| Pay vs Performance [Table Text Block] | | Pay Versus Performance As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) and certain measures of the financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to the Compensation Discussion and Analysis beginning on page 65.

Akins for each of the years shown. Mr. Akins was the Company’s Chair, President and CEO for 2020 until August 10, 2022, when he became Chair and CEO. Effective January 1, 2023, Mr. Akins became Executive Chair. The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Akins for each corresponding year in the “Total” column of the Summary Compensation Table (“SCT”). Refer to the SCT in the proxy statement for each year for further information. (2) The dollar amounts reported in column (c) represent the amount of “compensation actually paid” or “CAP” for Mr. Akins, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Akins during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Akins’ Total Compensation shown in the SCT for the applicable year to calculate “CAP”: Reported Summary Compensation Table Total Reported Stock Awards (A) Equity Award Adjustments (B) Reported Change in Pension Value (C) Pension Benefit Adjustments (D) Operating Earnings Per Share(8) Year 2022 $ 16,375,508 $ (10,824,690) $ 15,998,849 $ (204,063) $ 172,510 $ 5.09 2021 $ 15,051,215 $ (9,976,149) $ 13,937,070 $ (461,732) $ 169,089 $ 4.74 2020 $ 15,503,434 $ (9,615,116) $ 5,206,247 $ (698,612) $ 151,867 $ 4.44 (A) This column reflects the total grant date fair value of equity awards reported in the “Stock Awards” column in the SCT for the applicable year. Mr. Akins did not receive option awards in the years shown. (B) The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: i. The year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; ii. The amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; iii. For awards that are granted and vest in same applicable year, of which there were none for Mr. Akins, the fair value as of the vesting date; iv. For awards granted in prior years that had all applicable vesting conditions satisfied in the applicable year, the change in fair value as of the vesting date (from the end of the prior fiscal year); v. For awards granted in prior years that are determined to permanently not meet the applicable vesting conditions during the applicable year, of which there were none for Mr. Akins, a deduction equal to the fair value at the end of the prior fiscal year; and vi. The dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year[, of which there were none for Mr. Akins]. The valuation methodology used to determine valuation assumptions and calculate fair values for the TSR portion of the Company’s performance units were consistent with those previously disclosed for the calculation of grant date values and were calculated in accordance with FASB ASC Topic 718 by an independent third party. See Note 15 to the Consolidated Financial Statements included in our Form 10-K for the applicable year for a discussion of the relevant assumptions used in calculating the grant date fair values of equity awards. The EPS and non-emitting generating capacity measures in the Company’s performance shares were valued using target scores as of the grant date, the Company’s projected score for each measure for valuation dates within the performance period, and the actual score for vested awards. These scores were multiplied by the closing share price of AEP common stock on the vesting date or at year end, as applicable, and by number of shares or units then outstanding associated with the weight assigned to each performance measure, including shares or units due to dividend credits. The prorated portion of performance shares that vest due to the elimination of an executive’s position and separation from AEP service as the result of a consolidation, reorganization, restructuring or downsizing or under circumstances that give rise to Executive Severance Plan Benefits are treated as unvested until the end of the performance period for the purpose of calculating “CAP”. The amounts deducted or added in calculating the equity award adjustments are as follows: Year End Fair Value of Equity Award Granted in Year Shown Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year Year over Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation Total Equity Award Adjustments Year 2022 $ 14,002,330 $ 1,846,351 $ — $ 150,168 $ — $ — $ 15,998,849 2021 $ 12,066,172 $ 371,547 $ — $ 1,499,351 $ — $ — $ 13,937,070 2020 $ 7,977,798 $ (1,451,439) $ — $ (1,320,113) $ — $ — $ 5,206,247 (C) The amounts included in this column are the Change in Pension Value amounts reported in “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column of the SCT for the applicable year. Mr. Akins did not receive preferential or above-market earnings on deferred compensation