What it sells and charges
Full service (energy and delivery)
| Sector | Customers | Sales (MWh) | Revenue | Average price (cents per kWh) |
|---|---|---|---|---|
| Residential | 717,275 | 7,067,599 | $783,162,600 | 11.08 |
| Commercial | 119,202 | 5,742,898 | $500,209,400 | 8.71 |
| Industrial | 1,592 | 20,102,348 | $1,292,546,200 | 6.43 |
Delivery only
Delivery only, not your full price. Customers buy their energy from a retail provider and pay for it separately.
| Sector | Customers | Sales (MWh) | Revenue | Delivery revenue per kWh (cents) |
|---|---|---|---|---|
| Commercial | 59 | 12,244 | $250,100 | 2.04 |
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.
Catalyst Cooperative (PUDL), from FERC Form 714 · Annual peak demand by planning area (FERC Form 714, through PUDL) · data for 2006-2025 · as of Oct 14, 2026 · retrieved Oct 31, 2026 · CC-BY-4.0 May be out of date. The next release was due by Jan 14, 2027. Last checked for an update: Oct 31, 2026.
Reliability
| State | Standard | SAIDI with major events (minutes) | SAIFI with major events | SAIDI without major events (minutes) | SAIFI without major events |
|---|---|---|---|---|---|
| IA | IEEE 1366 | 205 | 1.19 | 82 | 0.75 |
| IL | IEEE 1366 | 304 | 1.87 | 143 | 1.47 |
| SD | IEEE 1366 | 399 | 0.93 | 65 | 0.42 |
SAIDI is the average minutes without power per customer in the year; SAIFI is how many outages the average customer had. Major event days are storms and similar rare days, counted with and without.
Generation it operates
| Fuel | Capacity | Net generation in 2025 |
|---|---|---|
| Wind | 7,771 MW | 25,982,502 MWh |
| Subbituminous coal | 3,740.2 MW | 14,043,568 MWh |
| Natural gas | 1,485.8 MW | 2,009,621 MWh |
| Solar | 142 MW | 286,199 MWh |
| Distillate fuel oil | 54 MW | 58,491 MWh |
| Hydro | 3.6 MW | 20,199 MWh |
| Batteries | 1.1 MW | -24 MWh |
| RC | 0 MWh |
This is generation the utility operates, not the full mix of power it buys. EIA does not publish that mix for each utility.
