Guadalupe County, Texas: solar, wind, and storage permits
Who to call and what to check for a solar, wind, or battery storage project in Guadalupe 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 Guadalupe County?
The Guadalupe 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 Guadalupe 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.
What energy projects are proposed in Guadalupe County?

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for planning purposes from data entered by developers and transmission providers, and notes it may contain errors or be out of date.

How does a project here connect to the grid?
Most of Texas is on the ERCOT grid, but parts of the Panhandle and northeast Texas are in SPP, parts of east Texas are in MISO, and El Paso is in the western grid. The serving utility decides which process applies.

What state and federal reviews can apply?
Depending on the site: wetland permits from the U.S. Army Corps of Engineers, endangered species review through U.S. Fish and Wildlife, historic review through the Texas Historical Commission, wildlife comments from Texas Parks and Wildlife, and FAA notice for tall structures like wind turbines.
