POWER & FACILITY EVIDENCE

Power and Facility Evidence Database

Review power assets, contract observations, facility specifications and relationships from public sources.

This partial collection preserves source-level observations. Generation and registered connection capacity are distinct from spare supply capacity for data centers. Planned dates and contract announcements do not confirm energization or supply commencement.
