Consultants: Faster PV, Storage Roll-Out Possible in Puerto Rico

Puerto Rico has been urged to embrace PV and energy storage more decisively as it works to rebuild its battered power grid, fortifying it against future storms. Siemens’ new advice, submitted to Puerto Rico power regulator PREPA this month, urges the island to roll out 920MW of battery energy storage by 2023. The new figure – revised upwards from the 600-900MW recommended by Siemens in February – would include 400MW of six-hour storage systems and 200MW of two-hour counterparts.
