LUMA Energy's role in the crisis
In 2018, the Puerto Rican government privatized the entire electric grid, which was previously distributed by the state-owned Puerto Rico Electric Power Authority (PREPA). PREPA had gone bankrupt, leaving behind $9 billion in unpaid debts. The government contracted LUMA Energy, a private consortium, to manage electricity transmission and distribution.
LUMA Energy is a joint venture between Houston's Quanta Services Inc. and the ATCO Group of Alberta, Canada. The company signed a 15-year contract and took over operations on June 1, 2021.
LUMA Energy has faced significant challenges since taking over, including widespread power outages that have prompted emergency declarations by multiple mayors. The company has cited pre-existing grid damage, weather, and possible sabotage as causes. The Puerto Rican government had hoped that privatization would improve the electrical grid, but the situation has seemingly deteriorated further. LUMA has been criticized for failing to incorporate more renewable energy sources into the grid, with only about 4% of power distributed being renewable.
Despite these challenges, LUMA has made some efforts to improve the situation. The company has overseen power restoration following severe weather events such as Hurricane Fiona in 2022 and Tropical Storm Ernesto in 2024. They have also connected solar panel systems for 12,000 customers, adding 50 MW of solar capacity to the grid. Additionally, LUMA has plans to expand Puerto Rico's electric grid with nearly 1 gigawatt (GW) of renewable energy and over 700 megawatts (MW) of energy storage.
Overall, while LUMA Energy's role in the Puerto Rico electricity crisis has been controversial, the company has faced significant challenges and has made some efforts to improve the situation. However, there is still much work to be done to achieve the island's renewable energy goals and improve the reliability of the electrical grid.

Solar power as a backup
Puerto Rico has been struggling with power outages and an unstable electricity supply for years, with residents experiencing power cuts several times a week. The situation has been caused by a variety of factors, including hurricanes, tropical storms, bureaucratic issues, and mismanagement and disinvestment in the island's grid infrastructure.
In the face of these challenges, Puerto Rico has turned to solar power as a backup solution. Solar panels are designed to withstand hurricane-force winds and can provide a critical source of electricity when the power grid fails. After Hurricane Maria devastated the island in 2017, residents launched community-based solar projects to keep the lights on, and solar-plus-storage systems are being installed across the island.
One successful example is the town of Adjuntas, which has implemented a combination of experimental microgrids, solar panels, and storage. When power outages affected the rest of Puerto Rico in April 2025, Adjuntas remained largely unaffected, demonstrating the effectiveness of their solar setup.
The U.S. Department of Energy has also recognized the potential of solar power in Puerto Rico, announcing funding of up to $440 million for rooftop solar installations and batteries in vulnerable communities. This funding will help lower energy bills, improve resilience, and support local clean energy jobs. However, there has been criticism of the department's decision to redirect $365 million away from solar initiatives towards grid fixes.
Solar power has provided Puerto Rico with a measure of energy independence and resilience in the face of frequent power outages. With the increasing intensity and frequency of severe weather events due to climate change, solar power is likely to play an even more crucial role in ensuring a stable and sustainable energy future for the island.