for any of the years shown. (D) The total pension benefit adjustment for each applicable year includes the aggregate of two components: (i) the actuarially determined service cost for services rendered by Mr. Akins during the applicable year (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during the applicable year that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”), of which there were none. In each case, the adjustments are calculated in accordance with U.S. GAAP. The amounts deducted or added in calculating the pension benefit adjustments are as follows: Year / Plan Service Cost Prior Service Cost Total Pension Benefit Adjustments 2022 AEP Retirement Plan $ 23,676 $ — $ 23,676 CSW Executive Retirement Plan $ 148,834 $ — $ 148,834 2022 Total $ 172,510 $ — $ 172,510 2021 AEP Retirement Plan $ 23,999 $ — $ 23,999 CSW Executive Retirement Plan $ 145,090 $ — $ 145,090 2021 Total $ 169,089 $ — $ 169,089 2020 AEP Retirement Plan $ 22,979 $ — $ 22,979 CSW Executive Retirement Plan $ 128,888 $ — $ 128,888 2020 Total $ 151,867 $ — $ 151,867 (3) The dollar amounts reported in column (d) represent the average of the amounts reported for the Company’s named executive officers (NEOs) as a group (excluding Mr. Akins) in the “Total” column of the SCT in the applicable year. Refer to the SCT in the proxy statement for each year for further information. The names of each of the NEOs (excluding Mr. Akins) included for purposes of calculating the average amounts in each applicable year are as follows: 2022: Julia A. Sloat, Ann P. Kelly, David M. Feinberg, Charles E. Zebula, Paul Chodak III, and Lisa M. Barton 2021: Julia A. Sloat, Lisa M. Barton, David M. Feinberg, Charles E. Zebula, Brian X. Tierney, and Mark C. McCullough 2020: Brian X. Tierney, Lisa M. Barton, David M. Feinberg, and Lana L. Hillebrand (4) The dollar amounts reported in column (e) represent the average amount of “CAP” to the NEOs as a group (excluding Mr. Akins), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Mr. Akins) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Mr. Akins) for each year to determine the “CAP”, using the same methodology described above in Note 2: Average Reported Summary Compensation Table Total for Non-PEO NEOs Average Reported Value of Stock Awards Average Equity Award Adjustments (A) Average Reported Average Pension Benefit Adjustments (B) Average Compensation Actually Paid “CAP” to Non-PEO NEOs Year 2022 $ 3,069,010 $ (1,896,237) $ 2,019,808 $ (2,514) $ 55,520 $ 3,245,587 2021 $ 3,372,510 $ (1,903,587) $ 1,517,671 $ (63,057) $ 55,056 $ 2,978,593 2020 $ 3,975,937 $ (1,745,503) $ 709,359 $ (278,008) $ 63,130 $ 2,724,914 (A) The amounts deducted or added in calculating the total average equity award adjustments are as follows: Year Average Year End Fair Value of Equity Award Year over Year Average Change in Fair Value of Outstanding and Unvested Equity Awards Average Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year Year over Year Average Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year Average Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year Average Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation Total Average Equity Award Adjustments 2022 $ 1,916,756 $ 222,215 $ 28,346 $ 36,593 $ (184,101) $ — $ 2,019,808 2021 $ 1,487,311 $ 48,144 $ 215,087 $ 222,189 $ (455,060) $ — $ 1,517,671 2020 $ 1,344,554 $ (357,232) $ 125,000 $ (278,587) $ (124,375) $ — $ 709,359 (B) The amounts deducted or added in calculating the total pension benefit adjustments are as follows: Year / Plan Average Service Cost Average Prior Service Cost Average Total Pension Benefit Adjustments 2022 AEP Retirement Plan $ 15,227 $ — $ 15,227 AEP Supplement Benefit Plan $ 40,293 $ — $ 40,293 2022 Total $ 55,520 $ — $ 55,520 2021 AEP Retirement Plan $ 12,220 $ — $ 12,220 AEP Supplement Benefit Plan $ 42,836 $ — $ 42,836 2021 Total $ 55,056 $ — $ 55,056 2020 AEP Retirement Plan $ 14,110 $ — $ 14,110 AEP Supplement Benefit Plan $ 49,020 $ — $ 49,020 2020 Total $ 63,130 $ — $ 63,130 (5) Total shareholder return (TSR) reflects the value at the end of the year shown of $100 invested in the Company’s common stock at the closing market price on the last trading day immediately prior to first year shown. This provides a cumulative TSR value that incorporates both the appreciation or depreciation of the Company’s stock price and the value of dividends, which are assumed to have been reinvested in additional AEP shares. TSR for this purpose was calculated and provided by Bloomberg L.P. as of December 31, 2022. Past performance is not a guarantee of future results. (6) Represents the market-capitalization weighted average TSR of the S&P Electric Utilities (SP833) that was also used for the stock performance graph required by Item 201(e) of Regulation S-K in our Annual Report for the year ended December 31, 