Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | Pay Versus Performance The information provided below is mandated by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, which require that we, among other things, report the amount of “compensation actually paid” to our named executive officers. These amounts are calculated in accordance with applicable SEC rules, and do not reflect the actual amount of compensation earned by or paid to our named executive officers during each applicable year. The guiding principles of our compensation philosophy are that pay should be linked to performance and that the interests of our executives and shareholders should be aligned. Our executive officers participate in incentive plans that contain a variety of performance measures that focus not only on financial performance, but also operational excellence, including measures linked to safety, reliability, customer satisfaction, climate, and reportable environmental events. Please refer to the Compensation Discussion and Analysis section of this proxy statement for details regarding how the Compensation and People Development Committee links the compensation paid to our named executive officers to our corporate performance. ​

​ (1) Compensation actually paid (“CAP”) was calculated by beginning with the total amount reported in the Summary Compensation Table (the “SCT”) for the applicable year, (i) subtracting the grant date fair value of stock awards reported in the Stock Awards column of the SCT (“Stock Awards”), (ii) subtracting the actuarial present value of the accumulated benefit under defined benefit plans reported in the Change in Pension Value and Nonqualified Deferred Compensation Earnings column of the SCT (“Change in Pension Value”), (iii) adding the change in fair value of stock awards for the applicable year, and (iv) adding the service cost and prior service cost for all defined benefit plans for the applicable year. Fair value amounts were computed in a manner consistent with the fair value methodology used to account for share-based payments in our financial statements under GAAP. The fair value amounts were calculated using our stock price on the last day of each fiscal year or the date of vesting, as applicable, and based upon the probable outcome of applicable performance conditions as of the last day of each fiscal year. The service cost and prior service cost for defined benefit plans were calculated using the same methodology as used for our financial statements under GAAP. Following is a reconciliation of the SCT total and the CAP for the CEO for each of the applicable years. Ms. Good is our CEO for each year reflected in columns (b) and (c). ​

Of the goals listed above, we consider adjusted EPS to be the most important financial performance measure (that is not otherwise required to be disclosed in the table) used to link executive compensation actually paid to company performance and therefore include it as the Company-Selected Measure in the table above. Adjusted EPS is a non-GAAP financial measure that represents basic and diluted EPS from continuing operations available to Duke Energy common shareholders, adjusted for the per share impact of special items. ​ |  |

Of the goals listed above, we consider adjusted EPS to be the most important financial performance measure (that is not otherwise required to be disclosed in the table) used to link executive compensation actually paid to company performance and therefore include it as the Company-Selected Measure in the table above. Adjusted EPS is a non-GAAP financial measure that represents basic and diluted EPS from continuing operations available to Duke Energy common shareholders, adjusted for the per share impact of special items. |  |
