EXECUTIVE OVERVIEW
Impacts of Severe Winter Weather
In
Storm Restoration Costs
The impact of the severe winter weather resulted in power outages and extensive damage to transmission and distribution infrastructures across the service territories of APCo, KPCo and SWEPCo. As ofJune 30, 2021 , an estimated$65 million of capital expenditures and$144 million of restoration expenses have been incurred related to the severe winter weather. Approximately$138 million of the expenses represent incremental restoration expenses and have been deferred as regulatory assets. The KPSC and LPSC issued orders authorizing the deferral of incremental restoration expenses as regulatory assets. KPCo intends to seek recovery of these incremental storm restoration costs in their next base rate case while APCo and SWEPCo are expected to seek recovery in separate filings. If any of the restoration costs are not recoverable, it could reduce future net income and cash flows and impact financial condition.
Impacts in SPP
The severe winter weather also had a significant impact in SPP resulting in the declaration of Energy Emergency Alert Levels 2 and 3 for the first time in SPP's history. The winter storm increased the demand for natural gas and restricted the available natural gas supply resulting in significantly increased market prices for natural gas power plants to meet reliability needs for the SPP electric system.
Retail Customers
As ofJune 30, 2021 , PSO and SWEPCo have deferred regulatory assets of$669 million and$453 million , respectively, relating to natural gas expenses and purchases of electricity incurred fromFebruary 9, 2021 , toFebruary 20, 2021 , as a result of severe winter weather. SWEPCo's deferred regulatory asset consists of$116 million ,$161 million and$176 million related to theArkansas ,Louisiana andTexas jurisdictions, respectively. PSO and SWEPCo have active fuel clauses that allow for the recovery of prudently incurred fuel and purchased power expenses. Given the significance of these costs, PSO and SWEPCo expect the costs to be subject to prudency reviews. Management believes these costs are probable of future recovery, but expects the recovery period to be extended to mitigate the impact on customer bills. InMarch 2021 , the APSC issued an order authorizing recovery of theArkansas jurisdictional share of the retail customer fuel costs over five years, with the appropriate carrying charge to be determined at a later date. Accordingly, inApril 2021 , SWEPCo began recovery of itsArkansas jurisdictional share of these fuel costs, which are subject to true-up by the APSC. Also inApril 2021 , SWEPCo filed testimony supporting a five-year recovery with a pretax rate of return of 6.05% which has been supported by APSC staff. Various other parties have recommended recovery periods ranging from 5-20 years with a pretax rate of return of 1.65%. InJuly 2021 , the APSC ordered more testimony regarding the option of utilizing securitization to recover the fuel costs. Once testimony concludes, a hearing will be scheduled. The prudency of these fuel costs is expected to be addressed in a separate proceeding. 1 -------------------------------------------------------------------------------- InMarch 2021 , the LPSC approved a special order granting a temporary modification to the FAC that allows SWEPCo to recover theLouisiana jurisdictional share of these retail fuel costs over a longer period than what the FAC traditionally allows. InApril 2021 , SWEPCo began recovery of itsLouisiana jurisdictional share of these fuel costs based on a five year recovery period. SWEPCo will work with the LPSC to finalize the actual recovery period and determine the appropriate carrying charge in future proceedings. InApril 2021 , the OCC approved a waiver for PSO allowing the deferral of the extraordinary fuel and purchase of electricity costs, including carrying costs at an interim rate of 0.75%, over a longer time period than what the FAC traditionally allows. Also inApril 2021 , legislation was enacted inOklahoma to securitize the extraordinary fuel and purchase of electricity costs impacting the utilities within the state. Under the legislation, the OCC has the authority to determine, after receiving an application from a rate-regulated utility, if the extraordinary fuel and purchase of electricity costs incurred inFebruary 2021 may be mitigated through securitization to reduce the impact on customer bills. PSO has filed an application for a financing order to pursue securitization.
SWEPCo expects to make a filing with the PUCT in the third quarter of 2021 to
seek a recovery mechanism and an appropriate carrying charge for the
Wholesale Customers
During the first quarter of 2021, SWEPCo billed wholesale customers$104 million resulting from the severe winter weather events. SWEPCo worked with wholesale customers to establish payment terms for the outstanding accounts receivable. As ofJune 30, 2021 ,$63 million of accounts receivable from wholesale customers are outstanding. Management believes these receivables are probable of future collection.
PSO and SWEPCo Cash Flow Implications
PSO and SWEPCo evaluated financing alternatives to address the timing difference between the payment of the estimated natural gas expenses and purchases of electricity to suppliers and subsequent recovery from customers. InMarch 2021 , PSO drew$100 million on its revolving credit facility and SWEPCo issued$500 million of Senior Unsecured Notes. InMarch 2021 , Parent entered into a$500 million 364-day Term Loan and borrowed the full amount. The proceeds from this loan were used to help fund capital contributions to PSO and SWEPCo totaling$425 million and$100 million , respectively. InApril 2021 , PSO received an additional capital contribution from Parent of$125 million to further address these costs. Although theFebruary 2021 severe winter weather did not materially impact AEP's results of operations for the three and six months endedJune 30, 2021 , if either PSO or SWEPCo is unable to recover these fuel and purchased power costs, or obtain authorization of a reasonable carrying charge on these costs, it could reduce future net income and cash flows and impact financial condition.
COVID-19
In 2020, COVID-19 was declared a pandemic by theWorld Health Organization and theCenters for Disease Control and Prevention . Its rapid spread around the world and throughoutthe United States prompted many countries, includingthe United States , to institute restrictions on travel, public gatherings and certain business operations. These restrictions significantly disrupted economic activity in AEP's service territory and resulted in reduced demand for energy, particularly from commercial and industrial customers. In 2021, weather-normalized customer demand has improved from the pandemic levels experienced in 2020. Management expects continued improvement during the remainder of 2021 as additional vaccinations occur and economic activity improves. During 2020, AEP's electric operating companies informed both retail customers and state regulators that disconnections for non-payment were temporarily suspended. Shortly thereafter, AEP's state regulators also imposed temporary moratoria on customary disconnection practices. As ofJune 30, 2021 , AEP's electric operating companies have resumed customary disconnection practices in all regulated jurisdictions with the exception ofVirginia . AEP continues to work with regulators and stakeholders inVirginia and management currently anticipates resuming customary disconnection practices in the third quarter of 2021. 2 --------------------------------------------------------------------------------
AEP has been and continues to be proactive in engaging with customers to collect payments or establish payment arrangements for outstanding balances. As ofJune 30, 2021 , AEP currently does not expect accounts receivable aging to have a material adverse impact on the Registrants' allowance for uncollectible accounts based on considerations of the COVID-19 impacts and past trends during times of economic instability. Management continues to monitor developments that could have an impact on customer collections. The Registrants continue to take steps to mitigate the potential risks to customers, suppliers and employees posed by the spread of COVID-19. As ofJune 30, 2021 , there has been no material adverse impact to the Registrants' business operations and customer service as a result of the current remote work model. In the second quarter of 2021, management announced a Future of Work model designating employees as: (a) On-Site employees, (b) Hybrid employees and (c) Remote employees. Management currently expects to begin transitioning On-Site employees back to their AEP workplace and Hybrid employees with set schedules back to their AEP workplace inAugust 2021 . Remote employees will begin transitioning back to their AEP workplace inSeptember 2021 on an as-needed basis. Management will continue to review and modify plans as conditions change. In 2021, the Registrants have experienced certain supply chain disruptions driven by several factors including staffing and travel issues caused by the COVID-19 pandemic, the economic recovery from the pandemic, labor shortages and shortages in the availability of certain raw materials. These supply chain disruptions have not had a material impact on the Registrants net income, cash flows and financial condition, but have extended lead times for certain goods and services. Management has implemented risk mitigation strategies in an attempt to mitigate the impacts of these supply chain disruptions. However, a prolonged continuation or a future increase in the severity of supply chain disruptions could impact the cost of certain goods and services and extend lead times which could reduce future net income and cash flows and impact financial condition. Customer Demand AEP's weather-normalized retail sales volumes for the second quarter of 2021 increased by 6.3% from the second quarter of 2020. Weather-normalized residential sales decreased by 3.1% in the second quarter of 2021 from the second quarter of 2020. AEP's second quarter 2021 industrial sales volumes increased by 12.8% compared to the second quarter of 2020. The increase in industrial sales was spread across many industries. Weather-normalized commercial sales increased 10% in the second quarter of 2021 from the second quarter of 2020. AEP's weather-normalized retail sales volumes for the six months endedJune 30, 2021 increased by 1.9% compared to the six months endedJune 30, 2020 . Weather-normalized residential sales decreased by 0.5% for the six months endedJune 30, 2021 compared to the six months endedJune 30, 2020 . AEP's industrial sales volumes for the six months endedJune 30, 2021 increased by 2.8% compared to the six months endedJune 30, 2020 . The recovery in industrial sales volumes was spread across many industries. Weather-normalized commercial sales increased 3.9% for the six months endedJune 30, 2021 compared to the six months endedJune 30, 2020 . The increase in industrial and commercial sales volumes is primarily the result of the COVID-19 pandemic's impact on the second quarter of 2020 when public health restrictions significantly disrupted economic activity and demand for energy in AEP's service territory. Similarly, the decline in weather-normalized residential sales volumes is driven by the cessation of stay at home restrictions that were in place in 2020 and the gradual return of customers to the workplace. 3
