Why this number
Wyoming runs central air conditioner less than the national baseline in June–August — 1.3 hours a day on the NOAA state degree-day scaling used here, against 3.8 nationally — and pays 14.36¢/kWh for it. Those two numbers, times 3,500 W, are the whole $61.

What the numbers say about central air conditioner in Wyoming
Wyoming logged 332 population-weighted cooling degree-days over June–August (NOAA CPC state series), 35% of the CONUS figure of 958, which is why this page runs central air conditioner 1.3 hours a day against the national 3.8 — 2.5 hours less. At Wyoming’s July 2026 rate of 14.36¢/kWh that makes it the 19th most expensive of the 20 cold states for central air conditioner: $61 for the 92-day summer, against Montana’s $47 and Alaska’s $228. PacifiCorp, Wyoming’s largest utility with 118,130 residential customers, averages 13.4¢ — $57 for the same hours — while Adjustment 2024 at 15.3¢ comes to $65, a $8 spread on identical use. Wyoming’s July 2026 rate of 14.36¢ sets the $0.50 per hour; its winter average of 13.55¢ is 0.81¢ lower, a difference that matters for heating loads but not for central air conditioner use in June–August.

How we calculated this
Worked for central air conditioner in Wyoming: 3,500 W ÷ 1,000 × 0.1436 $/kWh = $0.50 per hour; hours per day = 3.8 × (332 ÷ 958) = 1.3; 3,500 ÷ 1,000 × 1.3 × 92 × 0.1436 = $61 for the summer.
