU, and an increase of 8.3% in gas revenues at LG&E. In recognition of the economic impact of COVID-19, LG&E and KU requested approval of a one-year billing credit which will credit customers approximately $53 million ($41 million at LG&E and $12 million at KU). The billing credit represents the return to customers of certain regulatory liabilities on LG&E’s and KU’s Balance Sheets and serves to partially mitigate the rate increases during the first year in which the new rates are in effect. LG&E’s and KU’s applications also included a request for a CPCN to deploy Advanced Metering Infrastructure across LG&E’s and KU’s service territories in Kentucky. The applications were based on a forecasted test year of July 1, 2021 through June 30, 2022 and requested an authorized return on equity of 10.0%. On April 19, 2021, LG&E and KU entered into an agreement with all intervening parties to the proceedings resolving all matters in their applications, with the explicit exception of LG&E's and KU's net metering proposals. The agreement proposes increases in annual revenues of $217 million ($77 million and $116 million in electricity revenues at LG&E and KU and $24 million in gas revenues at LG&E) based on an authorized return on equity of 9.55%. The proposal includes an authorized 9.35% return on equity for the ECR and GLT mechanisms. The agreement does not modify the requested one-year billing credit. The agreement proposes that the KPSC should grant LG&E’s and KU’s request for a CPCN to deploy Advanced Metering Infrastructure and proposes the establishment of a Retired Asset Recovery rider (RAR) to provide for recovery of and return on the remaining investment in certain electric generating units upon their retirement over a ten-year period following retirement. In respect of the RAR rider, the agreement proposes that LG&E and KU will continue to use currently approved depreciation rates for Mill Creek units 1 and 2 and Brown Unit 3. The agreement also proposes a four-year “stay-out” commitment from LG&E and KU to refrain from effective base rate increases before July 1, 2025, subject to certain exceptions. A hearing on the agreement, and the underlying proceedings, was completed on April 28, 2021. Subject to KPSC approval, the rates, decreased by the amount of the billing credit, are expected to become effective July 1, 2021. An Order on the net metering issues is expected by the end of September 2021. PPL, LKE, LG&E and KU cannot predict the outcome of these proceedings. Pennsylvania Activities ( PPL and PPL Electric ) Act 129 Act 129 requires Pennsylvania Electric Distribution Companies (EDCs) to meet, by specified dates, specified goals for reduction in customer electricity usage and peak demand. EDCs not meeting the requirements of Act 129 are subject to significant penalties. PPL Electric filed with the PUC its Act 129 Phase IV Energy Efficiency and Conservation Plan (Phase IV Act 129 Plan) on November 30, 2020, for the five-year period starting June 1, 2021 and ending on May 31, 2026. PPL Electric's Phase IV Act 129 Plan was approved by the PUC at its March 25, 2021, public meeting. Federal Matters Challenge to PPL Electric Transmission Formula Rate Return on Equity (PPL and PPL Electric) On May 21, 2020, PP&L Industrial Customer Alliance (PPLICA) filed a complaint with the FERC alleging that PPL Electric's base return on equity (ROE) of 11.18% used to determine PPL Electric's formula transmission rate is unjust and unreasonable, and proposing an alternative ROE of 8.0% based on its interpretation of FERC Opinion No. 569. However, also on May 21, 2020, the FERC issued Opinion No. 569-A in response to numerous requests for rehearing of Opinion No. 569, which revised the method for analyzing base ROE. On June 10, 2020, PPLICA filed a Motion to Supplement the May 21, 2020 complaint in which PPLICA continued to allege that PPL Electric’s base ROE is unjust and unreasonable, but revised its analysis of PPL Electric's base ROE to reflect the guidance provided in Opinion No. 569-A. The amended complaint proposed an updated alternative ROE of 8.5% and also requested that the FERC preserve the original refund effective date as established by the filing of the original complaint on May 21, 2020. Several parties have filed motions to intervene, including one party who filed Comments in Support of the original complaint. On July 10, 2020, PPL Electric filed its Answer and supporting Testimony to the PPLICA filings arguing that the FERC should deny the original and amended complaints as they are without merit and fail to demonstrate the existing base ROE is unjust and unreasonable. In addition, PPL Electric contended any refund effective date should be set for no earlier than June 10, 2020 and PPLICA's proposed replacement ROE should be rejected. On October 15, 2020, the FERC issued an order on the PPLICA complaints which established hearing and settlement procedures, set a refund effective date of May 21, 2020 and granted the motions to intervene. On November 16, 2020, PPL Electric filed a request for rehearing of the portion of the October 15, 2020 Order that set the May 21, 2020 refund effective date. On December 17, 2020, the FERC issued a Notice of Denial of Rehearing by Operation of Law and Providing for Further Consideration. On February 16 and April 19, 2021, PPL Electric filed Petitions for Review with the United States Court of Appeals for the District of Columbia Circuit of the portion of the October 15, 2020 Order that set the May 21, 2020 refund effective date. PPL Electric continues to believe its ROE is just and reasonable and that it has meritorious defenses against the original and amended complaints. Settlement negotiations are currently proceeding, but there can be no assurance that they will result in a final settlement. Although PPL Electric cannot predict the outcome of this matter, in the first quarter of 2021, PPL Electric recorded a revenue reserve of $19 million after-tax. Of this amount, $13 million relates to the period from May 21, 2020 to December 31, 2020. Additional revenue earned from May 21, 2020 through the ultimate resolution of this matter may be subject to refund. A change of 50 basis points to the base ROE would impact PPL Electric's net income by approximately $12 million on an annual basis. FERC Transmission Rate Filing (PPL, LKE, LG&E and KU) In 2018, LG&E and KU applied to the FERC requesting elimination of certain on-going credits to a sub-set of transmission customers relating to the 1998 merger of LG&E's and KU's parent entities and the 2006 withdrawal of LG&E and KU from the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission operator and energy market. The application sought termination of LG&E's and KU's commitment to provide certain Kentucky municipalities mitigation for certain horizontal market power concerns arising out of the 1998 LG&E and KU merger and 2006 MISO withdrawal. The amounts at issue are generally waivers or credits granted to a limited number of Kentucky municipalities for either certain LG&E and KU or MISO transmission charges incurred for transmission service received. Due to the development of robust, accessible energy markets over time, LG&E and KU believe the mitigation commitments are no longer relevant or appropriate. In March 2019, the FERC granted LG&E's and KU's request to remove the ongoing credits, conditioned upon the implementation by LG&E and KU of a transition mechanism for certain existing power supply arrangements, subject to FERC review and approval. In July 2019, LG&E and KU proposed their transition mechanism to the FERC and in September 2019, the FERC rejected the proposed transition mechanism. In September 2020, the FERC issued orders in the rehearing process that modified various aspects of the September 2019 orders which had approved future termination of the credits, including adjusting which customer arrangements are covered by the transition mechanism and respective future periods or dates for termination of credits. In November 2020, the FERC denied the parties' rehearing requests. In November 2020 and January 2021, LG&E and KU and other parties appealed the September 2020 and November 2020 orders at the D.C. Circuit Court of Appeals. The appellate proceedings are continuing, and also include certain additional prior pending petitions for review relating to the matter. On January 15, 2021, LG&E and KU made a filing seeking FERC acceptance of a new proposal for a transition mechanism. On March 16, 2021, the FERC accepted the filed transition mechanism agreements effective on March 17, 2021 but subject to refund, and established hearing and settlement procedures. LG&E and KU are also required to make certain compliance filings consistent with the March 16, 2021 order. LG&E and KU cannot predict the outcome of the respective appellate and FERC proceedings. LG&E and KU currently receive recovery of the waivers and credits provided through other rate mechanisms and such rate recovery would be anticipated to be adjusted consistent with potential changes or terminations of the waivers and credits, as such become effective.

