Maui residents and businesses can now sign up for a Hawaiian Electric program that pays cash to customers with rooftop solar who add extra storage capacity, in an effort to help supply the grid as fossil fuel plants are phased out.

The program pays $850 for each kilowatt of battery capacity committed over a 10-year period — for example, a 5 kilowatt system would yield a $4,250 cash bonus. Customers will also get monthly bill credits over the course of the decade.

The program comes as Maui could be facing more pressure to find more energy sources if it isn’t able to find the parts needed to fix generators at Maui’s Maalaea power plant. Hawaiian Electric might have to close the plant if it can’t secure the spare parts after the parts supplier shut down.
