Basis of Presentation

These unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements and should be read in conjunction with the consolidated financial statements in the Evergy Companies' combined 2021 Form 10-K.

These unaudited consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary to fairly present the unaudited consolidated financial statements for each of the Evergy Companies for these interim periods. In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Principles of Consolidation

Each of Evergy's, Evergy Kansas Central's and Evergy Metro's unaudited consolidated financial statements includes the accounts of their subsidiaries and variable interest entities (VIEs) of which they are the primary beneficiary. Undivided interests in jointly-owned generation facilities are included on a proportionate basis. Intercompany transactions have been eliminated. The Evergy Companies assess financial performance and allocate resources on a consolidated basis (i.e., operate in one segment).

(a) As of September 30, 2022 and December 31, 2021, represents the planned retirement of Evergy Kansas Central analog meters prior to the end of their remaining useful lives.

Abandoned Plant

When the Evergy Companies retire utility plant, the original cost, net of salvage, is charged to accumulated depreciation. However, when it becomes probable an asset will be retired significantly in advance of its original expected useful life and in the near term, the cost of the asset and related accumulated depreciation is recognized as a separate asset and a probable abandonment. If the asset is still in service, the net amount is classified as plant to be retired, net on the consolidated balance sheets. If the asset is no longer in service, the net amount is classified as a regulatory asset on the consolidated balance sheets.

The Evergy Companies must also assess the probability of full recovery of the remaining net book value of the abandonment. The net book value that may be retained as an asset on the balance sheet for the abandonment is dependent upon amounts that may be recovered through regulated rates, including any return. An impairment charge, if any, would equal the difference between the remaining net book value of the asset and the present value of the future revenues expected from the asset.

Evergy Missouri West retired its Sibley Station in 2018 and the retirement of Sibley Unit 3 met the criteria to be considered an abandonment. Evergy has classified the remaining net book value of Sibley Unit 3 as retired generation facilities within regulatory assets on its consolidated balance sheet and as of December 31, 2021, this amount was $123.4 million. Evergy Missouri West collects a full return of and on its investment in Sibley Station in current customer rates and has requested the continued return of and on its unrecovered investment in Sibley Station as part of its current rate case with the Missouri Public Service Commission (MPSC) which was filed in January 2022.

In October 2019, the MPSC issued an accounting authority order (AAO) requiring Evergy Missouri West to defer to a regulatory liability all revenues collected from customers for return on investment, non-fuel operations and maintenance costs, taxes including accumulated deferred income taxes and all other costs associated with Sibley Station following its retirement in November 2018 to be considered in Evergy Missouri West's current rate case. Subsequent to the MPSC order in 2019, Evergy recorded a regulatory liability for the estimated amount of revenues that Evergy Missouri West had collected from customers for Sibley Station since December 2018 that Evergy determined was probable of refund. This regulatory liability did not include revenues collected related to the return on investment in Sibley Station as Evergy determined that they were not probable of refund based on the relevant facts and circumstances. As of December 31, 2021, this Sibley AAO regulatory liability was $29.3 million.

In the third quarter of 2022, Evergy determined that the refund of revenues collected since December 2018 for return on investment in Sibley Station was now probable based on regulatory precedent from an August 2022 MPSC decision in a similar proceeding for an unaffiliated utility and the MPSC staff’s position in Evergy Missouri West’s current rate case. As a result of this determination, Evergy recorded a $47.5 million decrease to operating revenues on its consolidated statements of comprehensive income for the three months ended and year to date September 30, 2022, for the deferral to its Sibley AAO regulatory liability of revenues collected from customers for return on investment in Sibley Station since December 2018. The Sibley AAO regulatory liability had a total value as of September 30, 2022 of $84.7 million.

Based on the recent MPSC regulatory precedent, Evergy believes it is probable that the Sibley AAO regulatory liability will be offset for recovery purposes against its unrecovered investment in Sibley Unit 3 in its current rate case and as a result, has netted its Sibley AAO regulatory liability against its retired generation facilities regulatory asset for Sibley Unit 3 on its consolidated balance sheets as of September 30, 2022. Year to date September 30, 2022, the retired generation facilities regulatory asset has also been reduced by $7.1 million, primarily consisting of amortization expense equal to the depreciation expense for the asset reflected in retail rates.

Evergy also recorded a $6.0 million estimated impairment loss on Sibley Unit 3 on its consolidated statements of comprehensive income for the three months ended and year to date September 30, 2022, as it no longer expects to earn a return on its unrecovered investment in Sibley Unit 3 based on the regulatory precedent discussed above. As of September 30, 2022, and following the netting of the Sibley AAO regulatory liability, amortization expense and the estimated impairment loss recorded in the third quarter of 2022, Evergy’s retired generation facilities regulatory asset for Sibley Unit 3 was $25.6 million.

The final value of Evergy’s retired generation facilities regulatory asset for Sibley Unit 3 and any impairment loss will be determined by the MPSC in its rate order in Evergy Missouri West’s current rate case, which is currently expected in November 2022, and could differ significantly from the amounts currently recorded. See Note 4 for additional information regarding the AAO and Evergy Missouri West's current rate case.

Other Income (Expense), Net

Year to date September 30, 2022, Evergy's investment earnings (loss) included a pre-tax loss of $16.3 million related to Evergy's equity investment in an early-stage energy solutions company. See "Evergy Equity Investment" in this Note 1 for further information.

The table below shows the detail of other expense for each of the Evergy Companies.

Earnings Per Share

To compute basic earnings per share (EPS), Evergy divides net income attributable to Evergy, Inc. by the weighted average number of common shares outstanding. Diluted EPS includes the effect of issuable common shares resulting from restricted share units (RSUs), restricted stock and a warrant. Evergy computes the dilutive effects of potential issuances of common shares using the treasury stock method or the contingently issuable share method, as applicable.

The following table reconciles Evergy's basic and diluted EPS.

February 2021 Winter Weather Event

In February 2021, much of the central and southern United States, including the service territories of the Evergy Companies, experienced a significant winter weather event that resulted in extremely cold temperatures over a multi-day period (February 2021 winter weather event). These circumstances resulted in higher than normal market

prices within the SPP Integrated Marketplace for both natural gas and power for the duration of the February 2021 winter weather event. As part of the February 2021 winter weather event and inclusive of the aforementioned items, Evergy incurred natural gas and purchased power costs, net of wholesale revenues, of $349.7 million for year to date September 30, 2021. This $349.7 million of net fuel and purchased power costs incurred was primarily driven by $293.4 million of costs at Evergy Missouri West and $127.9 million of costs at Evergy Kansas Central, partially offset by $71.6 million of net wholesale revenues at Evergy Metro.