--------------------------------------------------------------------------------
Regulatory Matters AEP's public utility subsidiaries are involved in rate and regulatory proceedings at theFERC and their state commissions. Depending on the outcomes, these rate and regulatory proceedings can have a material impact on results of operations, cash flows and possibly financial condition. AEP is currently involved in the following key proceedings. See Note 4 - Rate Matters for additional information. •2017-2019 Virginia Triennial Review - InNovember 2020 , the Virginia SCC issued an order on APCo's 2017-2019 Triennial Review filing concluding that APCo earned above its authorized ROE but within its ROE band for the 2017-2019 period, resulting in no refund to customers and no change to APCo base rates on a prospective basis. The Virginia SCC approved a prospective 9.2% ROE for APCo's 2020-2022 triennial review period with the continuation of a 140 basis point band (8.5% bottom, 9.2% midpoint, 9.9% top). InDecember 2020 , an intervenor filed a petition at the Virginia SCC requesting reconsideration of: (a) the failure of the Virginia SCC to apply a threshold earnings test to the approved regulatory asset for APCo's closed coal-fired generation assets, (b) the Virginia SCC's use of a 2011 benchmark study to measure the replacement value of capacity for purposes of APCo's 2017 - 2019 earnings test and (c) the reasonableness and prudency of APCo's investments in AMI meters. InDecember 2020 , APCo filed a petition at the Virginia SCC requesting reconsideration of: (a) certain issues related to APCo's going-forward rates and (b) the Virginia SCC's decision to deny APCo tariff changes that align rates with underlying costs. For APCo's going-forward rates, APCo requested that the Virginia SCC clarify its final order and clarify whether APCo's current rates will allow it to earn a fair return. If the Virginia SCC's order did conclude on APCo's ability to earn a fair return through existing base rates, APCo further requested that the Virginia SCC clarify whether it has the authority to also permit an increase in base rates. InMarch 2021 , the Virginia SCC issued an order confirming certain of its decisions from theNovember 2020 order and rejecting the various requests for reconsideration from APCo and an intervenor. In confirming its decision to reject an intervenor's recommendation that APCo's AMI costs incurred during the triennial period be disallowed, the Virginia SCC clarified that APCo established the need to replace its existing AMR meters, and that based on the uncertainty surrounding the continued manufacturing and support of AMR technology, APCo reasonably chose to replace them with AMI meters. InMarch 2021 , APCo filed a notice of appeal of the reconsideration order with theVirginia Supreme Court . APCo expects to submit its brief before theVirginia Supreme Court in the third quarter of 2021. InApril 2021 , and in conjunction with APCo'sNovember 2020 andMarch 2021 appeals with theVirginia Supreme Court , APCo filed a petition for interim rates with theVirginia Supreme Court (subject to refund with interest and supported by a bond issuance) requesting a$40 million increase in annual APCo Virginia base rates. APCo submitted this filing based onVirginia law that allows theVirginia Supreme Court to authorize interim rates until the final disposition on APCo's appeals. APCo also requested an expedited schedule from theVirginia Supreme Court on APCo's appeals. InMay 2021 , theVirginia Supreme Court denied APCo's petition for an interim rate increase and denied the request for an expedited schedule on APCo's appeals. APCo ultimately seeks an increase in base rates through its appeal to theVirginia Supreme Court . Among other issues, this appeal includes APCo's request for proper treatment of the closed coal-fired plant assets in APCo's 2017-2019 triennial period, reducing APCo's earnings below the bottom of its authorized ROE band. If APCo's appeals regarding treatment of the closed coal plants are granted by theVirginia Supreme Court , it could initially reduce future net income and impact financial condition. The initial negative impact for the write-off of closed coal-fired plant asset balances would potentially be partially offset by an increase in base rates for earning below APCo's 2017-2019 authorized ROE band. 4 -------------------------------------------------------------------------------- •2020 Ohio Base Rate Case - InJune 2020 , OPCo filed a request with the PUCO for a$42 million annual increase in base rates based upon a proposed 10.15% ROE net of existing riders. InMarch 2021 , OPCo, the PUCO staff and various intervenors filed a joint stipulation and settlement agreement with the PUCO based upon an annual revenue decrease of$68 million and an ROE of 9.7%. The difference between OPCo's requested annual base rate increase and the agreed upon decrease is primarily due to a reduction in the requested ROE, the removal of proposed future energy efficiency costs and a decrease in vegetation management expenses moved to recovery in riders. In addition, the joint stipulation and settlement agreement includes an increased fixed monthly residential customer charge, the discontinuation of rate decoupling and the continuation of the DIR with annual revenue caps of$57 million in 2021,$91 million in 2022,$116 million in 2023 and$51 million for the first five months of 2024. Annual revenue caps for the DIR can be increased if OPCo achieves certain reliability standards. A hearing took place with the PUCO inMay 2021 and initial briefs were filed inJune 2021 followed by reply briefs inJuly 2021 . An order from the PUCO is expected by the end of 2021. •Hurricane Laura - InAugust 2020 , Hurricane Laura hit the coasts ofLouisiana andTexas , causing power outages to more than 130,000 customers across SWEPCo's service territories. Prior to Hurricane Laura, SWEPCo did not have a catastrophe reserve or automatic deferral authority within any of its jurisdictions. InOctober 2020 , the LPSC issued an order allowingLouisiana utilities, including SWEPCo, to establish a regulatory asset to track and defer expenses associated with Hurricane Laura. InOctober 2020 , as part of the 2020 Texas Base Rate Case, SWEPCo requested deferral authority of incremental other operation and maintenance expenses. As ofJune 30, 2021 , management estimates that SWEPCo has incurred incremental other operation and maintenance expenses of$83 million ($81 million of which has been deferred as a regulatory asset related to theLouisiana jurisdiction) and incremental capital expenditures of$30 million , all of which is related to theLouisiana jurisdiction. Management expects to request recovery of these storm costs in a filing inclusive of SWEPCo's various other storm costs. •2012 Texas Base Rate Case - In 2012, SWEPCo filed a request with the PUCT to increase annual base rates primarily due to the completion of the Turk Plant. In 2013, the PUCT issued an order affirming the prudence of the Turk Plant. InJuly 2018 , theTexas Third Court of Appeals reversed the PUCT's judgment affirming the prudence of the Turk Plant and remanded the issue back to the PUCT. InJanuary 2019 , SWEPCo and the PUCT filed petitions for review with theTexas Supreme Court . InMarch 2021 , theTexas Supreme Court issued an opinion reversing theJuly 2018 judgment of theTexas Third Court of Appeals and agreeing with the PUCT's judgment affirming the prudence of the Turk Plant. No parties filed a motion for rehearing with theTexas Supreme Court . As ofJune 30, 2021 , the net book value of Turk Plant was$1.4 billion , before cost of removal, including materials and supplies inventory and CWIP. SWEPCo'sTexas jurisdictional share of the Turk Plant investment is approximately 33%. •InJuly 2019 , Ohio House Bill 6 (HB 6), which offered incentives for power-generating facilities with zero or reduced carbon emissions, was signed into law by theOhio Governor. HB 6 phased out current energy efficiency programs as ofDecember 31, 2020 , including OPCo's shared savings revenues of$26 million annually and renewable mandates after 2026. HB 6 also provided for the recovery of existing renewable energy contracts on a bypassable basis through 2032 and included a provision for recovery of OVEC costs through 2030 which will be allocated to all electric distribution utilities on a non-bypassable basis. OPCo's Inter-Company Power Agreement for OVEC terminates inJune 2040 . InJuly 2020 , an investigation led by theU.S. Attorney's Office resulted in a federal grand jury indictment of the Speaker of theOhio House of Representatives ,Larry Householder , four other individuals, and Generation Now, an entity registered as a 501(c)(4) social welfare organization, in connection with an alleged racketeering conspiracy involving the adoption of HB 6. Certain defendants in that case have since pleaded guilty. InAugust 2020 , an AEP shareholder filed a putative class action lawsuit against AEP and certain of its officers for alleged violations of securities laws in connection with HB 6. OnMay 10, 2021 , the defendants filed a motion to dismiss the securities litigation for failure to state a claim, and under the Court's briefing schedule the motion will be fully briefed byJuly 26, 2021 . In addition, four AEP shareholders have filed derivative actions purporting 5 --------------------------------------------------------------------------------
to assert claims on behalf of AEP against certain AEP officers and directors. See Litigation Related to Ohio House Bill 6 section of Litigation below for additional information.
