Hawaii Electricity Rate: What You Need to Know
Hawaii electricity averages 52.72 cents per kWh for residential customers as of June 2026, according to the EIA Electric Power Monthly. This is 34.38c above the US average of 18.34c/kWh. The average monthly bill for Hawaii households is $207 based on typical usage of 509 kWh.
Hawaii's 52.72c/kWh rate (June 2026) is the highest in the US by a wide margin - 2.9 times the national average. Every Hawaiian island operates as a completely isolated grid with no interconnection to any other island or to the mainland. HECO (Hawaiian Electric) subsidiaries on each island (Hawaiian Electric on Oahu, Maui Electric on Maui, Lanai Customer Service on Lanai) generate most of their electricity from imported petroleum - oil tankers making a 2,500-mile Pacific crossing add $0.15-$0.25/kWh in logistics costs to every kilowatt generated. Hawaii's 2026 rate case approved additional cost recovery for grid modernization, including the transition to renewable generation (HECO targets 100% renewable by 2045). Solar is the most cost-effective energy move for Hawaii homeowners: at 52.72c/kWh, a $25,000 solar system pays back in 6 years even without the federal ITC (which expired December 2025).
Generation mix: Petroleum 80%, solar 15%, wind 5%. The fuel mix is a primary driver of electricity rates - states with abundant hydro or nuclear tend to have lower rates, while states dependent on imported petroleum (Hawaii) or natural gas pay more.
Year-over-year change: Hawaii rates rose 28.7% year-over-year as of June 2026. This compares to the US average increase of 5% over the same period.
