Frequently Asked Questions

Which state has the cheapest electricity in 2026?+
North Dakota has the cheapest electricity in the US at 11.95 cents per kWh as of March 2026. The lowest-rate states benefit from abundant hydroelectric power, cheap natural gas, and low transmission costs. Idaho (13.01c), Nebraska (13.1c), Utah (13.17c), Iowa (13.42c) round out the five cheapest states.
Which state has the most expensive electricity?+
Hawaii has the most expensive electricity by far at 42.23 cents per kWh - roughly 2.3 times the national average. Hawaii's isolated island grids run on imported petroleum, adding $0.15-$0.25/kWh in fuel cost alone. California (33.35c), Connecticut (30.47c), Massachusetts (30.21c), Rhode Island (29.91c) follow as the most expensive states.
How much did electricity rates change by state year-over-year?+
US electricity rates rose an average of 8.6% year-over-year through March 2026, but state-level changes varied widely. District of Columbia (+22.5%), New Jersey (+18.2%), New Hampshire (+18.0%) saw the largest increases, driven by rate cases and fuel costs. Rhode Island (-7.4%), Connecticut (-6.2%), Oregon (-1.8%) saw the smallest changes.
Why do electricity rates vary so much between states?+
Five factors drive state-level variation: (1) Fuel mix - Hawaii burns imported oil while the Pacific Northwest uses cheap hydro; (2) Grid isolation - Hawaii's island grids are separate from the mainland; (3) Capacity prices - Northeast ISO-NE markets clear at high $/MW-day; (4) Regulatory environment - California's wildfire-mitigation rate-base is unique; (5) State taxes and public-benefit fees, which add 5-15% on top of the base rate.