Commitments and Contingencies | 11. Commitments and Contingencies Legal Matters (All Registrants) PPL and its subsidiaries are involved in legal proceedings, claims and litigation in the ordinary course of business. PPL and its subsidiaries cannot predict the outcome of such matters, or whether such matters may result in material liabilities, unless otherwise noted. Talen Litigation (PPL) Background In September 2013, one of PPL's former subsidiaries, PPL Montana entered into an agreement to sell its hydroelectric generating facilities. In June 2014, PPL and PPL Energy Supply, the parent company of PPL Montana, entered into various definitive agreements with affiliates of Riverstone to spin off PPL Energy Supply and ultimately combine it with Riverstone's competitive power generation businesses to form a stand-alone company named Talen Energy. In November 2014, after executing the spinoff agreements but prior to the closing of the spinoff transaction, PPL Montana closed the sale of its hydroelectric generating facilities. Subsequently, on June 1, 2015, the spinoff of PPL Energy Supply was completed. Following the spinoff transaction, PPL had no continuing ownership interest in or control of PPL Energy Supply. In connection with the spinoff transaction, PPL Montana became Talen Montana, LLC (Talen Montana), a subsidiary of Talen Energy. Talen Energy Marketing also became a subsidiary of Talen Energy as a result of the June 2015 spinoff of PPL Energy Supply. Talen Energy has owned and operated both Talen Montana and Talen Energy Marketing since the spinoff. At the time of the spinoff, affiliates of Riverstone acquired a 35% ownership interest in Talen Energy. Riverstone subsequently acquired the remaining interests in Talen Energy in a take private transaction in December 2016. Talen Montana Retirement Plan and Talen Energy Marketing, LLC, Individually and on Behalf of All Others Similarly Situated v. PPL Corporation et al. On October 29, 2018, Talen Montana Retirement Plan and Talen Energy Marketing filed a putative class action complaint on behalf of current and contingent creditors of Talen Montana who allegedly suffered harm or allegedly will suffer reasonably foreseeable harm as a result of a November 2014 distribution of proceeds from the sale of then-PPL Montana's hydroelectric generating facilities. The action was filed in the Sixteenth Judicial District of the State of Montana, Rosebud County, against PPL and certain of its affiliates and current and former officers and directors (Talen Putative Class Action). Plaintiff asserts claims for, among other things, fraudulent transfer, both actual and constructive; recovery against subsequent transferees; civil conspiracy; aiding and abetting tortious conduct; and unjust enrichment. Plaintiff is seeking avoidance of the purportedly fraudulent transfer, unspecified damages, including punitive damages, the imposition of a constructive trust, and other relief. In December 2018, PPL removed the Talen Putative Class Action from the Sixteenth Judicial District of the State of Montana to the United States District Court for the District of Montana, Billings Division (MT Federal Court). In January 2019, the plaintiff moved to remand the Talen Putative Class Action back to state court, and dismissed without prejudice all current and former PPL Corporation directors from the case. In September 2019, the MT Federal Court granted plaintiff's motion to remand the case back to state court. Although, the PPL defendants petitioned the Ninth Circuit Court of Appeals to grant an appeal of the remand decision, in November 2019, the Ninth Circuit Court of Appeals denied that request and in December 2019, Talen Montana Retirement Plan filed a Second Amended Complaint in the Sixteenth Judicial District of the State of Montana, Rosebud County, which removed Talen Energy Marketing as a plaintiff. In January 2020, PPL defendants filed a motion to dismiss the Second Amended Complaint or, in the alternative, to stay the proceedings pending the resolution of the below mentioned Delaware Action. The Court held a hearing on June 24, 2020 regarding the motions. On September 11, 2020, the Court granted PPL defendants' alternative Motion for a Stay of the proceedings. PPL Corporation et al. vs. Riverstone Holdings LLC, Talen Energy Corporation et al. On November 30, 2018, PPL, certain PPL affiliates, and certain current and former officers and directors (PPL plaintiffs) filed a complaint in the Court of Chancery of the State of Delaware seeking various forms of relief against Riverstone, Talen Energy and certain of their affiliates (Delaware Action), in response to and as part of the defense strategy for an action filed by Talen Montana, LLC (the Talen Direct Action, since dismissed) and the Talen Putative Class Action described above (together, the Montana Actions) originally filed in Montana state court in October 2018. In the complaint, the PPL plaintiffs ask the Delaware Court of Chancery for declaratory and injunctive relief. This includes a declaratory judgment that, under the separation agreement governing the spinoff of PPL Energy Supply, all related claims that arise must be heard in Delaware; that the statute of limitations in Delaware and the spinoff agreement bar these claims at this time; that PPL is not liable for the claims in either the Talen Direct Action or the Talen Putative Class Action as PPL Montana was solvent at all relevant times; and that the separation agreement requires that Talen Energy indemnify PPL for all losses arising from the debts of Talen Montana, among other things. PPL's complaint also seeks damages against Riverstone for interfering with the separation agreement and against Riverstone affiliates for breach of the implied covenant of good faith and fair dealing. The complaint was subsequently amended on January 11, 2019 and March 20, 2019, to include, among other things, claims related to indemnification with respect to the Montana Actions, request a declaration that the Montana Actions are time-barred under the spinoff agreements, and allege additional facts to support the tortious interference claim. In April 2019, the defendants filed motions to dismiss the amended complaint. In July 2019, the Court heard oral arguments from the parties regarding the motions to dismiss, and in October 2019, the Delaware Court of Chancery issued an opinion sustaining all of the PPL plaintiffs' claims except for the claim for breach of implied covenant of good faith and fair dealing. As a result of the dismissal of the Talen Direct Action in December 2019, in January 2020, Talen Energy filed a new motion to dismiss five of the remaining eight claims in the amended complaint. The Court heard oral argument on the motion to dismiss on May 28, 2020, and on June 22, 2020, issued an opinion denying the motion in its entirety. Discovery is proceeding, and a trial has been scheduled for February 2022. With respect to each of the Talen-related matters described above, PPL believes that the 2014 distribution of proceeds was made in compliance with all applicable laws and that PPL Montana was solvent at all relevant times. Additionally, the agreements entered into in connection with the spinoff, which PPL and affiliates of Talen Energy and Riverstone negotiated and executed prior to the 2014 distribution, directly address the treatment of the proceeds from the sale of PPL Montana's hydroelectric generating facilities; in those agreements, Talen Energy and Riverstone definitively agreed that PPL was entitled to retain the proceeds. PPL believes that it has meritorious defenses to the claims made in the Talen Putative Class Action and intends to continue to vigorously defend against this action. The Talen Putative Class Action and the Delaware Action are both in early stages of litigation; at this time, PPL cannot predict the outcome of these matters or estimate the range of possible losses, if any, that PPL might incur as a result of the claims, although they could be material. (PPL, LKE and LG&E) Cane Run Environmental Claims In December 2013, six residents, on behalf of themselves and others similarly situated, filed a class action complaint against LG&E and PPL in the U.S. District Court for the Western District of Kentucky (U.S. District Court) alleging violations of the Clean Air Act, RCRA, and common law claims of nuisance, trespass and negligence. In July 2014, the U.S. District Court dismissed the RCRA claims and all but one Clean Air Act claim, but declined to dismiss the common law tort claims. In February 2017, the U.S. District Court dismissed PPL as a defendant and dismissed the final federal claim against LG&E, and in April 2017, issued an Order declining to exercise supplemental jurisdiction on the state law claims dismissing the case in its entirety. In June 2017, the plaintiffs filed a class action complaint in Jefferson County, Kentucky Circuit Court, against LG&E alleging state law nuisance, negligence and trespass tort claims. The plaintiffs seek compensatory and punitive damages for alleged property damage due to purported plant emissions on behalf of a class of residents within one to three miles of the plant. On January 8, 2020, the Jefferson Circuit Court issued an order denying the plaintiffs’ request for class certification. On January 14, 2020, the plaintiffs filed a notice of appeal in the Kentucky Court of Appeals. On December 11, 2020, the Court of Appeals issued an order affirming the lower court’s denial of class certification. In December 2020, plaintiffs filed a petition for discretionary review with the Kentucky Supreme Court. On April 21, 2021, the Kentucky Supreme Court denied further review of the lower court order. The case will be remanded to the Jefferson Circuit Court for the claims of the three remaining petitioners to be heard on an individual basis. PPL, LKE and LG&E cannot predict the ultimate outcome of the remaining proceedings, but do not anticipate this matter will have a material impact on operations or financial condition. ( PPL, LKE and KU) E.W. Brown Environmental Claims In July 2017, the Kentucky Waterways Alliance and the Sierra Club filed a citizen suit complaint against KU in the U.S. District Court for the Eastern District of Kentucky (U.S. District Court) alleging discharges at the E.W. Brown plant in violation of the Clean Water Act and the plant's water discharge permit and alleging contamination that may present an imminent and substantial endangerment in violation of the RCRA. The plaintiffs' suit relates to prior notices of intent to file a citizen suit submitted in October and November 2015 and October 2016. These plaintiffs sought injunctive relief ordering KU to take all actions necessary to comply with the Clean Water Act and RCRA, including ceasing the discharges in question, abating effects associated with prior discharges and eliminating the alleged imminent and substantial endangerment. These plaintiffs also sought assessment of civil penalties and an award of litigation costs and attorney fees. In December 2017, the U.S. District Court issued an Order dismissing the Clean Water Act and RCRA complaints against KU in their entirety. In January 2018, the plaintiffs appealed the dismissal Order to the U.S. Court of Appeals for the Sixth Circuit. In September 2018, the U.S. Court of Appeals for the Sixth Circuit issued its ruling affirming the lower court's decision to dismiss the Clean Water Act claims but reversing its dismissal of the RCRA claims against KU and remanding the latter to the U.S. District Court. In October 2018, KU filed a petition for rehearing to the U.S. Court of Appeals for the Sixth Circuit regarding the RCRA claims. In November 2018, the U.S. Court of Appeals for the Sixth Circuit denied KU's petition for rehearing regarding the RCRA claims. In January 2019, KU filed an answer to plaintiffs’ complaint in the U.S. District Court. Discovery is complete and the parties' motions for partial summary judgment are pending. In December 2020, the U.S. District Court delayed the trial scheduled for February 2, 2021 indefinitely due to pandemic considerations. PPL, LKE and KU cannot predict the outcome of these matters and an estimate or range of possible losses cannot be determined. KU is undertaking extensive remedial measures at the E.W. Brown plant including closure of the former ash pond, implementation of a groundwater remedial action plan and performance of a corrective action plan including aquatic study of adjacent surface waters and risk assessment. The aquatic study and risk assessment are being undertaken pursuant to a 2017 agreed Order with the Kentucky Energy and Environment Cabinet (KEEC). KU