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? 300+ markets scored daily by the Data Center Power Index, on live data from 7 US ISOs plus live Hydro-Québec and AESO (Alberta) feeds and modeled data for Nord Pool. Free, citable, with a live MCP server and CC-BY-4.0 data an LLM can both query and cite.

Each ISO's interconnection queue, with generation queues and load (demand) queues in separate columns — never added together.

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.
