US DOE closes $489.4m loan to support Puerto Rico BESS projects

SolarNews Brief

The US Department of Energy closed a $489.4 million loan to Amanecer Puerto Rico, a Pattern Energy subsidiary, to support Puerto Rico's electric grid. The financing will support 220 MW of battery energy storage systems in Arecibo and Santa Isabel as well as future natural gas generation development.

The DOE loan was closed through the Office of Energy Dominance Financing and is aimed at lowering electricity costs and strengthening Puerto Rico's grid. Energy-Storage.News reports the financing will support 220 MW of BESS across Arecibo and Santa Isabel, with DOE estimating about $312.5 million in electricity-cost savings over 25 years. The package is important for grid resilience, though it also reflects a policy shift because some earlier Puerto Rico solar-and-storage funding has been redirected toward fossil-fuel plants.
