The recurring, machine-readable answer to the only question that matters for an AI build: where can you actually get power, and where can't you? 320 markets scored daily by the Data Center Power Index across 7 live US ISOs and 3 international grids. Free, citable, and the only data-center-intelligence source an LLM can both query and cite.

These are ISO-level totals. For the project-by-project view behind one of these rows — every queued generation and storage project with capacity, status and requested in-service date — open the ERCOT interconnection queue. Facility-side context for the same load lives on the US data center map.
The full physical stack for a site — power + fiber + substations + gas pipelines + water risk + interconnection queues + tax incentives — in one query.
