Why this number
Wyoming runs heat pump longer than the national baseline in October–March — 8.8 hours a day on the NOAA state degree-day scaling used here, against 5.87 nationally — and pays 13.55¢/kWh for it. Those two numbers, times 3,500 W, are the whole $756.

What the numbers say about heat pump 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 heat pump 8.8 hours a day against the national 5.87 — 2.9 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 heat pump: $756 for the 182-day winter, against Nebraska’s $603 and Maine’s $2,061. PacifiCorp, Wyoming’s largest utility with 118,130 residential customers, averages 13.4¢ — $748 for the same hours — while Adjustment 2024 at 15.3¢ comes to $854, a $106 spread on identical use. Per million Btu delivered, this unit at the NEEP median COP of 2.17 costs $18.30 against $12.63 for natural gas at Wyoming’s winter average of $1.20/therm, which is the whole-house comparison the Wyoming heating page works through. 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 heat pump runs.
Frequently asked questions
How much does it cost to run heat pump per hour in Wyoming?
$0.47 an hour for a 3,500 W unit at Wyoming’s October 2025–March 2026 average average of 13.55¢/kWh (3,500 ÷ 1,000 × 0.1355); at PacifiCorp’s 13.4¢ it is $0.47.
How much does heat pump cost for the whole winter in Wyoming?
About $756: 3,500 W × 8.8 hours a day × 182 days (October–March) × 13.55¢. The hours are the national 5.87 h/day scaled by NOAA CPC state population-weighted HDD, October 2025–March 2026 (5,222 against the CONUS 3,500); enter your own hours above for your own figure.
Is heat pump expensive to run in Wyoming compared with other cold states?
Wyoming is the 17th most expensive of the 20 cold states on this site at $756 a winter; the range runs from Nebraska ($603) to Maine ($2,061), driven almost entirely by the electricity rate.
How we calculated this
Worked for heat pump in Wyoming: 3,500 W ÷ 1,000 × 0.1355 $/kWh = $0.47 per hour; hours per day = 5.87 × (5,222 ÷ 3,500) = 8.8; 3,500 ÷ 1,000 × 8.8 × 182 × 0.1355 = $756 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.