2022. This is an index of peer companies provided by S&P Dow Jones Indices LLC for which the TSR was calculated and provided by Bloomberg L.P. as of December 31, 2022. (7) The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year. (8) Operating earnings per share is a non-GAAP financial measure. Exhibit A to the proxy statement for the corresponding year contains a full reconciliation of GAAP earnings per share to non-GAAP operating earnings per share for that year. For purposes of Item 402(v) of Regulation S-K, the Company has determined that operating earnings per share is the financial performance measure that, in the Company’s assessment, represents the most important performance measure used by the company to link “CAP” of the Company’s NEOs to Company performance for the most recent fiscal year. This performance measure may not have been the most important financial performance measure for 2021 and 2020 and the Company may determine a different financial performance measure to be the most important financial performance measure in future years. | | |

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | | “CAP” vs. AEP TSR As shown in the chart below, as AEP’s TSR increased from 2020 through 2022, “CAP” also increased, particularly for the PEO, which shows the directional alignment of “CAP” with TSR. This alignment is due primarily to the use of equity incentives, the value of which is denominated in AEP stock and thereby directly tied to AEP’s TSR. In addition, performance shares and a substantial portion of short-term incentive compensation are tied to performance measures that we believe are directionally aligned with the value that AEP provides to shareholders while further encouraging TSR through incentive compensation leverage. For example, performance that would drive an x% increase in stock price might drive a 2x% increase in “CAP” through such leverage. Such incentive leverage increases the incentive for executives to produce strong performance on metrics that drive TSR. | | |
| Compensation Actually Paid vs. Net Income [Text Block] | | “CAP” vs. Net Income As shown in the chart below, the amount of “CAP” for Mr. Akins and the average amount of “CAP” for the Company’s NEOs as a group (excluding Mr. Akins) is aligned with the Company’s net income for 2020 and 2021 but not for 2023. This is because the Company uses operating earnings per share, not net income, as the primary measure of the Company’s earnings performance in its executive compensation program. Therefore, when operating earnings per share and net income diverge, as happened in 2022, “CAP” will be aligned with operating earnings per share and not net income. The Company does not use net income as a performance measure, in part, because the Company believes operating earnings per share is a measure upon which management’s actions have a more significant impact and, therefore, it is a better measure of the performance of management and the Company. Operating earnings per share also better reflects the Company’s future earnings capacity and is more closely aligned with the Company’s TSR. | | |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | | “CAP” vs. AEP Operating Earnings Per Share As shown in the chart below, AEP’s operating earnings per share is well aligned with “CAP”. This is because 50% of long-term incentive compensation and 60% of short-term incentive compensation are tied to achievement of operating earnings per share objectives over a three- and one- year period, respectively. The HR Committee assigned these substantial incentive compensation weights to operating earnings per share, in part, because it is a measure upon which management’s actions have significant impact, and it reflects the achievement of the Company’s earnings growth targets, which are a primary driver of the Company’s stock price and TSR. | | |
| Total Shareholder Return Vs Peer Group [Text Block] | | Total Shareholder Return (TSR): AEP vs. Industry Peer Index (S&P Electric Utilities) As shown in the chart below, AEP’s 3-year cumulative TSR lagged our industry peers during the 2020 through 2022 period. TSR was nearly flat for our industry peers overall for 2020, largely due to the impact of COVID-19 on economic conditions and the uncertainty this created. AEP’s TSR improved more than that of the S&P Electric Utilities during 2022, erasing a significant portion of the cumulative TSR disparity. | | |

