We remain focused on improving the reliability and resilience of Puerto Rico’s electric grid, enhancing emergency preparedness, and delivering better service to our 1.5 million customers. This page showcases real stories that reflect that commitment, projects that transform infrastructure, initiatives that empower communities, and advancements that light the way toward a safer, more modern, and efficient energy system.
Every day, we’re working to strengthen the grid, improve reliability, and deliver safer, more dependable service for our communities in Puerto Rico. Here are some of the projects making a real difference across the island.
In Puerto Rico, more than half of the transformers in substations have exceeded their useful life and maintenance cycle.
After a multi-year acquisition and design process, the largest transformer ever to arrive in Puerto Rico reached the island at the end of 2025. Once this transformer is fully energized at the Sabana Llana substation in early 2026, it will benefit more than 700,000 of our customers across the island by providing greater stability and helping prevent large-scale outages.
Throughout 2026, additional transformers will continue to arrive, marking a significant milestone in LUMA’s efforts to stabilize the island’s electric system.
We’re continuing the work to rebuild Puerto Rico’s electric system and strengthen reliability for our communities.
Our crews are currently restoring five major transmission lines that have been out of service since Hurricane Maria.
Right now, we’re focused on rebuilding a line in the eastern region that connects the Naguabo TC substation to Verde Mar in Humacao, a line that has been out of service since Hurricane Maria. Although historical resource limitations and the severely deteriorated state of the system made it difficult to address this project immediately, we remained committed to completing it. This line is essential for providing redundancy to the electric system that serves more than 25,000 customers in Naguabo, Humacao, Vieques, and Culebra. Once the line is back in service, outage frequency will be significantly reduced, improving reliability across the eastern region.
As part of the reconstruction work, crews replaced critical components on existing poles, ensuring greater reliability once the line is energized.
Each of these projects reflects our commitment to rebuilding Puerto Rico’s electric grid and delivering a more reliable system for all our customers.
We continue working with FEMA to advance critical projects that strengthen the safety and reliability of Puerto Rico’s electric system. In addition, we’ve streamlined our processes to request and receive federal funds more efficiently, supporting our joint efforts with FEMA.
As part of this initiative, our crews have cleared vegetation along more than 257 miles of transmission lines in the Mayagüez, Ponce, Caguas, and Arecibo regions, areas where overgrown vegetation poses safety risks and can cause service interruptions.
Teams from LUMA, FEMA, the Puerto Rico Electric Power Authority (PREPA), and other partners regularly coordinate to monitor progress, share updates, and ensure all work complies with federal and local regulations.
This FEMA-funded effort complements our ongoing vegetation management program. While our regular program addresses day-to-day trimming needs, the FEMA-supported initiative focuses on clearing corridors that have been overgrown for years in high-priority areas, helping reduce outages and improve service reliability for communities across the island
In 2025, we began installing approximately 1.5 million smart meters throughout Puerto Rico. These new devices will enable the collection of accurate, real-time data, allowing for faster outage detection and more efficient service restoration. In addition, they will help reduce estimated readings and promote the integration of renewable energy sources.
Since June 2025, we have made substantial upgrades to the Crea substation in Bayamón, as well as to the Las Piedras, Guánica, and Aguada substations, to improve service reliability for more than 30,000 customers.
Each improvement project involved a series of essential tasks, including conducting a thermographic study to identify hot spots on the connected transmission line, all of which were corrected. Vegetation management was also carried out in critical areas to minimize the risk of future outages. Additionally, lightning arresters were installed, and animal guards were placed on power lines to reduce the risk of wildlife coming into contact with the infrastructure.
In 2025, we successfully integrated LiDAR (short for Light Detection and Ranging) technology into our aviation and ground patrol operations as part of our ongoing efforts to enhance system monitoring. Similarly to how radar uses radio waves, the advanced LiDAR tool captures detailed environmental information using laser light pulses sent from sensors mounted on drones, helicopters, vehicles, and/or ground-based equipment. To date, we have flown over approximately 33% of the miles of transmission lines and have inspected more than 17,100 structures with the new technology.
The LiDAR data collected is used to generate accurate 3D maps of terrain, structures, and electrical infrastructure, even in complex or hard-to-access conditions. We use this technology for power line design and modeling, determining topography in areas with dense vegetation, assessing right-of-way intrusions, and performing vegetation mitigation near power lines, among other essential tasks. Ground-based LiDAR also enables the inspection of underground systems, detecting risks or maintenance needs.
In 2025, we renewed a collaborative agreement for the third consecutive year to continue offering educational workshops on electrical safety to fifth-grade students in Puerto Rico’s public schools.
The sessions cover topics such as identifying energized power lines, safety rules inside and outside the home, and the emergency number to call, among others. This effort has benefited more than 35,000 students over the past two years.
For the past four years, we have supported the Red Cross Disaster Response program, providing immediate assistance to people affected by home fires, floods, storms, and hurricanes.
Thanks in part to this collaboration, since 2021 more than 4,500 employees have completed over 39,000 hours of emergency response training.
As part of the partnership with the American Red Cross, we host events like the one held at the Carlos Escobar López Municipal Center in Loíza at the end of August. During the event, more than 40 residents received information on how to respond to emergencies involving power lines, accident prevention measures, and tips to stay safe during severe weather events.
During the holiday season, the “Light Up Your Community” campaign has promoted local tourism in Puerto Rico and strengthened community collaboration through various events, including a vote for the favorite municipal decoration.
Through this initiative, $30,000 in donations were awarded in 2025 to six grassroots nonprofit organizations: Asociación Pro-Juventud y Comunidad de Barrio Palmas, Proyecto Casa Elda, Hogar Mis Primeros Pasos, Escuela Montessori San Cristóbal, Proyecto Amor que Sana, and the Centro de Adultos y Niños con Impedimentos (CANII).
As part of efforts to modernize Puerto Rico’s public lighting system, since 2024 we have installed hundreds of lights designed to minimize light pollution and protect marine life, particularly sea turtles, in key coastal areas, in collaboration with groups such as 7 Quillas.
Amber-colored lights make it easier for sea turtles to nest on beaches, unlike white lights, which disorient them away from the shore and prevent nesting.
Despite challenges faced by the Puerto Rico government in maintaining emergency response accounts at sustainable levels, we have continued implementing improvements and adjustments to our Emergency Response Plan, in accordance with federal NIMS (National Incident Management System) standards and the Incident Command System (ICS), ensuring a rapid, safe, and organized response to any emergency. The plan also includes communication protocols with the Puerto Rico Emergency Management Agency and the U.S. Department of Energy (DOE).
Some of the tactics outlined in the plan include pre-positioning crews in key locations as soon as weather conditions allow, to speed up damage assessments and subsequent repairs. As part of the plan, a multi-sector drill was conducted in February to practice response to a Category 5 hurricane alongside local Puerto Rico agencies. Six additional training exercises were also carried out with regional operations centers using the WebEOC tool, a system that enables emergency coordination and real-time information sharing across the organization.
As the transformation and improvement of Puerto Rico’s electric system continues, LUMA Energy reinforces its commitment to the professional development of future energy experts. Since the launch of its internship program, more than 200 students have participated in hands-on learning experiences within the company. Partnerships with universities and academic programs allow students to gain practical experience that fosters innovation while addressing the challenges faced by the electric system.
Several of our interns have been honored with the prestigious IEEE PES PLUS scholarship, a recognition that highlights their dedication and academic excellence in the field of electrical engineering.
