Arkansas's generating fleet in context
Arkansas holds 19.1 gigawatts of generating capacity, ranking 29th of the 50 states and DC. This figure represents nameplate capacity — what the equipment could produce running flat out — and differs from generation, the actual electricity produced over time, because a megawatt of solar and a megawatt of nuclear generate very different amounts over a year.
Natural gas and coal together dominate the fleet, supplying 37.6% and 28.7% respectively of the state's capacity across 18 and 5 plants. Solar accounts for 14.6% through 69 installations, while nuclear provides 9.6% from a single plant. Hydro and other sources make up the remainder, with wind contributing 0.8% and battery storage 0.2%. The five largest plants are Union Power Station, a natural gas facility with 2,428 megawatts; Arkansas Nuclear One at 1,845 megawatts; Independence Steam Electric Station and White Bluff, both coal plants with 1,800 megawatts each; and Magnet Cove, a natural gas plant with 746 megawatts.
The fleet spans a century of additions. The oldest plant on file, Remmel, first came online in January 1925, while the newest, SR Dumas, entered service in June 2026. Of 124 plants tracked, 123 remain in service.

Frequently asked questions
›How many power plants are there in Arkansas?
Arkansas has 124 operable power plants with a combined nameplate capacity of 19.1 GW, the 29th largest generating fleet of the 50 states and DC. 123 of them are currently in service.
›What is the largest power plant in Arkansas?
Union Power Station in Union County, a natural gas plant with 2,428 MW of capacity across 12 generating units, first online in January 2003.
›What fuel do Arkansas's power plants use?
Natural gas accounts for the largest share of Arkansas's generating capacity — 7,202 MW, or 37.6% of the total, across 18 plants. Coal follows at 28.7%, Solar follows at 14.6%, Nuclear follows at 9.6%. Note this is capacity, not generation — what the fleet could produce, not what it did.
›What is the oldest power plant in Arkansas?
Remmel is the oldest still operable, with its earliest unit entering service in January 1925. The most recent addition is SR Dumas, online since June 2026.
