Pittsburgh International Airport (PIT), already the first airport in the US to be fully powered by a microgrid, is expanding its solar field with utility Duquesne Light Company (DLC) and solar owner and operator IMG Energy Solutions.
The new solar project will add more than 11,216 panels to the airport’s existing solar array, generating an additional 4.7 megawatts MW) of renewable energy. That’s enough to cut around 5 million pounds of carbon emissions annually. It’s DLC’s first-ever power purchase agreement, and clean energy will go to the regional grid to help power homes and businesses in Pittsburgh.

This expansion will sit on 12 acres of land that used to be a landfill, adjacent to Pittsburgh Airport’s eight-acre solar array, which hosts nearly 10,000 panels. This new and old infrastructure, just off the airport exit from I-376, supports the airport’s 23-MW solar and natural gas microgrid, launched in 2021.
Allegheny County executive Sara Innamorato called the project a “fantastic step” toward a more sustainable future for the region. PIT also has plans to make sustainable aviation fuel onsite.
DLC will use 100% of this project’s energy and Renewable Energy Credits (RECs) to support its default service customers.
“We’re maximizing the use of airport assets for the betterment of the region – from air service to real estate development to energy innovation,” said PIT CEO Christina Cassotis. “And there’s more to come.”
The new solar field is expected to come online by 2027. So if you’re flying into Pittsburgh in a couple of years, you might spot it from your window seat.