InMarch 2021 , the Governor ofOhio signed legislation that, among other things, rescinded the payments to the nonaffiliated owner ofOhio's nuclear power plants that were previously authorized under HB 6. The new legislation, House Bill 128, went into effect after 90 days and leaves unchanged other provisions of HB 6 regarding energy efficiency programs, recovery of renewable energy costs and recovery of OVEC costs. To the extent that OPCo is unable to recover the costs of renewable energy contracts on a bypassable basis by the end of 2032, recover costs of OVEC after 2030 or incurs significant costs associated with the securities class action or the derivative actions, it could reduce future net income and cash flows and impact financial condition. •InDecember 2020 , APCo and WPCo filed a proposal with the WVPSC to implement an investment tracker surcharge mechanism for recovering costs associated with capital investment made between base rate cases. The initial filing requests a total annual increase of$50 million ($41 million related to APCo), which represents recovery of costs associated with infrastructure investments made over an approximate three-year period since the companies' last base rate case filing in 2018. The filing also proposes that APCo and WPCo could submit annual filings with requested increases capped to a percentage of total retail revenues (3.5% in the first year and 3% in subsequent filings with an overall cap of 9.5%). If a future base rate case is filed, the surcharge would reset to zero on implementation of the new rates. InJuly 2021 , the WVPSC issued an order approving the investment tracker mechanism with an initial annual revenue requirement of$44 million ($35 million related to APCo) effectiveSeptember 2021 based on a 9.25% ROE. Under the conditions of the order, APCo and WPCo would not be permitted to file a base rate case beforeJune 30, 2024 . The order also allows APCo and WPCo to request future year investment tracker increases for assets placed in service during the most recent 12-month period endingSeptember 30th , subject to an annual three percent rider increase cap on base year total retail revenues. APCo and WPCo filed a petition for reconsideration with the WVPSC to reconsider and modify certain parts of the order, including the condition that APCo and WPCo will not file a base rate case beforeJune 30, 2024 . The companies request certain exceptions to be recognized that allow for base rate case filings in certain circumstances. •InApril 2021 , theFERC issued a supplemental Notice of Proposed Rulemaking (NOPR) proposing to modify its incentive for transmission owners that join RTOs (RTO Incentive). Under the supplemental NOPR, the RTO Incentive would be modified such that a utility would only be eligible for the RTO Incentive for the first three years after the utility joins aFERC-approved Transmission Organization . This is a significant departure from a previous NOPR issued in 2020 seeking to increase the RTO Incentive from 50 basis points to 100 basis points. The supplemental NOPR also required utilities that have received the RTO Incentive for three or more years to submit, within 30 days of the effective date of a final rule, a compliance filing to eliminate the incentive from its tariff prospectively. The supplemental NOPR is subject to a 60 day comment period followed by a 30 day period for reply comments. A final rule could be issued in the fourth quarter of 2021. In 2019, theFERC approved settlement agreements establishing base ROEs of 9.85% (10.35% inclusive of RTO Incentive adder of 0.5%) and 10% (10.5% inclusive of RTO Incentive adder of 0.5%) for AEP's PJM and SPP transmission-owning subsidiaries, respectively. In 2020, theFERC determined the base ROE for MISO's transmission owning subsidiaries should be 10.02% (10.52% inclusive of RTO Incentive adder of 0.5%). InJuly 2021 , theFERC issued an order denyingDayton Power and Light's request for a 50 basis point RTO incentive on the basis that its RTO participation was not voluntary, but rather is required byOhio law. This precedent could have an impact on AEP's transmission owning subsidiaries whose RTO membership is not voluntary, includingOPCo andAEP Ohio Transmission Company . 6 -------------------------------------------------------------------------------- If theFERC modifies its RTO Incentive policy, it would be applied, as applicable, to AEP's PJM, SPP and MISO transmission owning subsidiaries on a prospective basis, and could affect future net income and cash flows and impact financial condition. Based on management's preliminary estimates, if a final rule is adopted consistent with theApril 2021 supplemental NOPR, it could reduce AEP's pretax income by approximately$55 million to$70 million on an annual basis.
Utility Rates and Rate Proceedings
The Registrants file rate cases with their regulatory commissions in order to establish fair and appropriate electric service rates to recover their costs and earn a fair return on their investments. The outcomes of these regulatory proceedings impact the Registrants' current and future results of operations, cash flows and financial position.
The following tables show the Registrants' pending base rate case proceedings in 2021. See Note 4 - Rate Matters for additional information.

Renewable Generation
The growth of AEP's renewable generation portfolio reflects the company's strategy to diversify generation resources to provide clean energy options to customers that meet both their energy and capacity needs.
Contracted Renewable Generation Facilities
AEP continues to develop its renewable portfolio within the Generation & Marketing segment. Activities include working directly with wholesale and large retail customers to provide tailored solutions based upon market knowledge, technology innovations and deal structuring which may include distributed solar, wind, combined heat and power, energy storage, waste heat recovery, energy efficiency, peaking generation and other forms of cost reducing energy technologies. The Generation & Marketing segment also develops and/or acquires large scale renewable generation projects that are backed with long-term contracts with creditworthy counterparties. As ofJune 30, 2021 , subsidiaries within AEP's Generation & Marketing segment had approximately 1,633 MWs of contracted renewable generation projects in-service. In addition, as ofJune 30, 2021 , these subsidiaries had approximately 155 MWs of renewable generation projects under construction with total estimated capital costs of$221 million related to these projects.
