Sources and coverage Hydropower directories use registered plants in supported power markets. Pumped-storage operating roles and generation periods remain identified in the facility record.
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.