| [1]“PEO” means Principal Executive Officer, which was Nicholas K. Akins for each of the years shown. Mr. Akins was the Company’s Chair, President and CEO for 2020 until August 10, 2022, when he became Chair and CEO. Effective January 1, 2023, Mr. Akins became Executive Chair. The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Akins for each corresponding year in the “Total” column of the Summary Compensation Table (“SCT”). Refer to the SCT in the proxy statement for each year for further information.[2]The dollar amounts reported in column (c) represent the amount of “compensation actually paid” or “CAP” for Mr. Akins, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Akins during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Akins’ Total Compensation shown in the SCT for the applicable year to calculate “CAP”: Reported Summary Compensation Table Total Reported Stock Awards (A) Equity Award Adjustments (B) Reported Change in Pension Value (C) Pension Benefit Adjustments (D) Operating Earnings Per Share(8) Year 2022 $ 16,375,508 $ (10,824,690) $ 15,998,849 $ (204,063) $ 172,510 $ 5.09 2021 $ 15,051,215 $ (9,976,149) $ 13,937,070 $ (461,732) $ 169,089 $ 4.74 2020 $ 15,503,434 $ (9,615,116) $ 5,206,247 $ (698,612) $ 151,867 $ 4.44 (A) This column reflects the total grant date fair value of equity awards reported in the “Stock Awards” column in the SCT for the applicable year. Mr. Akins did not receive option awards in the years shown. (B) The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: i. The year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; ii. The amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; iii. For awards that are granted and vest in same applicable year, of which there were none for Mr. Akins, the fair value as of the vesting date; iv. For awards granted in prior years that had all applicable vesting conditions satisfied in the applicable year, the change in fair value as of the vesting date (from the end of the prior fiscal year); v. For awards granted in prior years that are determined to permanently not meet the applicable vesting conditions during the applicable year, of which there were none for Mr. Akins, a deduction equal to the fair value at the end of the prior fiscal year; and vi. The dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year[, of which there were none for Mr. Akins]. The valuation methodology used to determine valuation assumptions and calculate fair values for the TSR portion of the Company’s performance units were consistent with those previously disclosed for the calculation of grant date values and were calculated in accordance with FASB ASC Topic 718 by an independent third party. See Note 15 to the Consolidated Financial Statements included in our Form 10-K for the applicable year for a discussion of the relevant assumptions used in calculating the grant date fair values of equity awards. The EPS and non-emitting generating capacity measures in the Company’s performance shares were valued using target scores as of the grant date, the Company’s projected score for each measure for valuation dates within the performance period, and the actual score for vested awards. These scores were multiplied by the closing share price of AEP common stock on the vesting date or at year end, as applicable, and by number of shares or units then outstanding associated with the weight assigned to each performance measure, including shares or units due to dividend credits. The prorated portion of performance shares that vest due to the elimination of an executive’s position and separation from AEP service as the result of a consolidation, reorganization, restructuring or downsizing or under circumstances that give rise to Executive Severance Plan Benefits are treated as unvested until the end of the performance period for the purpose of calculating “CAP”. The amounts deducted or added in calculating the equity award adjustments are as follows: Year End Fair Value of Equity Award Granted in Year Shown Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year Year over Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation Total Equity Award Adjustments Year 2022 $ 14,002,330 $ 1,846,351 $ — $ 150,168 $ — $ — $ 15,998,849 2021 $ 12,066,172 $ 371,547 $ — $ 1,499,351 $ — $ — $ 13,937,070 2020 $ 7,977,798 $ (1,451,439) $ — $ (1,320,113) $ — $ — $ 5,206,247 (C) The amounts included in this column are the Change in Pension Value amounts reported in “Change in Pension Value and Nonqualified Deferred Compensation Earnings” column of the SCT for the applicable year. Mr. Akins did not receive preferential or above-market earnings on deferred compensation for any of the years shown. (D) The total pension benefit adjustment for each applicable year includes the aggregate of two components: (i) the actuarially determined service cost for services rendered by Mr. Akins during the applicable year (the “service cost”); and (ii) the entire cost of benefits granted in a plan amendment (or initiation) during the applicable year that are attributed by the benefit formula to services rendered in periods prior to the plan amendment or initiation (the “prior service cost”), of which there were none. In each case, the adjustments are calculated in accordance with U.S. GAAP.
