There are several simple ways to take advantage of this new rate design, which Hawaiian Electric is communicating to customers selected for enrollment. Customers may pursue energy efficiency measures (e.g., install efficient appliances and lightbulbs), shift energy usage away from the evening peak period (e.g., set timers for water heaters, laundry, and other appliances), schedule ...

No, the highest period, the evening peak period, will be about 50% higher than current rates. The 1:2:3 ratio means that the evening peak rate will be 3 times the rate in the lowest period, the daytime period. The daytime period rate will be about half the current rate.

TOU rates are set at a 1:2:3 ratio for the daytime, overnight, and evening peak energy rates, respectively. Compared to existing energy rates, customers can expect overnight energy rates (9pm-9am) to be approximately the same as current rates, daytime energy rates (9am-5pm) to be approximately half of current rates, and evening peak energy rates (5pm-9pm) ...

Time of Use (“TOU”) rates charge customers different rates for electricity based on when they use it. This better aligns electricity prices with the cost to produce it. For example, energy is cheapest during the day when there is abundant solar, and most expensive in the evening when demand is high and fossil fuels replace ...
