Unknown 56 Sources and coverage Large-load records describe individual facilities and development scopes. Requested, contracted, planned, and operating power are distinct measures; figures at different scopes are not additive.
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.
