- Definition Carrying amount as of the balance sheet date of capitalized costs of regulated entities that are expected to be recovered through revenue sources within one year or the normal operating cycle, if longer.

If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.

Organization and Basis of Presentation | 1. ORGANIZATION AND BASIS OF PRESENTATION Organization Evergy is a public utility holding company incorporated in 2017 and headquartered in Kansas City, Missouri. Evergy operates primarily through the following wholly-owned direct subsidiaries:
Westar Energy also owns a 50% interest in Prairie Wind Transmission, LLC (Prairie Wind), which is a joint venture between Westar Energy and affiliates of AEP and Berkshire Hathaway Energy Company. Prairie Wind owns a 108-mile, 345 kV double-circuit transmission line that is now being used to provide transmission service in the Southwest Power Pool, Inc. (SPP). Westar Energy accounts for its investment in Prairie Wind under the equity method. Westar Energy and KGE conduct business in their respective service territories using the name Westar Energy. KCP&L and GMO conduct business in their respective service territories using the name KCP&L. Collectively, the Evergy Companies have approximately 12,300 MWs of owned generating capacity and engage in the generation, transmission, distribution and sale of electricity to approximately 1.6 million customers in the states of Kansas and Missouri. Evergy was incorporated in 2017 as Monarch Energy Holding, Inc. (Monarch Energy), a wholly-owned subsidiary of Great Plains Energy Incorporated (Great Plains Energy). Prior to the closing of the merger transactions, Monarch Energy changed its name to Evergy and did not conduct any business activities other than those required for its formation and matters contemplated by the Amended and Restated Agreement and Plan of Merger, dated as of July 9, 2017, by and among Great Plains Energy, Westar Energy, Monarch Energy and King Energy, Inc. (King Energy), a wholly-owned subsidiary of Monarch Energy (Amended Merger Agreement). On June 4, 2018, in accordance with the Amended Merger Agreement, Great Plains Energy merged into Evergy, with Evergy surviving the merger and King Energy merged into Westar Energy, with Westar Energy surviving the merger. These merger transactions resulted in Evergy becoming the parent entity of Westar Energy and the direct subsidiaries of Great Plains Energy, including KCP&L and GMO. See Note 2 for additional information regarding the merger. Principles of Consolidation Westar Energy was determined to be the accounting acquirer in the merger and thus, the predecessor of Evergy. Therefore, Evergy's consolidated financial statements reflect the results of operations of Westar Energy for the three months ended and year to date September 30, 2017 and the financial position of Westar Energy as of December 31, 2017. Evergy had separate operations for the period beginning with the quarter ended June 30, 2018, and references to amounts for periods after the closing of the merger relate to Evergy. The results of Great Plains Energy's direct subsidiaries have been included in Evergy's results of operations from the date of the closing of the merger and thereafter. KCP&L and Westar Energy will continue to maintain their current reporting requirements as Securities and Exchange Commission (SEC) registrants. KCP&L has elected not to apply "push-down accounting" related to the merger, whereby the adjustments of assets and liabilities to fair value and the resulting goodwill would be recorded on the financial statements of the acquired subsidiary. These adjustments for KCP&L, as well as those related to the acquired assets and liabilities of Great Plains Energy and its other direct subsidiaries, are reflected at consolidated Evergy. Each of Evergy's, Westar Energy's and KCP&L's 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). In preparing financial statements that conform to generally accepted accounting principles (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. These unaudited consolidated financial statements have been prepared in accordance with GAAP for the United States of America 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. Because the unaudited consolidated financial statements and notes do not include all of the information and notes required by GAAP for annual financial statements, the unaudited consolidated financial statements and other information included in this quarterly report should be read in conjunction with the Westar Energy First Quarter 2018 Quarterly Report on Form 10-Q, the Great Plains Energy and KCP&L combined First Quarter 2018 Quarterly Report on Form 10-Q, the Westar Energy 2017 Form 10-K and the Great Plains Energy and KCP&L combined 2017 Form 10-K. Certain changes in classification and corresponding reclassification of prior period data were made in Evergy's, Westar Energy's and KCP&L's unaudited consolidated balance sheets, statements of income and comprehensive income and unaudited statements of cash flows for comparative purposes. Evergy reflects the classifications of Westar Energy as the accounting acquirer in the merger. These reclassifications did not affect Evergy's, Westar Energy's or KCP&L's net income or Evergy's, Westar Energy's or KCP&L's cash flows from operations, investing or financing. Most significantly for Westar Energy's consolidated balance sheets as of December 31, 2017 was the reclassification of $50.2 million from accrued employee benefits (currently reported as pension and post-retirement liability) to other long-term liabilities. Most significantly for KCP&L's consolidated balance sheets, current regulatory assets and liabilities have been presented separately from the non-current portions in each respective consolidated balance sheet where recovery or refund is expected within the next 12 months. The table below summarizes KCP&L's reclassifications related to operating and investing activities for its consolidated statement of cash flows for year to date September 30, 2017.
(a)Previously reported within Note 3 to the consolidated financial statements of the Great Plains Energy and KCP&L combined Third Quarter 2017 Quarterly Report on Form 10-Q. Fuel Inventory and Supplies The Evergy Companies record fuel inventory and supplies at average cost. The balances for fuel inventory and supplies are stated separately in the table below.
(a) KCP&L amounts are not included in consolidated Evergy as of December 31, 2017. Property, Plant and Equipment The following tables summarize the property, plant and equipment of Evergy, Westar Energy and KCP&L.
(a) KCP&L amounts are not included in consolidated Evergy as of December 31, 2017. (b) As of September 30, 2018, represents the planned retirement of GMO's Sibley No. 3 Unit and Westar Energy analog meters prior to the end of their remaining useful lives. As of December 31, 2017, represents the planned retirement of Westar Energy analog meters prior to the end of their remaining useful lives. Earnings Per Share Evergy has participating securities in the form of unvested restricted share units (RSUs) with nonforfeitable rights to dividend equivalents that receive dividends on an equal basis with dividends declared on common stock. As a result, Evergy applies the two-class method of computing basic and diluted earnings per share (EPS). To compute basic EPS, Evergy divides the earnings allocated to common stock by the weighted average number of common shares outstanding. Diluted EPS includes the effect of issuable common shares resulting from RSUs with forfeitable rights to dividend equivalents, performance shares and restricted stock. Evergy computes the dilutive effects of potential issuances of common shares using the treasury stock method. The following table reconciles Evergy's basic and diluted EPS.
There were no anti-dilutive securities excluded from the computation of diluted EPS for the three months ended and year to date September 30, 2018 and 2017. Dividends Declared In November 2018, Evergy's Board of Directors (Evergy Board) declared a quarterly dividend of $0.475 per share on Evergy's common stock. The common dividend is payable December 20, 2018, to shareholders of record as of November 29, 2018. In November 2018, Westar Energy's Board of Directors declared a cash dividend payable to Evergy of $70.0 million, payable on December 19, 2018. Supplemental Cash Flow Information
(a) KCP&L amounts are included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018. See Note 2 for the non-cash information related to the merger transaction, including the fair value of Great Plains Energy's assets acquired and liabilities assumed and the issuance of Evergy common stock. New Accounting Standards Intangibles - Internal-Use Software In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for recording implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. An entity in a hosting arrangement that is a service contract will need to determine which project stage (that is, preliminary project stage, application development stage or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are recorded as a prepaid asset depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are incurred. Costs that are recorded to a prepaid asset are to be expensed over the term of the hosting arrangement. The new guidance is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years. The new guidance can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted. The Evergy Companies are currently evaluating the new guidance including the timing of adoption. Compensation - Retirement Benefits In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits, which requires an employer to disaggregate the service cost component from the other components of net benefit cost. The service cost component is to be reported in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The non-service cost components are to be reported separately from service costs and outside of a subtotal of income from operations. The amendments in this update allow only the service cost component to be eligible for capitalization as part of utility plant. The non-service cost components that are no longer eligible for capitalization as part of utility plant will be recorded as a regulatory asset. The new guidance is to be applied retrospectively for the presentation of service cost and non-service cost components in the income statement and prospectively for the capitalization of the service cost component and is effective for interim and annual periods beginning after December 15, 2017. The Evergy Companies adopted ASU No. 2017-07 on January 1, 2018, and accordingly have retrospectively adjusted prior periods. The Evergy Companies utilized the practical expedient that allows for the use of amounts disclosed in Note 7 for applying the retrospective presentation to the 2017 consolidated statements of income and comprehensive income. The following table reflects the retrospective adjustments in the line items of the Evergy Companies' consolidated statements of income and comprehensive income associated with the adoption of ASU No. 2017-07.
(a) KCP&L amounts are not included in consolidated Evergy for the three months ended and year to date September 30, 2017. (b) Certain Evergy, Westar Energy, and KCP&L as previously reported amounts have been adjusted to reflect reclassification adjustments made for comparative purposes as discussed further in Principles of Consolidation above and that have no impact on net income. Statement of Cash Flows In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Among other clarifications, the guidance requires that cash proceeds received from the settlement of corporate-owned life insurance (COLI) policies be classified as cash inflows from investing activities and that cash payments for premiums on COLI policies may be classified as cash outflows for investing activities, operating activities or a combination of both. Retrospective application is required. The Evergy Companies adopted the guidance effective January 1, 2018, which resulted in retrospective reclassification of cash proceeds of $1.9 million from the settlement of COLI policies from cash inflows from operating activities to cash inflows from investing activities for year to date September 30, 2017, for Evergy and Westar Energy. In addition, cash payments of $2.3 million for premiums on COLI policies were reclassified from cash outflows used in operating activities to cash outflows used in investing activities for the same period for Evergy and Westar Energy. The adoption of ASU No. 2016-15 did not have a material impact on KCP&L. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires that the statement of cash flows explains the change for the period of restricted cash and restricted cash equivalents along with cash and cash equivalents. The guidance requires a retrospective transition method and is effective for fiscal years beginning after December 15, 2017. The Evergy Companies adopted the guidance effective January 1, 2018. As a result, Evergy and Westar Energy adjusted amounts previously reported for cash and cash equivalents to include restricted cash which resulted in an increase to beginning and ending cash, cash equivalents and restricted cash of $0.1 million for year to date September 30, 2017. The adoption of ASU No. 2016-18 did not have a material impact on KCP&L. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires an entity that is a lessee to record a right-of-use asset and a lease liability for lease payments on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and requires a modified retrospective transition approach with an option to either adjust or not adjust comparative periods. The Evergy Companies plan to adopt the new guidance on January 1, 2019, without adjusting comparative periods. In 2016, management began evaluating current leases to assess the initial impact on Evergy's consolidated financial results. The Evergy Companies continue to evaluate the guidance and disclosure requirements and believe application of the guidance will result in an increase to the assets and liabilities on their consolidated balance sheets, with minimal impact to their consolidated statements of income and comprehensive income. In addition, management is evaluating the Evergy Companies' internal controls over financial reporting as needed to ensure that they remain effective after implementation. The standard permits an entity to elect a practical expedient for existing or expired contracts to forgo reassessing leases to determine whether each is in scope of the new standard and to forgo reassessing lease classification. The Evergy Companies expect to elect this practical expedient upon implementation. In July 2018, the FASB issued ASU No. 2018-11, which provides entities an optional transition method to apply ASU No. 2016-02 as of the date of initial application of the standard rather than as of the earliest period presented. The Evergy Companies are evaluating this update and have not yet determined if they will elect to use this optional transition method. Financial Instruments In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, which generally requires equity investments to be measured at fair value with changes in fair value recognized in net income. Under the new standard, equity securities are no longer to be classified as available-for-sale or trading securities. The guidance requires a modified retrospective transition method. This guidance is effective for fiscal years beginning after December 15, 2017; accordingly, the Evergy Companies adopted the new standard on January 1, 2018, without a material impact on their consolidated financial statements. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU No. 2014-09 one year, from January 1, 2017, to January 1, 2018. The ASU replaced most existing revenue recognition guidance in GAAP when it became effective. The Evergy Companies adopted ASU No. 2014-09 and its related amendments (ASC 606) on January 1, 2018, using the modified retrospective transition method for all contracts not completed as of the date of adoption. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while historical periods have not been adjusted and continue to be reported in accordance with the legacy guidance in ASC 605 - Revenue Recognition. There was no cumulative effect adjustment to the opening balance of retained earnings in 2018 for the Evergy Companies as a result of the adoption of the new guidance. The impact to both operating revenues and taxes other than income taxes on KCP&L's statements of comprehensive income in 2018 as a result of adopting ASC 606 was a decrease of $22.1 million and $59.7 million for the three months ended and year to date September 30, 2018, respectively. This impact was related to sales taxes and franchise fees collected from KCP&L's Missouri customers, which prior to ASC 606, were recorded gross on KCP&L's statements of comprehensive income. See Note 3 for more information on revenue from contracts with customers. |

