A growing portfolio of solar energy projects

Exelon Generation owns and operates the nation's largest urban solar power plant, Exelon City Solar in Chicago, and is currently developing a 230-megawatt solar plant in California.

Southern California Solar
Exelon Corporation has acquired Antelope Valley Solar Ranch One, a solar PV project in northern Los Angeles County, from First Solar. When completed, it will generate enough clean, renewable electricity to power the equivalent of 75,000 average homes and displace the carbon emissions of 30,000 cars per year.

Solar Investment
