Additional information

Energy storage solution called SEA-Power (SEAP). SEA-Power(SEAP) is a patented Lithium battery technology, the Lithium battery-based power storage & management system that responds within milliseconds to frequency fluctuations by releasing or absorbing power from the electricity grid and the solar farm. Each SEAP consists of 4 MW battery storage and Battery Management System (BMS), fire suppression equipment, thermal management system, switchgear, UPS, and house power. Each module consists of 60 banks of battery blocks housed in individual 40-foot containers.
