The Keystone Solar 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 130 submitted. Also, Columbia University School of Business produced a business case study on the project, the first case study in the U.S. on a utility-scale solar project.

Vegetative buffering designed with native grasses, shrubs and trees, allows the solar project to blend into the local landscape. Robust buffering schemes are a key feature of Community Energy’s solar project development.
