The US Department of Energy (DOE) today announced $1.2 billion in financing to replace Puerto Rico’s fossil fuel plants with solar and battery storage through 2032.

The DOE’s Loan Programs Office announced two conditional commitments and one loan closing to power producers in Puerto Rico. Each supports a project contracted with the Puerto Rico Electric Power Authority. The announcements include:

• The closing of a $584.5 million loan guarantee to subsidiaries of Convergent Energy to finance a 100 MW solar farm with a 55 MW (55 MWh) battery energy storage system (BESS) in the municipality of Coamo and BESS installations in the municipalities of Caguas (25MW/100MWh), Peñuelas (100MW/400MWh), and Ponce (up to 100MW/400MWh)
• A conditional commitment for a loan guarantee of up to $133.6 million to a subsidiary of Infinigen for a 32.1 MW solar farm with an integrated 14.45 MW (4.76 MWh) BESS, and a co-located standalone 50 MW (200 MWh) BESS expansion in the municipality of Yabucoa
• A conditional commitment for a loan guarantee of up to $489.4 million to a subsidiary of Pattern Energy for three stand-alone BESS in the municipalities of Arecibo (50 MW/200 MWh), and Santa Isabel (50 MW /200 MWh and 80 MW/320 MW), and a 70 MW solar farm with an integrated BESS in the municipality of Arecibo.

If all are finalized, these projects would more than double LPO’s support for utility-scale solar generation and battery energy storage in Puerto Rico.

LPO provides low-cost financing and a rigorous due diligence process, making it a valuable resource for Puerto Rico as it works to rebuild an affordable, reliable, and clean energy system. As a result of reliance on imported fuel, the persistent threat of tropical storms, and underinvested infrastructure, Puerto Ricans today face average energy costs that are twice the US average – all while consuming only one-quarter of the energy of the US per capita.

LPO’s initial loan to a power producer in Puerto Rico, Project Marahu, closed in October 2024, and when complete will add more than 200 MW of solar and up to 285 MW of stand-alone energy storage to Puerto Rico’s grid.

Through its September 2023 partial loan guarantee to Project Hestia, LPO also supports virtual power plant (VPP)-ready rooftop solar and battery storage installations in Puerto Rico. As a nationwide project, Hestia’s sponsor is committed to at least 20% of installations under Project Hestia going to homeowners in Puerto Rico.

As part of its procurement plan, Puerto Rico Electric Power Authority seeks to install 1,500 MW of battery storage and requires a minimum capacity of storage to be co-located with each utility-scale solar project. Energy storage systems currently online in Puerto Rico are being dispatched every day.

When including Marahu, LPO’s closed and conditionally committed financing supports over 100% of the capacity Puerto Rico Electric Power Authority aimed to procure under its initial request for energy storage project proposals, the first of six.
