Why this number
Colorado runs dehumidifier less than the national baseline in June–August — 6.6 hours a day on the NOAA state degree-day scaling used here, against 12.0 nationally — and pays 17.0¢/kWh for it. Those two numbers, times 500 W, are the whole $52.

What the numbers say about dehumidifier in Colorado
Colorado logged 527 population-weighted cooling degree-days over June–August (NOAA CPC state series), 55% of the CONUS figure of 958, which is why this page runs dehumidifier 6.6 hours a day against the national 12.0 — 5.4 hours less. At Colorado’s July 2026 rate of 17.0¢/kWh that makes it the 11th most expensive of the 20 cold states for dehumidifier: $52 for the 92-day summer, against Montana’s $21 and Alaska’s $103. Public Service Co of Colorado, Colorado’s largest utility with 1,365,053 residential customers, averages 15.0¢ — $46 for the same hours — while CORE Electric Cooperative at 15.0¢ comes to $46, a $0 spread on identical use. Colorado’s July 2026 rate of 17.0¢ sets the $0.09 per hour; its winter average of 16.45¢ is 0.55¢ lower, a difference that matters for heating loads but not for dehumidifier use in June–August.

How we calculated this
Worked for dehumidifier in Colorado: 500 W ÷ 1,000 × 0.1700 $/kWh = $0.09 per hour; hours per day = 12.0 × (527 ÷ 958) = 6.6; 500 ÷ 1,000 × 6.6 × 92 × 0.1700 = $52 for the summer.
