Dataset updated . Screening estimates derived from public data sources.
Organization records are derived from public infrastructure datasets (EIA, HIFLD, FCC, PNNL, county parcels, PeeringDB) and may be incomplete or lag operational changes. Owner/operator names are normalized for grouping; counts and capacities are catalogued estimates. Confirm ownership and availability directly with the organization.