Merger of Great Plains Energy and Westar Energy | 2. MERGER OF GREAT PLAINS ENERGY AND WESTAR ENERGY Description of Merger Transaction On June 4, 2018, Evergy completed the mergers contemplated by the Amended Merger Agreement. As a result of the mergers, Great Plains Energy merged into Evergy, with Evergy surviving the merger and King Energy merged into Westar Energy, with Westar Energy surviving the merger. Following the completion of these mergers, Westar Energy and the direct subsidiaries of Great Plains Energy, including KCP&L and GMO, became wholly-owned subsidiaries of Evergy. The merger was structured as a merger of equals in a tax-free exchange of shares that involved no premium paid or received with respect to either Great Plains Energy or Westar Energy. As a result of the closing of the merger transaction, each outstanding share of Great Plains Energy common stock was converted into 0.5981 shares of Evergy common stock and each outstanding share of Westar Energy common stock was converted into 1 share of Evergy common stock. As provided in the Amended Merger Agreement, substantially all of Westar Energy's outstanding equity compensation awards vested and were converted into a right to receive Evergy common stock and all of Great Plains Energy's outstanding equity compensation awards were converted into equivalent Evergy awards subject to the same terms and conditions at the Great Plains Energy merger exchange ratio of 0.5981. Merger Related Regulatory Matters KCC In May 2018, the State Corporation Commission of the State of Kansas (KCC) approved Great Plains Energy's, KCP&L's and Westar Energy's joint application for approval of the merger, including a settlement agreement that had been reached between Great Plains Energy, KCP&L, Westar Energy, KCC staff and certain other intervenors in the case. Through the joint application and settlement agreement, Great Plains Energy, KCP&L and Westar Energy agreed to the conditions and obligations listed below, in addition to other organizational, financing, customer service and civic responsibility commitments.
MPSC In May 2018, the Public Service Commission of the State of Missouri (MPSC) approved Great Plains Energy's, KCP&L's, GMO's and Westar Energy's joint application for approval of the merger, including two stipulations and agreements between these companies, MPSC staff and certain other intervenors in the case. Through the joint application and stipulations and agreements, Great Plains Energy, KCP&L, GMO and Westar Energy agreed to the conditions and obligations listed below, in addition to other organizational, financing, customer service and civic responsibility commitments.
Accounting Charges and Deferrals Related to the Merger The following pre-tax reductions of revenue, expenses and deferral were recognized following the consummation of the merger and are included in the Evergy Companies' consolidated statements of income and comprehensive income for year to date September 30, 2018.
Reductions of revenue and expenses related to customer bill credits, charitable contributions and community support were incurred as a result of conditions in the MPSC and KCC merger orders and were recorded as liabilities in the amounts presented above following the consummation of the merger. Voluntary severance and accelerated equity compensation represent costs related to payments for voluntary severance and change in control plans, as well as the recording of unrecognized equity compensation costs and the incremental fair value associated with the vesting of outstanding Westar Energy equity compensation awards. Other transaction and transition costs include merger success fees and fees for other outside services incurred. Reallocation and deferral of merger transition costs represents the net reallocation of incurred merger transition costs between Evergy, Westar Energy, KCP&L and GMO and the subsequent deferral of these transition costs to a regulatory asset for future recovery in accordance with the KCC and MPSC merger orders. Purchase Price Based on an evaluation of the provisions of ASC 805, Business Combinations, Westar Energy was determined to be the accounting acquirer in the merger. Pursuant to the Amended Merger Agreement, Great Plains Energy's common stock shares were exchanged for Evergy common stock shares at the fixed exchange rate of 0.5981. The total consideration transferred in the merger is based on the closing stock price of Westar Energy on June 4, 2018 and is calculated as follows.
Great Plains Energy's equity compensation awards, including performance shares and restricted stock, were replaced by equivalent Evergy equity compensation awards subject to substantially the same terms and conditions upon the closing of the merger. In accordance with the accounting guidance in ASC 805, a portion of the fair value of these awards is attributable to the purchase price as it represents consideration transferred in the merger. Purchase Price Allocation The fair value of Great Plains Energy's assets acquired and liabilities assumed as of June 4, 2018 was determined based on significant estimates and assumptions that are judgmental in nature. Third-party valuation specialists were engaged to assist in the valuation of these assets and liabilities. The fair values of Great Plains Energy's assets acquired and liabilities assumed utilized for the purchase price allocation are preliminary to the extent that additional information is obtained about facts and circumstances that existed as of the acquisition date. The significant assets and liabilities for which preliminary valuation amounts are reflected as of the filing of this combined Form 10-Q include the fair value of acquired long-term debt, asset retirement obligations, pension and post-retirement plans, accumulated deferred income tax liabilities and certain other long-term assets and liabilities. The majority of Great Plains Energy's operations are subject to the rate-setting authority of the MPSC, KCC and The Federal Energy Regulatory Commission (FERC) and are accounted for pursuant to GAAP, including the accounting guidance for regulated operations. The rate-setting and cost recovery provisions for Great Plains Energy's regulated operations provide revenue derived from costs including a return on investment of assets and liabilities included in rate base. Except for the significant assets and liabilities for which valuation adjustments were made as discussed above, the fair values of Great Plains Energy's tangible and intangible assets and liabilities subject to these rate-setting provisions approximate their carrying values and the assets and liabilities do not reflect any adjustments to these amounts other than for amounts not included in rate base. The difference between the fair value and pre-merger carrying amounts for Great Plains Energy's long-term debt, asset retirement obligations and pension and post-retirement plans that were related to regulated operations were recorded as a regulatory asset or liability. The excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed was recognized as goodwill as of the merger date. The preliminary purchase price allocation to Great Plains Energy's assets and liabilities as of June 4, 2018 is detailed in the following table.
Impact of Merger The impact of Great Plains Energy's subsidiaries on Evergy's revenues in the consolidated statements of income for the three months ended and year to date September 30, 2018 was an increase of $817.6 million and $1,060.2 million, respectively. The impact of Great Plains Energy's subsidiaries on Evergy's net income attributable to Evergy in the consolidated statements of income for the three months ended and year to date September 30, 2018 was an increase of $178.8 million and $239.0 million, respectively. Evergy has incurred total merger-related costs, including reductions of revenue for customer bill credits, of $10.3 million and $134.3 million for the three months ended and year to date September 30, 2018, respectively, and $7.9 million and $8.9 million for the three months ended and year to date September 30, 2017, respectively. Pro Forma Financial Information The following unaudited pro forma financial information reflects the consolidated results of operations of Evergy as if the merger transactions had taken place on January 1, 2017. The unaudited pro forma information was calculated after applying Evergy's accounting policies and adjusting Great Plains Energy's results to reflect purchase accounting adjustments. The unaudited pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the consolidated results of operations that would have been achieved or the future consolidated results of operations of Evergy.
Evergy, Westar Energy and Great Plains Energy incurred non-recurring costs directly related to the merger that have been excluded in the pro forma earnings presented above. After-tax non-recurring merger-related costs incurred by Evergy, Westar Energy and Great Plains Energy were $5.2 million and $73.4 million for the three months ended and year to date September 30, 2018, respectively, and $6.0 million and $9.4 million for the three months ended and year to date September 30, 2017, respectively. |