The amount of purchased power costs incurred and wholesale revenues recorded by the Evergy Companies in the first quarter of 2021 during the February 2021 winter weather event have been subject to subsequent resettlement activity by the SPP that has resulted in net increases to the total cost of the February 2021 winter weather event from the amounts initially recorded. As of September 30, 2022, Evergy has incurred total natural gas and purchased power costs, net of wholesale revenues, of $367.9 million related to the February 2021 winter weather event and inclusive of these subsequent SPP resettlements. This $367.9 million of net fuel and purchased power costs was primarily driven by $296.6 million of costs at Evergy Missouri West and $134.3 million of costs at Evergy Kansas Central, partially offset by $63.0 million of net wholesale revenues at Evergy Metro.

As of September 30, 2022 and December 31, 2021, the Evergy Companies had deferred substantially all of the fuel and purchased power costs, net of wholesale revenues, related to the February 2021 winter weather event to a regulatory asset or liability for recovery or refund through the respective fuel recovery mechanisms of Evergy Kansas Central and Evergy Metro and through a securitization financing order at Evergy Missouri West. See Note 4 for additional information regarding these regulatory proceedings.

The Evergy Companies also engage in limited non-regulated energy marketing activities in various regional power markets that have historically not had a significant impact on the Evergy Companies' results of operations. These energy marketing margins are recorded net in operating revenues on the Evergy Companies' statements of income and comprehensive income. As a result of the elevated market prices experienced in regional power markets across the central and southern United States driven by the February 2021 winter weather event discussed above, Evergy and Evergy Kansas Central recorded $95.0 million of energy marketing margins year to date September 30, 2021, related to the February 2021 winter weather event, primarily driven by activities in the Electric Reliability Council of Texas (ERCOT).

Evergy Equity Investment

From time to time, Evergy makes limited equity investments in early-stage energy solution companies. These investments have historically not had a significant impact on Evergy's results of operations. In October 2021, an equity investment in which Evergy held a minority stake through an initial investment of $3.7 million was acquired through a transaction involving a special purpose acquisition company (SPAC). As a result of its equity investment in the company that was acquired in the SPAC transaction, Evergy received shares of the resulting public company upon the closing of the transaction, which were subject to a restriction on sale for 150 days. The equity investment had a fair value of $31.4 million as of December 31, 2021.

In March 2022, Evergy sold its shares in the equity investment to a financial institution through a share forward agreement following the expiration of the restriction on sale. As part of the share forward agreement, Evergy delivered its shares to the financial institution in exchange for a series of cash settlements totaling $15.1 million based primarily on the volume-weighted average price (VWAP) of the shares over the term of the agreement, which was completed in June 2022. As a result of the completion of the share forward agreement, Evergy no longer has an equity investment in the company.

Year to date September 30, 2022, Evergy recorded a pre-tax loss of $16.3 million in investment earnings (loss) on its consolidated statements of comprehensive income related to the decrease in market value of its equity investment prior to sale and the settlement of the share forward agreement.

Renewable Generation Investment

In August 2022, Evergy Missouri West entered into an agreement with a renewable energy development company to purchase for approximately $250 million an operational wind farm located in the state of Oklahoma with a generating capacity of approximately 199 MW. Subject to customary regulatory approvals and closing conditions, this transaction is expected to close in the first half of 2023.

