Tennessee's generating fleet in context
Tennessee's power-plant fleet held 23.8 gigawatts of nameplate capacity across 108 plants as of August 2026, ranking 20th among the 50 states and DC. This is capacity — what the equipment could produce running flat out — not generation, which varies by fuel type and season.
Natural gas and coal carried roughly equal shares of the fleet, at 28.4% and 27% respectively, while nuclear plants added 21% and hydroelectric stations contributed 17.8%. Solar installations made up 5.2% of capacity, spread across 54 plants, with other fuels accounting for the remaining 0.6%. The five largest plants were Cumberland, a 2,600-megawatt coal station that came online in 1973; Watts Bar Nuclear Plant, producing 2,540 megawatts since 1996; Sequoyah, a 2,441-megawatt nuclear facility first online in 1981; Gallatin, a 1,918-megawatt coal plant dating to 1956; and Raccoon Mountain, a 1,714-megawatt hydro station that began operating in 1978.
The fleet spans more than a century of power-plant construction. Ocoee 1, a hydroelectric station, came online in January 1912 as the oldest plant still listed, while the newest addition, SR Adamsville, entered service in July 2026.