conducted sampling of Herrington Lake in 2017 and 2018. In June 2019, KU submitted to the KEEC the required aquatic study and risk assessment, conducted by an independent third-party consultant, finding that discharges from the E.W. Brown plant have not had any significant impact on Herrington Lake and that the water in the lake is safe for recreational use and meets safe drinking water standards. However, until the KEEC assesses the study and issues any regulatory determinations, PPL, LKE and KU are unable to determine whether additional remedial measures will be required at the E.W. Brown plant. Air Sulfuric Acid Mist Emissions (PPL, LKE and LG&E) In June 2016, the EPA issued a notice of violation under the Clean Air Act alleging that LG&E violated applicable rules relating to sulfuric acid mist emissions at its Mill Creek plant. The notice alleges failure to install proper controls, failure to operate the facility consistent with good air pollution control practice, and causing emissions exceeding applicable requirements or constituting a nuisance or endangerment. LG&E believes it has complied with applicable regulations during the relevant time period. On July 31, 2020, the U.S. Department of Justice and Louisville Metro Air Pollution Control District filed a complaint in the U.S. District Court for the Western District of Kentucky alleging violations specified in the EPA notice of violation and seeking civil penalties and injunctive relief. In October 2020, LG&E filed a motion to dismiss the complaint. In December 2020, the U.S. Department of Justice and the Louisville Metro Air Pollution Control District filed an amended complaint. In February 2021, LG&E filed a renewed motion to dismiss regarding the amended complaint. PPL, LKE and LG&E are unable to predict the outcome of this matter or the potential impact on operations of the Mill Creek plant, including increased capital or operating costs, and potential civil penalties or remedial measures, if any. An estimate or range of possible losses cannot be determined. Water/Waste (PPL, LKE, LG&E and KU) ELGs In 2015, the EPA finalized ELGs for wastewater discharge permits for new and existing steam electricity generating facilities. These guidelines require deployment of additional control technologies providing physical, chemical and biological treatment and mandate operational changes including "no discharge" requirements for certain wastewaters. The implementation date for individual generating stations was to be determined by the states on a case-by-case basis according to criteria provided by the EPA. Legal challenges to the final rule were consolidated before the U.S. Court of Appeals for the Fifth Circuit. In April 2017, the EPA announced that it would grant petitions for reconsideration of the rule. In September 2017, the EPA issued a rule to postpone the compliance date for certain requirements. On October 13, 2020, the EPA published final revisions to its best available technology standards for certain wastewaters and potential extensions to compliance dates. The rule is expected to be implemented by the states or applicable permitting authorities in the course of their normal permitting activities. LG&E and KU are currently implementing responsive compliance strategies and schedules. Certain aspects of these compliance plans and estimates relate to developments in state water quality standards, which are separate from the ELG rule or its implementation. Certain costs are included in the Registrants' capital plans and expected to be recovered from customers through rate recovery mechanisms, but additional costs and recovery will depend on further regulatory developments at the state level. CCRs In 2015, the EPA issued a final rule governing management of CCRs which include fly ash, bottom ash and sulfur dioxide scrubber wastes. The CCR Rule imposes extensive new requirements for certain CCR impoundments and landfills, including public notifications, location restrictions, design and operating standards, groundwater monitoring and corrective action requirements, and closure and post-closure care requirements, and specifies restrictions relating to the beneficial use of CCRs. In July 2018, the EPA issued a final rule extending the deadline for closure of certain impoundments and adopting other substantive changes. In August 2018, the D.C. Circuit Court of Appeals vacated and remanded portions of the CCR Rule. In December 2019, the EPA addressed the deficiencies identified by the court and proposed amendments to change the closure deadline. In August 2020, the EPA published a final rule extending the deadline to initiate closure to April 11, 2021, while providing for certain extensions. The EPA is conducting ongoing rulemaking actions regarding various other amendments to the rule. Certain ongoing legal challenges to various provisions of the CCR Rule have been held in abeyance pending review by the EPA pursuant to the President's executive order. PPL, LKE, LG&E and KU are unable to predict the outcome of the ongoing litigation and rulemaking or potential impacts on current LG&E and KU compliance plans. The Registrants are currently finalizing closure plans and schedules. In January 2017, Kentucky issued a new state rule relating to CCR management, effective May 2017, aimed at reflecting the requirements of the federal CCR rule. As a result of a subsequent legal challenge, in January 2018, the Franklin County, Kentucky Circuit Court issued an opinion invalidating certain procedural elements of the rule. LG&E and KU presently operate their facilities under continuing permits authorized under the former program and do not currently anticipate material impacts as a result of the judicial ruling. The Kentucky Energy and Environmental Cabinet has announced it intends to propose new state rules aimed at addressing procedural deficiencies identified by the court and providing the regulatory framework necessary for operation of the state program in lieu of the federal CCR Rule. Associated costs are expected to be subject to rate recovery. LG&E and KU received KPSC approval for a compliance plan providing for the closure of impoundments at the Mill Creek, Trimble County, E.W. Brown, and Ghent stations, and construction of process water management facilities at those plants. In addition to the foregoing measures required for compliance with the federal CCR rule, KU also received KPSC approval for its plans to close impoundments at the retired Green River, Pineville and Tyrone plants to comply with applicable state law. As of April 2021, LG&E and KU have commenced closure of all of the subject impoundments and have completed closure of some of their smaller impoundments. LG&E and KU generally expect to complete impoundment closures within five years of commencement, although a longer period may be required to complete closure of some facilities. Associated costs are expected to be subject to rate recovery. In connection with the final CCR rule, LG&E and KU recorded adjustments to existing AROs beginning in 2015 and continue to record adjustments as required. See Note 16 for additional information. Further changes to AROs, current capital plans or operating costs may be required as estimates are refined based on closure developments, groundwater monitoring results, and regulatory or legal proceedings. Costs relating to this rule are subject to rate recovery. (All Registrants) Superfund and Other Remediation PPL Electric, LG&E and KU are potentially responsible for investigating and remediating contamination under the federal Superfund program and similar state programs. Actions are under way at certain sites including former coal gas manufacturing plants in Pennsylvania and Kentucky previously owned or operated by, or currently owned by predecessors or affiliates of, PPL Electric, LG&E and KU. PPL Electric is potentially responsible for a share of clean-up costs at certain sites including the Columbia Gas Plant site and the Brodhead site. Cleanup actions have been or are being undertaken at these sites as requested by governmental agencies, the costs of which have not been and are not expected to be significant to PPL Electric. As of March 31, 2021 and December 31, 2020, PPL Electric had a recorded liability of $10 million representing its best estimate of the probable loss incurred to remediate the sites identified above. Depending on the outcome of investigations at identified sites where investigations have not begun or been completed, or developments at sites for which information is incomplete, additional costs of remediation could be incurred. PPL Electric, LG&E and KU lack sufficient information about such additional sites to estimate any potential liability or range of reasonably possible losses, if any, related to these sites. Such costs, however, are not currently expected to be significant. The EPA is evaluating the risks associated with polycyclic aromatic hydrocarbons and naphthalene, chemical by-products of coal gas manufacturing. As a result, individual states may establish stricter standards for water quality and soil cleanup, that could require several PPL subsidiaries to take more extensive assessment and remedial actions at former coal gas manufacturing plants. PPL, PPL Electric, LKE, LG&E and KU cannot estimate a range of possible losses, if any, related to these matters. Regulatory Issues ( All Registrants) See Note 7 for information on regulatory matters related to utility rate regulation. Electricity - Reliability Standards The NERC is responsible for establishing and enforcing mandatory reliability standards (Reliability Standards) regarding the bulk electric system in North America. The FERC oversees this process and independently enforces the Reliability Standards. The Reliability Standards have the force and effect of law and apply to certain users of the bulk electric system, including electric utility companies, generators and marketers. Under the Federal Power Act, the FERC may assess civil penalties for certain violations. PPL Electric, LG&E and KU monitor their compliance with the Reliability Standards and self-report or self-log potential violations of applicable reliability requirements whenever identified, and submit accompanying mitigation plans, as required. The resolution of a small number of potential violations is pending. Penalties incurred to date have not been significant. Any Regional Reliability Entity determination concerning the resolution of violations of the Reliability Standards remains subject to the approval of the NERC and the FERC. In the course of implementing their programs to ensure compliance with the Reliability Standards by those PPL affiliates subject to the standards, certain other instances of potential non-compliance may be identified from time to time. The Registrants cannot predict the outcome of these matters, and an estimate or range of possible losses cannot be determined. Other Guarantees and Other Assurances (All Registrants) In the normal course of business, the Registrants enter into agreements that provide financial performance assurance to third parties on behalf of certain subsidiaries. Such agreements include, for example, guarantees, stand-by letters of credit issued by financial institutions and surety bonds issued by insurance companies. These agreements are entered into primarily to support or enhance the creditworthiness attributed to a subsidiary on a stand-alone basis or to facilitate the commercial activities in which these subsidiaries engage. (PPL) PPL fully and unconditionally guarantees all of the debt securities of PPL Capital Funding. (All Registrants) The table below details guarantees provided as of March 31, 2021. "Exposure" represents the estimated maximum potential amount of future payments that could be required to be made under the guarantee. The probability of expected payment/performance under each of these guarantees is remote except for "WPD guarantee of pension and other obligations of unconsolidated entities," for which PPL has a total recorded liability of $4 million at March 31, 2021 and $5 million at December 31, 2020 , which is included in “Current liabilities held for sale” on the Balance Sheets. For reporting purposes, on a consolidated basis, all guarantees of PPL Electric, LKE, LG&E and KU also apply to PPL, and all guarantees of LG&E and KU also apply to LKE. Exposure at March 31, 2021 Expiration PPL WPD indemnifications for entities in liquidation and sales of assets $ 11 (a) 2023 WPD guarantee of pension and other obligations of unconsolidated entities 96 (b) LKE Indemnification of lease termination and other divestitures $ 200 (c) 2021 LG&E and KU LG&E and KU obligation of shortfall related to OVEC (d) (a) Indemnification to the liquidators and certain others for existing liabilities or expenses or liabilities arising during the liquidation process. The indemnifications are limited to distributions made from the subsidiary to its parent either prior or subsequent to liquidation or are not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases where the agreements provide for specific limits. In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters or have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Additionally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties. (b) Relates to certain obligations of discontinued or modified electric associations that were guaranteed at the time of privatization by the participating members. Costs are allocated to the members and can be reallocated if an existing member becomes insolvent. At March 31, 2021, WPD has recorded an estimated discounted liability for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements, and as a result, the exposure has been estimated. (c) LKE provides certain indemnifications covering the due and punctual payment, performance and discharge by each party of its respective obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under a 2009 Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a maximum exposure of $200 million exclusive of certain items such as government fines and penalties that may exceed the maximum. