As part of the Biden-Harris administration's Investing in America initiative, the US Department of Energy (DOE) has announced an $861.3 million loan guarantee to support the construction of two solar photovoltaic (PV) farms and two standalone battery energy storage systems in Puerto Rico. The project, named Project Marahu, will provide up to 200 MW of solar energy and 285 MW of battery storage, generating enough power to supply 43,000 homes annually. This initiative is part of the broader effort to modernize Puerto Rico's energy grid, making it more resilient and reducing the island's reliance on fossil fuels, with a target of 100% renewable energy by 2050. The project will also help create 750 construction jobs and more than 50 permanent positions. Once operational, Project Marahu is expected to reduce carbon emissions by nearly 2.7 million tons annually.
