The installations are projected to save the airport $60,000 annually on electricity.
The Port Authority of New York and New Jersey has unveiled the first of four solar installations at Newark Liberty International Airport.
Officials toured the 152-panel installation located on top of an AirTrain electrical substation on Thursday. A second installation is finished and two more are underway. They're located on two maintenance buildings and a cargo building at the airport.
The Port Authority estimates the four installations will supply the airport with about 817,000 kilowatt-hours per year, or the equivalent of powering 62 homes with electricity or removing 90 vehicles from the road. They're projected to save about $60,000 annually on electricity.
Newark is the first of the Port Authority's airports to receive solar installations. The agency operates JFK, LaGuardia, Stewart, Teterboro and Atlantic City airports.
