Natural gas in the US fleet

The United States has 2,011 natural gas plants with a combined nameplate capacity of 587.4 GW as of August 2026. This capacity represents 41.6% of all US generating capacity. Gas-fired plants serve as the swing supply on most American grids, available to ramp up when demand rises or other sources fall short.

The fleet is concentrated but not extreme. Texas leads with 83,458 MW across 312 plants, accounting for 14.2% of the national total and 40.7% of its own state's capacity. Florida, California, Pennsylvania, New York, and Louisiana follow, together holding a substantial share. Just eight states hold half the total capacity, yet plants exist in 49 of the 50 states and DC, spreading the fleet across most of the country.

The largest plant is West County Energy Center in Florida at 4,263 MW, followed by Crystal River, also in Florida, at 3,449 MW. Barry in Alabama and Manatee in Florida round out the top five. The oldest gas plant still listed came online in January 1912 at Georgia-Pacific's Nekoosa Mill in Wisconsin; the newest, Bos Dairy in Indiana, started in August 2026.
