Plus Power Breaks Into Battery Big League With Grid-Tied Project for Hawaiian Electric
Earlier this month Hawaiian Electric announced a slew of solar-plus-storage projects to continue its shift to fossil-free energy. Tucked inside that announcement was a big development: a massive grid-tied battery that will take over crucial duties from the last coal plant anywhere in Hawaii. The 185-megawatt/565-megawatt-hour Kapolei Energy Storage project marks a dramatic arrival to the big leagues for developer Plus Power. Plus power, an ESA member, had previously developed a 12-megawatt battery to ensure reliability at a car factory microgrid in Mexico.
