Work has been completed on the largest battery energy storage system (BESS) to have been paired with solar PV to date, with utility Florida Power & Light (FPL) holding a ceremony earlier this week. 

US utility Florida Light & Power (FPL) has followed up the US’ first DC-coupled grid-scale battery system with the announcement of a solar-plus-storage project pairing 10MW / 40MWh of energy storage with an existing 74.5MW PV plant.
