Amazon is planning to build and operate a massive natural gas power plant in Pecos County, Texas, to supply electricity directly to an upcoming data center campus.
Scale of the Pecos County Power Plant and Emissions
The proposed West Texas facility utilizes 35 gas turbines to generate up to 7.65 gigawatts of electricity during peak demand, according to project details cited by E&E News. That output equals enough energy to power more than 1.9 million homes. Margaret Callahan, an Amazon spokesperson, confirmed that the tech giant is paying the full cost of powering its operations at the 8,000-plus acre site.
Texas environmental regulators approved air permits allowing the power generation portion of the campus to release over 33 million tons of carbon dioxide equivalent per year. That figure surpasses the emissions of the nation’s previously dirtiest coal plant, the James H. Miller Jr. Power Plant in Alabama, which recorded roughly 16 to 20 million tons of annual carbon dioxide emissions according to U.S. Energy Information Administration data.
The Shift Toward Off-Grid Energy Solutions
Technology companies are increasingly building dedicated on-site power generation to bypass lengthy wait times for grid connections. The Electric Reliability Council of Texas (ERCOT), which manages the state’s main power grid, is tracking over 438 gigawatts of requests for large loads, roughly 90 percent of which stem from data centers.
State leaders previously directed the Public Utility Commission of Texas and ERCOT to mandate that data centers reuse water, reduce local residential rate impacts, and pay for required transmission infrastructure.
By opting for an off-grid setup, Amazon’s Pecos County campus avoids waiting in the traditional utility queue. Callahan stated that the campus is designed to transition to grid-connected service as interconnection timelines allow. Similar off-grid projects are emerging across Texas, including a Fermi America gas power proposal near Amarillo and a 20-year agreement by Microsoft to purchase power from a 2.67-gigawatt natural gas facility in Reeves County developed by Chevron.
Environmental Impact and Corporate Climate Pledges
The reliance on fossil fuels for artificial intelligence infrastructure complicates corporate carbon targets. Under its Climate Pledge, Amazon has committed to achieving net-zero carbon emissions across its global operations by 2040. Company officials maintain that commitment, pointing to 10 gigawatts of carbon-free energy projects supported in Texas since 2010 alongside ongoing explorations for on-site solar energy and battery storage.
Luke Metzger, executive director of Environment Texas, stated that utilizing a giant new gas plant undermines corporate climate pledges and increases local air pollution compared to utilizing the ERCOT grid, which incorporates growing shares of wind, solar, and battery storage.
