Pacifico Energy GW Ranch

Last updated

Largest permitted data center campus in the US
Under construction

The biggest single power permit in US history, and it is Amazon's: an 8,000-acre off-grid Permian Basin campus authorized for 7.65 GW of gas generation, where Amazon holds the site and buys the power while Pacifico Energy builds the plant.

7.7 GWPlanned power
Developer
Pacifico Energy Group (power campus) · Amazon Data Services, Inc. (data center buildings)
Owner
Amazon Data Services, Inc. holds the site and the data center buildings; Pacifico Energy Group develops and owns the 7.65 GW generation campus
Tenant
Amazon (Amazon Data Services, Inc.): confirmed Aug 2026; takes power from Pacifico's on-site generation under a power purchase arrangement whose term, price and volume are undisclosed
Power detail
7.65 GW of gas-fired generation permitted (up to 35 turbines, simple-cycle), integrated with 1.8 GW of battery storage and 750 MW of solar; 5+ GW delivered to Amazon at full buildout. Off-grid today with no ERCOT interconnection, but Amazon states the campus is 'designed to transition to grid-connected service as interconnection timelines allow', so the off-grid design is no longer presented as permanent, though no interconnection request is on the record. Amazon also commits to non-potable water and custom low-water cooling, and to exploring beneficial use of produced water.
Power source
Fully off-grid private grid: natural gas turbines (small + large scale) + 750 MW solar + 1.8 GW BESS, no ERCOT connection; dedicated 15-mile, 1 BCF/d pipeline direct to the Waha Hub
Cooling
Not disclosed
Compute