Revenue from Contract with Customer [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Revenue | 3. REVENUE Evergy's, Westar Energy's and KCP&L's revenues disaggregated by customer class are summarized in the following tables.
(a) KCP&L amounts are included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018. Retail Revenues The Evergy Companies' retail revenues are generated by the regulated sale of electricity to their residential, commercial and industrial customers within their franchised service territories. The Evergy Companies recognize revenue on the sale of electricity to their customers over time as the service is provided in the amount they have a right to invoice. Retail customers are billed on a monthly basis at the tariff rates approved by the KCC and MPSC based on customer kWh usage. Revenues recorded include electric services provided but not yet billed by the Evergy Companies. Unbilled revenues are recorded for kWh usage in the period following the customers' billing cycle to the end of the month. This estimate is based on net system kWh usage less actual billed kWhs. The Evergy Companies' estimated unbilled kWhs are allocated and priced by regulatory jurisdiction across the rate classes based on actual billing rates. The Evergy Companies also collect sales taxes and franchise fees from customers concurrent with revenue-producing activities that are levied by state and local governments. These items are excluded from revenue, and thus not reflected on the statements of income and comprehensive income, for Evergy, Westar Energy and KCP&L. Prior to the adoption of ASC 606, KCP&L recorded sales taxes and franchise fees collected from its Missouri customers gross on KCP&L's statements of comprehensive income within operating revenues and taxes other than income taxes. Wholesale Revenues The Evergy Companies' wholesale revenues are generated by the sale of wholesale power and capacity in circumstances when the power that the Evergy Companies generate is not required for customers in their service territory. These sales primarily occur within the SPP Integrated Marketplace. The Evergy Companies also purchase power from the SPP Integrated Marketplace and record sale and purchase activity on a net basis in wholesale revenue or fuel and purchased power expense. In addition, the Evergy Companies sell wholesale power and capacity through bilateral contracts to other counterparties, such as electric cooperatives, municipalities and other electric utilities. For both wholesale sales to the SPP Integrated Marketplace and through bilateral contracts, the Evergy Companies recognize revenue on the sale of wholesale electricity to their customers over time as the service is provided in the amount they have a right to invoice. With regards to the SPP Integrated Marketplace, wholesale sales are billed weekly based on the fixed transaction price determined by the market at the time of the sale and the MWh quantity purchased. With regards to bilateral contracts, wholesale sales are billed monthly based on the contractually determined transaction price and the kWh quantity purchased. Transmission Revenues The Evergy Companies' transmission revenues are generated by the use of their transmission networks by the SPP, which the Evergy Companies allow the SPP to access and operate on their behalf and the behalf of other SPP participants. As new transmission lines are constructed, they are included in the transmission network available to the SPP. In exchange for providing access, the SPP pays the Evergy Companies consideration determined by formula rates approved by FERC, which include the cost to construct and maintain the transmission lines and a return on investment. The price for access to the Evergy Companies' transmission networks are updated annually based on projected costs. Projections are updated to actual costs and the difference is included in subsequent year's prices. The Evergy Companies have different treatment for their legacy transmission facilities within the SPP, which results in different levels of transmission revenue being received from the SPP. Westar Energy's transmission revenues from SPP include amounts that Westar Energy pays to the SPP on behalf of its retail electric customers for the use of Westar Energy's legacy transmission facilities. These transmission revenues are mostly offset by SPP network transmission cost expense that Westar Energy pays on behalf of its retail customers. KCP&L and GMO do not pay the SPP for their retail customers’ use of the KCP&L and GMO legacy transmission facilities and correspondingly, their transmission revenues also do not reflect the associated transmission revenue from the SPP. The Evergy Companies recognize revenue on the sale of transmission service to their customers over time as the service is provided in the amount they have a right to invoice. Transmission service to the SPP is billed monthly based on a fixed transaction price determined by FERC formula transmission rates along with other SPP-specific charges and the MW quantity purchased. Industrial Steam and Other Revenues Evergy's industrial steam and other revenues are primarily generated by the regulated sale of industrial steam to GMO's steam customers. Evergy recognizes revenue on the sale of industrial steam to its customers over time as the service is provided in the amount that it has the right to invoice. Steam customers are billed on a monthly basis at the tariff rate approved by the MPSC based on customer MMBtu usage. Optional Exemption Evergy, Westar Energy and KCP&L do not disclose the value of unsatisfied performance obligations on certain bilateral wholesale contracts with an original expected duration of greater than one year for which they recognize revenue in the amount they have the right to invoice. |

Receivables | 4. RECEIVABLES The Evergy Companies' receivables are detailed in the following table.
(a) KCP&L amounts are not included in consolidated Evergy as of December 31, 2017. Evergy's, Westar Energy's and KCP&L's other receivables at September 30, 2018 and December 31, 2017 consisted primarily of receivables from partners in jointly-owned electric utility plants and wholesale sales receivables. As of September 30, 2018, other receivables for Evergy, Westar Energy and KCP&L included receivables from contracts with customers of $57.7 million, $52.8 million and $1.0 million, respectively. The Evergy Companies recorded bad debt expense related to contracts with customers as summarized in the following table.
(a) KCP&L amounts are included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018. Sale of Accounts Receivable – KCP&L and GMO KCP&L and GMO sell all of their retail electric accounts receivable to their wholly-owned subsidiaries, KCP&L Receivables Company and GMO Receivables Company, respectively, which in turn sell an undivided percentage ownership interest in the accounts receivable to Victory Receivables Corporation, an independent outside investor. Each of KCP&L Receivables Company's and GMO Receivables Company's sale of the undivided percentage ownership interest in accounts receivable to Victory Receivables Corporation is accounted for as a secured borrowing with accounts receivable pledged as collateral and a corresponding short-term collateralized note payable recognized on the balance sheets. At September 30, 2018, Evergy's accounts receivable pledged as collateral and the corresponding short-term collateralized note payable were $195.0 million. At September 30, 2018 and December 31, 2017, KCP&L's accounts receivable pledged as collateral and the corresponding short-term collateralized note payable were $130.0 million. KCP&L's receivable sale facility expires in September 2019 and allows for $130.0 million in aggregate outstanding principal amount of borrowings at any time. GMO's receivable sale facility expires in September 2019 and allows for $50.0 million in aggregate outstanding principal amount of borrowings from mid-November through mid-June and then $65.0 million from mid-June through mid-November. |

Regulated Operations [Abstract] | |
Rate Matters and Regulation | 5. RATE MATTERS AND REGULATION KCC Proceedings Westar Energy 2018 Transmission Delivery Charge In March 2018, the KCC issued an order adjusting Westar Energy's retail prices to include updated transmission costs as reflected in the FERC transmission formula rate (TFR). The new prices were effective in April 2018 and are expected to increase Westar Energy's annual retail revenues by $31.5 million. In August 2018, Westar Energy filed an updated Transmission Delivery Charge (TDC) tariff with the KCC to reflect the reduction in revenue requirement that occurred as a result of the Tax Cuts and Jobs Act. The updated filing requested new prices decreasing Westar Energy's annual retail revenues by approximately $20 million. In October 2018, the KCC issued an order approving the request with the new prices effective October 30, 2018. Westar Energy 2018 Rate Case Proceedings In February 2018, Westar Energy filed an application with the KCC to request a two-step change in rates, a decrease to retail revenues of approximately $2 million in September 2018 followed by an increase in retail revenues of approximately $54 million in February 2019, with a return on equity of 9.85% and a rate-making equity ratio of 51.6%. The request reflects costs associated with the completion of the Western Plains Wind Farm, the expiration of wholesale contracts currently reflected in retail prices as offsets to retail cost of service, the expiration of production tax credits from prior wind investments and an updated depreciation study, partially offset by the impact of the Tax Cuts and Jobs Act and a portion of the savings from the merger with Great Plains Energy. In June 2018, Westar Energy, the KCC staff and several other intervenors in the case reached a non-unanimous stipulation and agreement to settle all outstanding issues in the case. The stipulation and agreement provides for a decrease to retail revenues of $66.0 million, before rebasing property tax expense, with a return on equity of 9.3%, a rate-making equity ratio of 51.46% and does not include a second step revenue requirement change as included in Westar Energy's initial application. The stipulation and agreement also provides for an approximately $16 million increase associated with rebasing property tax expense, an approximately $46 million increase in depreciation expense, allows for the recovery of an approximately $41 million wholesale contract that expires in 2019 through Westar Energy's fuel recovery mechanism and reflects customer benefits related to the impacts of the Tax Cuts and Jobs Act, including a one-time bill credit of approximately $50 million to be provided to customers following the conclusion of the rate case. In September 2018, the KCC issued an order approving the non-unanimous stipulation and agreement. The rates established by the order took effect on September 27, 2018. KCP&L 2018 Rate Case Proceedings In May 2018, KCP&L filed an application with the KCC to request an increase to its retail revenues of $26.2 million before rebasing property tax expense, with a return on equity of 9.85% and a rate-making equity ratio of 49.8%. The request reflects the impact of the Tax Cuts and Jobs Act and increases in infrastructure investment costs. KCP&L also requested an additional $6.7 million increase associated with rebasing property tax expense. In October 2018, KCP&L, the KCC staff and other intervenors reached a unanimous settlement agreement to settle all outstanding issues in the case. The settlement agreement provides for a decrease to retail revenues of $10.7 million before rebasing property tax expense, with a return on equity of 9.3%, a rate-making equity ratio of 49.09% and a one-time bill credit of $36.9 million for customer benefits related to the impacts of the Tax Cuts and Jobs Act. The unanimous settlement agreement is subject to the approval of the KCC. The new rates are expected to go into effect in December 2018. MPSC Proceedings KCP&L 2018 Rate Case Proceedings In January 2018, KCP&L filed an application with the MPSC to request an increase to its retail revenues of $8.9 million before rebasing fuel and purchased power expense, with a return on equity of 9.85% and a rate-making equity ratio of 50.03%. The request reflects the impact of the Tax Cuts and Jobs Act and increases in infrastructure investment costs, transmission related costs and property tax costs. KCP&L also requested an additional $7.5 million increase associated with rebasing fuel and purchased power expense. In September 2018, KCP&L, MPSC staff and other intervenors in the case reached several non-unanimous stipulations and agreements to settle all outstanding issues in the case. The stipulations and agreements provide for a decrease to retail revenues of $21.1 million and a one-time customer benefit of $38.7 million related to the impact of the Tax Cuts and Jobs Act, which will be offset against existing KCP&L regulatory assets. The final amount of the one-time customer benefit related to the impact of the Tax Cuts and Jobs Act is dependent on the effective date of new rates. In October 2018, the MPSC issued an order approving the non-unanimous stipulations and agreements. The rates established by the order are expected to take effect no later than December 2018. GMO 2018 Rate Case Proceedings In January 2018, GMO filed an application with the MPSC to request a decrease to its retail revenues of $2.4 million before rebasing fuel and purchased power expense, with a return on equity of 9.85% and a rate-making equity ratio of 54.4%. The request reflects the impact of the Tax Cuts and Jobs Act and increases in infrastructure investment costs and transmission related costs. GMO also requested a $21.7 million increase associated with rebasing fuel and purchased power expense. In September 2018, GMO, MPSC staff and other intervenors in the case reached several non-unanimous stipulations and agreements to settle all outstanding issues in the case. The stipulations and agreements provide for a decrease to retail revenues of $24.0 million and a one-time bill credit of $29.3 million for customer benefits related to the impacts of the Tax Cuts and Jobs Act. The final amount of the one-time customer bill credit related to the impact of the Tax Cuts and Jobs Act is dependent on the effective date of new rates. In October 2018, the MPSC issued an order approving the non-unanimous stipulations and agreements. The rates established by the order are expected to take effect no later than December 2018. FERC Proceedings Westar Energy's TFR, effective in January 2018, includes projected 2018 transmission capital expenditures and operating costs and was expected to increase annual transmission revenues by $25.5 million. Due to the passage of the Tax Cuts and Jobs Act, Westar Energy requested permission from FERC to retroactively reflect the reduction in the federal corporate income tax rate in its 2018 prices. In April 2018, FERC granted the request and Westar Energy has recorded a regulatory liability as of September 30, 2018 of $5.9 million related to this request. It is estimated the revised TFR will increase 2018 revenues by $2.3 million when compared to 2017. Westar Energy's TFR, effective in January 2019, includes projected 2019 transmission capital expenditures and operating costs and is expected to decrease annual transmission revenues by $11.2 million when compared to 2018. |

