Residential Energy Efficiency Rebate Program

Hawaii Energy rebates help you save on energy-efficient upgrades like heat pump water heaters, air conditioning tune-ups, refrigerators, ceiling fans, and lighting—with water heater switches potentially saving up to 40% on your electric bill. You're eligible if you're a year-round residential electric ratepayer on Hawaii Island, Lanai, Maui, Molokai, or Oahu; apply within 60 days of purchase and expect 6–8 weeks for processing. Visit the Hawaii Energy website to see approved equipment and retailers, or contact them directly for details on available rebates.

You can serve residential customers across Hawaii Island, Lanai, Maui, Molokai, and Oahu through this first-come, first-served rebate program covering heat pump water heaters, HVAC tune-ups, ENERGY STAR appliances, and other efficiency improvements. Ensure your customers are year-round residents, install only program-approved equipment, and submit applications postmarked within 60 days of purchase; check the Hawaii Energy website for the current approved equipment list and any funding restrictions.
