Where City of Gillette sits
It is a smaller system, serving 13,990 residential customers, which means its fixed costs are spread across a narrow base. At 12.62¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Wyoming, 14.7% under the statewide average of 14.80¢.
Consumption is close to the national norm at 885 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.
Owned by the city it serves and governed by a local board rather than the state commission. No shareholder return is built into the rate. 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.

Rooftop solar on this system
24 residential customers had net-metered solar in 2024, totalling 0.32 megawatts. That works out to 1.7 installations per thousand customers, against a median of 8 across the utilities reporting it.
Adoption is below the national median. A low retail rate reduces what solar displaces, and export compensation set at avoided cost rather than the retail rate reduces it further. What exports are actually worth.
