Output over time

Net generation · MWhElectricity produced after the plant’s own use. A negative value means it used more electricity than it produced.Definition ↗

Annual net generation · MWh. Bars below zero are negative net generation; a hollow mark means not reported. Missing years are not filled.

Why capacity and output differ: field note ↗

Ownership & operation

Ownership basisHow a generator's owners were established: from EIA-860's ownership schedule (reported), from EIA's rule that a unit absent from a complete schedule is wholly owned by its operator (derived), or unknown.Definition ↗

OperatorThe organization that runs a plant. It may have different owners.Definition ↗U.S. Army Corps of Engineers, Northwestern Division
OwnerAn organization with a reported share of a generator. Owned MW applies that share to operating nameplate capacity; it does not establish who buys the output.Definition ↗ Federally-owned utilityU.S. Army Corps of Engineers, Northwestern Division
2,184.8MW owned