Asset Retirement Obligations | 6. ASSET RETIREMENT OBLIGATIONS Asset Retirement Obligations (AROs) associated with tangible long-lived assets are legal obligations that exist under enacted laws, statutes and written or oral contracts, including obligations arising under the doctrine of promissory estoppel. These liabilities are recognized at estimated fair value as incurred with a corresponding amount capitalized as part of the cost of the related long-lived assets and depreciated over their useful lives. Accretion of the liabilities due to the passage of time is recorded to a regulatory asset and/or liability. Changes in the estimated fair values of the liabilities are recognized when known. Evergy, Westar Energy and KCP&L record the current portion of AROs within other current liabilities on their consolidated balance sheets. Westar Energy, KCP&L and GMO have AROs related to asbestos abatement and the closure and post-closure care of ponds and landfills containing coal combustion residuals (CCRs). In addition, Westar Energy and KCP&L have AROs related to decommissioning Wolf Creek Generating Station (Wolf Creek) and the retirement of wind generation facilities. Certain of the Evergy Companies' generating stations or other facilities may contain asbestos due to the age of the facilities, but no confirmation or measurement of the total amount of asbestos could be determined as of September 30, 2018. Due to the inability to reasonably estimate the quantities or the amount of disturbance that will be necessary during dismantlement at the end of the life of a plant or facility, the fair value of this ARO cannot be reasonably estimated at this time. Management will continue to monitor the obligation and will recognize a liability in the period in which sufficient information becomes available to reasonably estimate its fair value. The following table summarizes the change in the Evergy Companies' AROs for the periods ending September 30, 2018 and December 31, 2017.
(a) KCP&L amounts are only included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018. See Note 2 for more information regarding KCP&L's and GMO's ARO liabilities that Evergy assumed as a result of the merger. In June 2018, Evergy and Westar Energy recorded a $127.0 million revision in estimate primarily related to Westar Energy's ARO to decommission its 47% ownership share of Wolf Creek. |

Pension Plans and Other Employee Benefits | 7. PENSION PLANS AND OTHER EMPLOYEE BENEFITS Evergy and certain of its subsidiaries maintain, and Westar Energy and KCP&L participate in, qualified non-contributory defined benefit pension plans covering the majority of Westar Energy's and KCP&L's employees as well as certain non-qualified plans covering certain active and retired officers. Evergy is also responsible for its 94% share of Wolf Creek Nuclear Operating Corporation (WCNOC) defined benefit plans, consisting of Westar Energy's and KCP&L's respective 47% 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 Westar Energy'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. For the plans covering KCP&L'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 Westar Energy and KCP&L and their respective shares of WCNOC'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. 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.
(a) KCP&L amounts are included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018.
(a) KCP&L amounts are not included in consolidated Evergy for year to date September 30, 2017. The components of net periodic benefit costs other than the service cost component are included in other expense on the Evergy Companies' consolidated statements of income and comprehensive income. Year to date September 30, 2018, Evergy, Westar Energy and KCP&L made pension contributions of $53.1 million, $43.1 million and $23.7 million, respectively. Evergy's year to date September 30, 2018 pension contributions consist of Westar Energy's year to date September 30, 2018 contributions and KCP&L's contributions made following the closing of the merger in June 2018. Evergy expects to make additional pension contributions of $66.3 million in 2018 to satisfy the Employee Retirement Income Security Act of 1974, as amended (ERISA) funding requirements and KCC and MPSC rate orders, of which $4.9 million is expected to be paid by Westar Energy and $61.4 million is expected to be paid by KCP&L. Also in 2018, Evergy and KCP&L expect to make contributions of $4.6 million to the post-retirement benefit plans. |

Equity Compensation | 8. EQUITY COMPENSATION Upon the consummation of the merger, Evergy assumed both Westar Energy's Long-Term Incentive and Share Award plan (LTISA) and Great Plains Energy's Amended Long-Term Incentive Plan, which was renamed the Evergy, Inc. Long-Term Incentive Plan. All outstanding share-based payment awards under Westar Energy's LTISA vested at the closing of the merger transaction and were converted into a right to receive Evergy common stock with the exception of certain RSUs issued prior to the closing of the merger to certain officers and employees of Westar Energy. The vesting of these shares resulted in the recognition of $14.6 million of compensation expense in Evergy's and Westar Energy's consolidated statements of income for year to date September 30, 2018. All of Great Plains Energy's outstanding performance shares, restricted stock, RSUs and director deferred share units under Great Plains Energy's Amended Long-Term Incentive Plan were converted into equivalent Evergy performance shares, restricted stock, RSUs and director deferred share units at Great Plains Energy's merger exchange ratio of 0.5981. The estimated fair value of these converted awards that was allocated to the purchase price was $12.5 million, after-tax. See Note 2 for more information regarding the merger. The following table summarizes the Evergy Companies' equity compensation expense and the associated income tax (expense) benefit.
(a) KCP&L amounts are only included in consolidated Evergy from the date of the closing of the merger, June 4, 2018, through September 30, 2018. Performance Shares The vesting of performance shares is contingent upon achievement of specific performance goals over a stated period of time as approved by the Compensation and Leadership Development Committee of the Evergy Board. The number of performance shares ultimately vested can vary from the number of shares initially granted depending on either Great Plains Energy's performance prior to the closing of the merger transaction or Evergy's performance based on the stated performance period of the awards. Compensation expense for performance shares is calculated by recognizing the portion of the grant date fair value for each reporting period for which the requisite service has been rendered. Dividends are accrued over the vesting period and paid in cash based on the number of performance shares ultimately paid. The fair value of the converted Great Plains Energy performance share awards was estimated using the market value of Westar Energy's and Great Plains Energy's common stock at the valuation date and a Monte Carlo simulation technique that incorporates assumptions for inputs of expected volatilities, dividend yield and risk-free rates. Expected volatility is based on daily stock price change based on historical common stock information during a historical period commensurate with the remaining term of the performance period of the grant. The risk-free rate is based upon the rate at the time of the evaluation for zero-coupon government bonds with a maturity consistent with the remaining performance period of the grant. The dividend yield is based on the most recent dividends paid by Westar Energy, as Evergy's stock price assumes Westar Energy's stock price on a forward basis, and the grant date stock price on the valuation date. For the Great Plains Energy performance shares converted into Evergy awards upon the closing of the merger, inputs for expected volatility, dividend yield, and risk-free rates were 16.6% - 18.5% , 2.96% and 1.8% - 2.6%, respectively. Evergy and Westar Energy did not have any performance share awards issued and outstanding prior to the close of the merger. Performance share activity for year to date September 30, 2018 is summarized in the following table.
* weighted-average At September 30, 2018, the remaining weighted-average contractual term was 1.3 years. There were no shares granted for the three months ended September 30, 2018 and 2017, respectively. The weighted-average grant-date fair value of shares granted was $63.79 year to date September 30, 2018. At September 30, 2018, there was $10.6 million of total unrecognized compensation expense, net of forfeiture rates, related to converted Great Plains Energy performance shares granted under its Amended Long-Term Incentive Plan, which will be recognized over the remaining weighted-average contractual term. Restricted Stock Restricted stock cannot be sold or otherwise transferred by the recipient prior to vesting and has a value equal to the fair market value of the shares on the issue date. Restricted stock shares vest over a stated period of time with accruing reinvested dividends subject to the same restrictions. Compensation expense, calculated by multiplying shares by the grant-date fair value related to restricted stock, is recognized on a straight-line basis over the requisite service period of the award. Evergy and Westar Energy did not have any restricted stock awards issued and outstanding prior to the close of the merger. Restricted stock activity for year to date September 30, 2018 is summarized in the following table.
* weighted-average At September 30, 2018, the remaining weighted-average contractual term was 1.4 years. There were no shares granted for the three months ended September 30, 2018 and 2017, respectively. The weighted-average grant-date fair value of shares granted was $54.05 year to date September 30, 2018. At September 30, 2018, there was $3.1 million of total unrecognized compensation expense, net of forfeiture rates, related to converted Great Plains Energy restricted stock granted under its Amended Long-Term Incentive Plan, which will be recognized over the remaining weighted-average contractual term. The total fair value of shares vested was $0.2 million for the three months ended and year to date September 30, 2018. Restricted Share Units Evergy and Westar Energy have historically used RSUs for their stock-based compensation awards. RSU awards are grants that entitle the holder to receive shares of common stock as the awards vest. These RSU awards are defined as nonvested shares and do not include restrictions once the awards have vested. These RSUs have either taken the form of RSUs with only service requirements that vest solely upon the passage of time or RSUs with performance measures that vest upon expiration of the award term. All issued and outstanding Evergy and Westar Energy RSU awards with performance measures vested in connection with the closing of the merger transaction in June 2018. Evergy measures the fair value of RSUs with only service requirements based on the fair market value of the underlying common stock as of the grant date. RSU awards with only service conditions recognize compensation expense by multiplying shares by the grant-date fair value related to the RSU and recognizing it on a straight-line basis over the requisite service period for the entire award, including for those RSUs that have a graded vesting schedule. Nonforfeitable dividend equivalents, or the rights to receive cash equal to the value of dividends paid on Evergy's common stock, are paid on certain of these RSUs during the vesting period. Nonforfeitable dividends equivalents are recorded directly to retained earnings. RSU activity for awards with only service requirements for year to date September 30, 2018 is summarized in the following table.
* weighted-average At September 30, 2018, the remaining weighted-average contractual term related to RSU awards with only service requirements was 1.7 years. There were no RSUs granted for the three months ended September 30, 2018 and 2017, respectively. The weighted-average grant-date fair value of RSUs granted with only service requirements was $52.16 and $53.25 year to date September 30, 2018, and 2017, respectively. At September 30, 2018, there was $9.5 million of unrecognized compensation expense related to unvested RSUs. There were no RSUs with only service requirements that vested for the three months ended September 30, 2018. The total fair value of RSUs with only service requirements that vested year to date September 30, 2018 was $16.0 million. The total fair value of RSUs with only service requirements that vested for the three months ended and year to date September 30, 2017 was $0.2 million and $3.8 million, respectively. |

