The US is planning a lot more gas power – and data centers are the culprit. Proposed grid-connected gas capacity has nearly tripled since early 2023, while plans for new wind power are shrinking.

A new analysis and interactive map from Environment America Research & Policy Center and Frontier Group puts the planned gas buildout at 60.4 gigawatts (GW) through the end of 2030. That’s up 44% from the 41.8 GW expected in December 2025, based on filings submitted to the federal Energy Information Administration (EIA).

For perspective, that proposed new gas capacity alone exceeds the total generating capacity of every individual US state except Texas, California, and Florida, according to the groups.

These are planned projects, so the figures don’t mean all that capacity will get built. But they show how quickly the US power industry’s plans are shifting toward gas as electricity demand climbs.

Meanwhile, planned solar additions have stalled, and planned wind additions have dropped 33.9% since December 2025. Solar still leads the list of expected new generating capacity, but the groups warn that clean energy plans aren’t keeping pace with the data center boom.

“The data is clear: Surging electricity demand to power data centers is putting our nation’s transition to clean energy at risk,” said Andre Delattre, senior vice president and chief operating officer for The Public Interest Network. “Given the lifespans of new gas plants, these facilities could lock America into decades of continued fossil fuel dependence.
