How MDU’s plans work
Rate 10 (Residential Electric Service). In July every kWh costs about 11.6¢, whatever the month's use. Fixed charge: $19.23 a month.
Rate 16 (Optional Time-of-Day Residential Service). Peak noon–8 pm on July weekdays; 8 of 24 hours carry the top price of 13.5¢. The cheapest July weekday hour costs 9.7¢, so moving 1 kWh out of the top hours saves 3.8¢. January weekdays range from 7.8¢ to 11.6¢. Summer pricing applies Jun–Sep; winter pricing Oct–May. Weekends differ: off-peak all day. Fixed charge: $30.36 a month.
Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.
As a cross-check, MDU billed its residential customers an average of 11.06¢ per kWh in 2025 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for North Dakota’s price change since.