Short-term Borrowings and Short-term Bank Lines of Credit | 9. SHORT-TERM BORROWINGS AND SHORT-TERM BANK LINES OF CREDIT In September 2018, Evergy entered into a $2.5 billion master credit facility which expires in 2023. Evergy, Westar Energy, KCP&L and GMO 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. A default by any borrower under the facility or one of their significant subsidiaries on other indebtedness totaling more than $100.0 million constitutes a default under the facility. Under the terms of this facility, each of Evergy, Westar Energy, KCP&L and GMO 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, 2018, Evergy, Westar Energy, KCP&L and GMO were in compliance with this covenant. In connection with the entry into the master credit facility, each of Evergy (as successor to Great Plains Energy), Westar Energy, KCP&L and GMO terminated its existing credit facilities in September 2018. The following table summarizes the committed credit facilities (excluding receivable sale facilities) available to the Evergy Companies as of September 30, 2018 and December 31, 2017.
(a) KCP&L amounts are not included in consolidated Evergy as of December 31, 2017. (b) $20.7 million of Westar Energy's $730.0 million and $270.0 million revolving credit facilities expired in September 2017. |

Debt Disclosure [Abstract] | |||||||||
Long-Term Debt | 10. LONG-TERM DEBT As of September 30, 2018, Evergy's outstanding long-term debt, including current maturities, includes $3,659.7 million related to KCP&L, GMO and the assumed long-term debt of Great Plains Energy discussed further below. This amount also includes $153.0 million of fair value adjustments recorded in connection with purchase accounting for the merger transaction, which are not part of future principal payments and will amortize over the remaining life of the associated debt instruments. See Note 2 for more information regarding the merger transaction. The series of long-term debt obligations originally issued by Great Plains Energy and assumed by Evergy, Inc. as part of the merger transaction were:
KCP&L Senior Notes In March 2018, KCP&L issued, at a discount, $300.0 million of 4.20% unsecured Senior Notes, maturing in 2048. KCP&L also repaid its $350.0 million of 6.375% unsecured Senior Notes at maturity in March 2018. KCP&L EIRR Bond Remarketing In July 2018, KCP&L remarketed its unsecured Series 2008 Environmental Improvement Revenue Refunding (EIRR) bonds maturing in 2038 totaling $23.4 million at a fixed rate of 2.75% through June 30, 2022. GMO Senior Notes As a result of the consummation of the merger transaction, a change in control provision in GMO's Series A, B and C Senior Notes was triggered that allowed holders a one-time option to elect for early repayment of their notes at par value, plus accrued interest. Several holders of GMO's Series A and B Senior Notes elected this option and in July 2018, GMO redeemed $89.0 million of its Series A Senior Notes and $15.0 million of its Series B Senior Notes. |

