Just like the price of fuel, the cost to run Hawaiian Electric Company's electric plants have also increased.
That means that extra cost is passed down to customers.
But as oil prices have started to come down, your electric bill should also start going down as well.
"First off, we do maintain a one-month inventory fuel on the island, so that makes the impact of any increase or decrease a little bit more gradual over time," said Hawaiian Electric Spokesperson Darren Pai.
If oil price continues to fall, your electric bill will mirror that trend.
