Tennessee's generating fleet in context
Tennessee's generating fleet holds 23.7 GW of nameplate capacity — what the equipment could produce running flat out, not what it actually generated — and ranks 20th among the 51 state fleets. The fleet comprises 106 plants, all in service as of May 2026.
Natural gas and coal each carry roughly a quarter of the state's capacity at 28.5% and 27%, respectively, with 6,761 MW and 6,413 MW across 12 and 4 plants. Nuclear plants account for 21% at 4,981 MW across 2 units, while hydroelectric dams contribute 17.8% from 29 plants totaling 4,234 MW. Solar installations make up 5.1% of capacity at 1,211 MW spread across 52 plants, and other fuels add 0.6%. The five largest plants are Cumberland at 2,600 MW of coal capacity, Watts Bar Nuclear Plant at 2,540 MW, Sequoyah at 2,441 MW of nuclear capacity, Gallatin at 1,918 MW of coal, and Raccoon Mountain at 1,714 MW of hydro.
The fleet spans nine decades, from Calderwood, first online in April 1930, to Graceland Solar, LLC, which came online in May 2026.