Fair Value Measurements | 11. 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 include 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. 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.
(a) Includes current maturities. (b) Book value as of September 30, 2018 includes $153.0 million of fair value adjustments recorded in connection with purchase accounting for the Great Plains Energy and Westar Energy merger, which are not part of future principal payments and will amortize over the remaining life of the associated debt instrument. See Note 2 for more information regarding the merger transaction. (c) KCP&L amounts are not included in consolidated Evergy as of December 31, 2017. Recurring Fair Value Measurements The following tables include the Evergy Companies' balances of financial assets and liabilities measured at fair value on a recurring basis.
Certain Evergy and Westar Energy 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 Westar Energy investments.
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 Westar Energy. 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 Westar Energy's rabbi trust in the consolidated statements of income. The following table summarizes the net unrealized gains (losses) for the Evergy Companies' nuclear decommissioning trusts and rabbi trusts.
(a) KCP&L amounts are only included in consolidated Evergy from the date of the merger, June 4, 2018 through September 30, 2018. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 12. COMMITMENTS AND CONTINGENCIES Contractual Commitments For information regarding long-term contractual commitments, including fuel and purchased power commitments, see Note 14 of the Westar Energy 2017 Form 10-K and Note 15 of the Great Plains Energy and KCP&L combined 2017 Form 10-K. Environmental Matters Set forth below are descriptions of contingencies related to environmental matters that may impact the Evergy Companies 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. 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. Cross-State Air Pollution Update Rule In September 2016, the Environmental Protection Agency (EPA) finalized the Cross-State Air Pollution Update Rule. The final rule addresses interstate transport of nitrogen oxides emissions in 22 states including Kansas, Missouri and Oklahoma during the ozone season and the impact from the formation of ozone on downwind states with respect to the 2008 ozone National Ambient Air Quality Standards (NAAQS). Starting with the 2017 ozone season, the final rule revised the existing ozone season allowance budgets for Missouri and Oklahoma and established an ozone season budget for Kansas. In June 2018, the EPA proposed that the Cross-State Air Pollution Update Rule satisfied the "Good Neighbor" obligations for the 2008 ozone NAAQS and therefore the EPA is proposing no additional reduction in the current ozone season allowance budgets. Various states and others are challenging the Cross-State Air Pollution Update Rule in the U.S. Court of Appeals for the D.C. Circuit (D.C. Circuit) but the rule remains in effect. It is not expected that this rule will have a material impact on the Evergy Companies' operations and consolidated financial results. National Ambient Air Quality Standards Under the Clean Air Act Amendments of 1990 (Clean Air Act), the EPA sets NAAQS for certain emissions known as the “criteria pollutants” considered harmful to public health and the environment, including two classes of particulate matter (PM), ozone, nitrogen dioxide (NO2) (a precursor to ozone), carbon monoxide and sulfur dioxide (SO2), which result from fossil fuel combustion. Areas meeting the NAAQS are designated attainment areas while those that do not meet the NAAQS are considered nonattainment areas. Each state must develop a plan to bring nonattainment areas into compliance with the NAAQS. NAAQS must be reviewed by the EPA at five-year intervals. In October 2015, the EPA strengthened the ozone NAAQS by lowering the standards from 75 ppb to 70 ppb. In September 2016, the Kansas Department of Health & Environment (KDHE) recommended to the EPA that they designate eight counties in the state of Kansas as in attainment with the standard, and each remaining county in Kansas as attainment/unclassifiable. Also, in September 2016, the Missouri Department of Natural Resources (MDNR) recommended to the EPA that they designate all Missouri counties in KCP&L's and GMO's service territories as attainment/unclassifiable. In November 2017, the EPA designated all counties in the State of Kansas as well as the Missouri counties in KCP&L's and GMO's service territories as attainment/unclassifiable. It is not expected that this will have a material impact on the Evergy Companies' consolidated financial results. In December 2012, the EPA strengthened an existing NAAQS for one class of PM. In December 2014, the EPA designated the entire state of Kansas and those portions of Missouri served by KCP&L and GMO as attainment/unclassifiable with the standard. It is not expected that this will have a material impact on the Evergy Companies' operations or consolidated financial results. The Evergy Companies continue to communicate with their regulatory agencies regarding these standards and evaluate what impact the revised NAAQS could have on their operations and consolidated financial results. If areas surrounding the Evergy Companies' facilities are designated in the future as nonattainment and/or it is required to install additional equipment to control emissions at facilities of the Evergy Companies, it could have a material impact on the operations and consolidated financial results of 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 federal Clean Air Act 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 October 2015, the EPA published a rule establishing new source performance standards (NSPS) for GHGs that limit CO2 emissions for new, modified and reconstructed coal and natural gas fueled electric generating units to various levels per MWh depending on various characteristics of the units. Legal challenges to the GHG NSPS have been filed in the D.C. Circuit by various states and industry members. Also in October 2015, the EPA published a rule establishing guidelines for states to regulate CO2 emissions from existing power plants. The standards for existing plants are known as the Clean Power Plan (CPP). Under the CPP, interim emissions performance rates must be achieved beginning in 2022 and final emissions performance rates must be achieved by 2030. Legal challenges to the CPP were filed by groups of states and industry members, including Westar Energy, in the D.C. Circuit. The CPP was stayed by the Supreme Court in February 2016 and, accordingly, is not currently being implemented by the states. In April 2017, the EPA published in the Federal Register a notice of withdrawal of the proposed CPP federal plan, proposed model trading rules and proposed Clean Energy Incentive Program design details. Also in April 2017, the EPA published a notice in the Federal Register that it was initiating administrative reviews of the CPP and the GHG NSPS. In October 2017, the EPA issued a proposed rule to repeal the CPP. The proposed rule indicates the CPP exceeds EPA’s authority and the EPA has not determined whether they will issue a replacement rule. The EPA solicited comments on the legal interpretations contained in this rulemaking. In December 2017, the EPA issued an advance notice of proposed rulemaking to solicit feedback on specific areas of the CPP that could be changed. In August 2018, the EPA published in the Federal Register proposed regulations which contained (1) emission guidelines for GHG emissions from existing electric utility generating units (EGUs), (2) revisions to emission guideline implementing regulations and (3) revisions to the new source review (NSR) program. The proposed emission guidelines are better known as the Affordable Clean Energy (ACE) Rule. The ACE Rule would establish emission guidelines for states to use in the development of plans to reduce GHG emissions from existing coal-fired EGUs. The ACE Rule is also the replacement rule for the CPP. The ACE rule proposes to determine the “best system of emission reduction” for GHG emissions from existing coal-fired EGUs as on-site, heat-rate efficiency improvements. The proposed rule also provides states with a list of candidate technologies that can be used to establish standards of performance and incorporate these performance standards into state plans. In order for the states to be able to effectively implement the proposed emission guidelines contained in the ACE Rule, the EPA is proposing new regulations under 111(d) of the Clean Air Act to help clarify this process. In addition, the EPA is proposing revisions to the NSR program that will reduce the likelihood of triggering NSR for proposed heat-rate efficiency improvement projects at existing coal-fired EGUs. The EPA accepted comments on these three proposed regulatory changes until October 31, 2018. Due to the future uncertainty of the CPP and ACE rules, the Evergy Companies cannot determine the impact on their operations or consolidated financial results, but the cost to comply with the CPP, should it be upheld and implemented in its current or a substantially similar form, or ACE in its current or a substantially similar form, could be material. Water The Evergy Companies discharge some of the water used in generation and other operations. This water may contain substances deemed to be pollutants. Revised rules governing such discharges from coal-fired power plants were issued in November 2015. The final rule 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 these requirements vary from 2018 to 2023. In April 2017, the EPA announced it is reconsidering the ELG rule and court challenges have been placed in abeyance pending the EPA's review. In September 2017, the EPA finalized a rule to postpone the compliance dates for the new, more stringent, effluent limitations and pretreatment standards for bottom ash transport water and flue gas desulfurization wastewater. These compliance dates have been postponed for two years while the EPA completes its administrative reconsideration of the ELG rule. The Evergy Companies are evaluating the final rule and related developments and cannot predict the resulting impact on their operations or consolidated financial results, but believe costs to comply could be material if the rule is implemented in its current or substantially similar form. In October 2014, the EPA's final standards for cooling intake structures at power plants to protect aquatic life took effect. The standards, based on Section 316(b) of the federal Clean Water Act (CWA), require subject facilities to choose among seven best available technology options to reduce fish impingement. In addition, some facilities must conduct studies to assist permitting authorities to determine whether and what site-specific controls, if any, would be required to reduce entrainment of aquatic organisms. The Evergy Companies' current analysis indicates this rule will not have a significant impact on their coal plants that employ cooling towers or cooling lakes that can be classified as closed cycle cooling and do not expect the impact from this rule to be material. Plants without closed cycle cooling are under evaluation for compliance with these standards and may require additional controls that could be material. KCP&L holds a permit from MDNR covering water discharge from its Hawthorn Station. The permit authorizes KCP&L to, among other things, withdraw water from the Missouri River for cooling purposes and return the heated water to the Missouri River. KCP&L has applied for a renewal of this permit and the EPA has submitted an interim objection letter regarding the allowable amount of heat that can be contained in the returned water. Until this matter is resolved, KCP&L continues to operate under its current permit. Evergy and KCP&L cannot predict the outcome of this matter; however, while less significant outcomes are possible, this matter may require a reduction in generation, installation of cooling towers or other technology to cool the water, or both, any of which could have a material impact on Evergy's and KCP&L's operations and consolidated financial results. In June 2015, the EPA along with the U.S. Army Corps of Engineers issued a final rule, effective August 2015, defining the Waters of the United States (WOTUS) for purposes of the CWA. This rulemaking has the potential to impact all programs under the CWA. Expansion of regulated waterways is possible under the rule depending on regulating authority interpretation, which could impact several permitting programs. Various states and others have filed lawsuits challenging the WOTUS rule. In February 2018, the EPA and the U.S. Army Corps of Engineers finalized a rule adding an applicability date to the 2015 rule, which makes the implementation date of the rule February 2020. In July 2017, the EPA and the U.S. Army Corps of Engineers published in the Federal Register a proposed rule that would, if implemented, reinstate the definition of WOTUS that existed prior to the June 2015 expansion of the definition. Final action on the proposed rule is expected in 2018 as it is currently at the Office of Management and Budget for inter-agency review. The Evergy Companies are currently evaluating the WOTUS rule and related developments but do not believe the rule, if upheld and implemented in its current or substantially similar form, will have a material impact on the Evergy Companies' operations or consolidated financial results. Regulation of Coal Combustion Residuals In the course of operating their coal generation plants, the Evergy Companies produce CCRs, including fly ash, gypsum and bottom ash. Some of this ash production is recycled, principally by selling to the aggregate industry. The EPA published a rule to regulate CCRs in April 2015, which will require additional CCR handling, processing and storage equipment and closure of certain ash disposal units. The Water Infrastructure Improvements for the Nation (WIIN) Act allows states to achieve delegated authority for CCR rules from the EPA. This has the potential to impact compliance options. In July 2018, the KDHE submitted a CCR permit program application to the EPA under authority of the WIIN Act. Final action on the application by the EPA is expected to occur within one year from the application date. MDNR is working on a rule revision which will allow the state to apply for authority over the federal CCR regulation. The application is expected to be submitted to the EPA in early 2019. Similar to the process in Kansas, this would allow Missouri state regulators to gain control of the CCR program. It will take up to one year from submittal of the Missouri application for EPA to take final action and grant authority to the state. On July 30, 2018, the EPA published in the Federal Register a final rule called the Phase I CCR Remand Rule in order to modify portions of the 2015 rulemaking. The Phase I rule provides a timeline extension for unlined impoundments and landfills that must close due to groundwater impacts or location restrictions. The rule also sets risk-based limits for certain groundwater constituents where a maximum contaminant level did not previously exist. These rule modifications add flexibility when assessing compliance. On August 21, 2018, the D.C. Circuit court issued a ruling in the CCR rule litigation between the Utility Solid Waste Activities Group, the EPA and environmental organizations. Portions of the rule were vacated and were remanded back to EPA for potential modification. Potential revisions to remanded sections could force all unlined surface impoundments to close regardless of groundwater conditions. Any changes to the rule based on this court decision will require additional rulemaking from the EPA. The Evergy Companies have recorded AROs for their current estimates for the closure of ash disposal ponds but the revision of these AROs may be required in the future due to changes in existing CCR regulations, changes in interpretation of existing CCR regulations, the results of groundwater monitoring of CCR units, or changes in the timing or cost to close ash disposal ponds. If revisions to these AROs are necessary, the impact on the Evergy Companies' operations or consolidated financial results could be material. Storage of Spent Nuclear Fuel Under the Nuclear Waste Policy Act of 1982, the Department of Energy (DOE) is responsible for the permanent disposal of spent nuclear fuel. In 2010, the DOE filed a motion with the Nuclear Regulatory Commission (NRC) to withdraw its then pending application to construct a national repository for the disposal of spent nuclear fuel and high-level radioactive waste at Yucca Mountain, Nevada. An NRC board denied the DOE's motion to withdraw its application and the DOE appealed that decision to the full NRC. In 2011, the NRC issued an evenly split decision on the appeal and also ordered the licensing board to close out its work on the DOE's application by the end of 2011 due to a lack of funding. These agency actions prompted the states of Washington and South Carolina, and a county in South Carolina, to file a lawsuit in a federal Court of Appeals asking the court to compel the NRC to resume its license review and to issue a decision on the license application. In August 2013, the court ordered the NRC to resume its review of the DOE's application. The NRC has not yet issued its decision. Wolf Creek has elected to build a dry cask storage facility to expand its existing on-site spent nuclear fuel storage, which is expected to provide additional capacity prior to 2025. Wolf Creek has finalized a settlement agreement through 2019 with the DOE for reimbursement of costs to construct this facility that would not have otherwise been incurred had the DOE begun accepting spent nuclear fuel. The Evergy Companies expect the majority of the remaining cost to construct the dry cask storage facility that would not have otherwise been incurred will be reimbursed by the DOE. The Evergy Companies cannot predict when, or if, an off-site storage site or alternative disposal site will be available to receive Wolf Creek's spent nuclear fuel and will continue to monitor this activity. |

KCP&L and Westar Energy employees also provide one another with shared service support, including costs related to human resources, information technology, accounting and legal services. The operating expenses and capital costs billed from KCP&L to Westar Energy were $35.5 million and $50.8 million, respectively, for the three months ended and year to date September 30, 2018. The operating and capital costs billed from Westar Energy to KCP&L were $4.8 million and $10.8 million, respectively, for the three months ended and year to date September 30, 2018.

