Starr County, Texas: solar, wind, and storage permits
Who to call and what to check for a solar, wind, or battery storage project in Starr County. Texas has no statewide siting permit for solar or wind, so the key contacts are the appraisal district, state environmental offices, the grid operator, and the county itself.
Who handles property records and taxes in Starr County?
The Starr County appraisal district keeps parcel records and decides agricultural or wildlife valuation, which a solar or storage lease can end, triggering rollback taxes. The Texas Comptroller lists the district's and the county tax office's phone, email, address, and website, plus local taxing districts such as groundwater conservation districts.

Does Starr County have zoning or a solar permit?
Texas counties generally do not have zoning authority, and the state has no siting permit for solar or wind generation. Projects are usually shaped instead by site control, road use agreements with the county, tax agreements, and utility interconnection. If the county takes part in FEMA's flood insurance program, its floodplain administrator issues development permits in mapped flood zones. Ask the county judge's office or commissioners court about road use and any local requirements.

Stage: In study means ERCOT is still studying the connection; Signed means the interconnection agreement is signed; security posted means the developer has also posted financial security and a notice to proceed; Energized and Approved to connect mean ERCOT has approved the project to energize or synchronize with the grid. "Self-limiting" batteries are reported as 0 MW because they are sized below the site's total capacity. Source: ERCOT Generator Interconnection Status (GIS) Report, August 2026. ERCOT prepares this report for planning purposes from data entered by developers and transmission providers, and notes it may contain errors or be out of date.
