Confirmed facts. Pacifico Energy's GW Ranch is an off-grid power campus in Pecos County designed to serve hyperscale AI and high-performance computing load. The Texas Commission on Environmental Quality has issued an air-quality permit authorizing up to 7.65 GW of gas-fired generation — reported as the largest power-generation air permit granted in the United States. The published plan pairs that generation with approximately 1.8 GW of battery storage and 750 MWac of solar, operating as an integrated private grid rather than drawing capacity from ERCOT.
Current development stage. Air permit secured. Phase 1 is planned at 1 GW, with first power targeted for the first half of 2027. Permitting documents place the authorized envelope at more than 12,000 tons per year of regulated air pollutants and up to 33 million tons per year of greenhouse gases.
These are developer targets and a permitted ceiling — not completed or contracted capacity.
Key dependencies
- Firm, contracted gas deliverability at the volumes a multi-gigawatt fleet requires (analysis cited by the Texas Observer puts full-output consumption on the order of 1–2 Bcf/d)
- Generation equipment delivery slots
- Tenant offtake for phases beyond Phase 1
W Land note
An air permit of this size sets the regulatory ceiling a site may operate under; turbines, gas supply and offtake still have to be assembled underneath it. Read the 7.65 GW figure as runway, and the 1 GW Phase 1 as the near-term deliverable.