Stockholders' Equity Note [Abstract] | |
Shareholders' Equity | 15. SHAREHOLDERS' EQUITY Evergy's authorized capital stock consists of 600 million shares of common stock, without par value, and 12 million shares of Preference Stock, without par value. Evergy Registration Statements In November 2018, Evergy filed an automatic shelf registration statement providing for the sale of unlimited amounts of securities with the SEC, which expires in November 2021. In September 2018, Evergy registered shares of its common stock with the SEC for its Dividend Reinvestment and Direct Stock Purchase Plan. Shares issued under the plan may be either newly issued shares or shares purchased on the open market. In June 2018, Evergy registered shares of its common stock with the SEC for the Great Plains Energy 401(k) Savings Plan and Westar Energy, Inc. Employees' 401(k) Savings Plan, among other compensation plans, that Evergy assumed in connection with the merger transaction. Shares issued under the plans may be either newly issued shares or shares purchased on the open market. Common Stock Repurchase Plan In July 2018, the Evergy Board authorized the repurchase of up to 60 million shares of Evergy's common stock. Although this repurchase authorization has no expiration date, Evergy expects to repurchase the 60 million shares by mid-2020. Evergy plans to utilize various methods to effectuate the share repurchase program, including but not limited to, a series of transactions that may include accelerated share repurchases, open market transactions or other means, subject to market conditions and applicable legal requirements. The repurchase program may be suspended, discontinued or resumed at any time. Year to date September 30, 2018, Evergy had total repurchases of common stock of approximately $486 million and had repurchased 6.9 million shares under the repurchase program, which included shares repurchased under accelerated share repurchase (ASR) agreements which had not reached final settlement as of September 30, 2018, and are discussed further below. Evergy retires repurchased common stock shares in the period the shares are repurchased. In August 2018, Evergy entered into two ASR agreements with financial institutions to purchase $450.0 million of Evergy common stock. In August 2018, the financial institutions delivered to Evergy 6.3 million shares of common stock, representing a partial settlement of the contracts, based on then-current market prices and Evergy paid a total of $450.0 million. The upfront payment was recorded as a reduction to Evergy, Inc. shareholders' equity on Evergy's consolidated balance sheets and as a repurchase of common stock on Evergy's consolidated statements of cash flows. The final number of shares of Evergy common stock that Evergy may receive or be required to remit upon final settlement of the ASR agreements will be based on the average daily volume weighted-average price of Evergy common stock during the term of the ASR agreements, less a negotiated discount. Final settlement of each ASR agreement will occur by the end of November 2018 but may occur earlier at the option of the financial institutions. In October 2018, one of the ASR agreements was settled early at the option of the financial institution, which resulted in the delivery to Evergy of 848,226 additional shares of Evergy common stock at no additional cost. Evergy expects that the final settlement of the remaining ASR agreement will also result in the delivery of additional shares of common stock to Evergy at no additional cost. Evergy reflects the ASRs as a repurchase of common stock in the period the shares are delivered for purposes of calculating earnings per share and as forward contracts indexed to its own common stock. The ASRs meet all of the applicable criteria for equity classification and therefore are not accounted for as derivative instruments. Dividend Restrictions Evergy depends on its subsidiaries to pay dividends on its common stock. The Evergy Companies have certain restrictions stemming from statutory requirements, corporate organizational documents, covenants and other conditions that could affect dividend levels or the ability to pay dividends. The KCC order authorizing the merger transaction requires Evergy to maintain consolidated common equity of at least 35% of total consolidated capitalization. Further, Evergy's master credit facility requires it to maintain a consolidated indebtedness to consolidated capitalization ratio of not more than 0.65 to 1.00 at all times. Under the Federal Power Act, Westar Energy, KCP&L and GMO generally can pay dividends only out of retained earnings. Certain conditions in the MPSC and KCC orders authorizing the merger transaction also require Westar Energy and KCP&L to maintain consolidated common equity of at least 40% of total capitalization. Other conditions in the MPSC and KCC merger orders require Westar Energy, KCP&L and GMO to maintain credit ratings of at least investment grade. If Westar Energy's, KCP&L's or GMO's credit ratings are downgraded below the investment grade level as a result of their affiliation with Evergy or any of Evergy's affiliates, the impacted utility shall not pay a common dividend without KCC or MPSC approval or until the impacted utility's investment grade credit rating has been restored. The master credit facility of Evergy, Westar Energy, KCP&L and GMO and the note purchase agreement for GMO's Series A, B and C Senior Notes contain covenants requiring the respective company to maintain a consolidated indebtedness to consolidated total capitalization ratio of not more than 0.65 to 1.00 at all times. As of September 30, 2018, all of Evergy's and Westar Energy's retained earnings and net income were free of restrictions and KCP&L had a retained earnings restriction of $227.4 million. Evergy's subsidiaries had restricted net assets of approximately $5.2 billion as of September 30, 2018. These restrictions are not expected to affect the Evergy Companies' ability to pay dividends at the current level for the foreseeable future. |

Variable Interest Entities | 16. VARIABLE INTEREST ENTITIES In determining the primary beneficiary of a VIE, the Evergy Companies assess the entity's purpose and design, including the nature of the entity's activities and the risks that the entity was designed to create and pass through to its variable interest holders. A reporting enterprise is deemed to be the primary beneficiary of a VIE if it has (a) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (b) the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The primary beneficiary of a VIE is required to consolidate the VIE. The trust holding an 8% interest in Jeffrey Energy Center was a VIE until the expiration of a purchase option in July 2017. The trust holding KGE's 50% interest in La Cygne Unit 2 is a VIE and KGE remains the primary beneficiary of the trust. All involvement with entities by the Evergy Companies is assessed to determine whether such entities are VIEs and, if so, whether or not the Evergy Companies are the primary beneficiaries of the entities. The Evergy Companies also continuously assess whether they are the primary beneficiary of the VIE with which they are involved. Prospective changes in facts and circumstances may cause identification of the primary beneficiary to be reconsidered. 8% Interest in Jeffrey Energy Center Under an agreement that expires in January 2019, Westar Energy leases an 8% interest in Jeffrey Energy Center from a trust. The trust was financed with an equity contribution from an owner participant and debt issued by the trust. The trust was created specifically to purchase the 8% interest in Jeffrey Energy Center and lease it to a third party, and does not hold any other assets. Westar Energy met the requirements to be considered the primary beneficiary of the trust until July 2017, when a contractual option to purchase the 8% interest in the plant covered by the lease expired. Accordingly, Westar Energy deconsolidated the trust in the third quarter of 2017. 50% Interest in La Cygne Unit 2 Under an agreement that expires in September 2029, KGE entered into a sale-leaseback transaction with a trust under which the trust purchased KGE's 50% interest in La Cygne Unit 2 and subsequently leased it back to KGE. The trust was financed with an equity contribution from an owner participant and debt issued by the trust. The trust was created specifically to purchase the 50% interest in La Cygne Unit 2 and lease it back to KGE, and does not hold any other assets. KGE meets the requirements to be considered the primary beneficiary of the trust. In determining the primary beneficiary of the trust, KGE concluded that the activities of the trust that most significantly impact its economic performance and that KGE has the power to direct include (1) the operation and maintenance of the 50% interest in La Cygne Unit 2 and (2) KGE's ability to exercise a purchase option at the end of the agreement at the lesser of fair value or a fixed amount. KGE has the potential to receive benefits from the trust that could potentially be significant if the fair value of the 50% interest in La Cygne Unit 2 at the end of the agreement is greater than the fixed amount. The following table summarizes the assets and liabilities related to the VIE described above that are recorded on Evergy's and Westar Energy's consolidated balance sheets.
All of the liabilities noted in the table above relate to the purchase of the property, plant and equipment of the VIE. The assets of the VIE can be used only to settle obligations of the VIE and the VIE's debt holders have no recourse to the general credit of Evergy and Westar Energy. Evergy and Westar Energy have not provided financial or other support to the VIE and are not required to provide such support. Evergy and Westar Energy did not record any gain or loss upon the initial consolidation of the VIE. |

Income Tax Disclosure [Text Block] | 17. TAXES Components of income tax expense are detailed in the following tables.
Effective Income Tax Rates Effective income tax rates reflected in the financial statements and the reasons for their differences from the statutory federal rates are detailed in the following tables.
The decrease in Evergy's state tax rate change for year to date September 30, 2018, compared to the same period in 2017, is primarily due to the revaluation of Westar Energy's state deferred income tax assets and liabilities based on the Evergy composite tax rate as a result of the merger.
The decrease in Westar Energy's state tax rate change for year to date September 30, 2018, compared to the same period in 2017, is primarily due to the revaluation of Westar Energy's state deferred income tax assets and liabilities based on the Evergy composite tax rate as a result of the merger.
The increase in KCP&L's state tax rate change for year to date September 30, 2018, compared to the same period in 2017, is primarily due to the revaluation of KCP&L's state deferred income tax assets and liabilities based on the Evergy composite tax rate as a result of the merger, partially offset by a revaluation of KCP&L's state deferred income tax assets and liabilities as a result of the enactment of Missouri state income tax reform in June 2018. Federal Tax Reform In December 2017, the U.S. Congress passed and President Donald Trump signed Public Law No. 115-97, commonly referred to as the Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act represents the first major reform in U.S. income tax law since 1986. Most notably, the Tax Cuts and Jobs Act reduces the current top corporate income tax rate from 35% to 21% beginning in 2018, repeals the corporate Alternative Minimum Tax (AMT), makes existing AMT tax credit carryforwards refundable, and changes the deductibility and taxability of certain items, among other things. Prior to the change in tax rates that has been reflected in their 2018 rate cases,Westar Energy, KCP&L and GMO recovered the cost of income taxes in rates from their customers based on the 35% federal corporate income tax rate. In January 2018, the KCC issued an order requiring certain regulated public utilities, including Westar Energy and KCP&L, to begin recording a regulatory liability for the difference between the new corporate tax rate and amounts currently collected in rates. In May 2018 and June 2018, Westar Energy and KCP&L entered into settlement agreements with KCC staff and other intervenors in which they further agreed to begin deferring any impacts of the Tax Cuts and Jobs Act on their excess accumulated deferred income taxes to a regulatory liability. The KCC approved these settlement agreements in June 2018. KCP&L and GMO had also recorded regulatory liabilities in 2018 due to the probability that they would also be required to make similar refunds to their Missouri customers. The final regulatory treatment of these regulatory liabilities was determined in each of Westar Energy's, KCP&L's and GMO's rate cases with the KCC and MPSC. See Note 5 for more information. As of September 30, 2018, Evergy, Westar Energy and KCP&L had recorded regulatory liabilities for refunds to customers related to the impacts of the Tax Cuts and Jobs Act of $155.1 million, $66.3 million and $64.6 million, respectively. Missouri Tax Reform On June 1, 2018, the Missouri governor signed Senate Bill (S.B.) 884 into law. Most notably, S.B. 884 reduces the corporate income tax rate from 6.25% to 4.0% beginning in 2020, provides for the mandatory use of the single sales factor formula and eliminates intercompany transactions between corporations that file a consolidated Missouri income tax return. As a result of the change in the Missouri corporate income tax rate, KCP&L revalued and restated its deferred income tax assets and liabilities as of June 1, 2018. KCP&L decreased its net deferred income tax liabilities by $46.6 million, primarily consisting of a $28.8 million adjustment for the revaluation and restatement of deferred income tax assets and liabilities included in Missouri jurisdictional rate base and a $9.9 million tax gross-up adjustment for ratemaking purposes. The decrease to KCP&L's net deferred income tax liabilities included in Missouri jurisdictional rate base were offset by a corresponding increase in regulatory liabilities. The net regulatory liabilities will be amortized to customers over a period to be determined in a future rate case. KCP&L recognized $15.5 million of income tax benefit primarily related to the difference between KCP&L's revaluation of its deferred income tax assets and liabilities for financial reporting purposes and the amount of the revaluation pertaining to KCP&L's Missouri jurisdictional rate base. |

