What the numbers say about heat pump in Wisconsin
Wisconsin logged 6,152 population-weighted heating degree-days over October–March (NOAA CPC state series), 176% of the CONUS figure of 3,500, which is why this page runs heat pump 10.3 hours a day against the national 5.87 — 4.4 hours more. At Wisconsin’s October 2025–March 2026 average rate of 18.39¢/kWh that makes it the 8th most expensive of the 20 cold states for heat pump: $1,209 for the 182-day winter, against Nebraska’s $603 and Maine’s $2,061. Wisconsin Electric Power Co, Wisconsin’s largest utility with 1,048,148 residential customers, averages 19.2¢ — $1,262 for the same hours — while Wisconsin Public Service Corp at 16.2¢ comes to $1,065, a $197 spread on identical use. Per million Btu delivered, this unit at the NEEP median COP of 2.17 costs $24.84 against $11.47 for natural gas at Wisconsin’s winter average of $1.09/therm, which is the whole-house comparison the Wisconsin heating page works through. Wisconsin’s winter-average rate (18.39¢) sits 0.67¢ below its July 2026 reading of 19.06¢; the season figure uses the winter average because that is when heat pump runs.

How we calculated this
Worked for heat pump in Wisconsin: 3,500 W ÷ 1,000 × 0.1839 $/kWh = $0.64 per hour; hours per day = 5.87 × (6,152 ÷ 3,500) = 10.3; 3,500 ÷ 1,000 × 10.3 × 182 × 0.1839 = $1,209 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.
