What energy projects are proposed in Deaf Smith County?

ERCOT's September 2026 interconnection report lists 11 proposed energy projects in Deaf Smith County (6 solar, 3 wind, 1 battery storage and 1 gas), about 6,387 MW in all. 5 of the 11 have a signed interconnection agreement.

What stands out in Deaf Smith County

By capacity, solar leads in Deaf Smith County with 3,164 MW across 6 projects, followed by wind (3 projects, 1,740 MW) and gas (1 project, 1,275 MW). The largest single project is Aurelius 3 Natural Gas, a 1,275 MW gas engines project listed under IP Roman III Gas, LLC, still in study, and its target online date is Jun 2030. Of the 11, 6 are still in ERCOT's study process and 5 have posted security or started construction. Every listed connection point is on the 345 kV system (why the voltage matters). The single most-used connection point is 23908 Deaf Smith station 345 kV, shared by 3 projects. IP Roman III, LLC and IP Roman, LLC are each listed on 2 projects; 9 different companies appear in all. Target online dates for the projects not yet running span Oct 2027 to Jun 2030. All of them fall in ERCOT's Panhandle load zone.

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.

Crowded connection points in Deaf Smith County

Substations and switching stations named by two or more of the county's requests, matched on ERCOT's PSS/E bus number rather than the exact wording, so "60404 SOLSTICE", "AEP Solstice Substation #60404" and a tap off the Solstice line count together. Every request statewide that names the bus is listed; a request on a tap line counts toward both ends. Sharing a bus is not the same as sharing a study group, and ERCOT decides the latter.

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 Deaf Smith County

Texas has no state siting permit for solar or wind, and Texas counties generally have no zoning authority, so a project in Deaf Smith 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 Deaf Smith County connects to the grid

Deaf Smith County is on the ERCOT grid. The projects listed above are in ERCOT's Panhandle 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.
