Aerostar begins $13.2M solar project at Luis Muñoz Marín Airport
The system to power Terminal A will be Puerto Rico’s largest airport solar installation.
The project, located at the Luis Muñoz Marín International Airport (airport code SJU), is part of the airport operator’s Sustainability Plan and is expected to reduce power outages, generate operational savings and support long-term environmental resilience, officials said.
The new solar array will be installed on the entire sixth level of the airport’s parking structure. In addition to shading parked vehicles, the system will deliver solar energy directly to Terminal A.
According to Aerostar, the installation will cover a significant portion of the airport’s energy demand, including critical infrastructure such as air conditioning. The airport currently incurs more than $1 million in monthly electricity costs.
“This project marks a firm step toward a more sustainable, efficient and resilient operation,” said Jorge Hernández, president of Aerostar Puerto Rico. “At Aerostar, we are committed to leading by example and demonstrating how investment in clean energy can result in real benefits for our passengers, employees and for Puerto Rico.”
The Federal Aviation Administration (FAA) allocated $5 million, with Aerostar covering the remaining $8.2 million. The project is expected to be completed by the end of 2025.
“We know that operating Puerto Rico’s main gateway comes with great responsibility. That’s why at Aerostar we make no compromises when it comes to implementing solutions that support the collective well-being and the future of the island,” Hernández added. “Investing in sustainability is investing in progress, and we are fully aware of the long-term positive impact this project will have.”
The solar project is one of 18 energy initiatives outlined in Aerostar’s broader Sustainability Plan, which includes 67 measurable actions aimed at improving environmental performance and achieving energy independence.
“This project is not only a redundant energy source that strengthens the airport’s operations, but it also enables us to reduce our carbon footprint and move toward achieving Level 3 of the Airport Carbon Accreditation program by 2027,” said Jaime Pabón, Aerostar’s director of sustainability.
The installation will also contribute to global decarbonization goals set by the Airports Council International (ACI). SJU was recently awarded Level 2 in the ACI’s environmental accreditation program, recognizing its progress in sustainability.
Hernández said the project represents a model for innovation and leadership in the airport industry.
“It is possible to combine operational efficiency, economic savings and environmental commitment,” he said.
