The name on the permits is the small news. The delivery model is the story.
Amazon confirmed to ENR on August 11 that it owns GW Ranch, a hyperscale campus on roughly 8,000 acres in Pecos County, West Texas, developed by California-based Pacifico Energy Group. Amazon filed building permits with the Texas Department of Licensing and Regulation in August 2026 for three 189,000-sq-ft data center buildings, each estimated at about $300 million, scheduled for completion in December. Cleanview matched the filings to satellite imagery and state data before Amazon confirmed.
The power developer is the general contractor
Gensler is listed as design firm and didn’t respond to ENR. Pacifico says it will self-perform engineering, procurement and construction. No external prime has been publicly named on a campus of this scale.
That’s a structural statement about where behind-the-meter work is heading. When generation and compute get built as one asset, the entity that knows how to permit and build 35 turbines ends up holding the EPC, and the traditional prime contractor gets designed out of the org chart. Subcontractors bidding West Texas should assume their counterparty is Pacifico, not Amazon, and price the credit accordingly.
Off-grid first is the point
The campus holds state permits for 35 natural gas turbines producing up to 7.65 GW, with 750 MW of on-site solar and 1.8 GW of battery storage planned. This is Amazon’s first investment in a private behind-the-meter campus.
Building generation on site and connecting to the grid later routes around the ERCOT interconnection queue entirely. It also raises a live question about Governor Greg Abbott’s statewide data center pause, announced August 3 pending audits by two state energy regulators with no stated deadline. Amazon is among the companies that pledged compliance. How a pause on grid-connected development binds a campus that isn’t grid-dependent is not obvious.
The site sits about 30 miles from the off-grid Chevron and Microsoft complex, roughly 2.5 GW of gas expandable to 5 GW, due to start operating in 2028. West Texas is quietly becoming a cluster of privately generated compute.
The permit ceilings, stated as ceilings
Permitting documents cited by the Texas Observer authorize release of more than 12,000 tons per year of regulated air pollutants and up to 33 million tons per year of greenhouse gases. Those are permitted maximums, not projected actual emissions, and ENR states plainly that actual operating frequency is unknown. Rice University’s Baker Institute modeled gas burn at full capacity between 1 and 2 billion cubic feet a day, equal to 4% to 7% of all Permian Basin gas produced in 2025, also a full-capacity figure rather than an operating projection.
Three Senate Democrats sent Pacifico a letter in March seeking project detail. Terms of the Amazon and Pacifico power purchase agreement, including length, pricing and volumes, are not public.
Note on numbers: a $12 billion figure circulating on this project is Pacifico’s own February 2026 estimate of investment needed, given to Forbes. Neither Amazon nor Pacifico has disclosed a project cost.