Principles of Consolidation | Principles of Consolidation Westar Energy was determined to be the accounting acquirer in the merger and thus, the predecessor of Evergy. Therefore, Evergy's consolidated financial statements reflect the results of operations of Westar Energy for the three months ended and year to date September 30, 2017 and the financial position of Westar Energy as of December 31, 2017. Evergy had separate operations for the period beginning with the quarter ended June 30, 2018, and references to amounts for periods after the closing of the merger relate to Evergy. The results of Great Plains Energy's direct subsidiaries have been included in Evergy's results of operations from the date of the closing of the merger and thereafter. KCP&L and Westar Energy will continue to maintain their current reporting requirements as Securities and Exchange Commission (SEC) registrants. KCP&L has elected not to apply "push-down accounting" related to the merger, whereby the adjustments of assets and liabilities to fair value and the resulting goodwill would be recorded on the financial statements of the acquired subsidiary. These adjustments for KCP&L, as well as those related to the acquired assets and liabilities of Great Plains Energy and its other direct subsidiaries, are reflected at consolidated Evergy. Each of Evergy's, Westar Energy's and KCP&L's 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). In preparing financial statements that conform to generally accepted accounting principles (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. These unaudited consolidated financial statements have been prepared in accordance with GAAP for the United States of America 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. Because the unaudited consolidated financial statements and notes do not include all of the information and notes required by GAAP for annual financial statements, the unaudited consolidated financial statements and other information included in this quarterly report should be read in conjunction with the Westar Energy First Quarter 2018 Quarterly Report on Form 10-Q, the Great Plains Energy and KCP&L combined First Quarter 2018 Quarterly Report on Form 10-Q, the Westar Energy 2017 Form 10-K and the Great Plains Energy and KCP&L combined 2017 Form 10-K. Certain changes in classification and corresponding reclassification of prior period data were made in Evergy's, Westar Energy's and KCP&L's unaudited consolidated balance sheets, statements of income and comprehensive income and unaudited statements of cash flows for comparative purposes. Evergy reflects the classifications of Westar Energy as the accounting acquirer in the merger. These reclassifications did not affect Evergy's, Westar Energy's or KCP&L's net income or Evergy's, Westar Energy's or KCP&L's cash flows from operations, investing or financing. Most significantly for Westar Energy's consolidated balance sheets as of December 31, 2017 was the reclassification of $50.2 million from accrued employee benefits (currently reported as pension and post-retirement liability) to other long-term liabilities. Most significantly for KCP&L's consolidated balance sheets, current regulatory assets and liabilities have been presented separately from the non-current portions in each respective consolidated balance sheet where recovery or refund is expected within the next 12 months. |

Earnings Per Share | Earnings Per Share Evergy has participating securities in the form of unvested restricted share units (RSUs) with nonforfeitable rights to dividend equivalents that receive dividends on an equal basis with dividends declared on common stock. As a result, Evergy applies the two-class method of computing basic and diluted earnings per share (EPS). To compute basic EPS, Evergy divides the earnings allocated to common stock by the weighted average number of common shares outstanding. Diluted EPS includes the effect of issuable common shares resulting from RSUs with forfeitable rights to dividend equivalents, performance shares and restricted stock. Evergy computes the dilutive effects of potential issuances of common shares using the treasury stock method. |

New Accounting Standards | New Accounting Standards Intangibles - Internal-Use Software In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for recording implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. An entity in a hosting arrangement that is a service contract will need to determine which project stage (that is, preliminary project stage, application development stage or post-implementation stage) an implementation activity relates. Costs for implementation activities in the application development stage are recorded as a prepaid asset depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are incurred. Costs that are recorded to a prepaid asset are to be expensed over the term of the hosting arrangement. The new guidance is effective for annual periods beginning after December 15, 2019 and interim periods within those fiscal years. The new guidance can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted. The Evergy Companies are currently evaluating the new guidance including the timing of adoption. Compensation - Retirement Benefits In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits, which requires an employer to disaggregate the service cost component from the other components of net benefit cost. The service cost component is to be reported in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The non-service cost components are to be reported separately from service costs and outside of a subtotal of income from operations. The amendments in this update allow only the service cost component to be eligible for capitalization as part of utility plant. The non-service cost components that are no longer eligible for capitalization as part of utility plant will be recorded as a regulatory asset. The new guidance is to be applied retrospectively for the presentation of service cost and non-service cost components in the income statement and prospectively for the capitalization of the service cost component and is effective for interim and annual periods beginning after December 15, 2017. The Evergy Companies adopted ASU No. 2017-07 on January 1, 2018, and accordingly have retrospectively adjusted prior periods. The Evergy Companies utilized the practical expedient that allows for the use of amounts disclosed in Note 7 for applying the retrospective presentation to the 2017 consolidated statements of income and comprehensive income. The following table reflects the retrospective adjustments in the line items of the Evergy Companies' consolidated statements of income and comprehensive income associated with the adoption of ASU No. 2017-07.
(a) KCP&L amounts are not included in consolidated Evergy for the three months ended and year to date September 30, 2017. (b) Certain Evergy, Westar Energy, and KCP&L as previously reported amounts have been adjusted to reflect reclassification adjustments made for comparative purposes as discussed further in Principles of Consolidation above and that have no impact on net income. Statement of Cash Flows In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments, which clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. Among other clarifications, the guidance requires that cash proceeds received from the settlement of corporate-owned life insurance (COLI) policies be classified as cash inflows from investing activities and that cash payments for premiums on COLI policies may be classified as cash outflows for investing activities, operating activities or a combination of both. Retrospective application is required. The Evergy Companies adopted the guidance effective January 1, 2018, which resulted in retrospective reclassification of cash proceeds of $1.9 million from the settlement of COLI policies from cash inflows from operating activities to cash inflows from investing activities for year to date September 30, 2017, for Evergy and Westar Energy. In addition, cash payments of $2.3 million for premiums on COLI policies were reclassified from cash outflows used in operating activities to cash outflows used in investing activities for the same period for Evergy and Westar Energy. The adoption of ASU No. 2016-15 did not have a material impact on KCP&L. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash, which requires that the statement of cash flows explains the change for the period of restricted cash and restricted cash equivalents along with cash and cash equivalents. The guidance requires a retrospective transition method and is effective for fiscal years beginning after December 15, 2017. The Evergy Companies adopted the guidance effective January 1, 2018. As a result, Evergy and Westar Energy adjusted amounts previously reported for cash and cash equivalents to include restricted cash which resulted in an increase to beginning and ending cash, cash equivalents and restricted cash of $0.1 million for year to date September 30, 2017. The adoption of ASU No. 2016-18 did not have a material impact on KCP&L. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires an entity that is a lessee to record a right-of-use asset and a lease liability for lease payments on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new guidance is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and requires a modified retrospective transition approach with an option to either adjust or not adjust comparative periods. The Evergy Companies plan to adopt the new guidance on January 1, 2019, without adjusting comparative periods. In 2016, management began evaluating current leases to assess the initial impact on Evergy's consolidated financial results. The Evergy Companies continue to evaluate the guidance and disclosure requirements and believe application of the guidance will result in an increase to the assets and liabilities on their consolidated balance sheets, with minimal impact to their consolidated statements of income and comprehensive income. In addition, management is evaluating the Evergy Companies' internal controls over financial reporting as needed to ensure that they remain effective after implementation. The standard permits an entity to elect a practical expedient for existing or expired contracts to forgo reassessing leases to determine whether each is in scope of the new standard and to forgo reassessing lease classification. The Evergy Companies expect to elect this practical expedient upon implementation. In July 2018, the FASB issued ASU No. 2018-11, which provides entities an optional transition method to apply ASU No. 2016-02 as of the date of initial application of the standard rather than as of the earliest period presented. The Evergy Companies are evaluating this update and have not yet determined if they will elect to use this optional transition method. Financial Instruments In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, which generally requires equity investments to be measured at fair value with changes in fair value recognized in net income. Under the new standard, equity securities are no longer to be classified as available-for-sale or trading securities. The guidance requires a modified retrospective transition method. This guidance is effective for fiscal years beginning after December 15, 2017; accordingly, the Evergy Companies adopted the new standard on January 1, 2018, without a material impact on their consolidated financial statements. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU No. 2014-09 one year, from January 1, 2017, to January 1, 2018. The ASU replaced most existing revenue recognition guidance in GAAP when it became effective. The Evergy Companies adopted ASU No. 2014-09 and its related amendments (ASC 606) on January 1, 2018, using the modified retrospective transition method for all contracts not completed as of the date of adoption. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while historical periods have not been adjusted and continue to be reported in accordance with the legacy guidance in ASC 605 - Revenue Recognition. There was no cumulative effect adjustment to the opening balance of retained earnings in 2018 for the Evergy Companies as a result of the adoption of the new guidance. The impact to both operating revenues and taxes other than income taxes on KCP&L's statements of comprehensive income in 2018 as a result of adopting ASC 606 was a decrease of $22.1 million and $59.7 million for the three months ended and year to date September 30, 2018, respectively. This impact was related to sales taxes and franchise fees collected from KCP&L's Missouri customers, which prior to ASC 606, were recorded gross on KCP&L's statements of comprehensive income. See Note 3 for more information on revenue from contracts with customers. |