RATE MATTERS AND REGULATION	9 Months Ended
RATE MATTERS AND REGULATION	Sep. 30, 2022
Regulated Operations [Abstract]
RATE MATTERS AND REGULATION	RATE MATTERS AND REGULATION KCC Proceedings Evergy Kansas Central 2022 Transmission Delivery Charge (TDC) In March 2022, the KCC issued an order adjusting Evergy Kansas Central's retail prices to include updated transmission costs as reflected in the Federal Energy Regulatory Commission (FERC) transmission formula rate (TFR). The new prices were effective in April 2022 and are expected to increase Evergy Kansas Central's annual retail revenues by $20.4 million when compared to 2021. Evergy Metro 2022 TDC In April 2022, the KCC issued an order adjusting Evergy Metro's retail prices to include updated transmission costs as reflected in the FERC TFR. The new prices were effective in May 2022 and are expected to increase Evergy Metro's annual retail revenues by $7.9 million when compared to 2021. Evergy Kansas Central and Evergy Metro Earnings Review and Sharing Plan (ERSP) As part of their merger settlement agreement with the KCC, Evergy Kansas Central and Evergy Metro agreed to participate in an ERSP for the years 2019 through 2022. Under the ERSP, Evergy Kansas Central's and Evergy Metro's Kansas jurisdiction are required to refund to customers 50% of annual earnings in excess of their authorized return on equity of 9.3% to the extent the excess earnings exceed the amount of annual bill credits that Evergy Kansas Central and Evergy Metro agreed to provide in connection with the merger that resulted in the formation of Evergy. Evergy Kansas Central's and Evergy Metro's 2021 calculations of annual earnings did not result in a refund obligation. These calculations were filed with the KCC in March 2022. As of September 30, 2022, Evergy Kansas Central and Evergy Metro estimate their 2022 annual earnings will not result in a refund obligation. The final refund obligations for 2021 and 2022 will be decided by the KCC and could vary from the current estimates. Evergy Kansas Central and Evergy Metro February 2021 Winter Weather Event AAO In February 2021, the KCC issued an emergency AAO directing all Kansas-jurisdictional natural gas and electric utilities, including Evergy Kansas Central and Evergy Metro, to defer to a regulatory asset or regulatory liability any extraordinary costs or revenues, including carrying costs, to provide electric service during the February 2021 winter weather event for consideration in future rate proceedings. Evergy Kansas Central recognized a regulatory asset pursuant to the AAO of approximately $120 million related to its costs incurred during the February 2021 winter weather event, primarily consisting of increased fuel, purchased power, and associated carrying costs. Evergy Metro's Kansas jurisdiction recognized a regulatory liability of approximately $40 million related to its increased wholesale revenues during the February 2021 winter weather event and associated carrying costs. In July 2021, Evergy Kansas Central and Evergy Metro made a joint filing with the KCC regarding the timing and method of recovery or refund for costs and revenues deferred pursuant to the February 2021 winter weather event AAO. In the filing, Evergy Kansas Central and Evergy Metro requested to recover or refund, as appropriate, their deferred February 2021 winter weather event amounts to customers through their fuel recovery mechanisms over two years and one year, respectively, beginning in April 2023. As part of the filing, Evergy Metro also requested a decrease to its February 2021 winter weather event refund to Kansas customers, not currently reflected in its regulatory liability for the February 2021 winter weather event, for jurisdictional allocation differences in its Kansas and Missouri fuel recovery mechanisms. In April 2022, Evergy Kansas Central, Evergy Metro, KCC staff and other intervenors filed a non-unanimous stipulation and agreement with the KCC that resolved all issues regarding the timing and method of recovery for costs and revenues deferred pursuant to the February 2021 winter weather event AAO. As part of the non-unanimous stipulation and agreement, Evergy Kansas Central and Evergy Metro agreed to recover or refund, as appropriate, their deferred February 2021 winter weather amounts to customers through their fuel recovery mechanisms over two years and one year, respectively, beginning in April 2023, and to use the rate of 1.00% to apply carrying charges to these deferred amounts. The non-unanimous stipulation and agreement also permitted Evergy Metro to request the future recovery in its next Kansas rate case of an approximately $5 million under-recovery related to its February 2021 winter weather event refund to Kansas customers for jurisdictional allocation differences in its Kansas and Missouri fuel recovery mechanisms. In June 2022, the KCC issued an order approving the non-unanimous stipulation and agreement. MPSC Proceedings Evergy Metro 2022 Rate Case Proceeding In January 2022, Evergy Metro filed an application with the MPSC to request an increase to its retail revenues of $43.9 million before rebasing fuel and purchased power expense, with a return on equity of 10% and a rate-making equity ratio of 51.19%. The request reflects increases related to higher property taxes and the recovery of infrastructure investments made to improve reliability and enhance customer service and were also partially offset by significant customer savings and cost reductions created since the Great Plains Energy and Evergy Kansas Central merger in 2018. Evergy Metro also requested an additional $3.8 million increase associated with rebasing fuel and purchased power expense as well as the implementation of tracking mechanisms for both property tax expense and credit loss expense and the creation of a storm reserve as part of its application with the MPSC. During the third quarter of 2022, Evergy Metro, MPSC staff and other intervenors in the case reached several non-unanimous partial stipulations and agreements to settle certain issues in the case. The partial stipulations and agreements provide for an increase to Evergy Metro's retail revenues of $25.0 million after rebasing fuel and purchased power expense and are exclusive of certain items which will be resolved by the MPSC in its final order. The resolution of these items could have an impact on the final revenue requirement approved in the case. Evergy Metro also agreed to withdraw its request for the creation of a storm reserve. In September 2022, the MPSC issued an order approving the partial non-unanimous stipulations and agreements. A final order is expected from the MPSC in November 2022 and new rates will be effective in December 2022. Evergy Missouri West 2022 Rate Case Proceeding In January 2022, Evergy Missouri West filed an application with the MPSC to request an increase to its retail revenues of $27.7 million before rebasing fuel and purchased power expense, with a return on equity of 10% and a rate-making equity ratio of 51.81%. The request reflects increases related to higher property taxes and the recovery of infrastructure investments made to improve reliability and enhance customer service and were also partially offset by significant customer savings and cost reductions created since the Great Plains Energy and Evergy Kansas Central merger in 2018. Evergy Missouri West also requested an additional $32.1 million increase associated with rebasing fuel and purchased power expense, the implementation of tracking mechanisms for both property tax expense and credit loss expense, the creation of a storm reserve, and the full return of and return on its unrecovered investment related to the 2018 retirement of Sibley Station as part of its application with the MPSC. During the third quarter of 2022, Evergy Missouri West, MPSC staff and other intervenors in the case reached several non-unanimous partial stipulations and agreements to settle certain issues in the case. The partial stipulations and agreements provide for an increase to Evergy Missouri West's retail revenues of $42.5 million after rebasing fuel and purchased power expense and are exclusive of certain items which will be resolved by the MPSC in its final order, including the return of and return on Evergy Missouri West's unrecovered investment related to the 2018 retirement of Sibley Station, among other items. The resolution of these items could have an impact on the final revenue requirement approved in the case. Evergy Missouri West also agreed to withdraw its request for the creation of a storm reserve. In September 2022, the MPSC issued an order approving the partial non-unanimous stipulations and agreements. A final order is expected from the MPSC in November 2022 and new rates will be effective in December 2022. Evergy Missouri West Other Proceedings In December 2018, the Office of the Public Counsel (OPC) and the Midwest Energy Consumers Group (MECG) filed a petition with the MPSC requesting an AAO that would require Evergy Missouri West to record a regulatory liability for all revenues collected from customers for return on investment, non-fuel operations and maintenance costs, taxes including accumulated deferred income taxes, and all other costs associated with Sibley Station following the station’s retirement in November 2018. In October 2019, the MPSC granted OPC's and MECG's request for an AAO and required Evergy Missouri West to record a regulatory liability for the revenues discussed above for consideration in Evergy Missouri West's current rate case. Subsequent to the MPSC order in 2019, Evergy recorded a regulatory liability for the estimated amount of revenues that Evergy Missouri West had collected from customers for Sibley Station since December 2018 that Evergy had determined was probable of refund. This regulatory liability did not include revenues collected related to the return on investment in Sibley Station as Evergy determined that they were not probable of refund based on the relevant facts and circumstances. As of December 31, 2021, this Sibley AAO regulatory liability was $29.3 million. In the third quarter of 2022, Evergy determined that the refund of revenues collected since December 2018 for return on investment in Sibley Station was now probable based on regulatory precedent from an August 2022 MPSC decision in a similar proceeding for an unaffiliated utility and the MPSC staff’s position in Evergy Missouri West’s current rate case. As a result of this determination, Evergy recorded a $47.5 million deferral to its Sibley AAO regulatory liability for the three months ended and year to date September 30, 2022 for revenues collected from customers for return on investment in Sibley Station since December 2018. The Sibley AAO regulatory liability had a total value as of September 30, 2022 of $84.7 million. Based on the recent MPSC regulatory precedent, Evergy believes that the Sibley AAO regulatory liability will be offset for recovery purposes against its unrecovered investment in Sibley Unit 3 in its current rate case and as a result, has netted its Sibley AAO regulatory liability against its retired generation facilities regulatory asset for Sibley Unit 3 on its consolidated balance sheets as of September 30, 2022, resulting in a net regulatory asset of $25.6 million. The final value and rate treatment of Evergy’s Sibley AAO regulatory liability will be determined by the MPSC in its rate order in Evergy Missouri West’s current rate case, which is currently expected in November 2022, and could differ significantly from the amounts currently recorded. See "Abandoned Plant" in Note 1 for additional information. Evergy Metro and Evergy Missouri West February 2021 Winter Weather Event AAO In June 2021, Evergy Metro and Evergy Missouri West filed a joint request for an AAO with the MPSC that would allow Evergy Metro and Evergy Missouri West to defer to a regulatory asset or regulatory liability any extraordinary costs or revenues, including carrying costs, to provide electric service during the February 2021 winter weather event for consideration in future proceedings. Evergy Metro and Evergy Missouri West initially deferred substantially all of their fuel and purchased power costs, net of wholesale revenues, related to the February 2021 winter weather event to a regulatory asset or liability pursuant to their ability to recover or refund these amounts through their fuel recovery mechanisms, which allow for the recovery or refund of 95% of increases in fuel and purchased power costs, net of wholesale revenues, above the amount included in base rates to customers. This AAO request is intended to address the recovery or refund of the February 2021 winter weather event amounts separate from the normal fuel recovery mechanism process given the extraordinary nature of the February 2021 winter weather event and to help moderate customer bill impacts. Evergy Metro's Missouri jurisdiction recognized a regulatory liability of approximately $25 million related to its increased wholesale revenues during the February 2021 winter weather event. Evergy Missouri West recognized a regulatory asset of approximately $280 million related to its costs incurred during the February 2021 winter weather event, primarily consisting of increased fuel and purchased power costs. In the AAO filing, Evergy Metro requested to refund its deferred February 2021 winter weather event amounts to customers through its fuel recovery mechanism over one year, beginning in April 2022. In the same AAO filing, Evergy Missouri West requested to exclude its deferred February 2021 winter weather event amounts from recovery through its fuel recovery mechanism and indicated its intent to recover them through issuing securitized bonds pursuant to the securitization legislation signed into law in Missouri in July 2021. As part of the filing, Evergy Metro also requested an approximately $5 million decrease to its February 2021 winter weather refund to Missouri customers, which is not currently reflected in its regulatory liability for the February 2021 winter weather event, for jurisdictional allocation differences in its Kansas and Missouri fuel recovery mechanisms and for the portion of net wholesale revenues not traditionally refundable because of the 5% sharing provision of its fuel recovery mechanism. Evergy Missouri West requested an approximately $15 million increase to its February 2021 winter weather event recovery from Missouri customers, which is not currently reflected in its regulatory asset for the February 2021 winter weather event, for the portion of net fuel and purchased power costs not traditionally recoverable because of the 5% sharing provision of its fuel recovery mechanism. In March 2022, the MPSC ordered Evergy Metro in a separate regulatory proceeding to file an adjustment to its fuel recovery mechanism in order to allow its wholesale revenues from the February 2021 winter weather event to be refunded to customers beginning in April 2022. The approximately $5 million decrease to the refund of February 2021 winter weather amounts requested by Evergy Metro due to jurisdictional allocation differences in its Kansas and Missouri fuel recovery mechanisms was not included in the adjustment. In April 2022, the MPSC staff filed a motion to suspend the February 2021 winter weather event AAO procedural schedule for Evergy Metro and Evergy Missouri West pending the resolution of Evergy Missouri West's petition for a securitization financing order discussed below. The MPSC granted the motion to suspend the AAO procedural schedule in April 2022. Evergy Metro began refunding the Missouri portion of its wholesale revenues from the February 2021 winter weather event to customers through its fuel recovery mechanism in April 2022. Evergy Missouri West February 2021 Winter Weather Event Securitization In March 2022, Evergy Missouri West filed a petition for financing order with the MPSC requesting authorization to finance its extraordinary fuel and purchased power costs incurred as part of the February 2021 winter weather event, including carrying costs, through the issuance of securitized bonds. Evergy Missouri West requested to repay the securitized bonds and collect the related amounts from customers over a period of approximately 15 years from the date of issuance of the securitized bonds. In October 2022, the MPSC issued a financing order authorizing Evergy Missouri West to issue securitized bonds to recover its extraordinary fuel and purchased power costs incurred as part of the February 2021 winter weather event. As part of this order, the MPSC found that Evergy Missouri West's costs were prudently incurred, that it should only be allowed to recover 95% of its extraordinary fuel and purchased power costs consistent with the 5% sharing provision of its fuel recovery mechanism, that it should be allowed to recover carrying costs incurred since February 2021 at Evergy Missouri West's long-term debt rate of 5.06% and approved a 15 year repayment period for the bonds with a 17 year legal maturity. In the third quarter of 2022, Evergy Missouri West recorded an increase of $15.0 million to its February 2021 winter weather event regulatory asset for the recovery of carrying charges granted in the MPSC's financing order. As of September 30, 2022, the value of Evergy Missouri West's February 2021 winter weather event regulatory asset was $303.1 million. Evergy Missouri West will continue to record carrying charges on its February 2021 winter weather event regulatory asset until it issues the securitized bonds authorized by the MPSC's financing order, which is currently expected in the first half of 2023. FERC Proceedings In October of each year, Evergy Kansas Central and Evergy Metro post an updated TFR that includes projected transmission capital expenditures and operating costs for the following year. This rate is the most significant component in the retail rate calculation for Evergy Kansas Central's and Evergy Metro's annual request with the KCC to adjust retail prices to include updated transmission costs through the TDC. Evergy Kansas Central TFR In the most recent three years, the updated TFR was expected to adjust Evergy Kansas Central's annual transmission revenues by approximately: •$43.6 million increase effective in January 2023; •$33.2 million increase effective in January 2022; and •$32.4 million increase effective in January 2021. Evergy Metro TFR In the most recent three years, the updated TFR was expected to adjust Evergy Metro's annual transmission revenues by approximately: •$8.6 million increase effective in January 2023; •$18.1 million increase effective in January 2022; and •$3.9 million decrease effective in January 2021.

