The largest solar project in Pennsylvania, built on more than 1,755 acres of former farmland, is producing power in central Pennsylvania. The Great Cove Solar Project by AES Corporation, a global energy company based in Arlington, VA, involves two sites in Franklin and Fulton counties that have begun producing 220 megawatts of electricity. According to the Solar Energy Industries Association, that’s enough to power approximately 38,060 homes. Energy production began in December.