Regulated Renewable Generation Facilities
In 2020, PSO received approval from the OCC and SWEPCo received approval from the APSC and LPSC to acquire the North Central Wind Energy Facilities, comprised of threeOklahoma wind facilities totaling 1,485 MWs, on a fixed cost turn-key basis at completion. Both the APSC and LPSC approved the flex-up option, agreeing to acquire theTexas portion, which the PUCT denied. PSO will own 45.5% and SWEPCo will own 54.5% of the project, which will cost approximately$2 billion . InJune 2021 , theIRS issued a notice extending the "Continuity Safe Harbor" deadlines for qualifying renewable energy projects. Under theJune 2021 IRS notice, the Continuity Safe Harbor for qualifying renewable energy projects that began construction in calendar years 2016 through 2019 is extended to six years. Additionally, the Continuity Safe Harbor is extended to five years for qualifying projects that began construction in calendar year 2020. Provided that each facility does satisfy the Continuity Safe Harbor, under the currentIRS guidance, the Sundance wind facility will qualify for 100% of the federal PTC, and the Maverick and Traverse wind facilities will qualify for 80% of the federal PTC. InApril 2021 , PSO and SWEPCo acquired respective undivided ownership interests in the entity that owned Sundance during its development and construction for$270 million , the first of the three NCWF acquisitions. Immediately following the acquisition, PSO and SWEPCo liquidated the entity and simultaneously distributed the Sundance assets in proportion to their undivided ownership interests. Sundance was placed in-service inApril 2021 . The total investment in Sundance is estimated to be$291 million inclusive of previously capitalized pre-construction costs. The Maverick wind facility is targeted to be acquired and placed in-service inDecember 2021 and the Traverse wind facility is targeted to be acquired and placed in-service betweenDecember 2021 andApril 2022 . See Note 6 - Acquisitions for additional information. InJune 2021 , SWEPCo issued requests for proposals to acquire up to 3,000 MWs of wind and 300 MWs of solar generation resources. The wind and solar generation projects would be subject to regulatory approval.
Strategic Evaluation of
AEP has initiated a strategic evaluation for its ownership in KPCo, a wholly-owned regulated generation, transmission and distribution utility with approximately 166,000 retail customers in easternKentucky and KTCo, an AEPTCo wholly-owned regulated transmission only utility. Potential alternatives may include continued ownership or a sale of KPCo and KTCo. Management is currently evaluating the potential alternatives and expects a decision will be made during 2021. As ofJune 30, 2021 , KPCo has total assets of approximately$2.8 billion and total equity of approximately$847 million and KTCo has total assets of approximately$157 million and total equity of approximately$73 million . 8 --------------------------------------------------------------------------------
Racine InFebruary 2021 , AEP signed an agreement to sellRacine to a nonaffiliated party. As ofJune 30, 2021 , the net book value ofRacine was$45 million . The sale ofRacine requires approval from theFERC and theU.S. Army Corps of Engineers . The sale is expected to close in the third quarter of 2021 and result in an immaterial gain.Racine was not presented as Held for Sale on AEP's balance sheets due to immateriality.
DHLC provides 100% of the fuel supply toDolet Hills Power Station . During the second quarter of 2019, theDolet Hills Power Station initiated a seasonal operating schedule. In 2020, management of SWEPCo and CLECO determined DHLC would not proceed developing additionalOxbow Lignite Company (Oxbow) mining areas for future lignite extraction and ceased extraction of lignite at the mine inMay 2020 . Based on these actions, management revised the estimated useful life of DHLC's and Oxbow's assets to coincide with the date at which extraction was discontinued in the second quarter of 2020 and the date at which delivery of lignite is expected to cease inSeptember 2021 . In addition, management also revised the useful life of theDolet Hills Power Station to 2021 based on the remaining estimated fuel supply available for continued seasonal operation. InApril 2020 , SWEPCo and CLECO jointly filed a notification letter to the LPSC providing notice of the cessation of lignite mining.The Dolet Hills Power Station non-fuel costs are recoverable by SWEPCo through base rates. SWEPCo's share of the net investment in theDolet Hills Power Station is$147 million , including CWIP and materials and supplies, before cost of removal. Fuel costs incurred by theDolet Hills Power Station are recoverable by SWEPCo through active fuel clauses. Under the fuel agreements, SWEPCo's fuel inventory and unbilled fuel costs from mining related activities were$119 million as ofJune 30, 2021 . Also, as ofJune 30, 2021 , SWEPCo had a net over-recovered fuel balance of$17 million , excluding impacts of theFebruary 2021 severe winter weather event, which includes fuel consumed at theDolet Hills Power Station . Additional operational, reclamation and other land-related costs incurred by DHLC and Oxbow will be billed to SWEPCo and included in future fuel clauses. InJune 2020 , SWEPCo filed a fuel reconciliation with the PUCT for its retail operations inTexas , includingDolet Hills , for the reconciliation period ofMarch 1, 2017 toDecember 31, 2019 . See "2020 Texas Fuel Reconciliation" section of Note 4 for additional information. InMarch 2021 , the LPSC issued an order allowing SWEPCo to recover up to$20 million of fuel costs in 2021 and defer approximately$30 million of additional costs with a recovery period to be determined at a later date.

Pirkey Power Plant and Related Fuel Operations
In 2020, management announced plans to retire the Pirkey Power Plant in 2023. The Pirkey Power Plant non-fuel costs are recoverable by SWEPCo through base rates and fuel costs are recovered through active fuel clauses. SWEPCo's share of the net investment in the Pirkey Power Plant is$206 million , including CWIP, before cost of removal. Sabine is a mining operator providing mining services to the Pirkey Power Plant. Under the provisions of the mining agreement, SWEPCo is required to pay, as part of the cost of lignite delivered, an amount equal to mining costs plus a management fee. SWEPCo expects fuel deliveries, including billings of all fixed and operating costs, from Sabine to cease during the first quarter of 2023. Under the fuel agreements, SWEPCo's fuel inventory and unbilled fuel costs from mining related activities were$148 million as ofJune 30, 2021 . Also, as ofJune 30, 2021 , SWEPCo had a net over-recovered fuel balance of$17 million , excluding impacts of theFebruary 2021 severe winter weather event, which includes fuel consumed at the Pirkey Power Plant. Additional operational, reclamation and other land-related costs incurred by Sabine will be billed to SWEPCo and included in future fuel clauses. If any of these costs are not recoverable, it could reduce future net income and cash flows and impact financial condition.
LITIGATION
In the ordinary course of business, AEP is involved in employment, commercial, environmental and regulatory litigation. Since it is difficult to predict the outcome of these proceedings, management cannot predict the eventual resolution, timing or amount of any loss, fine or penalty. Management assesses the probability of loss for each contingency and accrues a liability for cases that have a probable likelihood of loss if the loss can be estimated. Adverse results in these proceedings have the potential to reduce future net income and cash flows and impact financial condition. See Note 4 - Rate Matters and Note 5 - Commitments, Guarantees and Contingencies for additional information.
