What is the current HECO rate per kWh?+
HECO (Hawaiian Electric)'s estimated effective residential rate is about 42.97 cents per kWh as of March 2026. This is a representative average; your exact rate depends on the tariff, season, and fuel/rider charges shown on the utility's official rate schedule (linked below). The estimated commercial rate is 38.12c/kWh, and the monthly fixed customer charge is roughly $18 regardless of usage.
What rate structure does HECO use?+
HECO (Hawaiian Electric) uses a tiered rate structure. Tiered rates charge a higher rate once your usage exceeds a baseline allowance (typically set at 50-100% of average usage for your climate zone).
How do I find my HECO rate on my bill?+
Your electricity bill shows the total kWh consumed and the charges applied. Look for the 'energy charge' or 'supply charge' line item - this is the per-kWh rate times your usage. Delivery charges (transmission and distribution) are listed separately and represent a significant portion of your total rate. The fixed customer charge appears as a flat line item. Your effective combined rate (all charges / total kWh) may differ from the tariff rate due to the fixed charge amortization.
