What the numbers say about space heater in North Dakota
North Dakota logged 6,960 population-weighted heating degree-days over October–March (NOAA CPC state series), 199% of the CONUS figure of 3,500, which is why this page runs space heater 9.9 hours a day against the national 5.0 — 4.9 hours more. At North Dakota’s October 2025–March 2026 average rate of 11.71¢/kWh that makes it the 12th most expensive of the 20 cold states for space heater: $318 for the 182-day winter, against Nebraska’s $220 and Maine’s $752. Northern States Power Co - Minnesota, North Dakota’s largest utility with 82,987 residential customers, averages 12.1¢ — $328 for the same hours — while Cass County Elec Coop Inc at 12.4¢ comes to $337, a $8 spread on identical use. Per million Btu delivered, resistance heat at 11.71¢ costs $34.32 against $10.11 for natural gas at North Dakota’s winter average of $0.96/therm, so a 1,500 W heater is a room-by-room supplement in North Dakota, not a whole-house plan. North Dakota’s winter-average rate (11.71¢) sits 1.70¢ below its July 2026 reading of 13.41¢; the season figure uses the winter average because that is when space heater runs.

How we calculated this
Worked for space heater in North Dakota: 1,500 W ÷ 1,000 × 0.1171 $/kWh = $0.18 per hour; hours per day = 5.0 × (6,960 ÷ 3,500) = 9.9; 1,500 ÷ 1,000 × 9.9 × 182 × 0.1171 = $318 for the winter. Rate: EIA Electric Power Monthly 5.6.A (October 2025–March 2026 average); degree-days: NOAA CPC state population-weighted HDD, October 2025–March 2026, against the CONUS total; utility prices: EIA-861 2024.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
