Puerto Rico has issued a request for proposals (RFP) to construct 1GW of renewable energy capacity and 500MW of battery energy storage on the island.
The Puerto Rico Electric Power Authority (PREPA) is seeking to procure renewable energy resources with a minimum generating capacity of 20MW, and 500MW of collective energy storage, at least 150MW of which will be distributed virtual power plants (VPPs). A resource that will interconnect to the distribution system cannot exceed 25MW capacity.
The agency said in a public document that it will give preference to energy storage systems with a four-hour discharge duration, but would also consider two and six-hour durations.