Rockport Plant Litigation
In 2013, theWilmington Trust Company filed a complaint in theU.S. District Court for the Southern District of New York against AEGCo and I&M alleging that it would be unlawfully burdened by the terms of the modified NSR consent decree after the Rockport Plant, Unit 2 lease expiration inDecember 2022 . The terms of the consent decree allow the installation of environmental emission control equipment, repowering, refueling or retirement of the unit. The plaintiffs seek a judgment declaring that the defendants breached the lease, must satisfy obligations related to installation of emission control equipment and indemnify the plaintiffs. TheNew York court granted a motion to transfer this case to theU.S. District Court for the Southern District of Ohio . AEGCo and I&M sought and were granted dismissal by theU.S. District Court for the Southern District of Ohio of certain of the plaintiffs' claims, including claims for compensatory damages, breach of contract, breach of the implied covenant of good faith and fair dealing and indemnification of costs. Plaintiffs voluntarily dismissed the surviving claims that AEGCo and I&M failed to exercise prudent utility practices with prejudice, and the court issued a final judgment. The plaintiffs subsequently filed an appeal in theU.S. Court of Appeals for the Sixth Circuit . In 2017, theU.S. Court of Appeals for the Sixth Circuit issued an opinion and judgment affirming the district court's dismissal of the owners' breach of good faith and fair dealing claim as duplicative of the breach of contract claims, reversing the district court's dismissal of the breach of contract claims and remanding the case for further proceedings. Thereafter, AEP filed a motion with theU.S. District Court for the Southern District of Ohio in the original NSR litigation, seeking to modify the consent decree. The district court granted the owners' unopposed motion to stay the lease litigation to afford time for resolution of AEP's motion to modify the consent decree. The consent decree was modified based on an agreement among the parties inJuly 2019 . The district court's stay of the lease litigation expired inAugust 2020 . Upon expiration of the stay, plaintiffs filed a motion for partial summary judgment, arguing that the consent decree violates the facility lease and the participation agreement and requesting that the district court enter a judgment for the plaintiffs on their breach of contract claim. AEP's memorandum in 10 -------------------------------------------------------------------------------- opposition to plaintiffs' motion for partial summary judgment was filed inOctober 2020 . At the parties' request, the district court stayed the case untilApril 19, 2021 to provide the parties an opportunity to resolve the case. See "Obligations under the New Source Review Litigation Consent Decree" section below for additional information. OnApril 20, 2021 , I&M and AEGCo reached an agreement to acquire 100% of the interests in Rockport Plant, Unit 2 for$115.5 million from certain financial institutions that own the unit through trusts established byWilmington Trust , the nonaffiliated owner trustee of the ownership interests in the unit, with closing to occur as of the end of the Rockport Plant, Unit 2 lease inDecember 2022 . As a result, inMay 2021 , at the parties request, the district court entered a stipulation and order dismissing the case without prejudice to plaintiffs asserting their claims in a re-filed action or a new action. The agreement is subject to customary closing conditions, including regulatory approvals, and as of the closing will result in a final settlement of, and release of claims in, the lease litigation. Management believes its financial statements appropriately reflect the expected resolution of the pending litigation.
Claims Challenging Transition of American Electric Power System Retirement Plan to Cash Balance Formula
The American Electric Power System Retirement Plan (the Plan) has received a letter written on behalf of four participants (the Claimants) making a claim for additional plan benefits and purporting to advance such claims on behalf of a class. When the Plan's benefit formula was changed in the year 2000, AEP provided a special provision for employees hired beforeJanuary 1, 2001 , allowing them to continue benefit accruals under the then benefit formula for a full 10 years alongside of the new cash balance benefit formula then being implemented. Employeeswho were hired on or afterJanuary 1, 2001 accrued benefits only under the new cash balance benefit formula. The Claimants have asserted claims that: (a) the Plan violates the requirements under the Employee Retirement Income Security Act (ERISA) intended to preclude back-loading the accrual of benefits to the end of a participant's career, (b) the Plan violates the age discrimination prohibitions of ERISA and the Age Discrimination in Employment Act and (c) the company failed to provide required notice regarding the changes to the Plan. AEP has responded to the Claimants providing a reasoned explanation for why each of their claims have been denied. The denial of those claims was appealed to the AEP System Retirement Plan Appeal Committee and the Committee upheld the denial of claims. Management will continue to defend against the claims. Management is unable to determine a range of potential losses that is reasonably possible of occurring.
Litigation Related to Ohio House Bill 6 (HB 6)
In 2019,Ohio adopted and implemented HB 6 which benefits OPCo by authorizing rate recovery for certain costs including renewable energy contracts and OVEC's coal-fired generating units. OPCo engaged in lobbying efforts and provided testimony during the legislative process in connection with HB 6. InJuly 2020 , an investigation led by theU.S. Attorney's Office resulted in a federal grand jury indictment of anOhio legislator and associates in connection with an alleged racketeering conspiracy involving the adoption of HB 6. After AEP learned of the criminal allegations against theOhio legislator and others relating to HB 6, the Company, with assistance from outside advisors, conducted a review of the circumstances surrounding the passage of the bill. We do not believe that AEP was involved in any wrongful conduct in connection with the passage of HB 6. InAugust 2020 , an AEP shareholder filed a putative class action lawsuit in theUnited States District Court for the Southern District of Ohio against AEP and certain of its officers for alleged violations of securities laws. The amended complaint alleges misrepresentations or omissions by AEP regarding: (a) its alleged participation in or connection to public corruption with respect to the passage of HB 6 and (b) its regulatory, legislative, political contribution, 501(c)(4) organization contribution and lobbying activities inOhio . The complaint seeks monetary damages, among other forms of relief. OnMay 10, 2021 , the defendants filed a motion to dismiss the securities litigation for failure to state a claim, and under the Court's briefing schedule the motion will be fully briefed byJuly 26, 2021 . The company will continue to defend against the claims. Management is unable to determine a range of potential losses that is reasonably possible of occurring. InJanuary 2021 , an AEP shareholder filed a derivative action in theUnited States District Court for the Southern District of Ohio purporting to assert claims on behalf of AEP against certain AEP officers and directors. InFebruary 2021 , a second AEP shareholder filed a similar derivative action in theCourt of Common Pleas ofFranklin County, Ohio . InApril 2021 , a third AEP shareholder filed a similar derivative action in theU.S. District Court for the Southern District of Ohio and a fourth AEP shareholder filed a similar derivative action in the 11 --------------------------------------------------------------------------------Supreme Court for the State of New York ,Nassau County . These derivative complaints allege the officers and directors made misrepresentations and omissions similar to those alleged in the putative securities class action lawsuit filed against AEP. The derivative complaints together assert claims for: (a) breach of fiduciary duty, (b) waste of corporate assets, (c) unjust enrichment, (d) breach of duty for insider trading and (e) contribution for violations of sections 10(b) and 21D of the Securities Exchange Act of 1934; and seek monetary damages and changes to AEP's corporate governance and internal policies among other forms of relief. The first three derivative actions have been stayed pending the resolution of the motion to dismiss the securities litigation. The fourth has been stayed until such time as the court determines to lift the stay. The company will continue to defend against the claims. Management is unable to determine a range of potential losses that is reasonably possible of occurring. OnMarch 1, 2021 , AEP received a litigation demand letter from counsel representing a purported AEP shareholder. The litigation demand letter is directed to the Board of Directors of AEP and contains factual allegations involving HB 6 that are generally consistent with those in the derivative litigation filed in state and federal court. The letter demands, among other things, that the AEP Board undertake an independent investigation into alleged legal violations by directors and officers, and that, following such investigation, the Company commence a civil action for breaches of fiduciary duty and related claims and take appropriate disciplinary action against those individualswho allegedly harmed the company. The shareholder that sent the letter has agreed that AEP and the AEP Board may defer consideration of the litigation demand until the resolution of the motion to dismiss the securities litigation. The AEP Board will act in response to the letter as appropriate. Management is unable to determine a range of potential losses that is reasonably possible of occurring. InMay 2021 , AEP received a subpoena from theSEC's Division of Enforcement seeking various documents, including documents relating to the benefits to AEP from the passage of HB 6 and documents relating to AEP's financial processes and controls. AEP is cooperating fully with theSEC's subpoena. Although we cannot predict the outcome of theSEC's investigation, we do not believe the results of this inquiry will have a material impact on our financial condition, results of operations, or cash flows. ENVIRONMENTAL ISSUES AEP has a substantial capital investment program and incurs additional operational costs to comply with environmental control requirements. Additional investments and operational changes will be made in response to existing and anticipated requirements to reduce emissions from fossil generation and in response to rules governing the beneficial use and disposal of coal combustion by-products, clean water and renewal permits for certain water discharges. AEP is engaged in litigation about environmental issues, was notified of potential responsibility for the clean-up of contaminated sites and incurred costs for disposal of SNF and future decommissioning of the nuclear units. Management is engaged in the development of possible future requirements including the items discussed below. Management believes that further analysis and better coordination of these environmental requirements would facilitate planning and lower overall compliance costs while achieving the same environmental goals. AEP will seek recovery of expenditures for pollution control technologies and associated costs from customers through rates in regulated jurisdictions. Environmental rules could result in accelerated depreciation, impairment of assets or regulatory disallowances. If AEP cannot recover the costs of environmental compliance, it would reduce future net income and cash flows and impact financial condition.