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum exposures range from being capped at the sale price to no specified maximum. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. LKE cannot predict the ultimate outcomes of the various indemnification scenarios, but does not expect such outcomes to result in significant losses above the amounts recorded. (d) Pursuant to the OVEC power purchase contract, LG&E and KU are obligated to pay for their share of OVEC's excess debt service, post-retirement and decommissioning costs, as well as any shortfall from amounts included within a demand charge designed and expected to cover these costs over the term of the contract. LKE's proportionate share of OVEC's outstanding debt was $103 million at March 31, 2021, consisting of LG&E's share of $71 million and KU's share of $32 million. The maximum exposure and the expiration date of these potential obligations are not presently determinable. See "Energy Purchase Commitments" in Note 11 in PPL's, LKE's, LG&E's and KU's 2020 Form 10-K for additional information on the OVEC power purchase contract. In March 2018, a sponsor with a 4.85% pro-rata share of OVEC obligations filed for bankruptcy under Chapter 11 and, in August 2018, received a rejection order for the OVEC power purchase contract in the bankruptcy proceeding. OVEC and other entities challenged the contract rejection, the bankruptcy plan confirmation and regulatory aspects of the plan in various forums. In May 2020, OVEC and the relevant sponsor announced a settlement resolving all disputed matters in the bankruptcy and other proceedings, including providing that the sponsor will withdraw its request to reject the power purchase agreement. The settlement was implemented in July 2020. The Registrants provide other miscellaneous guarantees through contracts entered into in the normal course of business. These guarantees are primarily in the form of indemnification or warranties related to services or equipment and vary in duration. The amounts of these guarantees often are not explicitly stated, and the overall maximum amount of the obligation under such guarantees cannot be reasonably estimated. Historically, no significant payments have been made with respect to these types of guarantees and the probability of payment/performance under these guarantees is remote. PPL, on behalf of itself and certain of its subsidiaries, maintains insurance that covers liability assumed under contract for bodily injury and property damage. The coverage provides maximum aggregate coverage of $225 million. This insurance may be applicable to obligations under certain of these contractual arrangements. Risks and Uncertainties (All Registrants) The COVID-19 pandemic has disrupted the U.S. and global economies and continues to present extraordinary challenges to businesses, communities, workforces and markets. In the U.S. and throughout the world, governmental authorities have taken urgent and extensive actions to contain the spread of the virus and mitigate known or foreseeable impacts. In the Registrants’ service territories, mitigation measures have included quarantines, stay-at-home orders, travel restrictions, reduced operations or closures of businesses, schools and governmental agencies, and legislative or regulatory actions to address health or other pandemic-related concerns, all of which have the potential to adversely impact the Registrants' business and operations, especially if these measures remain in effect for a prolonged period of time. |

For all services companies, the costs of directly assignable and attributable services are charged to the respective recipients as direct support costs. General costs that cannot be directly attributed to a specific entity are allocated and charged to the respective recipients as indirect support costs. PPL Services and PPL EU Services use a three-factor methodology that includes the applicable recipients' invested capital, operation and maintenance expenses and number of employees to allocate indirect costs. PPL Services may also use a ratio of overall direct and indirect costs or a weighted average cost ratio. LKS bases its indirect allocations on the subsidiaries' number of employees, total assets, revenues, number of customers and/or other statistical information. PPL Services, PPL EU Services and LKS charged the following amounts for the periods ended March 31, including amounts applied to accounts that are further distributed between capital and expense on the books of the recipients, based on methods that are believed to be reasonable.

LG&E and KU also provide services to each other and to LKS. Billings between LG&E and KU relate to labor and overheads associated with union and hourly employees performing work for the other company, charges related to jointly-owned generating units and other miscellaneous charges. Tax settlements between LKE and LG&E and KU are reimbursed through LKS. Intercompany Borrowings (PPL Electric) PPL Energy Funding maintains a $650 million revolving line of credit with a PPL Electric subsidiary. No balance was outstanding at March 31, 2021 and December 31, 2020. The interest rates on borrowings are equal to one-month LIBOR plus a spread. Interest income is reflected in "Interest Income from Affiliate" on the Income Statements. (LKE) LKE maintains a $375 million revolving line of credit with a PPL Energy Funding subsidiary whereby LKE can borrow funds on a short-term basis at market-based rates. The interest rates on borrowings are equal to one-month LIBOR plus a spread. At March 31, 2021 and December 31, 2020, $227 million and $251 million were outstanding and reflected in "Notes payable with affiliates" on the Balance Sheets. The interest rates on the outstanding borrowings at March 31, 2021 and December 31, 2020 were 1.62% and 1.65%. Interest expense on the revolving line of credit was not significant for the three months ended March 31, 2021 and 2020. LKE maintains an agreement with a PPL affiliate that has a $300 million borrowing limit whereby LKE can loan funds on a short-term basis at market-based rates. No balance was outstanding at March 31, 2021 and December 31, 2020. The interest rate on the loan is based on the PPL affiliate's credit rating and equal to one-month LIBOR plus a spread. LKE maintains ten (LG&E and KU) LG&E participates in an intercompany money pool agreement whereby LKE and/or KU make available to LG&E funds up to the difference between LG&E's FERC borrowing limit and LG&E's commercial paper capacity limit at an interest rate based on the lower of a market index of commercial paper issues and two additional rate options based on LIBOR. LG&E's money pool borrowing limit is $325 million. No balances were outstanding at March 31, 2021 and December 31, 2020. KU participates in an intercompany money pool agreement whereby LKE and/or LG&E make available to KU funds up to the difference between KU's FERC borrowing limit and KU's commercial paper capacity limit at an interest rate based on the lower of a market index of commercial paper issues and two additional rate options based on LIBOR. KU's money pool borrowing limit is $300 million. No balances were outstanding at March 31, 2021 and December 31, 2020. VEBA Funds Receivable (PPL Electric) In May 2018, PPL received a favorable private letter ruling from the IRS permitting a transfer of excess funds from the PPL Bargaining Unit Retiree Health Plan VEBA to a new subaccount within the VEBA, to be used to pay medical claims of active bargaining unit employees. Based on PPL Electric's participation in PPL’s Other Postretirement Benefit plan, PPL Electric was allocated a portion of the excess funds from PPL Services. These funds have been recorded as an intercompany receivable on PPL Electric's Balance Sheets. The receivable balance decreases as PPL Electric pays incurred medical claims and is reimbursed by PPL Services. The intercompany receivable balance associated with these funds was $20 million as of March 31, 2021, of which $10 million was reflected in "Accounts receivable from affiliates" and $10 million was reflected in "Other noncurrent assets" on the PPL Electric Balance Sheet. The intercompany receivable balance associated with these funds was $22 million as of December 31, 2020, of which $10 million was reflected in "Accounts receivable from affiliates" and $12 million was reflected in "Other noncurrent assets" on the PPL Electric Balance Sheet.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 14. Fair Value Measurements (All Registrants) Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). A market approach (generally, data from market transactions), an income approach (generally, present value techniques and option-pricing models) and/or a cost approach (generally, replacement cost) are used to measure the fair value of an asset or liability, as appropriate. These valuation approaches incorporate inputs such as observable, independent market data and/or unobservable data that management believes are predicated on the assumptions market participants would use to price an asset or liability. These inputs may incorporate, as applicable, certain risks such as nonperformance risk, which includes credit risk. The fair value of a group of financial assets and liabilities is measured on a net basis. See Note 1 in each Registrant's 2020 Form 10-K for information on the levels in the fair value hierarchy. Recurring Fair Value Measurements The assets and liabilities measured at fair value were: March 31, 2021 December 31, 2020 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 PPL Assets Cash and cash equivalents $ 421 $ 421 $ — $ — $ 442 $ 442 $ — $ — Restricted cash and cash equivalents (a) 1 1 — — 1 1 — — Special use funds (a): Commingled debt fund measured at NAV (b) 25 — — — 26 — — — Commingled equity fund measured at NAV (b) 24 — — — 25 — — — Total special use funds 49 — — — 51 — — — Total assets $ 471 $ 422 $ — $ — $ 494 $ 443 $ — $ — Liabilities Price risk management liabilities (c): Interest rate swaps $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — Total price risk management liabilities $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — PPL Electric Assets Cash and cash equivalents $ 29 $ 29 $ — $ — $ 40 $ 40 $ — $ — Total assets $ 29 $ 29 $ — $ — $ 40 $ 40 $ — $ — LKE Assets Cash and cash equivalents $ 16 $ 16 $ — $ — $ 29 $ 29 $ — $ — Total assets $ 16 $ 16 $ — $ — $ 29 $ 29 $ — $ — Liabilities Price risk management liabilities: Interest rate swaps $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — Total price risk management liabilities $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — LG&E Assets Cash and cash equivalents $ 7 $ 7 $ — $ — $ 7 $ 7 $ — $ — Total assets $ 7 $ 7 $ — $ — $ 7 $ 7 $ — $ — March 31, 2021 December 31, 2020 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Liabilities Price risk management liabilities: Interest rate swaps $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — Total price risk management liabilities $ 17 $ — $ 17 $ — $ 23 $ — $ 23 $ — KU Assets Cash and cash equivalents $ 8 $ 8 $ — $ — $ 22 $ 22 $ — $ — Total assets $ 8 $ 8 $ — $ — $ 22 $ 22 $ — $ — (a) Included in "Other current assets" on the Balance Sheets.

