Its average price is 19% below the state average for residential customers (13.62 cents per kWh in IA).

How we got this

$783,162,600 residential revenue ÷ 7,067,599,000 kWh residential sales = 11.08 cents per kWh

Average price is revenue divided by sales, for full-service customers only. It averages every rate and every month, so one household's price can differ. State averages count revenue from every kind of service and sales only once, as EIA does.

Annual peak demand

Not reported to FERC. Only utilities that plan or balance their own system file Form 714.

Its balancing authority, MISO, peaked at 121,059 MW in 2025. That is the balancing authority's peak, not this utility's.
