How HECO is Using Enphase’s Data to Open its Grid to More Solar

HECO solarOn the island of Oahu, Hawaiian Electric Co. is opening a backlog of about 4,000 customer solar systems it once feared could destabilize its distribution circuits. That move is being helped along by Enphase microinverter data that can provide a much clearer view of what’s really happening on the edges of HECO’s grid.

On Tuesday, Enphase revealed details on a months-long collaboration with HECO to map out how customer-owned rooftop solar affects its distribution grid on a circuit-by-circuit basis. The results have allowed HECO “to clear nearly all of the backlog of customers awaiting approval to interconnect their rooftop solar systems in a safe and reliable manner,” Jim Alberts, the utility’s senior vice president of customer service, said in a prepared statement.
