AI Data Center Boom to Drive 44% Surge in US Gas-Fired Power Capacity

Data centers push gas capacity higher

According to a new analysis by the Environment America Research and Policy Center, electricity demand from AI data centers is rapidly expanding US gas-fired generation capacity. Gas capacity is expected to grow 44% over the next four years.

That amounts to roughly 20 gigawatts of additional capacity by 2030. The country's current gas capacity stands at 41.8 gigawatts, a level reached through centuries of infrastructure development.

Clean energy projects are being shelved

The analysis says the planned gas capacity expansion exceeds the combined output of every US state except Texas, California and Florida. Meanwhile, planned wind farm capacity has fallen 34% since December 2025.

Andre Delattre, chief operating officer for The Public Interest Network, says surging electricity demand to power data centers is putting the nation's clean energy transition at risk. He warns that the lifespans of new gas plants could lock the US into decades of fossil fuel dependence.

Gas plants wired directly to data centers aren't counted

Environment America's forecast does not account for gas plants that will be hooked up directly to data center facilities. Turbines powering Elon Musk's 1.2 gigawatt data center, for example, are affecting majority-Black communities in Memphis, Tennessee. The total capacity of such bolt-on plants is not clear.
