Why Iowa pays what it pays

Iowa generates more of its electricity from wind than any other state, more than half of in-state generation in recent years. Wind has effectively zero fuel cost, and Iowa's utilities own much of their fleet outright rather than buying it under contract, so the low marginal cost flows to ratepayers rather than to a merchant generator.

The state also has favourable structural conditions: flat terrain that makes distribution cheap to build and maintain, a large industrial and agricultural load that spreads fixed costs, and a regulatory framework that has supported utility-owned renewables through rate base rather than competitive procurement.

Iowa's rate was essentially flat year over year, one of only a handful of states that did not rise. That is what a mostly fuel-free generation fleet looks like when gas prices move.

Where Iowa power comes from

Iowa generated 74 TWh in 2025, the 21th largest output of any state. Wind supplied 58.9% of it, enough that the price of that fuel largely sets the price of electricity here. Renewables accounted for 62.2%, against 23.8% nationally, which ranks Iowa #6 of 51.

  • Wind 44 TWh
  • Coal 19 TWh
  • Natural gas 9 TWh
  • Solar 1 TWh
  • Hydroelectric 1 TWh

What Iowa households actually pay

Average monthly bill $119 -23.5% vs the U.S. average of $155
Average monthly usage 850 kWh · U.S. average 871
Bill rank #43 of 51 · rate rank #43
Bill year over year +5.3% from $113 the year before

Iowa looks more expensive on paper than it is in practice. Its rate ranks #43 of 51, but the average bill ranks only 43rd, because households there use 850 kWh a month against a national average of 871. See how every state compares on bills.

Heating in Iowa: gas, heat pump or resistance

Residential natural gas in Iowa averaged $10.33 per thousand cubic feet in 2024, about $1.00 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.

Gas furnace $11.07 at 90% efficiency
Heat pump $13.81 at a seasonal COP of 3
Electric resistance $41.44 baseboard, wall or electric furnace

In Iowa, gas remains cheaper to run than a heat pump by about $2.74 per million BTU at these assumptions, roughly $164 over a 60 million BTU season. A heat pump can still be the better purchase once cooling, equipment age and incentives are counted, but not on heating cost alone.

What each Iowa utility charges

The statewide average hides a wide spread. Across the 20 Iowa utilities reporting to the EIA, rates run from 9.26¢ at North West Rural Electric Coop to 17.90¢ at Interstate Power and Light Co . Together they serve 1.2 million residential customers.

Who sells electricity in Iowa

MidAmerican Energy, a Berkshire Hathaway Energy company, serves much of the state and owns a very large wind fleet. Alliant Energy's Interstate Power and Light covers most of the rest. Municipal utilities and rural electric co-operatives are widespread.

Iowa has no residential retail choice. Utilities are vertically integrated within MISO.

Iowa sits in The Midwest. A single wholesale market stretching from Manitoba to the Gulf, containing both the cheapest wind states and some of the highest delivery costs in the country. Read the regional analysis.

What you can actually do about it

Iowa's low rate makes electrification arithmetic unusually favourable. Heat pumps and electric vehicles pay back faster here than in most states, because the operating cost comparison against gas and petrol starts from a lower base.

Data-centre load growth in central Iowa is the thing to watch. It has so far come with its own generation contracts rather than being socialised across residential customers, but it is the main variable in the state's medium-term rate path.

Closest states by price

These jurisdictions charge within a fraction of a cent of Iowa, which is useful if you are comparing a move or a multi-state operating cost.

Iowa electricity rates: common questions

What is the average electricity rate in Iowa?

The average residential electricity rate in Iowa is 14.14 cents per kilowatt-hour as of May 2026, according to the U.S. Energy Information Administration. That is -23.3% relative to the national average of 18.44¢/kWh.

How much is the average monthly electric bill in Iowa?

The average Iowa household paid $119 a month across the twelve months to May 2026, using an average of 850 kWh. That is -23.5% against the U.S. average bill of $155, and it ranks 43rd highest of the 51 jurisdictions. Your own bill depends on the size of your home, your heating and cooling equipment and your rate schedule.

Why is the Iowa bill ranking different from its rate ranking?

A bill is the rate multiplied by usage, and usage varies between states more than price does. Iowa ranks #43 of 51 on price but 43rd on the actual bill, because households there use about 850 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.

Have electricity rates in Iowa gone up?

Iowa rates fell 0.1% over the year to May 2026, from 14.16¢ in May 2025 to 14.14¢.

Can I choose my electricity supplier in Iowa?

Regulated monopoly. Iowa households buy both supply and delivery from their local regulated utility or co-operative; there is no competitive residential supplier market.
