Hawaiʻi Energy announces rebates to help residents, businesses lower energy costs

Hawaiʻi Energy — the state’s energy conservation program — launched its 2026-27 rebate program as Hawaiʻi residents and businesses continue to look for ways to manage everyday expenses.

The program is available through June 30, 2027, and aimed at helping residents and businesses throughout the state lower their electricity bills with energy efficient upgrades.

Hawaiʻi Energy’s rebates offset the cost of purchasing and installing a wide range of energy efficient appliances and equipment. Rebates are available on a first come, first served basis while funding lasts.

“For many Hawaiʻi residents, reducing energy use is one of the most effective ways to lower monthly expenses,” said Hawaiʻi Energy Executive Director Caroline Carl in a release about the rebate program. “Whether it’s replacing an aging water heater or upgrading cooling equipment, our rebates help make those investments more affordable so families and businesses can begin saving sooner and continue benefiting from lower electricity bills for years to come.”

Cooling can account for as much as half of a home’s electricity use during the summer, making energy efficient upgrades especially valuable.

Electric water heating is also one of the largest contributors to household energy consumption, with efficient water heating systems capable of reducing a home’s electric bill by up to 40%.

Hawaiʻi Energy’s 2026-27 rebate offerings include incentives for a variety of residential and commercial energy saving improvements.