Environmental Controls Impact on the Generating Fleet
The rules and proposed environmental controls discussed below will have a material impact on AEP System generating units. Management continues to evaluate the impact of these rules, project scope and technology available to achieve compliance. As ofJune 30, 2021 , the AEP System owned generating capacity of approximately 24,700 MWs, of which approximately 12,100 MWs were coal-fired. Management continues to refine the cost estimates of complying with these rules and other impacts of the environmental proposals on fossil generation. Based upon management estimates, AEP's future investment to meet these existing and proposed requirements ranges from approximately$350 million to$700 million through 2027. 12 -------------------------------------------------------------------------------- The cost estimates will change depending on the timing of implementation and whether the FederalEPA provides flexibility in finalizing proposed rules or revising certain existing requirements. The cost estimates will also change based on: (a) potential state rules that impose more stringent standards, (b) additional rulemaking activities in response to court decisions, (c) actual performance of the pollution control technologies installed, (d) changes in costs for new pollution controls, (e) new generating technology developments, (f) total MWs of capacity retired and replaced, including the type and amount of such replacement capacity and (g) other factors. In addition, management continues to evaluate the economic feasibility of environmental investments on regulated and competitive plants.
Obligations under the New Source Review Litigation Consent Decree
In 2007, theU.S. District Court for the Southern District of Ohio approved a consent decree between AEP subsidiaries in the eastern area of the AEP System and theDepartment of Justice , the FederalEPA , eight northeastern states and other interested parties to settle claims that the AEP subsidiaries violated the NSR provisions of the CAA when they undertook various equipment repair and replacement projects over a period of nearly 20 years. The consent decree's terms include installation of environmental control equipment on certain generating units, a declining cap on SO2 and NOX emissions from the AEP System and various mitigation projects. The consent decree has been modified six times, for various reasons, most recently in 2020. All of the environmental control equipment required by the consent decree has been installed.
The CAA establishes a comprehensive program to protect and improve the nation's air quality and control sources of air emissions. The states implement and administer many of these programs and could impose additional or more stringent requirements. The primary regulatory programs that continue to drive investments in AEP's existing generating units include: (a) periodic revisions to NAAQS and the development of SIPs to achieve any more stringent standards, (b) implementation of the regional haze program by the states and the FederalEPA , (c) regulation of hazardous air pollutant emissions under MATS, (d) implementation and review of CSAPR and (e) the FederalEPA 's regulation of greenhouse gas emissions from fossil generation under Section 111 of the CAA. Notable developments in significant CAA regulatory requirements affecting AEP's operations are discussed in the following sections.
National Ambient Air Quality Standards
The FederalEPA periodically reviews and revises the NAAQS for criteria pollutants under the CAA. Revisions tend to increase the stringency of the standards, which in turn may require AEP to make investments in pollution control equipment at existing generating units, or, since most units are already well controlled, to make changes in how units are dispatched and operated. Most recently, the Biden administration has indicated that it is likely to revisit the NAAQS for ozone and PM, which were left unchanged by the prior administration following its review. Management cannot currently predict if any changes to either standard are likely or what such changes may be, but will continue to monitor this issue and any future rulemakings.
Regional Haze
The FederalEPA issued aClean Air Visibility Rule (CAVR) in 2005, which could require power plants and other facilities to install best available retrofit technology to address regional haze in federal parks and other protected areas. CAVR is implemented by the states, through SIPs, or by the FederalEPA , through FIPs. In 2017, the FederalEPA revised the rules governing submission of SIPs to implement the visibility programs, including a provision that postpones the due date for the next comprehensive SIP revisions until 2021. Petitions for review of the final rule revisions have been filed in theU.S. Court of Appeals for the District of Columbia Circuit .
InTexas , the FederalEPA disapproved portions of theTexas regional haze SIP and finalized a FIP that allows participation in the CSAPR ozone season program to satisfy the NOX regional haze obligations for electric 13 -------------------------------------------------------------------------------- generating units inTexas . Additionally, the FederalEPA finalized an intrastate SO2 emissions trading program based on CSAPR allowance allocations. Legal challenges to these various rulemakings are pending in both theU.S. Court of Appeals for the Fifth Circuit and theU.S. Court of Appeals for the District of Columbia Circuit . Management cannot predict the outcome of that litigation, although management supports the intrastate trading program as a compliance alternative to source-specific controls and has intervened in the litigation in support of the FederalEPA .
Cross-State Air Pollution Rule
CSAPR is a regional trading program designed to address interstate transport of emissions that contributed significantly to downwind non-attainment with the 1997 ozone and PM NAAQS. CSAPR relies on SO2 and NOX allowances and individual state budgets to compel further emission reductions from electric utility generating units. Interstate trading of allowances is allowed on a restricted sub-regional basis.
In
Climate Change, CO2 Regulation and Energy Policy
In 2019, the Affordable Clean Energy (ACE) rule established a framework for states to adopt standards of performance for utility boilers based on heat rate improvements for such boilers. However, inJanuary 2021 , theU.S. Court of Appeals for the D.C. Circuit vacated the ACE rule and remanded it to the FederalEPA . Management is unable to predict how the FederalEPA will respond to the court's remand. In 2018, the FederalEPA filed a proposed rule revising the standards for new sources and determined that partial carbon capture and storage is not the best system of emission reduction because it is not available throughout theU.S. and is not cost-effective. That rule has not been finalized. Management continues to actively monitor these rulemaking activities. While no federal regulatory requirements to reduce CO2 emissions are in place, AEP has taken action to reduce and offset CO2 emissions from its generating fleet. AEP expects CO2 emissions from its operations to continue to decline due to the retirement of some of its coal-fired generation units, and actions taken to diversify the generation fleet and increase energy efficiency where there is regulatory support for such activities. The majority of the states where AEP has generating facilities passed legislation establishing renewable energy, alternative energy and/or energy efficiency requirements that can assist in reducing carbon emissions. InApril 2020 ,Virginia enacted clean energy legislation to allow the state to participate in theRegional Greenhouse Gas Initiative, require the retirement of all fossil-fueled generation by 2045 and require 100% renewable energy to be provided toVirginia customers by 2050. Management is taking steps to comply with these requirements, including increasing wind and solar installations, purchasing renewable power and broadening AEP System's portfolio of energy efficiency programs. InFebruary 2021 , AEP announced new intermediate and long-term CO2 emission reduction goals, based on the output of the company's integrated resource plans, which take into account economics, customer demand, grid reliability and resiliency, regulations and the company's current business strategy. The intermediate goal is an 80% reduction from 2000 CO2 emission levels from AEP generating facilities by 2030; the long-term goal is net-zero CO2 emissions from AEP generating facilities by 2050. AEP's total estimated CO2 emissions in 2020 were approximately 44 million metric tons, a 73% reduction from AEP's 2000 CO2 emissions. AEP has made significant progress in reducing CO2 emissions from its power generation fleet and expects its emissions to continue to decline. Technological advances, including energy storage, will determine how quickly AEP can achieve zero emissions while continuing to provide reliable, affordable power for customers. Excessive costs to comply with future legislation or regulations have led to the announcement of early plant closures and could force AEP to close additional coal-fired generation facilities earlier than their estimated useful life. If AEP is unable to recover the costs of its investments, it would reduce future net income and cash flows and impact financial condition. 14 --------------------------------------------------------------------------------
