The island of Ta’u in the U.S. territory of American Samoa relied heavily on diesel generation to meet its electricity needs until a “solar+storage” microgrid was installed in 2016. Now, instead of USING 300 gallons of imported diesel fuel every day, the island’s homes and businesses are almost entirely powered by solar+storage. A 1.4-megawatt photovoltaic (PV) and 6-megawatt-hour storage system developed can power the entire island for three days without sunlight and can fully recharge in seven hours. In this webinar, presenters discuss how this project was developed and the impact the microgrid will have on the island’s electric grid and its residents.