The fair value amounts presented in the table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Balance Sheets. (c) Current portion is included in "Other current liabilities" and noncurrent portion is included in "Other deferred credits and noncurrent liabilities" on the Balance Sheets. Special Use Funds (PPL) The special use funds are investments restricted for paying active union employee medical costs. In May 2018, PPL received a favorable private letter ruling from the IRS permitting a transfer of excess funds from the PPL Bargaining Unit Retiree Health Plan VEBA to a new subaccount within the VEBA to be used to pay medical claims of active bargaining unit employees. The funds are invested primarily in commingled debt and equity funds measured at NAV and are classified as investments in equity securities. Changes in fair value of the funds are recorded to the Statements of Income. Price Risk Management Assets/Liabilities - Interest Rate Swaps/Foreign Currency Contracts/Cross-Currency Swaps ( PPL, LKE, LG&E and KU) To manage interest rate risk, PPL, LKE, LG&E and KU use interest rate contracts such as forward-starting swaps, floating-to-fixed swaps and fixed-to-floating swaps. To manage foreign currency exchange risk, PPL uses foreign currency contracts such as forwards, options and cross-currency swaps that contain characteristics of both interest rate and foreign currency contracts. An income approach is used to measure the fair value of these contracts, utilizing readily observable inputs, such as forward interest rates (e.g., LIBOR and government security rates) and forward foreign currency exchange rates (e.g., GBP), as well as inputs that may not be observable, such as credit valuation adjustments. In certain cases, market information cannot practicably be obtained to value credit risk and therefore internal models are relied upon. These models use projected probabilities of default and estimated recovery rates based on historical observances. When the credit valuation adjustment is significant to the overall valuation, the contracts are classified as Level 3. Nonrecurring Fair Value Measurements (PPL) See Note 9 for information regarding the estimated fair value of the U.K. utility business which is classified as held for sale as of March 31, 2021. Financial Instruments Not Recorded at Fair Value (All Registrants) The carrying amounts of long-term debt on the Balance Sheets and their estimated fair values are set forth below.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments and Hedging Activities | 15. Derivative Instruments and Hedging Activities Risk Management Objectives (All Registrants) PPL has a risk management policy approved by the Board of Directors to manage market risk associated with commodities, interest rates on debt issuances and foreign exchange (including price, liquidity and volumetric risk) and credit risk (including non-performance risk and payment default risk). The Risk Management Committee, comprised of senior management and chaired by the Senior Director-Risk Management, oversees the risk management function. Key risk control activities designed to ensure compliance with the risk policy and detailed programs include, but are not limited to, credit review and approval, validation of transactions, verification of risk and transaction limits, value-at-risk analyses (VaR, a statistical model that attempts to estimate the value of potential loss over a given holding period under normal market conditions at a given confidence level) and the coordination and reporting of the Enterprise Risk Management program. Market Risk Market risk includes the potential loss that may be incurred as a result of price changes associated with a particular financial or commodity instrument as well as market liquidity and volumetric risks. Forward contracts, futures contracts, options, swaps and structured transactions are utilized as part of risk management strategies to minimize unanticipated fluctuations in earnings caused by changes in commodity prices, interest rates and foreign currency exchange rates. Many of these contracts meet the definition of a derivative. All derivatives are recognized on the Balance Sheets at their fair value, unless NPNS is elected. The following summarizes the market risks that affect PPL and its subsidiaries. Interest Rate Risk • PPL and its subsidiaries are exposed to interest rate risk associated with forecasted fixed-rate and existing floating-rate debt issuances. PPL and WPD hold over-the-counter cross currency swaps to limit exposure to market fluctuations on interest and principal payments from changes in foreign currency exchange rates and interest rates. PPL, LKE and LG&E utilize over-the-counter interest rate swaps to limit exposure to market fluctuations on floating-rate debt. PPL, LKE, LG&E and KU utilize forward starting interest rate swaps to hedge changes in benchmark interest rates, when appropriate, in connection with future debt issuances. • PPL and its subsidiaries are exposed to interest rate risk associated with debt securities and derivatives held by defined benefit plans. This risk is significantly mitigated to the extent that the plans are sponsored at, or sponsored on behalf of, the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place. Foreign Currency Risk (PPL) • PPL is exposed to foreign currency exchange risk primarily associated with its investments in and earnings of U.K. affiliates. (All Registrants) Commodity Price Risk PPL is exposed to commodity price risk through its domestic subsidiaries as described below. • PPL Electric is required to purchase electricity to fulfill its obligation as a PLR. Potential commodity price risk is insignificant and mitigated through its PUC-approved cost recovery mechanism and full-requirement supply agreements to serve its PLR customers which transfer the risk to energy suppliers. • LG&E's and KU's rates include certain mechanisms for fuel, fuel-related expenses and energy purchases. In addition, LG&E's rates include a mechanism for natural gas supply expenses. These mechanisms generally provide for timely recovery of market price fluctuations associated with these expenses. Volumetric Risk Volumetric risk is the risk related to the changes in volume of retail sales due to weather, economic conditions or other factors. PPL is exposed to volumetric risk through its subsidiaries as described below. • WPD is exposed to volumetric risk which is significantly mitigated as a result of the method of regulation in the U.K. Under the RIIO-ED1 price control regulations, recovery of such exposure occurs on a two year lag. See Note 1 in PPL's 2020 Form 10-K for additional information on revenue recognition under RIIO-ED1. • PPL Electric, LG&E and KU are exposed to volumetric risk on retail sales, mainly due to weather and other economic conditions for which there is limited mitigation between rate cases. Equity Securities Price Risk • PPL and its subsidiaries are exposed to equity securities price risk associated with the fair value of the defined benefit plans' assets. This risk is significantly mitigated at the regulated domestic utilities and for certain plans at WPD due to the recovery methods in place. • PPL is exposed to equity securities price risk from future stock sales and/or purchases. Credit Risk Credit risk is the potential loss that may be incurred due to a counterparty's non-performance. PPL is exposed to credit risk from "in-the-money" interest rate derivatives with financial institutions, as well as additional credit risk through certain of its subsidiaries, as discussed below. In the event a supplier of PPL Electric, LG&E or KU defaults on its obligation, those Registrants would be required to seek replacement power or replacement fuel in the market. In general, subject to regulatory review or other processes, appropriate incremental costs incurred by these entities would be recoverable from customers through applicable rate mechanisms, thereby mitigating the financial risk for these entities. PPL and its subsidiaries have credit policies in place to manage credit risk, including the use of an established credit approval process, daily monitoring of counterparty positions and the use of master netting agreements or provisions. These agreements generally include credit mitigation provisions, such as margin, prepayment or collateral requirements. PPL and its subsidiaries may request additional credit assurance, in certain circumstances, in the event that the counterparties' credit ratings fall below investment grade, their tangible net worth falls below specified percentages or their exposures exceed an established credit limit. Master Netting Arrangements (PPL, LKE, LG&E and KU) Net derivative positions on the balance sheets are not offset against the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) under master netting arrangements. PPL had no obligation and an immaterial obligation to return cash collateral under master netting arrangements at March 31, 2021 and December 31, 2020. PPL had a $22 million obligation and no obligation to post cash collateral under master netting arrangements at March 31, 2021 and December 31, 2020. LKE, LG&E and KU had no obligation to return cash collateral under master netting arrangements at March 31, 2021 and December 31, 2020. LKE, LG&E and KU had no obligation to post cash collateral under master netting arrangements at March 31, 2021.and December 31, 2020. See "Offsetting Derivative Instruments" below for a summary of derivative positions presented in the balance sheets where a right of setoff exists under these arrangements. Interest Rate Risk (All Registrants) PPL and its subsidiaries issue debt to finance their operations, which exposes them to interest rate risk. A variety of financial derivative instruments are utilized to adjust the mix of fixed and floating interest rates in their debt portfolios, adjust the duration of the debt portfolios and lock in benchmark interest rates in anticipation of future financing, when appropriate. Risk limits under PPL's risk management program are designed to balance risk exposure to volatility in interest expense and changes in the fair value of the debt portfolio due to changes in benchmark interest rates. In addition, the interest rate risk of certain subsidiaries is potentially mitigated as a result of the existing regulatory framework or the timing of rate cases. Cash Flow