Coal Combustion Residual Rule The FederalEPA 's CCR rule regulates the disposal and beneficial re-use of CCR, including fly ash and bottom ash created from coal-fired generating units and FGD gypsum generated at some coal-fired plants. The rule applies to active and inactive CCR landfills and surface impoundments at facilities of active electric utility or independent power producers. InAugust 2020 , the FederalEPA revised the CCR rule to include a requirement that unlined CCR storage ponds cease operations and initiate closure byApril 11, 2021 . The revised rule provides two options that allow facilities to extend the date by which they must cease receipt of coal ash and close the ponds. The first option provides an extension to cease receipt of CCR no later thanOctober 15, 2023 for most units, andOctober 15, 2024 for a narrow subset of units; however, the FederalEPA 's grant of such an extension will be based upon a satisfactory demonstration of the need for additional time to develop alternative ash disposal capacity and will be limited to the soonest timeframe technically feasible to cease receipt of CCR. Additionally, each request must undergo formal review, including public comments, and be approved by the FederalEPA . AEP filed applications for additional time to develop alternative disposal capacity at the following plants: Generating Projected Company Plant Name and Unit Capacity Net Book Value (a) Retirement Date (in MWs) (in millions) AEGCo Rockport Plant, Unit 1 655 $ 237.1 2028 APCo Amos 2,930 2,128.5 2040 APCo Mountaineer 1,320 966.4 2040 I&M Rockport Plant, Unit 1 655 541.6 (b) 2028 KPCo Mitchell Plant 780 591.9 2040 SWEPCo Flint Creek Plant 258 271.9 2038 WPCo Mitchell Plant 780 594.4 2040 (a)Net book value before cost of removal including CWIP and inventory. (b)Amount includes a$181 million regulatory asset related to the retired Tanners Creek Plant. The IURC and MPSC authorized recovery of theTanners Creek Plant regulatory asset over the useful life of Rockport Plant, Unit 1 in 2015 and 2014, respectively. InDecember 2020 , APCo filed requests with the Virginia SCC and WVPSC to obtain the regulatory approvals necessary to implement CCR and ELG compliance plans and seek recovery of the estimated$240 million investment for the Amos and Mountaineer plants. InJuly 2021 , a Virginia Senior Hearing Examiner recommended that the Virginia SCC deny, at this time, APCo's request for approval of the ELG investments at the Amos and Mountaineer Plants. The judge also recommended that if the Virginia SCC ultimately does not grant APCo approval of the ELG investments, the Virginia SCC should delay consideration of the reasonableness and prudency of previously incurred ELG costs until a future case. Intervenors inVirginia andWest Virginia along with the Virginia Senior Hearing Examiner recommended that only the CCR-related investments be constructed at Amos and Mountaineer, which could cause APCo to close these generating facilities at the end of 2028. If any of APCo's CCR/ELG costs are not approved for recovery, it would reduce future net income and cash flows and impact financial condition. See "APCo and WPCo Rate Matters" section of Note 4 for additional information. InDecember 2020 andFebruary 2021 , WPCo and KPCo filed requests with the WVPSC and KPSC, respectively, to obtain the regulatory approvals necessary to implement CCR and ELG compliance plans and seek recovery of the estimated$132 million investment for the Mitchell Plant that would allow the plant to continue operating through 2040. Within those requests, WPCo and KPCo also filed a$25 million alternative to implement only the CCR-related investments with the WVPSC and KPSC, respectively, which would allow the Mitchell Plant to continue operating only through 2028. InMay 2021 , intervenors inKentucky andWest Virginia submitted testimony with recommendations that only the CCR-related investments be constructed at the Mitchell Plant. InJuly 2021 , the KPSC issued an order approving the CCR only alternative and rejecting the full CCR and ELG compliance plan. As ofJune 30, 2021 , the total of the Mitchell Plant CCR and ELG investment balances in CWIP, was$2 million and$4 million , respectively, split equally between KPCo and WPCo. If any of the CCR and ELG compliance plan costs are not approved for recovery and/or the retirement date of the Mitchell Plant is accelerated to 2028 without 15 --------------------------------------------------------------------------------
commensurate cost recovery, it would reduce future net income and cash flows and impact financial condition. See "KPCo Rate Matters" section of Note 4 for additional information.
The second option is a retirement option, which provides a generating facility an extended operating time without developing alternative CCR disposal. Under the retirement option, a generating facility would have untilOctober 17, 2023 to cease operation and to close CCR storage ponds 40 acres or less in size, or throughOctober 17, 2028 for facilities with CCR storage ponds greater than 40 acres in size. Pursuant to this option, AEP informed the FederalEPA of its intent to retire the Pirkey Power Plant and cease using coal at the Welsh Plant: Accelerated Generating Net Investment Depreciation Projected Company Plant Name and Unit Capacity (a) Regulatory Asset Retirement Date (in MWs) (in millions) SWEPCo Pirkey Power Plant 580$ 157.1 $ 49.4 2023 (b) Welsh Plants, Units SWEPCo 1 and 3 1,053 511.2 24.9 2028 (c)(d) (a)Net book value including CWIP excluding cost of removal and materials and supplies. (b)Pirkey Power Plant is currently being recovered through 2025 in theLouisiana jurisdiction and through 2045 in theArkansas andTexas jurisdictions. (c)InNovember 2020 , management announced it will cease using coal at the Welsh Plant in 2028. (d)Unit 1 is currently being recovered through 2027 in theLouisiana jurisdiction and through 2037 in theArkansas andTexas jurisdictions. Unit 3 is currently being recovered through 2032 in theLouisiana jurisdiction and through 2042 in theArkansas andTexas jurisdictions. AEP may incur significant costs to upgrade or close and replace surface impoundments and landfills used to manage CCR and to conduct any required remedial actions. Under the retirement option above, AEP may need to recover remaining depreciation and estimated closure costs associated with retiring plants over a shorter period. If AEP cannot ultimately recover the costs of environmental compliance and/or the remaining depreciation and estimated closure costs associated with retiring plants in a timely manner, it would reduce future net income and cash flows and impact financial condition. Closure and post-closure costs have been included in ARO in accordance with the requirements in the final rule. Additional ARO revisions will occur on a site-by-site basis if groundwater monitoring activities conclude that corrective actions are required to mitigate groundwater impacts, which could include costs to remove ash from some unlined units. If removal of ash is required without providing similar assurances of cost recovery in regulated jurisdictions, it would impose significant additional operating costs on AEP, which could lead to increased financing costs and liquidity needs. Other units inVirginia, Ohio ,West Virginia andKentucky have already been closed in place in accordance with state law programs. Management will continue to participate in rulemaking activities and make adjustments based on new federal and state requirements affecting its ash disposal units.
Clean Water Act Regulations
The FederalEPA 's ELG rule for generating facilities establishes limits on FGD wastewater, fly ash and bottom ash transport water and flue gas mercury control wastewater, which are to be implemented through each facility's wastewater discharge permit. A recent revision to the ELG rule, published inOctober 2020 , establishes additional options for reusing and discharging small volumes of bottom ash transport water, provides an exception for retiring units and extends the compliance deadline to a date as soon as possible beginning one year after the rule was published but no later thanDecember 2025 . Management has assessed technology additions and retrofits to comply with the rule and the impacts of the FederalEPA 's recent actions on facilities' wastewater discharge permitting for FGD wastewater and bottom ash transport water. Permit modifications for affected facilities were filed inJanuary 2021 that reflect the outcome of that assessment. We continue to work with state agencies to finalize permit terms and conditions. 16 --------------------------------------------------------------------------------
Impact of Environmental Regulation on Coal-Fired Generation
Compliance with extensive environmental regulations requires significant capital investment in environmental monitoring, installation of pollution control equipment, emission fees, disposal costs and permits. Management continuously evaluates cost estimates of complying with these regulations which may result in a decision to retire coal-fired generating facilities earlier than their currently estimated useful lives. Previously, management retired or announced early closure plans for Welsh Unit 2,Oklaunion Power Station ,Dolet Hills Power Station and Northeastern Plant Unit 3.