GOODWILL	9 Months Ended
GOODWILL	Sep. 30, 2022
Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL	GOODWILLGAAP requires goodwill to be tested for impairment annually and when an event occurs indicating the possibility that an impairment exists. Evergy's impairment test for the $2,336.6 million of goodwill that was recorded as a result of the Great Plains Energy and Evergy Kansas Central merger was conducted as of May 1, 2022. The goodwill impairment test consists of comparing the fair value of a reporting unit to its carrying amount, including goodwill, to identify potential impairment. In the event that the carrying amount exceeds the fair value of the reporting unit, an impairment loss is recognized for the difference between the carrying amount of the reporting unit and its fair value. Evergy's consolidated operations are considered one reporting unit for assessment of impairment, as management assesses financial performance and allocates resources on a consolidated basis. The determination of fair value of the reporting unit consisted of two valuation techniques: an income approach consisting of a discounted cash flow analysis and a market approach consisting of a determination of reporting unit invested capital using a market multiple derived from the historical earnings before interest, income taxes, depreciation and amortization and market prices of the stock of peer companies. The results of the two techniques were evaluated and weighted to determine a point within the range that management considered representative of fair value for the reporting unit. The fair value of the reporting unit exceeded the carrying amount, including goodwill. As a result, there was no impairment of goodwill.

PENSION PLANS AND POST-RETIREMENT BENEFITS

Retirement Benefits [Abstract]

PENSION PLANS AND POST-RETIREMENT BENEFITS

Evergy and certain of its subsidiaries maintain, and Evergy Kansas Central and Evergy Metro participate in, qualified non-contributory defined benefit pension plans covering the majority of Evergy Kansas Central's and Evergy Metro's employees as well as certain non-qualified plans covering certain active and retired officers. Evergy is also responsible for its indirect 94% ownership share of Wolf Creek Generating Station's (Wolf Creek) defined benefit plans, consisting of Evergy Kansas South's and Evergy Metro's respective 47% ownership shares.

For the majority of employees, pension benefits under these plans reflect the employees' compensation, years of service and age at retirement. However, for the plan covering Evergy Kansas Central's employees, the benefits for non-union employees hired between 2002 and the second quarter of 2018 and union employees hired beginning in 2012 are derived from a cash balance account formula. The plan was closed to future non-union employees in 2018. For the plans covering Evergy Metro's employees, the benefits for union employees hired beginning in 2014 are derived from a cash balance account formula and the plans were closed to future non-union employees in 2014.

Evergy and its subsidiaries also provide certain post-retirement health care and life insurance benefits for substantially all retired employees of Evergy Kansas Central and Evergy Metro and their respective shares of Wolf Creek's post-retirement benefit plans.

