The project was the recipient of the PV America East 2013 Project of Distinction Award. This is a national award that recognizes major achievements in the U.S. solar market. Keystone Solar was one of three projects selected out of more than 100 submitted. Columbia University School of Business produced a business case study on the project, the first such case study in the U.S. on a utility scale solar project.

The ground-mounted installations were developed by Community Energy Solar and constructed by groSolar. Community Energy worked closely with the fabled Lancaster County farming community and township officials in designing the project to support both farmland preservation and agricultural soil restoration. The solar panels were installed on driven posts without concrete to avoid soil disturbance, such that the site will be maintained with selected cover vegetation to preserve and improve organic soil content.

Producing six megawatts of solar power, the solar farm will generate approximately 8,000 MWhs of clean, fuel-free electricity a year — enough to power over 950 homes from this single solar field. Keystone Solar is the largest customer driven utility-scale solar project in PA. Exelon Generation and Community Energy’s retail marketing division committed to buy the output and back the financing for the project, which will supply the highest-quality green electricity – local solar power – to customers who sign up for a share of the generation. Several high-profile customers have already signed up for a share of the renewable energy credits, including Franklin & Marshall College, Eastern University, Clean Air Council, the Philadelphia Phillies, Millersville University, Drexel University, and most recently, Marywood University and Juniata College.
