How to read Iowa

Iowa's 2025 EIA residential average was 13.62 cents per kWh, lower than Illinois, Michigan, or Ohio. The sun figure we use statewide is about 4.3 peak sun hours. A lower rate means each avoided kilowatt-hour is worth less, so the price per watt has to be sharp. MidAmerican Energy and Alliant Energy split most of the state.

Utilities

MidAmerican Energy serves Des Moines, Council Bluffs, and much of western and central Iowa, including parts of the Quad Cities. Alliant Energy, as Interstate Power and Light, serves Cedar Rapids, Iowa City, and much of eastern and northern Iowa. Municipal utilities serve Ames and some other cities. Illinois ComEd and Ameren rules stop at the river.

Export credits and tariffs

Iowa has net metering tariffs at its investor-owned utilities, with caps, annual cash-out, or credit rules that differ by company and rate. MidAmerican and Alliant publish their own riders. Some municipal utilities do too. We do not quote a statewide credit. Iowa does not have an Illinois Shines-style incentive, and an Illinois disclosure form does not apply on the Iowa side of the Quad Cities.

Climate and roofs

Winters are cold and snowy. Summer production carries the year. Hail and straight-line wind show up often enough that roof age belongs in the first meeting. A steep south roof sheds snow. A low-tilt roof holds it.
