MECO will pay customers to install batteries!

Owning a solar battery just got better.

The program provides a ‘mail-in rebate’ of $850 for every 5 kilowatts¬†of battery capacity installed by customers – either by adding to existing Net Metered or Customer Grid Supply systems or entirely new Customer Grid Supply systems. For example, a 5kW battery like the Tesla Powerwall 2 will earn a rebate of 5 x $850 = $4,250 per battery enrolled.

Battery Bonus applications will be accepted from Maui customers through June 30, 2024, or until the cap is reached.

Customer Benefits for enrolling in Battery Bonus

Maui solar customers received some excellent news today with the announcement that Hawaiian Electric Company (HECO) has launched its Battery Bonus program on the Valley Isle. 

Customers who sign up for the program will be asked to send energy from their batteries to the utility grid on a daily basis between 6-8.30 pm to help HECO prepare for the future retirement of the Kahului Power Plant. Additional battery storage will also help ensure the continued reliability of electrical supply if four generating units at the Maalaea Generating Station are retired early due to a limited supply of parts.

The program provides a ‘mail-in rebate’ of $850 for every 5 kilowatts of battery capacity installed by customers – either by adding to existing Net Metered or Customer Grid Supply systems or entirely new Customer Grid Supply systems. For example, a 5kW battery like the Tesla Powerwall 2 will earn a rebate of 5 x $850 = $4,250 per battery enrolled. 

The 15-megawatt program is offered on a first come first serve basis to both residential and commercial solar customers. The 15MW capacity is roughly enough for 3,000 homes to enroll 1 Tesla Powerwall into the program. Of course, the more batteries each customer enrolls, the faster the program will fill up.
