Enphase Energy collaborated with Hawaiian Electric to clear the backlog of solar customers awaiting interconnection on the island of Oahu.
After making a commitment in October 2014 to clear 90 percent of its interconnection backlog by April 2015, Hawaiian Electric sought out Enphase’s technical assistance to get a detailed analysis of grid conditions in every neighborhood across the island. About 25,000 Enphase systems have been installed on Oahu and represent about 70 percent of all PV system production on the island.
The Enphase PV systems are able to report high-granularity voltage and frequency data. The two companies used this PV production data to create statistically rich “heat maps” that supported the initial technical reviews by Hawaiian Electric’s engineers. The analysis provided by Enphase helped Hawaiian Electric meet its commitment to approve about 4,000 PV systems, or over 20 MW, of solar interconnections.
