Summary
San Antonio has no ordinance targeting cryptocurrency mining. Facilities are allowed by right in nonresidential zoning like any data-processing use. The only mandatory rule is Texas's requirement that large miners over 75 megawatts register with the state utility commission.
"Virtual currency mining facility" means a facility that uses electronic equipment to add virtual currency transactions to a distributed ledger. (b) The commission by rule shall require a person operating a virtual currency mining facility who enters into an agreement for retail electric service in the ERCOT power region to register the facility receiving service as a large flexible load under this section if: (1) the facility requires a total load of more than 75 megawatts; and (2) the facility load is interruptible.
Full Breakdown
Texas Utilities Code Section 39.360, added by Senate Bill 1929 (effective September 1, 2023), governs crypto mining across the ERCOT grid that powers San Antonio. A 'virtual currency mining facility' drawing more than 75 megawatts of interruptible retail power must register with the Public Utility Commission of Texas within one business day of starting service, reporting its location and five-year anticipated demand. San Antonio's Unified Development Code adds no crypto-specific standard; mining sites sit in nonresidential districts as a general data-processing use. City-proposed 1,000-foot data-center buffers from homes were not adopted as of July 2026.
Violations & Fines
Running a 75-plus-megawatt mining facility on the ERCOT grid without registering with the Public Utility Commission violates state law; the PUCT's implementing rule treats non-registration as a Class A violation carrying penalties up to $25,000 per day.
