What the EIA series shows for Hawaii

Past 12 months (June 2025 → June 2026)
The Hawaii residential rate rose 28.7% (+11.76¢/kWh), from 40.96¢ in June 2025 to 52.72¢ in June 2026.
Past 5 years (June 2021 → June 2026)
The rate rose 59.9% (+19.75¢/kWh), from 32.97¢ in June 2021 to 52.72¢ in June 2026.
Past 10 years (June 2016 → June 2026)
The rate rose 91.7% (+25.22¢/kWh), from 27.50¢ in June 2016 to 52.72¢ in June 2026.
Highest and lowest month on record
In this series the Hawaii rate peaked at 52.72¢/kWh in June 2026 and bottomed at 14.73¢/kWh in March 2002. The series covers January 2001 to June 2026.
Steepest 12-month increase
The largest single-year move in the series ended in September 2008: the rate rose 57.2% (+13.44¢/kWh), from 23.50¢ in September 2007 to 36.94¢ in September 2008. That is when the change happened; the series does not say what caused it.
Against the rest of the country
Over the same window the unweighted average across the 51 jurisdictions with data for this period rose 34.8%, so Hawaii's +59.9% outpaced the nationwide move by 25.1 percentage points. That gap is the part of the movement this dataset cannot attribute to a nationwide trend — it does not identify what else was involved.
Rank among jurisdictions (June 2021 → June 2026)
Measured over that identical five-year window, Hawaii's change is the 4th largest of the 51 jurisdictions whose series covers it — rank 1 is the biggest increase, rank 51 the biggest decrease. The rank places the movement; it does not explain it.

Between January 2001 and June 2026 the rate peaked at 52.72¢/kWh in June 2026 and bottomed at 14.73¢/kWh in March 2002.

What generally moves electricity rates

A rate series shows what changed, not why. This dataset records Hawaii's residential rate and nothing about what moved it, and no reviewed Hawaii driver analysis is published yet — so this page makes no causal claim. The factors that generally move retail rates are documented separately.

  • Fuel and purchased power. Natural gas, coal, and wholesale power prices pass through to retail rates, often with a lag of months.
  • Generation mix. Hydro and legacy nuclear tend to hold rates down; imported fuel, oil, and constrained supply tend to push them up.
  • Wires investment. Transmission and distribution upgrades, storm hardening, and wildfire mitigation are recovered through rates over years.
  • Market structure. Regulated utilities set rates in rate cases; deregulated markets price supply competitively and bill delivery separately.
  • Demand and weather. Load growth, peak-heavy demand, and extreme weather raise the cost of serving each kilowatt-hour.

the factors themselves are documented on electricity generation cost drivers.
