Microsoft and Chevron are planning one of the largest gas-fired data center projects in the United States

Microsoft and Chevron on Monday announced plans to develop a 2.67 gigawatt natural gas-fired power plant in West Texas to serve the technology company’s cloud data and artificial intelligence centers.

Under a 20-year power purchase agreement, the plant will provide electricity for a data center operated by Microsoft. Two large GE Vernova turbines will generate most of the power, while Caterpillar’s Solar Turbines will provide the rest. (The name solar turbines may sound familiar; xAI uses them at its unlicensed power plant near Memphis.) Microsoft will buy energy from the power plant for 20 years.

The project will be “among the largest data center and natural gas power development projects in the United States,” Chevron said in a press release.

Although Microsoft has been announcing the move for months, it still represents a major shift for a company that has been vocal about its sustainability efforts. Microsoft has pledged to eliminate carbon emissions by 2030, a goal that will be difficult to achieve with this new power plant.

The Kilby Project, as the power plant is known, would likely release more than 13 million tons of carbon dioxide, 3,200 tons of standard air pollutants and 278,000 pounds of hazardous air pollutants, according to the Environmental Integrity Project.
