Montana-Dakota Utilities Co electricity rates

It is a smaller system, serving 14,706 residential customers, which means its fixed costs are spread across a narrow base. At 11.77¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Wyoming, 20.5% under the statewide average of 14.80¢.

Consumption is close to the national norm at 849 kilowatt-hours a month against 871, so the rate translates fairly directly into the bill.

A shareholder-owned company whose rates are set by the state regulator, including an approved return on the capital it has invested. 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 Montana-Dakota Utilities Co customer went 107 minutes without electricity across 0.67 interruptions. The median across the 941 utilities that report this is 185 minutes.

That is better than the typical American utility, though the figure includes major storm days and can move sharply from one year to the next.

169 residential customers had net-metered solar in 2024, totalling 1.22 megawatts. That works out to 11.5 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.
