Puerto Rican regulators have ordered PREPA to procure solar and storage, but the utility’s board chairman says that the island’s grid can support only a fraction of the mandated amount.
The Puerto Rico Energy Bureau has ordered utility PREPA to issue six procurements in the next 30 months, totaling 3.75 GW of solar and 1.5 GW of four-hour storage, or their equivalents. PREPA will issue the first of the six procurements “As early in 2021 as possible,” the utility said in a regulatory filing. Regulators had set a target release date of last December for that first procurement, to secure 1,000 MW of solar and 500 MW of storage.
A study released by PREPA in mid-January concludes that Puerto Rico’s grid can handle only 650 MW of utility-scale renewable generation, including existing renewables. “Amd the bureau understands that it must be 1,000.”Kreil added that PREPA’s request for proposals will call for 1,000 MW of solar.
