Residential solar plus storage is taking over Hawaii’s grid – pv magazine USA
Sunrun is part of a Grid Services Purchase Agreement (GSPA) for 1,000 of its residential solar power and energy storage systems (known as Brightbox), along with third party grid-enabled hot water tanks, to be aggregated into a virtual power plant for purpose of providing grid services to Hawaiian Electric Company (HECO) on the island of O’ahu.
The agreement was signed with Open Access Technology International, Inc. (OATI), who in turn has an agreement in place with HECO. And finally, the utility has submitted it to the state’s Public Utility Commission (PUC). Cash payments will flow from HECO, to OATI, to Sunrun. Sunrun noted that customers who participate in the program will also receive credits on their electricity bills when energy home battery systems feed the grid.
