Proposed grid-connected gas power capacity in the United States is set to reach 60.4 gigawatts by the end of 2030. This figure represents a 44% increase compared to the 41.8 gigawatts projected in December 2025, according to data from the Energy Information Administration.
The surge in planned gas capacity is largely attributed to rising electricity demand from data centers. While gas projects are expanding, plans for new wind power capacity have declined by 33.9% since December 2025, and solar additions have stalled.
Texas leads the national expansion, accounting for 33.2% of the proposed new gas capacity. Other states with significant planned additions include Louisiana with 6.6 gigawatts, Pennsylvania with 4.4 gigawatts, Oklahoma with 3 gigawatts, and Mississippi with 2.6 gigawatts.
The reported figures may be conservative, as they exclude off-grid gas plants built to supply data centers directly. Analysts suggest these additional projects could contribute tens of gigawatts of power capacity beyond the current grid-connected estimates.
