Subsequent Events [Abstract]
Subsequent Events	Subsequent Events. On October 24, 2022, we entered into an agreement to acquire two generating units at Washington County Power, a four-unit 660 megawatt combustion turbine generation and transmission facility located in Sandersville, Georgia, from Gulf Pacific Power, LLC, an investment fund managed by Harbert Management Corporation. The two acquired units will add approximately 330 megawatts of natural gas-fired capacity to our generation portfolio. This acquisition is subject to customary closing conditions, including regulatory approvals, and is expected to close in the fourth quarter of 2022.
