Why this number
Wyoming runs ductless mini-split longer than the national baseline in October–March — 14.0 hours a day on the NOAA state degree-day scaling used here, against 9.4 nationally — and pays 13.55¢/kWh for it. Those two numbers, times 2,000 W, are the whole $692.

What the numbers say about ductless mini-split 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 ductless mini-split 14.0 hours a day against the national 9.4 — 4.6 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 ductless mini-split: $692 for the 182-day winter, against Nebraska’s $552 and Maine’s $1,886. PacifiCorp, Wyoming’s largest utility with 118,130 residential customers, averages 13.4¢ — $684 for the same hours — while Adjustment 2024 at 15.3¢ comes to $781, a $97 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 ductless mini-split runs.

How we calculated this
Worked for ductless mini-split in Wyoming: 2,000 W ÷ 1,000 × 0.1355 $/kWh = $0.27 per hour; hours per day = 9.4 × (5,222 ÷ 3,500) = 14.0; 2,000 ÷ 1,000 × 14.0 × 182 × 0.1355 = $692 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.
