Power Plants in Texas

Texas holds 204.9 GW of generating capacity, ranking first of the 50 states and DC. This capacity is measured as nameplate capacity — what the equipment could produce running flat out, not what it actually generates, which varies widely by fuel type and season.

Natural gas and wind together carry most of the fleet. Natural gas accounts for 40.7% of capacity across 312 plants, while wind provides 21.9% across 230 plants. Solar adds 17.5% across 242 plants, coal represents 8.7% across 12 plants, and battery storage holds 7.6% across 226 plants. Nuclear, hydro, and other sources make up the remainder. The largest single plant is W A Parish, a coal facility with 4,008 MW first online in 1958. South Texas Project, a nuclear station, ranks second at 2,709 MW, followed by Comanche Peak at 2,430 MW also nuclear. Martin Lake, a coal plant with 2,380 MW, and Forney Energy Center, a natural gas facility with 1,894 MW first online in 2003, round out the five largest.

The fleet spans nearly a century of technology. The oldest plant listed, Dunlap TP 1, came online in January 1927. The newest, Hubbard Wind II, entered service in August 2026. The 1,095 plants tracked include everything down to sub-megawatt backup generators, so the count does not reflect the size of the fleet — capacity is the meaningful measure of that.
