Why this number
Alaska runs dehumidifier less than the national baseline in June–August — 7.8 hours a day on the EIA division degree-day scaling used here, against 12.0 nationally — and pays 28.83¢/kWh for it. Those two numbers, times 500 W, are the whole $103.

What the numbers say about dehumidifier in Alaska
NOAA publishes no state series for Alaska, so this page uses the EIA STEO Pacific census division cooling degree-days, June–August 2026: 667, 65% of the US 1,032, which is why this page runs dehumidifier 7.8 hours a day against the national 12.0 — 4.2 hours less. At Alaska’s July 2026 rate of 28.83¢/kWh that makes it the most expensive of the 20 cold states for dehumidifier: $103 for the 92-day summer, against Montana’s $21 and Alaska’s $103. Chugach Electric Assn Inc, Alaska’s largest utility with 97,048 residential customers, averages 21.2¢ — $76 for the same hours — while Golden Valley Elec Assn Inc at 30.3¢ comes to $108, a $32 spread on identical use. Alaska’s July 2026 rate of 28.83¢ sets the $0.14 per hour; its winter average of 26.11¢ is 2.72¢ lower, a difference that matters for heating loads but not for dehumidifier use in June–August.
Frequently asked questions
How much does it cost to run dehumidifier per hour in Alaska?
$0.14 an hour for a 500 W unit at Alaska’s July 2026 average of 28.83¢/kWh (500 ÷ 1,000 × 0.2883); at Chugach Electric Assn Inc’s 21.2¢ it is $0.11.
How much does dehumidifier cost for the whole summer in Alaska?
About $103: 500 W × 7.8 hours a day × 92 days (June–August) × 28.83¢. The hours are the national 12.0 h/day scaled by EIA STEO Pacific census division cooling degree-days, June–August 2026 (667 against the US 1,032); enter your own hours above for your own figure.
Is dehumidifier expensive to run in Alaska compared with other cold states?
Alaska is the most expensive of the 20 cold states on this site at $103 a summer; the range runs from Montana ($21) to Alaska ($103), driven almost entirely by the electricity rate.
How we calculated this
Worked for dehumidifier in Alaska: 500 W ÷ 1,000 × 0.2883 $/kWh = $0.14 per hour; hours per day = 12.0 × (667 ÷ 1,032) = 7.8; 500 ÷ 1,000 × 7.8 × 92 × 0.2883 = $103 for the summer. Rate: EIA Electric Power Monthly 5.6.A (July 2026); degree-days: EIA STEO Pacific census division cooling degree-days, June–August 2026, against the US total; utility prices: EIA-861 2024.Sources: U.S. Energy Information Administration (EIA) electricity rates · DSIRE incentive records · public IRS/OBBBA guidance.
