Missouri's generating fleet in context
Missouri's power plants hold 23.7 GW of nameplate capacity, the 21st-largest fleet among the 50 states and DC. This capacity — what the equipment could produce running flat out — differs from generation: a megawatt of solar and a megawatt of nuclear appear identical in these figures and produce very different amounts of electricity over a year.
Coal dominates the state's fleet at 40.7% of capacity, spread across 8 plants. Natural gas accounts for 26.1%, distributed among 34 plants. Wind carries 10.4% and solar 8.0%, though solar appears in 38 installations to wind's 14. The single nuclear plant, Callaway, represents 5.2% of capacity. Hydro and other sources round out the remainder.
The largest facilities are Labadie, a coal plant first online in 1970 with 2,389 MW, and Iatan, another coal station from 1980 with 1,754 MW. New Madrid coal plant, which came online in 1972, holds 1,300 MW. Callaway nuclear plant, commissioned in 1984, provides 1,236 MW. The oldest plant still listed is Niangua, which first came online in November 1930; the newest is Split Rail Solar Energy LLC, entering service in June 2026.
