Texas energy projects by the numbers

ERCOT's September 2026 interconnection report lists 1,789 proposed projects across 194 Texas counties, about 438,768 MW in all. ERCOT covers most of Texas; the Panhandle, parts of northeast and east Texas, and El Paso are on other grids and are not counted here.

610 solar projects, about 149,641 MW. The counties with the most proposed solar capacity are Pecos (8,875 MW), Wharton (3,874 MW), Borden (3,852 MW), Milam (3,396 MW), Brazoria (3,169 MW).

869 battery storage projects, about 157,258 MW, the largest category by count. The counties with the most proposed battery capacity are Harris (6,243 MW), Brazoria (5,747 MW), Bexar (4,983 MW), Wise (3,826 MW), Mitchell (3,824 MW). Some batteries are listed at 0 MW because they are sized below their site's total.

159 wind projects, about 48,395 MW. The counties with the most proposed wind capacity are Pecos (4,657 MW), Zapata (1,974 MW), Jim Hogg (1,746 MW), Brazoria (1,744 MW), Deaf Smith (1,740 MW).

By count: Pecos (57), Brazoria (56), Wharton (42), Harris (33), Milam (29). By capacity: Pecos (21,374 MW), Brazoria (11,487 MW), Wharton (8,625 MW), Wilbarger (8,506 MW), Reeves (8,350 MW).

The five largest by capacity: Brazos Energy Security (3,000 MW, gas combined cycle, Fisher); BM Great Rock Energy Center (1,981 MW, gas combined cycle, Leon); Prairie Ridge (Gas - CC) (1,660 MW, gas combined cycle, Franklin); Hecate Energy Orem Wind (1,542 MW, wind, Brazoria); Aegle Power (1,536 MW, gas combined cycle, Cameron).

497 have signed an interconnection agreement (323 of them have also posted financial security), 138 are under construction or approved for energization or synchronization, and 1,154 are still in study. See the stage definitions on the ERCOT page.

Compared with August: 27 projects are new, 48 are no longer listed, and 38 advanced a stage. The project-by-project lists are in the September 2026 update.

No. A listing means a developer asked ERCOT to study connecting the project to the grid. Many projects in study are never built, and ERCOT notes its report is built from developer-entered data for planning purposes and may contain errors. Projects further along, with a signed agreement, security posted, or construction under way, are more likely to proceed.

Every Texas county has a page listing its proposed projects, with developer, size, stage, and contacts: open the Texas counties page and pick your county. Got an offer on your land? Read how to check whether a project is real.
