Where High Plains Power Inc sits

It is a smaller system, serving 12,767 residential customers, which means its fixed costs are spread across a narrow base. Its 13.71¢ per kilowatt-hour sits 7.4% below the Wyoming average of 14.80¢.

Consumption is close to the national norm at 951 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.
