Every project that wants to connect to the Texas grid joins ERCOT's interconnection queue. The queue is public. It says who wants to connect, how much, and in which county. It does not say how much room the grid has. A crowded county is a warning sign, not a closed door, and a quiet county is not a promise.
The queue
ERCOT's August 2026 Generation Interconnection Status report lists 1,751 projects totalling 432.6 GW. Voltane placed 1,403 of them (80%) at a substation or line: 807 with a confident match and 596 with a lower-confidence one. We could not place 348. The county comparison below uses the county ERCOT lists for every project, placed or not.
The land
Voltane's default Texas view holds 16,145 sites in 199 counties: sites large enough for 100 MW or more, within 10 miles of a 138 kV or higher line, inside ERCOT, and passing every exclusion (too small, too constrained, too much protected land).
Land without the crowd
67 counties have at least 100 of those sites. In 44 of them, at least 1,000 MW is already queued. In the other 23, less than 1,000 MW is queued, and they hold 3,264 sites, 20% of the view. Zavala County leads them with 204 sites and 692 MW queued, followed by Live Oak (187 sites) and Jackson (186).
Counties with 100 or more default-view sites and under 1,000 MW queued. Data (JSON)
At the other end, Pecos County has 20,699 MW queued against 445 sites, and Brazoria has 11,672 MW against 58.

How to read this
- Queued MW is a proxy for competition, never available capacity. Most queued projects never get built, and a county line says nothing about which substation has room.
- Indicative MW is land, not grid. It is the largest flat, unconstrained block on each site divided by 4.25 acres per MW.
- County totals hide geography. A large county can have a crowded substation on one side and open land on the other.
This is where we start a Texas search: find the land, then look at who else wants the same lines.
