Constellation, a business unit of Exelon Corp., has commissioned a 16.1 MW grid-connected photovoltaic installation in Emmitsburg, Md. The project is part of the state's Generating Clean Horizons initiative.
Constellation financed, owns and operates the approximately $50 million solar facility on behalf of its customer, the state of Maryland. Electricity generated by the system is purchased by the state's Department of General Services and the University System of Maryland under 20-year power purchase agreements (PPAs) with Constellation.
According to Constellation, the installation is expected to produce more than 20 GWh of electricity annually. It was constructed by First Solar, using approximately 220,000 modules situated on 100 acres of land leased by Constellation from Mount St. Mary's University. Constellation additionally developed a 1.6 MW solar system on the site that will supply power directly to the university.
In February 2009, the Maryland Energy Administration, in partnership with the University System of Maryland and the Department of General Services, approved the award of four renewable energy projects under the Generating Clean Horizons program.Â The initiative was intended to spur the development of large-scale, commercial renewable energy projects, and the state issued requests for proposals for long-term PPAs from renewable sources delivering clean power to the grid by 2014.
