Why this number

Running central air conditioner in Nebraska costs about $0.48 an hour and roughly $150 for the summer — a 3,500 W unit for 3.4 hours a day over 92 days (June–August) at Nebraska’s July 2026 average of 13.78¢/kWh. The hours are the national 3.8 h/day baseline scaled by NOAA CPC state population-weighted CDD, June–August 2026 (853 vs the CONUS 958); your utility’s rate moves it (table below), and the calculator takes your own wattage, hours and rate.

Nebraska runs central air conditioner less than the national baseline in June–August — 3.4 hours a day on the NOAA state degree-day scaling used here, against 3.8 nationally — and pays 13.78¢/kWh for it. Those two numbers, times 3,500 W, are the whole $150.

What the numbers say about central 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 central air conditioner 3.4 hours a day against the national 3.8 — 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 central air conditioner: $150 for the 92-day summer, against Montana’s $47 and Alaska’s $228. Omaha Public Power District, Nebraska’s largest utility with 362,918 residential customers, averages 12.4¢ — $135 for the same hours — while Lincoln Electric System at 10.9¢ comes to $119, a $16 spread on identical use. Nebraska’s July 2026 rate of 13.78¢ sets the $0.48 per hour; its winter average of 12.31¢ is 1.47¢ 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 Nebraska: 3,500 W ÷ 1,000 × 0.1378 $/kWh = $0.48 per hour; hours per day = 3.8 × (853 ÷ 958) = 3.4; 3,500 ÷ 1,000 × 3.4 × 92 × 0.1378 = $150 for the summer. Rate: EIA Electric Power Monthly 5.6.A (July 2026); degree-days: NOAA CPC state population-weighted CDD, June–August 2026, against the CONUS total; utility prices: EIA-861 2024.
