About electricity rates in Missouri
Missouri has a regulated market with no retail choice. Ameren Missouri serves St. Louis and much of eastern Missouri, Evergy serves the Kansas City area and the west, and Liberty serves the southwest around Joplin, all regulated by the Missouri Public Service Commission. Electric cooperatives supplied by Associated Electric Cooperative serve most rural areas, and cities such as Springfield, Columbia and Independence run municipal utilities.
Coal still supplies a large share of generation, alongside natural gas, the Callaway nuclear plant, growing wind and some hydro on the Osage River. The state straddles two regional grid operators, with Ameren in MISO and Evergy in the Southwest Power Pool. Hot, humid summers drive air-conditioning demand, while cold winters are heated mostly with natural gas. Net metering is available for rooftop solar.
