What energy projects are proposed in Culberson County?

ERCOT's September 2026 interconnection report lists 4 proposed energy projects in Culberson County (3 solar and 1 wind), about 1,328 MW in all. 1 of the 4 has a signed interconnection agreement. 1 is new since August.

What stands out in Culberson County

By capacity, wind leads in Culberson County with 740 MW across 1 project, followed by solar (3 projects, 588 MW). The largest single project is Buffalo Jump Wind, a 740 MW wind project listed under BOULEVARD ASSOCIATES, LLC, still in study, and its target online date is Jul 2029. Of the 4, 3 are still in ERCOT's study process and 1 has posted security or started construction. Connection points are mostly at 138 kV (2 projects) and 345 kV (1 project) (why the voltage matters). Each of the 4 projects is listed under a different company. Target online dates for the projects not yet running span May 2027 to Jul 2030. All of them fall in ERCOT's West load zone. 1 is new since August and 1 that was listed in August has since dropped off.

A listing is a request to study a grid connection, not a built project; the stage column says how far each one has gone.

Stage, most advanced first: Approved for synchronization (first power) · Approved for energization (backfeed) · Under construction · Signed; security posted (interconnection agreement signed and financial security posted) · Signed (agreement signed, security not yet posted) · In study (screening or full interconnection study, no agreement). A target date that has already passed is marked; ERCOT keeps the developer's last reported date until the developer changes it.

No longer listed since August

These projects were in ERCOT's August interconnection report but are not in its September 2026 report. ERCOT's reports do not say why a project leaves the list.

What the stages and dates mean: how to read ERCOT's report. ERCOT's report lists self-limiting facilities (batteries that limit injection below nameplate) at 0 MW; repowers of existing plants show 0 with no capacity change. "Approved for energization" and "approved for synchronization" are ERCOT's own milestones (backfeed, then first power). "Shared with N other requests" counts active requests anywhere in ERCOT naming the same point of interconnection, matched on ERCOT's exact wording, so a bus written two ways counts as two points.

Permits and reviews for Culberson County

Texas has no state siting permit for solar or wind, and Texas counties generally have no zoning authority, so a project in Culberson County is shaped by site control, the county road use agreement, tax agreements, and the grid connection (what still applies · the twelve approvals, stage by stage). Wetland, endangered species, historic, and FAA reviews depend on the site: statewide and federal contacts · decommissioning law.

How a project in Culberson County connects to the grid

Culberson County is on the ERCOT grid. The projects listed above are in ERCOT's West load zone. The serving utility handles the connection request. Interconnection by market and utility · what ERCOT is.

How long it takes. ERCOT staff put the connection process at 18 to 30 months for generation of 10 MW or more, before construction or supply delays (ERCOT, Oct. 2024). Across the U.S., the median project built in 2025 took 61 months from interconnection request to commercial operation (Berkeley Lab, Queued Up 2026), so a lease signed today usually means construction years out: timelines by market.