Hedges (PPL) Interest rate risks include exposure to adverse interest rate movements for outstanding variable rate debt and for future anticipated financings. Financial interest rate swap contracts that qualify as cash flow hedges may be entered into to hedge floating interest rate risk associated with both existing and anticipated debt issuances. PPL had no such contracts at March 31, 2021. At March 31, 2021, PPL held an aggregate notional value in cross-currency interest rate swap contracts of $202 million that mature in 2028 to hedge the interest payments and principal of WPD's U.S. dollar-denominated senior notes. In March 2021, $500 million of WPD's U.S. dollar-denominated senior notes were repaid prior to maturity and $500 million notional value of cross-currency interest rate swap contracts matured. Cash flow hedges are discontinued if it is no longer probable that the original forecasted transaction will occur by the end of the originally specified time period and any amounts previously recorded in AOCI are reclassified into earnings once it is determined that the hedged transaction is not probable of occurring. For the three months ended March 31, 2021 and 2020, PPL had no cash flow hedges reclassified into earnings associated with discontinued cash flow hedges. At March 31, 2021, the amount of accumulated net unrecognized after-tax gains (losses) on qualifying derivatives expected to be reclassified into earnings during the next 12 months is insignificant. Amounts are reclassified as the hedged interest expense is recorded. Economic Activity (PPL, LKE and LG&E) LG&E enters into interest rate swap contracts that economically hedge interest payments. Because realized gains and losses from the swaps, including terminated swap contracts, are recoverable through regulated rates, any subsequent changes in fair value of these derivatives are included in regulatory assets or liabilities until they are realized as interest expense. Realized gains and losses are recognized in "Interest Expense" on the Statements of Income at the time the underlying hedged interest expense is recorded. At March 31, 2021, LG&E held contracts with a notional amount of $64 million that mature in 2033. Foreign Currency Risk (PPL) PPL is exposed to foreign currency risk, primarily through investments in and earnings of U.K. affiliates. PPL has adopted a foreign currency risk management program designed to hedge certain foreign currency exposures, including firm commitments, recognized assets or liabilities, anticipated transactions, including the anticipated sale of its U.K. utility business and net investments. In addition, PPL enters into financial instruments to protect against foreign currency translation risk of expected GBP earnings. Net Investment Hedges PPL enters into foreign currency contracts on behalf of a subsidiary to protect the value of a portion of its net investment in WPD. There were no contracts outstanding at March 31, 2021. At March 31, 2021 and December 31, 2020, PPL had $33 million of accumulated net investment hedge after tax gains (losses) that were included in the foreign currency translation adjustment component of AOCI. Economic Activity PPL enters into foreign currency contracts on behalf of a subsidiary to economically hedge GBP-denominated anticipated earnings and anticipated transactions, including the anticipated sale of its U.K. utility business. At March 31, 2021, the total exposure hedged by PPL was approximately £7.5 billion. Accounting and Reporting (All Registrants) All derivative instruments are recorded at fair value on the Balance Sheet as an asset or liability unless NPNS is elected. NPNS contracts include certain full requirement purchase contracts and other physical purchase contracts. Changes in the fair value of derivatives not designated as NPNS are recognized in earnings unless specific hedge accounting criteria are met and designated as such, except for the changes in fair values of LG&E's interest rate swaps that are recognized as regulatory assets or regulatory liabilities. See Note 7 for amounts recorded in regulatory assets and regulatory liabilities at March 31, 2021 and December 31, 2020. See Note 1 in each Registrant's 2020 Form 10-K for additional information on accounting policies related to derivative instruments.

Under the agreements, upon termination of the agreement as a result of a default or other termination event, the non-defaulting party typically would have a right to set off amounts owed under the agreement against any other obligations arising between the two parties (whether under the agreement or not), whether matured or contingent and irrespective of the currency, place of payment or place of booking of the obligation. PPL, LKE, LG&E and KU have elected not to offset derivative assets and liabilities and not to offset net derivative positions against the right to reclaim cash collateral pledged (an asset) or the obligation to return cash collateral received (a liability) under derivatives agreements. The table below summarizes the derivative positions presented in the balance sheets where a right of setoff exists under these arrangements and related cash collateral received or pledged. Assets Liabilities Eligible for Offset Eligible for Offset Gross Derivative Cash Net Gross Derivative Cash Net March 31, 2021 Treasury Derivatives PPL $ 62 $ 18 $ — $ 44 $ 197 $ 18 $ 22 $ 157 LKE — — — — 17 — — 17 LG&E — — — — 17 — — 17 Assets Liabilities Eligible for Offset Eligible for Offset Gross Derivative Cash Net Gross Derivative Cash Net December 31, 2020 Treasury Derivatives PPL $ 146 $ 34 $ — $ 112 $ 160 $ 34 $ — $ 126 LKE — — — — 23 — — 23 LG&E — — — — 23 — — 23 Credit Risk-Related Contingent Features Certain derivative contracts contain credit risk-related contingent features which, when in a net liability position, would permit the counterparties to require the transfer of additional collateral upon a decrease in the credit ratings of PPL, LKE, LG&E and KU or certain of their subsidiaries. Most of these features would require the transfer of additional collateral or permit the counterparty to terminate the contract if the applicable credit rating were to fall below investment grade. Some of these features also would allow the counterparty to require additional collateral upon each downgrade in credit rating at levels that remain above investment grade. In either case, if the applicable credit rating were to fall below investment grade, and assuming no assignment to an investment grade affiliate were allowed, most of these credit contingent features require either immediate payment of the net liability as a termination payment or immediate and ongoing full collateralization on derivative instruments in net liability positions. Additionally, certain derivative contracts contain credit risk-related contingent features that require adequate assurance of performance be provided if the other party has reasonable concerns regarding the performance of PPL's, LKE's, LG&E's and KU's obligations under the contracts. A counterparty demanding adequate assurance could require a transfer of additional collateral or other security, including letters of credit, cash and guarantees from a creditworthy entity. This would typically involve negotiations among the parties. However, amounts disclosed below represent assumed immediate payment or immediate and ongoing full collateralization for derivative instruments in net liability positions with "adequate assurance" features. (PPL) At March 31, 2021, derivative contracts in a net liability position that contain credit risk-related contingent features, collateral posted on those positions and the related effect of a decrease in credit ratings below investment grade are summarized as follows: PPL Aggregate fair value of derivative instruments in a net liability position with credit risk-related contingent features $ 161 Aggregate fair value of collateral posted on these derivative instruments 22 Aggregate fair value of additional collateral requirements in the event of a credit downgrade below investment grade (a) 139 (a) Includes the effect of net receivables and payables already recorded on the Balance Sheet. |

Interim Financial Statements | 1. Interim Financial Statements (All Registrants) Capitalized terms and abbreviations appearing in the unaudited combined notes to condensed financial statements are defined in the glossary. Dollars are in millions, except per share data, unless otherwise noted. The specific Registrant to which disclosures are applicable is identified in parenthetical headings in italics above the applicable disclosure or within the applicable disclosure for each Registrant's related activities and disclosures. Within combined disclosures, amounts are disclosed for any Registrant when significant. The accompanying unaudited condensed financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all of the information and footnote disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation in accordance with GAAP are reflected in the condensed financial statements. All adjustments are of a normal recurring nature, except as otherwise disclosed. Each Registrant's Balance Sheet at December 31, 2020 is derived from that Registrant's 2020 audited Balance Sheet. The financial statements and notes thereto should be read in conjunction with the financial statements and notes contained in each Registrant's 2020 Form 10-K. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021 or other future periods, because results for interim periods can be disproportionately influenced by various factors, developments and seasonal variations.

See Note 3 for additional information. (b) Alternative revenue programs include the transmission formula rate for PPL Electric, the ECR and DSM programs for LG&E and KU, the GLT program for LG&E, and the generation formula rate for KU. For PPL Electric, the three months ended March 31, 2021 includes a $27 million reserve recorded as a result of a challenge to the transmission formula rate return on equity. See Note 7 for further information. This line item shows the over/under collection of these rate mechanisms with over-collections of revenue shown as positive amounts in the table above and under-collections shown as negative amounts. (c) Represents additional revenues outside the scope of revenues from contracts with customers, such as lease and other miscellaneous revenues.

