ERCOT · Large-load interconnection · the public record
439 gigawatts are waiting. 3.9 are live.
ERCOT's tracked large-load queue has grown roughly 11.5× since 2022 — to about 439 GW, around 87% data centers.[1] Of it, 9,042 MW are approved to energize and only 3,883 MW are observed operating[1] — a 0.9% funnel from request to reality. The only public record is aggregate PDF slide decks. lli-radar turns them into a dataset, a deadline clock, and a weekly digest. Everything is files in git; every number links to its source.
The line to plug into Texas, since 2022
Where the queue sits, by status tier
ERCOT has published LLI Queue Status decks since October 2022, but never a machine-readable series — NPRR1267 mandates the queue be published only as aggregate MW. This is that series, extracted deck by deck, each row carrying the source URL and the SHA-256 of the file it came from.
Requested is not built
Between a queue request and an operating load sit studies, agreements, security postings, transmission, and equipment. The gap between the three numbers below is the entire story the aggregate decks tell.
One linear scale, not a rendering error — approved-to-energize is 2.2% of requested MW, observed-operating 0.9%. Source: March 2026 TAC report; corroborated by ERCOT's April 2026 Texas Senate Business & Commerce testimony.
The Batch Zero clock
PGRR145/NPRR1325 replaces the serial study process with a batch: one submission window, one study, one MW allocation.[2] Miss the window and a project waits for Batch 1. The full table, fee math, and plain-English process live on the Batch Zero page.
