Pay vs Performance [Table Text Block] | Pay vs. Performance To comply with Item 402(v) of Regulation S-K, we are providing the following information. The Pay vs. Performance (“PVP”) table below provides the “compensation actually paid” ​(“CAP”) to the Company’s CEO and the average CAP for non-CEO NEOs. CAP represents a new calculation of compensation that differs from the total compensation reported in the Summary Compensation Table (“SCT”). You should refer to the “Compensation Discussion and Analysis” section above for discussion regarding how the Company’s compensation program is designed to align with the Company’s performance and long-term shareholder interests.

Compensation Actually Paid vs. Company Selected Measure [Text Block] | Relationship Between Compensation Actually Paid and Performance Measures in the PVP Table The most important annual financial measure that the Company uses to link pay to performance is the Company’s annual EPS, which is not only the most heavily weighted metric in the STIP, but also correlates to the Company’s TSR, which is the most heavily weighted performance metric in the Company’s LTIP. As shown in the chart below, the Company’s EPS increased by 9.7% between 2020 and 2021, while the CEO and Average NEO CAP decreased by 10% and 14.9%, respectively, for the same period. In 2022, while the Average NEO CAP increased by 5.3% and the CEO CAP decreased by 37.9%, driven primarily by the appointment of a new CEO effective January 1, 2022, the Company’s EPS increased by 7.8%. During the same three-year period (2020 – 2022), the Company’s Cumulative TSR was 25.2% and the Company’s net income increased by 23.3%. In addition, Ameren has consistently outperformed the S&P 500 Utilities Index for the reported periods. The value of an initial fixed $100 investment based on the Company’s cumulative TSR was 3.8, 3.8 and 5.1 percentage points above the S&P 500 Utilities Index TSR in 2020, 2021, and 2022, respectively. |  |  |
Tabular List [Table Text Block] | Additional Company-Selected Performance Measures The following table represents the unranked list of the most important performance measures the Company used to align compensation actually paid to the CEO and NEOs for 2022 to Company performance. While these performance measures are the most important measures, additional financial and other measures were also considered to align the CEO and NEOs’ pay and performance as further described in the “Compensation Discussion and Analysis” section above.

These measures generally reflect those used internally to measure Company performance and externally to report to investors, and taken together they provide a holistic measure of Company growth, shareholder value and overall financial performance, as well as progress toward transitioning to clean energy through the addition of renewable generation, energy storage and the retirement of coal-fired energy centers. |  |  |

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -URI https://asc.fasb.org/extlink&oid=128089324&loc=d3e5070-113901 + Details
