WASHINGTON – The U.S. Department of Energy’s (DOE) Office of Energy Dominance Financing (EDF) today announced it has closed a $489.4 million loan to Amanecer Puerto Rico LLC, a subsidiary of Pattern Energy, to lower electricity costs and strengthen Puerto Rico’s electric grid. Thanks to President Trump’s Working Families Tax Cuts Act, the investment is expected to save Puerto Rican families and businesses approximately $312.5 million in electricity costs over the next 25 years while improving grid reliability, strengthening energy security, supporting American manufacturing, and reducing dependence on foreign-controlled supply chains.
"President Trump's Working Families Tax Cuts Act is driving investments that strengthen America's energy infrastructure while lowering costs for hardworking families," said EDF Director Gregory A. Beard. "This investment will strengthen Puerto Rico's electric grid, lower electricity costs, support American manufacturing, and provide a pathway for the reliable, dispatchable power needed to deliver affordable, reliable, and secure energy for the people of Puerto Rico.”
Puerto Rico's grid has experienced chronic outages and prolonged service interruptions that have imposed significant costs on families, businesses, and critical infrastructure. Following a comprehensive review by the Trump Administration, DOE restructured the financing to better align with the Administration's priorities of lowering energy costs, strengthening American manufacturing, and ensuring the deployment of reliable, secure energy infrastructure.
The financing will support:
- 220 megawatts of battery energy storage systems in Arecibo and Santa Isabel using American-manufactured battery technology and secure domestic supply chains.
- Battery storage capable of providing backup electricity for more than 100,000 customers during power shortages and helping avoid approximately 13 million customer interruption hours based on 2025 operating data.
- A pathway for the future development of reliable, dispatchable natural gas-fired generation to improve grid stability and strengthen Puerto Rico's long-term energy security.
This financing builds on the Trump Administration's broader efforts to restore reliable electricity across Puerto Rico. Since 2025, DOE has issued and renewed emergency orders under Section 202(c) of the Federal Power Act to authorize critical generation needed to maintain reliable electric service, while supporting vegetation management and transmission maintenance to improve grid performance ahead of periods of peak demand and hurricane season. Together, these emergency actions and long-term infrastructure investments are helping deliver a stronger, more reliable, and more affordable electric system for Puerto Rico.
Under President Trump’s leadership, EDF is committed to financing American energy and manufacturing projects that meaningfully contribute to U.S. energy security, grid reliability, and lowering costs for all Americans. EDF empowers the private sector to invest in the future, win the AI race, strengthen American industry, and restore American Energy Dominance.
