Totals only include facilities with a reported or estimated figure; most sites don't disclose power, so these are floors, not market size estimates. Online = operating sites; pipeline = remaining planned MW at sites under construction or planned. Average industrial electricity price: 9.35¢/kWh (EIA).

Power reality
Announced capacity vs. what grid records, construction and operation document. Facility-level sums; sources differ in coverage.
- Announced267 MW
- Interconnection requests—
- Contracted / approved300 MW
- Under construction190 MW

Bucketed by the midpoint of each site's evidence-based window. Windows are ranges, not forecasts.
No large gaps in this scope.
Interconnection queues
Active requests to connect to the grid (CAISO). Requests are applications, not commitments — most never get built.
