Most Oahu customers will see little change on their bills from Hawaiian Electric Co. this month, as November’s typical bill was 27 cents higher than October’s.

The bill for an Oahu household using 500 kilowatt-hours in November is $131.04, or 24.2 cents per kilowatt hour. In October, the bill was $130.77.

HECO spokesman Darren Pai said bills were relatively flat due to steady costs for fuel and power from independent power producers.

On Oahu, half of the energy HECO uses is bought from eight independent power producers. The independent power producers include AES Hawaii, a coal-fired facility in Kapolei, and the Kahuku Wind facility on the North Shore.

In the previous two months, electric bills fell. Still, the price of electricity in Hawaii is more than double the nation’s average.

Hawaii residents paid an average of 27.45 cents a kilowatt-hour in August; the national average was 12.91 cents in the same month, according to the latest figures from the U.S. Energy Information Administration.

Hawaii has the highest electricity rates in the nation, largely due to the state’s use of imported oil for most of its power. The state spent $5.4 billion on petroleum in 2016, according to the EIA.

Other states use a mix of energy resources such as natural gas, hydroelectric power, coal or nuclear power.

In 2015 oil made up roughly 71.1 percent of HECO’s energy mix on Oahu. HECO imports oil primarily from Southeast Asia and the Middle East.

The residential rate for HELCO customers on Hawaii island was 29.6 cents per kilowatt-hour. The average bill this month for a household using 500 kilowatt-hours on the Big Island is $159.72, down from $159.97.

Maui customers paid 25.2 cents per kilowatt-hour, down from 26.9 cents in October. The average bill for a household using 500 kilowatt-hours is $135.84, a drop from $143.94 last month.

Maui Electric Co. customers on Molokai using 400 kilowatt-hours of electricity are paying an average of $132.85 with a rate of 30.8 cents a kilowatt-hour, down from $128.21, with a rate of 29.6 cents a kilowatt-hour in October.

Lanai’s bills were consistent with the prior month, as residents using 400 kilowatt-hours of electricity on the island are paying 31.7 cents a kilowatt-hour. Lanai residents are paying $136.59 in November compared to $136.08 in October.

Bills on Lanai and Molokai are provided based on electrical use at 400 kilowatt-hours. This is due to lower energy use compared to Maui, Big Island and Oahu, HECO said.

HECO, MECO and HELCO monthly bills include the cost for kilowatt-hours used plus other charges. The Kauai Island Utility Cooperative increased its rate to 33.43 cents per kilowatt-hour in November, over a rate of 32.71 cents a kilowatt-hour in October. The typical bill for a household using 500 kilowatt-hours, including a $10.58 customer base charge, is $177.73, a $3 increase from $174.14.
