Residential electricity rates rose in April on all islands except for Hawaii island.
Hawaiian Electric Co. said a typical 600-kilowatt-hour bill for Oahu residential customers rose by 51 cents to $204.25 in April. The effective rate for electricity in Honolulu is 32.6 cents a kilowatt-hour in month, little changed from March.
Elsewhere in the state:
>> Maui Electric Co. customers saw rates rise to 36.5 cents per kilowatt-hour this month from March’s 36.3 cents. The typical Maui bill rose by $1.30 to $226.76.
>> Hawaii island residential rates fell to 40.4 cents a kilowatt-hour from last month’s 41.30 cents. The typical bill fell by $6.28 to $252.91 The decline was largely due to a ruling by the state Public Utilities Commission that slightly reduced the amount Hawaii Electric Light Co. was allowed to collect in its latest rate case.
>> On Kauai, the rate rose to 45.8 cents per kilowatt-hour. Last month the rate charged by the Kauai Island Utility Cooperative was 42.6 cents a kilowatt-hour.
Hawaii typically has the highest cost for electricity in the nation. The national average was 11.43 cents a kilowatt-hour in January, the most recent numbers available from the U.S. Energy Information Administration.
