Montana-Dakota Utilities Co
Montana-Dakota Utilities Co is investor owned serving 19,616 residential customers in Montana, at an average residential price of 12.89¢ per kilowatt-hour.
That price is derived, and it is annual. It is total residential revenue divided by total residential sales in EIA’s 2024 survey — not a tariff, and not this month’s rate. For what a kilowatt-hour costs in Montana right now, see the state page, currently 15.14¢.
