Hawaii’s Battery Bonus Program
Save Money While Supporting Oahu’s Grid
Powering Oahu with Clean Energy
With the closing of its largest coal plant, Oahu is filling the gap with solar and battery energy storage. But these new systems must be deployed quickly at customer sites to maintain stability on Oahu’s grid.
Consequently, Hawaii’s new energy storage incentives are among the most generous in the nation. For business customers, who typically see 10-30% utility bill savings from onsite battery storage, the up-front cash payment will make storage even more attractive.
The most generous incentives will go to the first projects and then decline. You won’t need to switch your tariff, and your compensation from any existing utility program will remain unchanged.
Beyond monthly bill savings, battery storage helps businesses avoid power outages and maintain smooth operations. Storage is also key for maximizing onsite solar PV by discharging store solar energy when it’s most valuable.
