Average Price of Electricity

How much does your electricity cost?

Electricity prices in Hawaii are generally higher than on the U.S. mainland due to the cost of imported oil used to power many of the islands’ generators. The fluctuation in the cost of fuel, which makes up roughly 50 percent of a typical bill, is the biggest driver.

Our isolated geographic location also contributes to the higher cost of electricity because we don’t have any nearby utility companies from which to draw power in the event of a problem. So for system reliability, we must have reserve generating capacity and multiple distribution routes.

Electricity prices in 2021 for Oahu, Hawaii Island, Maui, Molokai, and Lanai increased compared to 2020.

Electricity rates vary by type of customer because they’re based on the cost of providing service. The charts below show the average price paid per kilowatt-hour (kWh) in 2021 by each type of customer (rate schedule) for each of our divisions.