The Evergy Companies record pension and post-retirement expense in accordance with rate orders from the KCC and MPSC that allow the difference between pension and post-retirement costs under GAAP and costs for ratemaking to be recognized as a regulatory asset or liability. This difference between financial and regulatory accounting methods is due to timing and will be eliminated over the life of the plans.

There have been no pension settlement charges for the three months ended and year to date September 30, 2022. For the three months ended and year to date September 30, 2021, Evergy, Evergy Kansas Central and Evergy Metro recorded pension settlement charges of $30.4 million, $22.5 million and $12.5 million, respectively. These settlement charges were the result of accelerated distributions as a result of employee retirements and annuity purchases for certain plan participants. Evergy, Evergy Kansas Central and Evergy Metro deferred substantially all of the charges to a regulatory asset and expect to recover these amounts over future periods pursuant to regulatory agreements.

The following tables provide the components of net periodic benefit costs prior to the effects of capitalization and sharing with joint owners of power plants.

Debt Disclosure [Abstract]

SHORT-TERM BORROWINGS AND SHORT-TERM BANK LINES OF CREDIT

SHORT-TERM BORROWINGS AND SHORT-TERM BANK LINES OF CREDITEvergy's $2.5 billion master credit facility expires in 2026. Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West have borrowing capacity under the master credit facility with specific sublimits for each borrower. These sublimits can be unilaterally adjusted by Evergy for each borrower provided the sublimits remain

within minimum and maximum sublimits as specified in the facility. The applicable interest rates and commitment fees of the facility are subject to upward or downward adjustments, within certain limitations, if Evergy achieves, or fails to achieve, certain sustainability-linked targets based on two key performance indicator metrics: (i) Non-Emitting Generation Capacity and (ii) Diverse Supplier Spend (as defined in the facility).

A default by any borrower under the facility or one of its significant subsidiaries on other indebtedness totaling more than $100.0 million constitutes a default by that borrower under the facility. Under the terms of this facility, each of Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West is required to maintain a total indebtedness to total capitalization ratio, as defined in the facility, of not greater than 0.65 to 1.00 at all times. As of September 30, 2022, Evergy, Evergy Kansas Central, Evergy Metro and Evergy Missouri West were in compliance with this covenant.

The following table summarizes the committed credit facilities (excluding receivable sale facilities discussed in Note 3) available to the Evergy Companies as of September 30, 2022 and December 31, 2021.

The weighted average interest rate for borrowings under the Term Loan Facility as of September 30, 2022, was 3.83%. Evergy's borrowings under the Term Loan Facility were used for, among other things, working capital, capital expenditures and general corporate purposes. The Term Loan Facility contains customary covenants, including one that sets the ratio of maximum allowed total indebtedness to total capitalization of not greater than 0.65 to 1.00, for Evergy and its subsidiaries on a consolidated basis. As of September 30, 2022, Evergy was in compliance with this covenant.

In connection with the establishment of the Evergy Missouri West Mortgage Indenture, Evergy Missouri West issued collateral mortgage bonds secured by the Evergy Missouri West Mortgage Indenture to serve as collateral for Evergy Missouri West's obligations under the following outstanding unsecured senior notes: •$36.0 million of 3.49% Series A, maturing in 2025; •$60.0 million of 4.06% Series B, maturing in 2033; •$150.0 million of 4.74% Series C, maturing in 2043; •$350.0 million of 2.86% Series A, maturing in 2031; •$75.0 million of 3.01% Series B, maturing in 2033; and •$75.0 million of 3.21% Series C, maturing in 2036. The collateral mortgage bonds were issued to the holders of the unsecured senior notes, are only payable if Evergy Missouri West defaults on the underlying unsecured senior notes and do not increase the amount of outstanding debt for Evergy Missouri West. As a result of the above transactions, Evergy Missouri West's outstanding senior notes have effectively become secured by the mortgage lien of the Evergy Missouri West Mortgage Indenture and rank equally and ratably with all of Evergy Missouri West's mortgage bonds, regardless of series, from time to time issued and outstanding under the Evergy Missouri West Mortgage Indenture. Also in March 2022, Evergy Missouri West issued, at a discount, $250.0 million of 3.75% First Mortgage Bonds, maturing in 2032. Senior Notes In March 2022, Evergy Missouri West repaid its $100.0 million of 3.74% Senior Notes at maturity. In June 2022, Evergy repaid its $287.5 million of 5.292% Senior Notes at maturity. Pollution Control Bonds In July 2022, Evergy Metro remarketed its unsecured Series 2008 Environmental Improvement Revenue Refunding (EIRR) bonds maturing in 2038 totaling $23.4 million at a fixed rate of 3.50% through June 30, 2025.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

Values of Financial Instruments

GAAP establishes a hierarchical framework for disclosing the transparency of the inputs utilized in measuring assets and liabilities at fair value. Management's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of assets and liabilities within the fair value hierarchy levels. In addition, the Evergy Companies measure certain investments that do not have a readily determinable fair value at net asset value (NAV), which are not included in the fair value hierarchy. Further explanation of these levels and NAV is summarized below.

Level 1 – Quoted prices are available in active markets for identical assets or liabilities. The types of assets and liabilities included in Level 1 are highly liquid and actively traded instruments with quoted prices, such as equities listed on public exchanges.

Level 2 – Pricing inputs are not quoted prices in active markets but are either directly or indirectly observable. The types of assets and liabilities included in Level 2 are certain marketable debt securities, financial instruments traded in less than active markets or other financial instruments priced with models using highly observable inputs.

Level 3 – Significant inputs to pricing have little or no transparency. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation.

NAV - Investments that do not have a readily determinable fair value are measured at NAV. These investments do not consider the observability of inputs and, therefore, they are not included within the fair value hierarchy. The Evergy Companies include in this category investments in private equity, real estate and alternative investment funds that do not have a readily determinable fair value. The underlying alternative investments include collateralized debt obligations, mezzanine debt and a variety of other investments.

The Evergy Companies record cash and cash equivalents, accounts receivable and short-term borrowings on their consolidated balance sheets at cost, which approximates fair value due to the short-term nature of these instruments.

Fair Value of Long-Term Debt

The Evergy Companies measure the fair value of long-term debt using Level 2 measurements available as of the measurement date. The book value and fair value of the Evergy Companies' long-term debt and long-term debt of variable interest entities is summarized in the following table.



	September 30, 2022				December 31, 2021
	Book Value		Fair Value		Book Value		Fair Value
Long-term debt(a)	(millions)
Evergy(b)	$	9,546.7	$	8,028.1	$	9,687.2	$	10,758.5

Evergy Metro	2,926.1		2,654.4		2,925.0		3,400.8

(a) Includes current maturities.

(b) Book value as of September 30, 2022 and December 31, 2021, includes $93.2 million and $97.9 million, respectively, of fair value adjustments recorded in connection with purchase accounting for the Great Plains Energy and Evergy Kansas Central merger, which are not part of future principal payments and will amortize over the remaining life of the associated debt instrument.

