MidAmerican Energy rates and bills in Iowa

MidAmerican's price per kWh: 2025, last 12 months and the latest month

Three EIA figures answer "MidAmerican Energy rates per kWh", each for a different period:

• 2025, full year: 11.21¢ per kWh¹, from the annual EIA-861 survey of every utility.
• Last 12 months (September 2025 to August 2026): 11.58¢ per kWh, from EIA's monthly sample (2026 months preliminary).
• August 2026³ alone: 15.23¢ per kWh², preliminary.

All three are average revenue per kWh: what 639,558¹ residential customers paid in total, divided by what they used. The total includes the monthly basic service charge, energy charges, fuel and other cost-recovery charges, so the figure is not a price printed in MidAmerican's tariff, and households that use little pay more per kWh than the average while large users pay less. The August 2026³ figure is a single summer month and runs well above the 12-month average for reasons explained further down.

Fourth-lowest among the country's large utilities

Of the 177 US utilities with 100,000 or more residential customers that report a full-service price, MidAmerican ranked 4th lowest of 177 in 2025. The three below it were Magic Valley Electric Cooperative (Texas) at 10.51¢ per kWh, Clark Public Utilities (Washington) at 10.63¢ per kWh and Lincoln Electric System (Nebraska) at 11.15¢ per kWh; the median large utility averaged 15.07¢ per kWh. Against other investor-owned utilities the gap widens: MidAmerican's average was 37.0% below the national average for investor-owned utilities, which stood at 17.78¢ per kWh¹.

Half of Iowa's homes, and a wide gap with Alliant

MidAmerican's wires reach 51.0% of Iowa's residential customers, and Alliant Energy (IPL) serves another 33.4%. The two utilities sit at opposite ends of the state's price range: in 2025 MidAmerican was the lowest of the 9 Iowa utilities with 10,000 or more residential customers and Alliant the highest, at 17.77¢ per kWh, a spread of 6.56¢ per kWh. Iowa's cooperatives averaged 13.61¢ per kWh and its municipal and other public utilities 12.22¢ per kWh¹.

The difference carries through to bills even though MidAmerican homes use more electricity. A MidAmerican home used 828 kWh a month in 2025 and paid $92.85; an Alliant home used 739 kWh and paid $131.38¹. Over the last 12 months (September 2025 to August 2026) the averages were $94.51 and $136.45².

Nobody chooses between them. Iowa has no retail choice for homes, and EIA's territory records list MidAmerican in 55 counties, every one of them shared with at least one other utility; Alliant reports customers in 84⁴ counties. Whether a house is on MidAmerican's lines, Alliant's, a co-op's or a city utility's depends on the street, and the utilities' own service-area maps decide by address.

Cheaper kWh in winter than in summer

MidAmerican's monthly figures show a seasonal pattern in price, not only in use: the average price per kWh climbs through the summer and drops back in autumn. Use per home ranged from 553 kWh in November 2025 to 1,397 kWh in July 2026, while the average bill went from $55.80 to $193.59², a wider swing than use alone would produce. Summer kWh therefore carry a higher average price than winter kWh.

August 2026	15.23¢	781	$118.99

That is why the August 2026³ average, 15.23¢ per kWh, sits so far above the 12-month figure of 11.58¢ per kWh². A single month also moves with billing cycles and with how much was used: when use falls, the fixed monthly charge is spread over fewer kWh and the average per kWh rises. For a full-year bill estimate, the 12-month average is the better guide.

Rate increase: what the data show for 2025 and 2026

From 2024 to 2025, MidAmerican's residential average rose 1.8%, from 11.01¢ per kWh to 11.21¢ per kWh. The average bill grew faster, from $87.16 to $92.85 (+6.5%), because use per home also increased, from 791 kWh⁶ to 828 kWh¹ a month. Across all Iowa providers the residential average rose 1.6%⁷ over the same year.

In 2026 the monthly data point higher. The 12-month average (September 2025 to August 2026) of 11.58¢ per kWh is above the 2025 figure, and August 2026³ came in +15.6%² against the same month a year earlier. These months are preliminary and EIA revises them when the annual survey is final.

The rate case MidAmerican filed with the Iowa Utilities Commission in July 2026 asks to raise its natural gas rates, not its electric rates. Electric rate changes go before the same commission, whose filing system lists the open dockets. The guide to rate cases explains how such decisions reach a bill.

Iowa's power supply

EIA's generation data describe Iowa as a whole, not MidAmerican's own plants or purchases. In 2025, wind produced 58.5% of the state's electricity, the highest share of any state, against 31.5% in 2015; coal fell from 52.6% to 25.6% over the same years. Iowa generated 126%⁸ of what its customers bought in 2025.

Meters, time-of-use and rooftop solar

In EIA's 2025 meter data, 0.0% of MidAmerican's residential meters are listed as advanced (AMI) meters, against 99.4% at Alliant. Time-varying pricing is rare: 122 residential customers were enrolled in a time-of-use rate, 0.0%⁹ of the total. The time-of-use guide compares a flat rate with a time-based one on the same monthly use.

Rooftop solar is less common than at Alliant: 4,965 net-metered residential installations in 2025, 7.8 per 1,000 customers and 44.1 megawatts in total, against 29.5⁹ per 1,000 at Alliant.

Outages: major event days made the difference

MidAmerican customers averaged 205 minutes without power in 2025 counting all events, more than the Iowa average of 152 minutes. Excluding major event days, the days of unusually widespread outages that the IEEE 1366 standard sets apart, the figure was 82 minutes, close to the state's 78 minutes. On average each customer had 1.19¹⁰ interruptions. Alliant reports with another method (not IEEE 1366), so its outage minutes are not directly comparable.

Business customers and help with bills

Commercial customers paid MidAmerican 8.87¢ per kWh on average in 2025 and its 1,523 industrial accounts 6.47¢ per kWh, both below the residential 11.21¢ per kWh. Across all customer classes the average was 7.85¢ per kWh, against 13.03¢ per kWh¹ at Alliant.

Iowa received $58.8 million¹¹ in federal LIHEAP heating and cooling assistance for fiscal year 2026, which helps eligible households with energy bills. For prices across the state, see electricity in Iowa.
