LLI Engineering’s microgrid and solar field power a new era of sustainability at Pittsburgh International Airport
PITTSBURGH - As Pittsburgh International Airport prepares to open its new terminal this November, sustainability remains a central theme—powered in part by the innovative microgrid and solar field designed by LLI Engineering.
The 20 MW microgrid, which began operating in 2021, supplies 100% of the airport’s power, making it the first airport in the world to be entirely powered by its own energy sources. The system integrates natural gas-fired generators and more than 9,000 solar panels across an expansive field on airport property.
LLI Engineering design and engineering for the microgrid and solar field infrastructure, ensuring the system's seamless integration with airport operations and long-term resiliency. The design also left room for expansion, with plans to more than double the number of panels by 2027.
With sustainability at the core of the $1.7 billion terminal modernization program, the microgrid and solar field exemplify how advanced engineering can meet the demands of both innovation and environmental stewardship.