Mergers, Acquisitions and Dispositions Disclosures | 9. Acquisitions, Development and Divestitures (PPL) Discontinued Operations Share Purchase Agreement to Sell U.K. Utility Business On March 17, 2021, PPL WPD Limited (WPD Limited) entered into a share purchase agreement (WPD SPA) to sell PPL's U.K. utility business to National Grid Holdings One plc (National Grid U.K.), a subsidiary of National Grid plc. Pursuant to the WPD SPA, National Grid U.K. will acquire 100% of the issued share capital of PPL WPD Investments Limited (WPD Investments) for £7.8 billion in cash. WPD Limited will also receive an additional amount of £548,000 for each day during the period from January 1, 2021 to the closing date if the dividends usually declared by WPD Investments to WPD Limited are not paid for that period. The completion of the transaction, which is currently expected to occur by the end of July 2021, is subject to approval by National Grid plc's shareholders and receipt of regulatory approvals from the Financial Conduct Authority (the FCA), the Guernsey Financial Services Commission and, if applicable at the time of closing, from the U.K. Secretary of State in connection with the National Security and Investment Bill 2020. On April 22, 2021, National Grid plc’s shareholders approved the transaction pursuant to the listing rules of the FCA. On May 4, 2021, the Guernsey Financial Services Commission approved the transaction. The approval of the FCA is the sole remaining approval before the transaction can be consummated. WPD Limited and National Grid U.K. have each made customary representations and warranties in the WPD SPA, as well as certain customary covenants by WPD Limited to conduct the businesses that are subject to the WPD SPA in the ordinary course between the execution of the WPD SPA and the closing of the sale. National Grid U.K., at its expense, has purchased warranty and indemnity insurance. The consummation of the transaction is not subject to a financing condition. PPL will not have any significant involvement with the U.K. utility business after completion of the sale. Loss on Sale In connection with entering into the WPD SPA, the U.K. utility business has met the accounting criteria to be classified as assets and liabilities held for sale and discontinued operations beginning with the first quarter of 2021. Accordingly, PPL’s investment in the U.K. utility business has been reported at its estimated fair value, less costs to sell, resulting in an estimated pre-tax loss on sale of $1.6 billion as of March 31, 2021, as determined below. Three Months 2021 Sales proceeds (a) $ 10,806 Costs to sell (b) 48 Carrying value (c) 12,405 Loss on Sale (d) (1,647) (a) Amount represents a contractual selling price of £7.8 billion (a Level 1 fair value measurement) as well as accrued additional consideration of approximately £49 million converted at the March 31, 2021 spot rate of $1.38 per GBP. (b) Estimated amounts incurred for bank advisory, legal and accounting fees to facilitate the transaction. (c) The measurement of PPL’s carrying value of the U.K. utility business includes the realization of accumulated other comprehensive losses of $3.7 billion, which arose primarily from currency translation adjustments and defined benefit plans associated with the U.K. utility business. (d) This loss has been recorded as a reduction to goodwill. Summarized Results of Discontinued Operations The operations of the U.K. utility business are included in "Income (Loss) from Discontinued Operations (net of income taxes)" on the Statements of Income. Following are the components of discontinued operations in the Statements of Income for the periods ended March 31: Three Months 2021 2020 Operating Revenues $ 634 $ 614 Operating Expenses 252 222 Other Income (Expense) - net 66 130 Interest Expense (a) 93 93 Income before income taxes 355 429 Loss on sale (1,647) — Income tax expense (b) 751 79 Income (loss) from Discontinued Operations (net of income taxes) $ (2,043) $ 350 (a) No interest from corporate level debt was allocated to discontinued operations. (b) 2021 primarily includes a federal tax expense of $689 million for the recognition of the tax cost associated with the realization of the book-tax outside basis difference in PPL's investment in the U.K. utility business and foreign tax expense of $73 million on current year operations. Summarized Assets and Liabilities Held for Sale The assets and liabilities of PPL's U.K. utility business at March 31, 2021 and December 31, 2020 are included in "Current assets held for sale" and "Current liabilities held for sale" on PPL's Balance Sheets. The following major classes of assets and liabilities were reclassified on PPL's Balance Sheet as of March 31, 2021 and December 31, 2020: Held for Sale at March 31, 2021 Held for Sale at December 31, 2020 Cash and cash equivalents $ 152 $ 266 Accounts receivable and unbilled revenues 459 389 Price risk management assets 62 146 Property, plant and equipment, net (a) 15,236 14,392 Goodwill (b) 1,029 2,558 Other intangibles 434 413 Pension benefit asset 911 682 Other assets 142 137 Total Assets $ 18,425 $ 18,983 Short-term debt and long-term debt due within one year $ 812 $ 994 Accounts payable 199 220 Customer deposits 240 217 Accrued interest 178 190 Long-term debt 8,297 7,938 Total deferred income taxes 1,123 1,032 Price risk management liabilities 180 137 Other deferred credits and liabilities 347 295 Total Liabilities $ 11,376 $ 11,023 Net assets (c) $ 7,049 $ 7,960 (a) Depreciation of fixed assets ceased upon classification as held for sale.

Accumulated other comprehensive losses related to the U.K. utility business will be reported as a component of PPL’s equity until the sale of the U.K. utility business occurs. Acquisitions Share Purchase Agreement to Acquire The Narragansett Electric Company On March 17, 2021, PPL and its subsidiary, PPL Energy Holdings, entered into a share purchase agreement (Narragansett SPA) with National Grid USA (National Grid U.S.), a subsidiary of National Grid plc to acquire 100% of the outstanding shares of common stock of The Narragansett Electric Company (Narragansett Electric) for approximately $3.8 billion in cash. On May 3, 2021, an Assignment and Assumption Agreement was entered into by PPL, PPL Energy Holdings, PPL Rhode Island Holdings and National Grid U.S. whereby certain interests of PPL Energy Holdings in the Narragansett SPA were assigned to and assumed by PPL Rhode Island Holdings. Pursuant to that Assignment and Assumption Agreement, PPL Rhode Island Holdings became the purchasing entity under the Narragansett SPA. The acquisition is expected to be funded with proceeds from the sale of the U.K. utility business. PPL has agreed to guarantee all obligations of PPL Energy Holdings and PPL Rhode Island Holdings under the Narragansett SPA and the related Assignment and Assumption Agreement. The closing of the acquisition, which is currently expected to occur by March 2022, is subject to the prior closing of the sale of WPD Investments to National Grid U.K. and is also subject to the receipt of certain U.S. regulatory approvals, including, among others, clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, receipt of the approvals, authorizations or waivers from the Rhode Island Division of Public Utilities and Carriers, the FERC and the Massachusetts Department of Public Utilities, as well as other customary conditions to closing, including the execution and delivery of certain related transaction documents. PPL Energy Holdings and PPL Rhode Island Holdings and National Grid U.S. have each made customary representations, warranties and covenants in the Narragansett SPA, including, among others, customary indemnification provisions and covenants by National Grid U.S. to conduct the Narragansett Electric business in the ordinary course between the execution of the Narragansett SPA and the closing of the acquisition. The consummation of the transaction is not subject to a financing condition. In connection with the acquisition, National Grid U.S. and one or more of its subsidiaries and PPL Energy Holdings and/or one or more of its subsidiaries will enter into a transition services agreement, pursuant to which National Grid U.S. and/or one or more of its affiliates will agree to provide certain transition services to Narragansett Electric and its affiliates to facilitate the operation of Narragansett Electric following the consummation of the acquisition and the transition of operations to PPL, as agreed upon in the Narragansett SPA. |

Commitments and Contingencies Disclosure [Abstract] | |
Guarantees | The table below details guarantees provided as of March 31, 2021. Exposure at March 31, 2021 Expiration PPL WPD indemnifications for entities in liquidation and sales of assets $ 11 (a) 2023 WPD guarantee of pension and other obligations of unconsolidated entities 96 (b) LKE Indemnification of lease termination and other divestitures $ 200 (c) 2021 LG&E and KU LG&E and KU obligation of shortfall related to OVEC (d) (a) Indemnification to the liquidators and certain others for existing liabilities or expenses or liabilities arising during the liquidation process. The indemnifications are limited to distributions made from the subsidiary to its parent either prior or subsequent to liquidation or are not explicitly stated in the agreements. The indemnifications generally expire two to seven years subsequent to the date of dissolution of the entities. The exposure noted only includes those cases where the agreements provide for specific limits. In connection with their sales of various businesses, WPD and its affiliates have provided the purchasers with indemnifications that are standard for such transactions, including indemnifications for certain pre-existing liabilities and environmental and tax matters or have agreed to continue their obligations under existing third-party guarantees, either for a set period of time following the transactions or upon the condition that the purchasers make reasonable efforts to terminate the guarantees. Additionally, WPD and its affiliates remain secondarily responsible for lease payments under certain leases that they have assigned to third parties. (b) Relates to certain obligations of discontinued or modified electric associations that were guaranteed at the time of privatization by the participating members. Costs are allocated to the members and can be reallocated if an existing member becomes insolvent. At March 31, 2021, WPD has recorded an estimated discounted liability for which the expected payment/performance is probable. Neither the expiration date nor the maximum amount of potential payments for certain obligations is explicitly stated in the related agreements, and as a result, the exposure has been estimated. (c) LKE provides certain indemnifications covering the due and punctual payment, performance and discharge by each party of its respective obligations. The most comprehensive of these guarantees is the LKE guarantee covering operational, regulatory and environmental commitments and indemnifications made by WKE under a 2009 Transaction Termination Agreement. This guarantee has a term of 12 years ending July 2021, and a maximum exposure of $200 million exclusive of certain items such as government fines and penalties that may exceed the maximum. Additionally, LKE has indemnified various third parties related to historical obligations for other divested subsidiaries and affiliates. The indemnifications vary by entity and the maximum exposures range from being capped at the sale price to no specified maximum. LKE could be required to perform on these indemnifications in the event of covered losses or liabilities being claimed by an indemnified party. LKE cannot predict the ultimate outcomes of the various indemnification scenarios, but does not expect such outcomes to result in significant losses above the amounts recorded. (d) Pursuant to the OVEC power purchase contract, LG&E and KU are obligated to pay for their share of OVEC's excess debt service, post-retirement and decommissioning costs, as well as any shortfall from amounts included within a demand charge designed and expected to cover these costs over the term of the contract. LKE's proportionate share of OVEC's outstanding debt was $103 million at March 31, 2021, consisting of LG&E's share of $71 million and KU's share of $32 million. The maximum exposure and the expiration date of these potential obligations are not presently determinable. See "Energy Purchase Commitments" in Note 11 in PPL's, LKE's, LG&E's and KU's 2020 Form 10-K for additional information on the OVEC power purchase contract. |