(i)Welsh Plant, Unit 2 is being recovered over the blended useful life of Welsh Plant, Units 1 and 3. Management is seeking or will seek regulatory recovery, as necessary, for any net book value remaining when the plants are retired. To the extent the net book value of these generation assets are not deemed recoverable, it could materially reduce future net income, cash flows and impact financial condition. 17 --------------------------------------------------------------------------------

The remainder of AEP's activities are presented as Corporate and Other. While not considered a reportable segment, Corporate and Other primarily includes the purchasing of receivables from certain AEP utility subsidiaries, Parent's guarantee revenue received from affiliates, investment income, interest income and interest expense and other nonallocated costs. The following discussion of AEP's results of operations by operating segment includes an analysis of Gross Margin, which is a non-GAAP financial measure. Gross Margin includes Total Revenues less the costs of Fuel and Other Consumables Used for Electric Generation as well as Purchased Electricity for Resale and Amortization of Generation Deferrals as presented in the Registrants' statements of income as applicable. Under the various state utility rate making processes, these expenses are generally reimbursable directly from and billed to customers. As a result, they do not typically impact Operating Income or Earnings Attributable to AEP Common Shareholders. Management believes that Gross Margin provides a useful measure for investors and other financial statement users to analyze AEP's financial performance in that it excludes the effect on Total Revenues caused by volatility in these expenses. Operating Income, which is presented in accordance with GAAP in AEP's statements of income, is the most directly comparable GAAP financial measure to the presentation of Gross Margin. AEP's definition of Gross Margin may not be directly comparable to similarly titled financial measures used by other companies. 18 --------------------------------------------------------------------------------

Liquidity
Liquidity, or access to cash, is an important factor in determining AEP's financial stability. Management believes AEP has adequate liquidity under its existing credit facilities. As ofJune 30, 2021 , AEP had$5 billion of revolving credit facilities to support its commercial paper program. Additional liquidity is available from cash from operations and a receivables securitization agreement. Management is committed to maintaining adequate liquidity. AEP generally uses short-term borrowings to fund working capital needs, property acquisitions and construction until long-term funding is arranged. Sources of long-term funding include issuance of long-term debt, leasing agreements, hybrid securities or common stock. InFebruary 2021 , severe winter weather impacted certain AEP service territories resulting in disruptions to SPP market conditions. InMarch 2021 , AEP entered into a$500 million 364-day Term Loan and borrowed the full amount to help address the cash flow implications resulting from theFebruary 2021 severe winter weather event. See Note 4 - Rate Matters for additional information. Net Available Liquidity

The program funds aUtility Money Pool , which funds AEP's utility subsidiaries; aNonutility Money Pool , which funds certain AEP nonutility subsidiaries; and the short-term debt requirements of subsidiaries that are not participating in either money pool for regulatory or operational reasons, as direct borrowers. The maximum amount of commercial paper outstanding during the first six months of 2021 was$2.5 billion . The weighted-average interest rate for AEP's commercial paper during 2021 was 0.25%. 41 --------------------------------------------------------------------------------
Other Credit Facilities An uncommitted facility gives the issuer of the facility the right to accept or decline each request made under the facility. AEP issues letters of credit on behalf of subsidiaries under six uncommitted facilities totaling$425 million . The Registrants' maximum future payments for letters of credit issued under the uncommitted facilities as ofJune 30, 2021 was$187 million with maturities ranging fromJuly 2021 toJuly 2022 .
Securitized Accounts Receivables
AEP's receivables securitization agreement provides a commitment of
InMarch 2021 , AEP Credit amended its receivables securitization agreement to extend trigger levels established inOctober 2020 and to also provide a step down approach to these levels as management continues to monitor the accounts receivable balances across the affiliated utility subsidiaries in response to the COVID-19 pandemic. InJune 2021 , AEP Credit entered into a waiver for both APCo and SWEPCo to waive certain triggers throughAugust 2021 due to the continuing impact of the COVID-19 pandemic. As ofJune 30, 2021 , the affiliated utility subsidiaries are in compliance with all requirements under the agreement. To the extent that an affiliated utility subsidiary is deemed ineligible under the agreement, the affiliated utility subsidiary would no longer participate in the receivables securitization agreement and the Registrants would need to rely on additional sources of funding for operation and working capital, which may adversely impact liquidity. The receivables that are ineligible under the receivables securitization agreement are financed with short-term debt at AEP Credit.
Debt Covenants and Borrowing Limitations
AEP's credit agreements contain certain covenants and require it to maintain a percentage of debt-to-total capitalization at a level that does not exceed 67.5%. The method for calculating outstanding debt and capitalization is contractually-defined in AEP's credit agreements. Debt as defined in the revolving credit agreement excludes securitization bonds and debt of AEP Credit. As ofJune 30, 2021 , this contractually-defined percentage was 59.7%. Non-performance under these covenants could result in an event of default under these credit agreements. In addition, the acceleration of AEP's payment obligations, or the obligations of certain of AEP's major subsidiaries, prior to maturity under any other agreement or instrument relating to debt outstanding in excess of$50 million , would cause an event of default under these credit agreements. This condition also applies in a majority of AEP's non-exchange-traded commodity contracts and would similarly allow lenders and counterparties to declare the outstanding amounts payable. However, a default under AEP's non-exchange-traded commodity contracts would not cause an event of default under its credit agreements.
The revolving credit facilities do not permit the lenders to refuse a draw on any facility if a material adverse change occurs.
Utility Money Pool borrowings and external borrowings may not exceed amounts authorized by regulatory orders and AEP manages its borrowings to stay within those authorized limits. At-the-Market (ATM) Program AEP participates in an ATM offering program that allows AEP to issue, from time to time, up to an aggregate of$1 billion of its common stock, including shares of common stock that may be sold pursuant to an equity forward sales agreement. As ofJune 30, 2021 , approximately$803 million of equity is available for issuance under the ATM offering program. See Note 12 - Financing Activities for additional information. Equity Units InAugust 2020 , AEP issued 17 million Equity Units initially in the form of corporate units, at a stated amount of$50 per unit, for a total stated amount of$850 million . Net proceeds from the issuance were approximately$833 million . Each corporate unit represents a 1/20 undivided beneficial ownership interest in$1,000 principal amount of AEP's 1.30% Junior Subordinated Notes due in 2025 and a forward equity purchase contract which settles after three years in 2023. The proceeds were used to support AEP's overall capital expenditure plans. 42 -------------------------------------------------------------------------------- InMarch 2019 , AEP issued 16.1 million Equity Units initially in the form of corporate units, at a stated amount of$50 per unit, for a total stated amount of$805 million . Net proceeds from the issuance were approximately$785 million . Each corporate unit represents a 1/20 undivided beneficial ownership interest in$1,000 principal amount of AEP's 3.40% Junior Subordinated Notes due in 2024 and a forward equity purchase contract which settles after three years in 2022. The proceeds from this issuance were used to support AEP's overall capital expenditure plans including the acquisition ofSempra Renewables LLC .
See Note 12 - Financing Activities for additional information.
Dividend Policy and Restrictions
The Board of Directors declared a quarterly dividend of$0.74 per share inJuly 2021 . Future dividends may vary depending upon AEP's profit levels, operating cash flow levels and capital requirements, as well as financial and other business conditions existing at the time. Parent's income primarily derives from common stock equity in the earnings of its utility subsidiaries. Various financing arrangements and regulatory requirements may impose certain restrictions on the ability of the subsidiaries to transfer funds to Parent in the form of dividends. Management does not believe these restrictions will have any significant impact on its ability to access cash to meet the payment of dividends on its common stock. See "Dividend Restrictions" section of Note 12 for additional information. Credit Ratings AEP and its utility subsidiaries do not have any credit arrangements that would require material changes in payment schedules or terminations as a result of a credit downgrade, but its access to the commercial paper market may depend on its credit ratings. In addition, downgrades in AEP's credit ratings by one of the rating agencies could increase its borrowing costs. Counterparty concerns about the credit quality of AEP or its utility subsidiaries could subject AEP to additional collateral demands under adequate assurance clauses under its derivative and non-derivative energy contracts. 43
