US large load interconnection requests

535 large load interconnection requests are on file across the US grid, totalling 91.8 GW, as of 14 October 2026. These are requests to connect large new demand — data centers, industry, electrification — and they are tracked separately from the generation queue. 484 of the 535 state no end use at all, so most cannot honestly be attributed to any industry.

Coverage — read this before quoting the total

The markets below are the ones whose large-load queues we currently hold. ERCOT and PJM are not among them. Those are the two markets where most new US demand is actually arriving, so the national total on this page is a floor, not a ceiling. We would rather say that here than have the number quoted as complete.

What this dataset is, and what it is not

It is a normalised record of requests filed with transmission providers to connect large new demand, with the capacity requested, the filing date and the queue it sits in.

It is not a list of data centers. A request is not a building, a signed contract or a commitment to build, and most requests do not say what the load is for. It is also not a complete national picture — see the coverage note above.

It is not published anywhere else. The national interconnection dataset most often cited, Lawrence Berkeley National Laboratory’s Queued Up, covers generation and does not publish large-load queue data at all.