Regulatory Matters Kentucky Activities ( PPL, LKE, LG&E and KU ) Rate Case Proceedings On November 25, 2020, LG&E and KU filed requests with the KPSC for an increase in annual electricity and gas revenues of approximately $331 million ($131 million and $170 million in electricity revenues at LG&E and KU and $30 million in gas revenues at LG&E). The revenue increases would be an increase of 11.6% and 10.4% in electricity revenues at LG&E and KU, and an increase of 8.3% in gas revenues at LG&E. In recognition of the economic impact of COVID-19, LG&E and KU requested approval of a one-year billing credit which will credit customers approximately $53 million ($41 million at LG&E and $12 million at KU). The billing credit represents the return to customers of certain regulatory liabilities on LG&E’s and KU’s Balance Sheets and serves to partially mitigate the rate increases during the first year in which the new rates are in effect. LG&E’s and KU’s applications also included a request for a CPCN to deploy Advanced Metering Infrastructure across LG&E’s and KU’s service territories in Kentucky. The applications were based on a forecasted test year of July 1, 2021 through June 30, 2022 and requested an authorized return on equity of 10.0%. On April 19, 2021, LG&E and KU entered into an agreement with all intervening parties to the proceedings resolving all matters in their applications, with the explicit exception of LG&E's and KU's net metering proposals. The agreement proposes increases in annual revenues of $217 million ($77 million and $116 million in electricity revenues at LG&E and KU and $24 million in gas revenues at LG&E) based on an authorized return on equity of 9.55%. The proposal includes an authorized 9.35% return on equity for the ECR and GLT mechanisms. The agreement does not modify the requested one-year billing credit. The agreement proposes that the KPSC should grant LG&E’s and KU’s request for a CPCN to deploy Advanced Metering Infrastructure and proposes the establishment of a Retired Asset Recovery rider (RAR) to provide for recovery of and return on the remaining investment in certain electric generating units upon their retirement over a ten-year period following retirement. In respect of the RAR rider, the agreement proposes that LG&E and KU will continue to use currently approved depreciation rates for Mill Creek units 1 and 2 and Brown Unit 3. The agreement also proposes a four-year “stay-out” commitment from LG&E and KU to refrain from effective base rate increases before July 1, 2025, subject to certain exceptions. A hearing on the agreement, and the underlying proceedings, was completed on April 28, 2021. Subject to KPSC approval, the rates, decreased by the amount of the billing credit, are expected to become effective July 1, 2021. An Order on the net metering issues is expected by the end of September 2021. PPL, LKE, LG&E and KU cannot predict the outcome of these proceedings. Pennsylvania Activities ( PPL and PPL Electric ) Act 129 Act 129 requires Pennsylvania Electric Distribution Companies (EDCs) to meet, by specified dates, specified goals for reduction in customer electricity usage and peak demand. EDCs not meeting the requirements of Act 129 are subject to significant penalties. PPL Electric filed with the PUC its Act 129 Phase IV Energy Efficiency and Conservation Plan (Phase IV Act 129 Plan) on November 30, 2020, for the five-year period starting June 1, 2021 and ending on May 31, 2026. PPL Electric's Phase IV Act 129 Plan was approved by the PUC at its March 25, 2021, public meeting. Federal Matters Challenge to PPL Electric Transmission Formula Rate Return on Equity (PPL and PPL Electric) On May 21, 2020, PP&L Industrial Customer Alliance (PPLICA) filed a complaint with the FERC alleging that PPL Electric's base return on equity (ROE) of 11.18% used to determine PPL Electric's formula transmission rate is unjust and unreasonable, and proposing an alternative ROE of 8.0% based on its interpretation of FERC Opinion No. 569. However, also on May 21, 2020, the FERC issued Opinion No. 569-A in response to numerous requests for rehearing of Opinion No. 569, which revised the method for analyzing base ROE. On June 10, 2020, PPLICA filed a Motion to Supplement the May 21, 2020 complaint in which PPLICA continued to allege that PPL Electric’s base ROE is unjust and unreasonable, but revised its analysis of PPL Electric's base ROE to reflect the guidance provided in Opinion No. 569-A. The amended complaint proposed an updated alternative ROE of 8.5% and also requested that the FERC preserve the original refund effective date as established by the filing of the original complaint on May 21, 2020. Several parties have filed motions to intervene, including one party who filed Comments in Support of the original complaint. On July 10, 2020, PPL Electric filed its Answer and supporting Testimony to the PPLICA filings arguing that the FERC should deny the original and amended complaints as they are without merit and fail to demonstrate the existing base ROE is unjust and unreasonable. In addition, PPL Electric contended any refund effective date should be set for no earlier than June 10, 2020 and PPLICA's proposed replacement ROE should be rejected. On October 15, 2020, the FERC issued an order on the PPLICA complaints which established hearing and settlement procedures, set a refund effective date of May 21, 2020 and granted the motions to intervene. On November 16, 2020, PPL Electric filed a request for rehearing of the portion of the October 15, 2020 Order that set the May 21, 2020 refund effective date. On December 17, 2020, the FERC issued a Notice of Denial of Rehearing by Operation of Law and Providing for Further Consideration. On February 16 and April 19, 2021, PPL Electric filed Petitions for Review with the United States Court of Appeals for the District of Columbia Circuit of the portion of the October 15, 2020 Order that set the May 21, 2020 refund effective date. PPL Electric continues to believe its ROE is just and reasonable and that it has meritorious defenses against the original and amended complaints. Settlement negotiations are currently proceeding, but there can be no assurance that they will result in a final settlement. Although PPL Electric cannot predict the outcome of this matter, in the first quarter of 2021, PPL Electric recorded a revenue reserve of $19 million after-tax. Of this amount, $13 million relates to the period from May 21, 2020 to December 31, 2020. Additional revenue earned from May 21, 2020 through the ultimate resolution of this matter may be subject to refund. A change of 50 basis points to the base ROE would impact PPL Electric's net income by approximately $12 million on an annual basis. FERC Transmission Rate Filing (PPL, LKE, LG&E and KU) In 2018, LG&E and KU applied to the FERC requesting elimination of certain on-going credits to a sub-set of transmission customers relating to the 1998 merger of LG&E's and KU's parent entities and the 2006 withdrawal of LG&E and KU from the Midcontinent Independent System Operator, Inc. (MISO), a regional transmission operator and energy market. The application sought termination of LG&E's and KU's commitment to provide certain Kentucky municipalities mitigation for certain horizontal market power concerns arising out of the 1998 LG&E and KU merger and 2006 MISO withdrawal. The amounts at issue are generally waivers or credits granted to a limited number of Kentucky municipalities for either certain LG&E and KU or MISO transmission charges incurred for transmission service received. Due to the development of robust, accessible energy markets over time, LG&E and KU believe the mitigation commitments are no longer relevant or appropriate. In March 2019, the FERC granted LG&E's and KU's request to remove the ongoing credits, conditioned upon the implementation by LG&E and KU of a transition mechanism for certain existing power supply arrangements, subject to FERC review and approval. In July 2019, LG&E and KU proposed their transition mechanism to the FERC and in September 2019, the FERC rejected the proposed transition mechanism. In September 2020, the FERC issued orders in the rehearing process that modified various aspects of the September 2019 orders which had approved future termination of the credits, including adjusting which customer arrangements are covered by the transition mechanism and respective future periods or dates for termination of credits. In November 2020, the FERC denied the parties' rehearing requests. In November 2020 and January 2021, LG&E and KU and other parties appealed the September 2020 and November 2020 orders at the D.C. Circuit Court of Appeals. The appellate proceedings are continuing, and also include certain additional prior pending petitions for review relating to the matter. On January 15, 2021, LG&E and KU made a filing seeking FERC acceptance of a new proposal for a transition mechanism. On March 16, 2021, the FERC accepted the filed transition mechanism agreements effective on March 17, 2021 but subject to refund, and established hearing and settlement procedures. LG&E and KU are also required to make certain compliance filings consistent with the March 16, 2021 order. LG&E and KU cannot predict the outcome of the respective appellate and FERC proceedings. LG&E and KU currently receive recovery of the waivers and credits provided through other rate mechanisms and such rate recovery would be anticipated to be adjusted consistent with potential changes or terminations of the waivers and credits, as such become effective.
