Sources and coverage

Plant inventory comes from the source-backed registries in supported power markets. Capacity is reported nameplate MW; it is separate from generation in MWh.

Geographic directories use the state and city recorded for each asset. Organization groups preserve published names and roles. Utility groups use the utility named in the facility record; individual profiles distinguish service agreements from service-territory matches. Each profile carries the sources and dates behind its facts.