(a)With the exception of investments measured at NAV, fair value is based on quoted market prices of the investments held by the trust and/or valuation models.

(b)Fair value is based on quoted market prices of the investments held by the trust. Debt securities classified as Level 1 are comprised of U.S. Treasury securities. Debt securities classified as Level 2 are comprised of corporate bonds, U.S. Agency, state and local obligations, and other asset-backed securities.

(c)Fair value was based on quoted market prices adjusted for a discount for lack of marketability based on a valuation model due to a restriction on the sale of the stock.

Certain Evergy and Evergy Kansas Central investments included in the table above are measured at NAV as they do not have readily determinable fair values. In certain situations, these investments may have redemption restrictions.

The following table provides additional information on these Evergy and Evergy Kansas Central investments.

Investments in these funds cannot be distributed until the underlying investments have been liquidated, which may take years from the date of initial liquidation. Three funds have begun to make distributions. The initial investment in the fourth and fifth funds occurred in 2016 and 2018, respectively. The fourth fund's term is 15 years, subject to the general partner's right to extend the term for up to three additional one-year periods. The fifth fund's term is 15 years, subject to additional extensions approved by a fund advisory committee to provide for an orderly liquidation of fund investments and dissolution of the fund.

(b)There is a holdback on final redemptions.

The Evergy Companies hold equity and debt investments classified as securities in various trusts including for the purposes of funding the decommissioning of Wolf Creek and for the benefit of certain retired executive officers of Evergy Kansas Central. The Evergy Companies record net realized and unrealized gains and losses on the nuclear decommissioning trusts in regulatory liabilities on their consolidated balance sheets and record net realized and unrealized gains and losses on the Evergy Companies' rabbi trusts in the consolidated statements of income and comprehensive income.

