Save Money with Hawaii Energy’s Rebates.
Hawaii Energy’s cash rebates help you invest in energy-efficient equipment for your home. These installations quickly pay for themselves and the savings keep coming year after year.

Rebates are available to residential electric utility ratepayers on Hawaii Island, Lanai, Maui, Molokai and Oahu only. They are available on a first-come, first-served basis and are subject to availability of funds, restrictions, change and/or discontinuation without advance notice. Kauai residents are serviced by a utility cooperative and therefore not eligible for Hawaii Energy rebates. Please contact the Kauai Island Utility Cooperative for more information at (808) 246-4300.

Smart Devices Click here to request rebate info

Measuring and monitoring energy use can have an impressive impact. In fact, just the idea that their energy use will be individually measured (and billed!) is enough to motivate people to reduce their energy use before the meters are even installed! Multifamily and commercial buildings with electrical “master-meters” can minimize operating costs and reduce energy consumption by submetering common areas, owners’ units and mixed-use vendors, as well as parking structures and retail spaces.

Water Heating
Energy-efficient alternatives to water heating, such as the installation of heat pump water heaters or solar water heating, is a great way to give your water heater a break.
