The Grid Deployment Office's (GDO) Puerto Rico Grid Recovery and Modernization Team works across federal government agencies coordinate billions of dollars in federal aid, provide technical assistance to local stakeholders, and support current rebuilding activities. This team, in coordination with the Department's national labs, led the Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study (PR100), a two-year, comprehensive analysis providing possible pathways for Puerto Rico to achieve its goal of 100% renewable energy by 2050.

GDO also administers the $1 billion Puerto Rico Energy Resilience Fund (PR-ERF), an initiative to improve the resilience of the Puerto Rican electric grid, including renewable energy and storage solutions for vulnerable households and communities. Two key programs are currently administered through the PR-ERF: the Programa Acceso Solar, providing subsidized rooftop solar and battery storage to low-income homeowners across Puerto Rico, and the Programa de Comunidades Resilientes, connecting community healthcare facilities and multifamily housing to solar and battery storage.

DOE also can support large-scale deployment of renewable energy generation and storage in Puerto Rico by providing loans to solar and storage developers. In July 2024, DOE's Loan Programs Office (LPO) announced a conditional commitment for a loan guarantee of up to $861.3 million for its first project of this kind, which will finance the construction of two solar photovoltaic (PV) farms equipped with battery storage in the municipalities of Guayama and Salinas. This project and others like it deliver clean, reliable, and affordable power throughout Puerto Rico.