The following table summarizes the net unrealized gains (losses) for the Evergy Companies' nuclear decommissioning trusts and rabbi trusts.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Environmental Matters Set forth below are descriptions of contingencies related to environmental matters that may impact the Evergy Companies' operations or their financial results. Management's assessment of these contingencies, which are based on federal and state statutes and regulations, and regulatory agency and judicial interpretations and actions, has evolved over time. These laws, regulations, interpretations and actions can also change, restrict or otherwise impact the Evergy Companies' operations or financial results. The failure to comply with these laws, regulations, interpretations and actions could result in the assessment of administrative, civil and criminal penalties and the imposition of remedial requirements. The Evergy Companies believe that all of their operations are in substantial compliance with current federal, state and local environmental standards. There are a variety of final and proposed laws and regulations that could have a material adverse effect on the Evergy Companies' operations and consolidated financial results. Due in part to the complex nature of environmental laws and regulations, the Evergy Companies are unable to assess the impact of potential changes that may develop with respect to the environmental contingencies described below. Clean Air Act - Startup, Shutdown and Malfunction (SSM) Regulation In 2015, the Environmental Protection Agency (EPA) issued a final rule addressing how state implementation plans (SIPs) can treat excess emissions during SSM events. This rule was referred to as the 2015 SIP Call Rule. The rule required 36 states to submit SIP revisions by November 2016 to remove certain exemptions and other discretionary enforcement provisions that apply to excess emissions during SSM events. Legal challenges ensued and the case was eventually placed in abeyance. In December 2021, the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) restarted the litigation and oral arguments were held in March 2022. An additional case was also taking place in the U.S. District Court for the Northern District of California (District Court of Northern California) and in June 2022, the District Court of Northern California entered a final consent decree establishing deadlines for the EPA to take final action on SIP revisions that were submitted in response to the 2015 SIP Call Rule. Deadlines for 26 states and air districts, including Kansas, Missouri and Oklahoma, are listed in the final consent decree. Final action from the EPA could result in required SIP revisions in Oklahoma, Kansas and Missouri which could have a material impact on the Evergy Companies. If the D.C. Circuit overturns the EPA's 2015 SIP Call Rule, the final consent decree's deadlines will no longer be valid. Ozone Interstate Transport State Implementation Plans (ITSIP) In 2015, the EPA lowered the Ozone National Ambient Air Quality Standards (NAAQS) from 75 ppb to 70 ppb. Impacted states were required to submit ITSIPs in 2018 to comply with the "Good Neighbor Provisions" of the Clean Air Act (CAA). The EPA did not act on these ITSIP submissions and was challenged in a court filing in May 2021 to address them. In February 2022, the EPA published proposed disapprovals of ITSIPs for nineteen states including Missouri and Oklahoma. In April 2022, the EPA published a final approval of the Kansas ITSIP in the Federal Register. In June 2022, the Missouri Department of Natural Resources (MDNR) announced they intended to submit a supplemental ITSIP to the EPA and placed the document on public notice until August 2022. MDNR anticipates submitting the supplemental ITSIP to the EPA in the fourth quarter of 2022. Ozone Interstate Transport Federal Implementation Plans (ITFIP) In April 2022, the EPA published in the Federal Register the proposed ITFIP to resolve outstanding "Good Neighbor" obligations with respect to the 2015 Ozone NAAQS for 26 states including Missouri and Oklahoma. This ITFIP would establish a revised Cross-State Air Pollution Rule (CSAPR) ozone season nitrogen oxide (NOx) emissions trading program for electric generating units (EGUs), and limit ozone season NOx emissions from certain industrial stationary sources. The proposed rule would also establish a new daily backstop NOx emissions rate limit for applicable coal-fired units larger than 100 MW, as well as unit-specific NOx emission rate limits for certain industrial emission units, and would feature "dynamic" adjustments of emission budgets for EGUs beginning with ozone season 2025. The proposed ITFIP includes reductions to the state ozone season NOx budgets for Missouri and Oklahoma beginning in 2023 with additional reductions in future years. The Evergy Companies provided formal comments as part of the rulemaking process. The EPA intends to issue final ITFIP's for applicable states in March 2023. The EPA is also in the process of reconsidering its December 2020 decisions to retain the Ozone NAAQS at the level set in 2015 and the annual and 24-hour PM2.5 NAAQS at the levels set in 2012. Due to uncertainty regarding the proposed ITFIP and potential lowering of the ozone and PM2.5 NAAQS, the Evergy Companies are unable to accurately assess the impacts of these potential EPA actions on their operations or consolidated financial results, but the cost to comply with the ITFIP and/or a lower future ozone or PM2.5 NAAQS could be material. Regional Haze Rule In 1999, the EPA finalized the Regional Haze Rule which aims to restore national parks and wilderness areas to pristine conditions. The rule requires states in coordination with the EPA, the National Park Service, the U.S. Fish and Wildlife Service, the U.S. Forest Service, and other interested parties to develop and implement air quality protection plans to reduce the pollution that causes visibility impairment. There are 156 "Class I" areas across the U.S. that must be restored to pristine conditions by the year 2064. There are no Class I areas in Kansas, whereas Missouri has two: the Hercules-Glades Wilderness Area and the Mingo Wilderness Area. States must submit revisions to their Regional Haze Rule SIPs every ten years and the first round was due in 2007. For the second ten-year implementation period, the EPA issued a final rule revision in 2017 that allowed states to submit their SIP revisions by July 31, 2021. The Evergy Companies have been in contact with the Kansas Department of Health and Environment (KDHE) and MDNR as they worked to draft their SIP revisions. The Missouri SIP revision does not require any additional reductions from the Evergy Companies' generating units in the state. MDNR submitted the Missouri SIP revision to the EPA in August 2022, however, they failed to do so by the EPA's revised submittal deadline of August 15, 2022. As a result, on August 30, 2022, the EPA published "finding of failure" with respect to Missouri and fourteen other states for failing to submit their Regional Haze SIP revisions by the applicable deadline. This finding of failure established a two-year deadline for the EPA to issue a Regional Haze federal implementation plan (FIP) for each state unless the state submits and the EPA approves a revised SIP that meets all applicable requirements before the EPA issues the FIP. The Kansas SIP revision was placed on public notice in June 2021 and requested no additional emission reductions by electric utilities based on the significant reductions that were achieved during the first implementation period. The EPA provided comments on the Kansas SIP revision in June 2021 that each state is statutorily required to conduct a "four-factor analysis" on at least two sources within the state to help determine if further emission reductions are necessary. The EPA also stated it would be difficult to approve the Kansas SIP revision if at least two four-factor analyses are not conducted on Kansas emission sources. KDHE submitted the Kansas SIP revision in July 2021. If a Kansas generating unit of the Evergy Companies is selected for analysis, the possibility exists that the state or EPA, through a revised SIP or a FIP, could determine that additional operational or physical modifications are required on the generating unit to further reduce emissions. The overall cost of those modifications could be material to the Evergy Companies. Greenhouse Gases Burning coal and other fossil fuels releases carbon dioxide (CO2) and other gases referred to as greenhouse gases (GHG). Various regulations under the CAA limit CO2 and other GHG emissions, and in addition, other measures are being imposed or offered by individual states, municipalities and regional agreements with the goal of reducing GHG emissions. In July 2019, the EPA published the final Affordable Clean Energy (ACE) rule in the Federal Register. This rule contained emission guidelines for GHG emissions from existing electric utility generating units (EGUs) and revisions to emission guideline implementing regulations. The rule defined the "best system of emission reduction" (BSER) for GHG emissions from existing coal-fired EGUs as on-site, heat-rate efficiency improvements. In conjunction with the finalization of the ACE rule, the EPA repealed its previously adopted Clean Power Plan (CPP) on the basis that the EPA had exceeded its statutory authority under CAA section 111(d) by defining BSER through generation shifting. A number of states and industry parties filed petitions for review in the D.C. Circuit, challenging the EPA's repeal of the CPP and its enactment of the ACE rule, and in January 2021, the D.C. Circuit issued a decision holding that CAA section 111(d) could be read in a manner that allows the EPA to define BSER as including generation shifting. The D.C. Circuit therefore vacated both the EPA's repeal of the CPP and its replacement of that rule with the ACE rule, and remanded them to the EPA for further consideration. In October 2021, the Supreme Court granted petitions for certiorari to review the D.C. Circuit decision. The Supreme Court issued its decision in June 2022, reversing the D.C. Circuit's decisions and holding that, absent specific authorization from Congress, the EPA lacks authority to define BSER through generation shifting. Given that the Supreme Court found the CPP to be unlawful and that the deadlines established in the ACE rule have passed, neither rule is in effect following the Supreme Court's ruling. In June 2022, the EPA announced its intent to propose GHG regulations that would apply to EGUs by March 2023. Due to uncertainty regarding the future of the EPA's GHG regulations, the Evergy Companies cannot determine the impacts on their operations or consolidated financial results, but the cost to comply with potential GHG rules could be material. Water The Evergy Companies discharge some of the water used in generation and other operations containing substances deemed to be pollutants. A November 2015 EPA rule applicable to steam-electric power generating plants establishes effluent limitations guidelines (ELG) and standards for wastewater discharges, including limits on the amount of toxic metals and other pollutants that can be discharged. Implementation timelines for this 2015 rule vary from 2018 to 2023. In April 2019, the U.S. Court of Appeals for the 5th Circuit (5th Circuit) issued a ruling that vacated and remanded portions of the original ELG rule. Due to this ruling, the EPA announced a plan in July 2021 to release a proposed rulemaking in the fall of 2022 to address the vacated limitations for legacy wastewater and landfill leachate. Future ELG modifications for the best available technology economically achievable for the discharge of legacy wastewater and landfill leachate are likely and could be material to the Evergy Companies. In October 2020, the EPA published the final ELG reconsideration rule. This rule adjusts numeric limits for flue gas desulfurization (FGD) wastewater and adds a 10% volumetric purge limit for bottom ash transport water. The timeline for final FGD wastewater compliance is as soon as possible on or after one year following publication of the final rule in the Federal Register but no later than December 31, 2025. In August 2021, the EPA published notice in the Federal Register that it is initiating a supplemental rulemaking to revise the ELG regulations after completing review of the ELG reconsideration rule as a result of an executive order from President Biden. As part of the rulemaking process, the EPA will determine if more stringent limitations and standards are appropriate. The 2020 ELG reconsideration rule will remain in effect while the EPA undertakes this new rulemaking. The Evergy Companies have reviewed the 2020 ELG reconsideration regulation, and the costs to comply with these changes are not expected to be material. However, the Evergy Companies cannot predict what revisions the EPA may make under its supplemental rulemaking to revise the ELG regulations, and compliance costs associated with any revisions could be material. In August 2021, based on an order issued by the U.S. District Court for the District of Arizona, which vacated and remanded the EPA's Navigable Waters Protection Rule (NWPR), which was promulgated in 2020, the EPA and the U.S. Army Corps of Engineers announced that they had halted implementation of the NWPR nationwide, and were interpreting "Waters of the United States" consistent with the regulatory regime that was in place prior to 2015. In December 2021, the EPA and the Department of the Army published a proposed rule that would formally repeal the NWPR and revise the definition of “Waters of the United States” to restore the definitions of "Waters of the United States" that were in place prior to 2015. A final rule was expected in August 2022 but has not been issued. The Evergy Companies have reviewed the proposed rule and the impact on their operations or consolidated financial results are not expected to be material. A second rulemaking is expected in the future which will replace the NWPR. The cost to comply with any future rulemaking that replaces the NWPR could be material to the Evergy Companies. Regulation of Coal Combustion Residuals In the course of operating their coal generation plants, the Evergy Companies produce coal combustion residuals (CCRs), including fly ash, gypsum and bottom ash. The EPA published a rule to regulate CCRs in April 2015 that requires additional CCR handling, processing and storage equipment and closure of certain ash disposal units. In January 2022, the EPA published proposed determinations for facilities that filed closure extensions for unlined or clay-lined CCR units. These proposed determinations include various interpretations of the CCR regulations and compliance expectations that may impact all owners of CCR units. These interpretations could require modified compliance plans such as different methods of CCR unit closure. Additionally, more stringent remediation requirements for units that are in corrective action or forced to go into corrective action are possible. In April 2022, the Utility Solid Waste Activities Group (USWAG) and other interested parties filed similar petitions in the D.C. Circuit challenging the EPA's legal positions regarding the CCR rule determinations proposed in January 2022. Some CCR units at Lawrence Energy Center and Sibley Generating Station have moved into corrective action. In January 2022, the EPA issued a "Notice of Potential Violation" to the Tecumseh Energy Center suggesting a closed CCR impoundment should enter corrective action. It is possible that the Tecumseh impoundment or other CCR units at other generation stations could move into corrective action based on the EPA CCR rule interpretations, enforcement actions, or execution of the Evergy Companies' CCR strategy. The cost to comply with these proposed determinations by the EPA could be material. The Evergy Companies have recorded Asset Retirement Obligations (AROs) for their current estimates for the closure of ash disposal ponds and landfills, but the revision of these AROs may be required in the future due to changes in existing CCR regulations, the results of groundwater monitoring of CCR units or changes in interpretation of existing CCR regulations or changes in the timing or cost to close ash disposal ponds and landfills. If revisions to these AROs are necessary, the impact on the Evergy Companies' operations or consolidated financial results could be material.

