Constellation, a subsidiary of Exelon, and the Community College of Baltimore County (CCBC) began construction of a 5.1-MW solar generation project in Baltimore County. The solar power system, spread among the college's three main campuses in Dundalk, Essex and Catonsville, is expected to generate enough electricity to meet approximately 27 percent of the college's electricity needs. Constellation will also install 10 duplex electric vehicle charging stations as part of the project. Constellation will own and operate the CCBC solar power systems. CCBC will purchase the electricity generated by the solar panels from Constellation under a 20-year PPA.
