Rock Energy Cooperative electricity rates

It is a smaller system, serving 7,310 residential customers, which means its fixed costs are spread across a narrow base. At 14.47¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Wisconsin, 26.7% under the statewide average of 19.74¢.

Consumption is close to the national norm at 954 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.

Owned by the customers it serves, with directors elected by members. Co-ops are frequently outside state rate regulation. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

In 2024 the average Rock Energy Cooperative customer went 88 minutes without electricity across 0.55 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

66 residential customers had net-metered solar in 2024, totalling 0.53 megawatts. That works out to 9 installations per thousand customers, against a median of 8 across the utilities reporting it.

Adoption is above the national median, which generally tracks the retail rate more closely than it tracks sunshine. What exports are actually worth.