ORGANIZATION AND BASIS OF PRESENTATION (Policies)	9 Months Ended
ORGANIZATION AND BASIS OF PRESENTATION (Policies)	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements and should be read in conjunction with the consolidated financial statements in the Evergy Companies' combined 2021 Form 10-K. These unaudited consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments necessary to fairly present the unaudited consolidated financial statements for each of the Evergy Companies for these interim periods. In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation Each of Evergy's, Evergy Kansas Central's and Evergy Metro's unaudited consolidated financial statements includes the accounts of their subsidiaries and variable interest entities (VIEs) of which they are the primary beneficiary. Undivided interests in jointly-owned generation facilities are included on a proportionate basis. Intercompany transactions have been eliminated. The Evergy Companies assess financial performance and allocate resources on a consolidated basis (i.e., operate in one segment).
Fuel Inventory and Supplies	Fuel Inventory and SuppliesThe Evergy Companies record fuel inventory and supplies at average cost.
Plant to be Retired, Net	Abandoned Plant When the Evergy Companies retire utility plant, the original cost, net of salvage, is charged to accumulated depreciation. However, when it becomes probable an asset will be retired significantly in advance of its original expected useful life and in the near term, the cost of the asset and related accumulated depreciation is recognized as a separate asset and a probable abandonment. If the asset is still in service, the net amount is classified as plant to be retired, net on the consolidated balance sheets. If the asset is no longer in service, the net amount is classified as a regulatory asset on the consolidated balance sheets. The Evergy Companies must also assess the probability of full recovery of the remaining net book value of the abandonment. The net book value that may be retained as an asset on the balance sheet for the abandonment is dependent upon amounts that may be recovered through regulated rates, including any return. An impairment charge, if any, would equal the difference between the remaining net book value of the asset and the present value of the future revenues expected from the asset. Evergy Missouri West retired its Sibley Station in 2018 and the retirement of Sibley Unit 3 met the criteria to be considered an abandonment. Evergy has classified the remaining net book value of Sibley Unit 3 as retired generation facilities within regulatory assets on its consolidated balance sheet and as of December 31, 2021, this amount was $123.4 million. Evergy Missouri West collects a full return of and on its investment in Sibley Station in current customer rates and has requested the continued return of and on its unrecovered investment in Sibley Station as part of its current rate case with the Missouri Public Service Commission (MPSC) which was filed in January 2022. In October 2019, the MPSC issued an accounting authority order (AAO) requiring Evergy Missouri West to defer to a regulatory liability all revenues collected from customers for return on investment, non-fuel operations and maintenance costs, taxes including accumulated deferred income taxes and all other costs associated with Sibley Station following its retirement in November 2018 to be considered in Evergy Missouri West's current rate case. Subsequent to the MPSC order in 2019, Evergy recorded a regulatory liability for the estimated amount of revenues that Evergy Missouri West had collected from customers for Sibley Station since December 2018 that Evergy determined was probable of refund. This regulatory liability did not include revenues collected related to the return on investment in Sibley Station as Evergy determined that they were not probable of refund based on the relevant facts and circumstances. As of December 31, 2021, this Sibley AAO regulatory liability was $29.3 million. In the third quarter of 2022, Evergy determined that the refund of revenues collected since December 2018 for return on investment in Sibley Station was now probable based on regulatory precedent from an August 2022 MPSC decision in a similar proceeding for an unaffiliated utility and the MPSC staff’s position in Evergy Missouri West’s current rate case. As a result of this determination, Evergy recorded a $47.5 million decrease to operating revenues on its consolidated statements of comprehensive income for the three months ended and year to date September 30, 2022, for the deferral to its Sibley AAO regulatory liability of revenues collected from customers for return on investment in Sibley Station since December 2018. The Sibley AAO regulatory liability had a total value as of September 30, 2022 of $84.7 million. Based on the recent MPSC regulatory precedent, Evergy believes it is probable that the Sibley AAO regulatory liability will be offset for recovery purposes against its unrecovered investment in Sibley Unit 3 in its current rate case and as a result, has netted its Sibley AAO regulatory liability against its retired generation facilities regulatory asset for Sibley Unit 3 on its consolidated balance sheets as of September 30, 2022. Year to date September 30, 2022, the retired generation facilities regulatory asset has also been reduced by $7.1 million, primarily consisting of amortization expense equal to the depreciation expense for the asset reflected in retail rates. Evergy also recorded a $6.0 million estimated impairment loss on Sibley Unit 3 on its consolidated statements of comprehensive income for the three months ended and year to date September 30, 2022, as it no longer expects to earn a return on its unrecovered investment in Sibley Unit 3 based on the regulatory precedent discussed above. As of September 30, 2022, and following the netting of the Sibley AAO regulatory liability, amortization expense and the estimated impairment loss recorded in the third quarter of 2022, Evergy’s retired generation facilities regulatory asset for Sibley Unit 3 was $25.6 million. The final value of Evergy’s retired generation facilities regulatory asset for Sibley Unit 3 and any impairment loss will be determined by the MPSC in its rate order in Evergy Missouri West’s current rate case, which is currently expected in November 2022, and could differ significantly from the amounts currently recorded. See Note 4 for additional information regarding the AAO and Evergy Missouri West's current rate case.
Earnings Per Share	Earnings Per Share To compute basic earnings per share (EPS), Evergy divides net income attributable to Evergy, Inc. by the weighted average number of common shares outstanding. Diluted EPS includes the effect of issuable common shares resulting from restricted share units (RSUs), restricted stock and a warrant. Evergy computes the dilutive effects of potential issuances of common shares using the treasury stock method or the contingently issuable share method, as applicable.

- Definition

Disclosure of inventory accounting policy for inventory classes, including, but not limited to, basis for determining inventory amounts, methods by which amounts are added and removed from inventory classes, loss recognition on impairment of inventories, and situations in which inventories are stated above cost.
