United States · energy · register
Monthly inventory of US electric generators — operating, planned, retired and cancelled — reported by plant operators to the Energy Information Administration. Includes battery storage with nameplate power and, for some units, energy capacity in MWh. It is operator-reported inventory, not verified evidence, and it is preliminary: figures are revised in later editions.
