Available now through June 30, 2026, Hawai‘i Energy’s rebates cover a wide range of improvements, from solar water heaters, ENERGY STAR® appliances, and cooling systems for homes to compressed air systems, cool roofs, and custom energy-saving projects for businesses. All rebates are offered on a first-come, first-served basis and will remain available while funding lasts.
“Energy efficiency upgrades offer some of the fastest and most affordable relief for households facing high utility costs,” said Caroline Carl, executive director of Hawai‘i Energy.
“With uncertainty surrounding federal energy programs and the potential rollback of tools like ENERGY STAR, these rebates come at a pivotal time to lock in long-term savings. By taking action now, residents and businesses can benefit themselves and also contribute to Hawai‘i’s progress toward a cleaner, more resilient energy future.”
Hawaiʻi Energy’s rebate program offers a range of incentives to support energy-efficient upgrades for homes and businesses. The following rebates are available from July 2025 – June 2026.
Due to the state’s fluorescent lighting ban established under Act 225 (SLH 2023), standard rebates for most LED lighting will end as of March 1, 2026. Businesses are encouraged to act early.
All rebates are available to electric utility ratepayers on Hawaiʻi Island, Lāna‘i, Maui, Moloka‘i and O‘ahu only. Residents and businesses on Kaua‘i are not eligible, as the island is served by a separate utility cooperative. Additional discounts on energy-efficient appliances and water heaters are also available for eligible residents that identify as low-income or are located in geographically-remote areas.
