Public Utilities Commission

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 solar energy. TOU rates provide an incentive for customers to shift energy consumption to the lower-cost daytime period, which may reduce customer costs and emissions. Hawaiian Electric’s Shift and Save program is a one-year TOU Study in which a subset of customers will be enrolled in TOU rates, launching on February 1, 2024. Customers may choose not to participate. See the Commission’s Advanced Rate Design page and Hawaiian Electric’s website for more information.
