Why this number
Nebraska runs window air conditioner less than the national baseline in June–August — 3.2 hours a day on the NOAA state degree-day scaling used here, against 3.6 nationally — and pays 13.78¢/kWh for it. Those two numbers, times 1,100 W, are the whole $45.

What the numbers say about window air conditioner in Nebraska
Nebraska logged 853 population-weighted cooling degree-days over June–August (NOAA CPC state series), 89% of the CONUS figure of 958, which is why this page runs window air conditioner 3.2 hours a day against the national 3.6 — 0.4 hours less. At Nebraska’s July 2026 rate of 13.78¢/kWh that makes it the 8th most expensive of the 20 cold states for window air conditioner: $45 for the 92-day summer, against Montana’s $14 and Alaska’s $68. Omaha Public Power District, Nebraska’s largest utility with 362,918 residential customers, averages 12.4¢ — $40 for the same hours — while Lincoln Electric System at 10.9¢ comes to $35, a $5 spread on identical use. Nebraska’s July 2026 rate of 13.78¢ sets the $0.15 per hour; its winter average of 12.31¢ is 1.47¢ lower, a difference that matters for heating loads but not for window air conditioner use in June–August.

How we calculated this
Worked for window air conditioner in Nebraska: 1,100 W ÷ 1,000 × 0.1378 $/kWh = $0.15 per hour; hours per day = 3.6 × (853 ÷ 958) = 3.2; 1,100 ÷ 1,000 × 3.2 × 92 × 0.1378 = $45 for the summer.
