(b)Excludes assets held for sale related to acquisition of Calpine. See Note 2 — Mergers, Acquisitions, and Dispositions for additional information.
The estimated useful lives of our generating facilities are based on a combination of depreciation studies, historical retirements, site licenses and management estimates of operating costs and expected energy market conditions. As a result of the acquisition of Calpine, we added a fleet of natural gas, oil, geothermal, battery storage and solar assets. There were no material changes in the estimated useful lives of our combined oil and gas, battery storage, wind and solar facilities as a result. Geothermal facility depreciation provisions are based on an estimated useful life through 2066. For additional information about the useful lives of our generating facilities and depreciation provisions see Note 8 — Property, Plant, and Equipment of our 2025 Form 10-K.
