About electricity rates in Iowa
Iowa has a regulated market without retail choice. MidAmerican Energy, which serves Des Moines and much of the state, and Alliant Energy's Interstate Power and Light are the two investor-owned utilities, overseen by the state's utilities regulator. Iowa also has an unusually large number of municipal utilities and rural electric cooperatives, which together serve a significant share of customers.
Wind now supplies most of the electricity generated in the state, one of the largest wind shares in the country, with coal and natural gas providing much of the rest. Cold winters are mostly heated with natural gas or propane, hot and humid summers create air-conditioning peaks, and farming adds grain drying and livestock loads. Net metering is offered by the larger utilities, and rooftop solar has grown steadily in recent years.
