Why this number
Wyoming runs space heater longer than the national baseline in October–March — 7.5 hours a day on the NOAA state degree-day scaling used here, against 5.0 nationally — and pays 13.55¢/kWh for it. Those two numbers, times 1,500 W, are the whole $276.

What the numbers say about space heater in Wyoming
Wyoming logged 5,222 population-weighted heating degree-days over October–March (NOAA CPC state series), 149% of the CONUS figure of 3,500, which is why this page runs space heater 7.5 hours a day against the national 5.0 — 2.5 hours more. At Wyoming’s October 2025–March 2026 average rate of 13.55¢/kWh that makes it the 17th most expensive of the 20 cold states for space heater: $276 for the 182-day winter, against Nebraska’s $220 and Maine’s $752. PacifiCorp, Wyoming’s largest utility with 118,130 residential customers, averages 13.4¢ — $273 for the same hours — while Adjustment 2024 at 15.3¢ comes to $312, a $39 spread on identical use. Per million Btu delivered, resistance heat at 13.55¢ costs $39.71 against $12.63 for natural gas at Wyoming’s winter average of $1.20/therm, so a 1,500 W heater is a room-by-room supplement in Wyoming, not a whole-house plan. Wyoming’s winter-average rate (13.55¢) sits 0.81¢ below its July 2026 reading of 14.36¢; the season figure uses the winter average because that is when space heater runs.

Wyoming is the 17th most expensive of the 20 cold states on this site at $276 a winter; the range runs from Nebraska ($220) to Maine ($752), driven almost entirely by the electricity rate.
How we calculated this
Worked for space heater in Wyoming: 1,500 W ÷ 1,000 × 0.1355 $/kWh = $0.20 per hour; hours per day = 5.0 × (5,222 ÷ 3,500) = 7.5; 1,500 ÷ 1,000 × 7.5 × 182 × 0.1355 = $276 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.
