The Exelon Generation portfolio is unique in its diversity of geography, markets, fuels and technologies and includes:
- Nation’s largest commercial nuclear fleet, which ensures dependable low-carbon baseload (around-the-clock) power supply
- Wide range of company-owned fossil, hydroelectric and renewable facilities, to diversify our fuel mix and help meet peak demand periods
- Landfill Gas
Exelon Generation is heavily invested in low-carbon nuclear energy, operating the largest nuclear fleet in the nation and the third largest fleet in the world.
- With 10 generating power plants and 17 reactors - located in Illinois, Pennsylvania and New Jersey - Exelon Generation produces enough clean-air nuclear energy to power millions of homes.
- Nuclear power plants emit virtually no greenhouse gases and supply about 20% of the nation’s electricity needs.
Exelon Generation owns Conowingo Hydroelectric Generating Station and the Muddy Run Pumped Storage Facility which together produce more than 1,600 MW of hydroelectric power. Exelon also has ownership interest in two additional hydroelectric power plants located in Pennsylvania and California.
- Water flow from the Susquehanna River powers Conowingo’s 11 turbine generators, which produce 572 MW - enough energy to power more than 400,000 homes.
- Muddy Run pumps water into a reservoir during off-peak hours and uses that water to generate electricity during peak demand hours. The facility produces over 1,000 MW.
- Exelon has a 67 percent (277.7 MW) ownership interest in Safe Harbor, which is a run-of-the-river hydroelectric facility located on the Susquehanna River in Conestoga, Pennsylvania. Exelon also has a 50 percent (16 MW) ownership interest in Malacha, a pumped storage hydroelectric facility located in McArthur, California.
Exelon Generation owns and operates the nation's largest urban solar power plant in Chicago and is currently constructing one of the largest solar projects in the world in southern California.
- Exelon City Solar is a 10-megawatt solar installation located on a 41-acre brownfield in Chicago’s West Pullman neighborhood. It captures the sun’s rays and converts them into 14,000 megawatt-hours of electricity per year. The facility was completed in 2010.
- Antelope Valley Solar Ranch One is a 230-meagwatt solar photovoltaic (PV) project under construction in northern Los Angeles Couty, Calif. When fully operational, AV Solar Ranch One will be one of the largest PV solar projects in the world with approximately 3.8 million solar panels.
- Exelon also has an ownership interest in California's Solar Energy Generating Systems (SEGS) IV, V and VI, which is equivalent to 8 MW.
Exelon Generation owns and operates 44 wind projects that in total are capable of generating nearly 1,300 MW.
- Exelon Generation’s owned and operated wind projects are located in 10 states.
- The first commerical wind project constructed by Exelon Generation, Michigan Wind 2, went online in Jan. 2012.
Exelon Generation owns a landfill gas power plant located in the northern suburbs of Philadelphia.
- Fairless Hills Generating Station in Fairless Hills, Pennsylvania has 2 units that use landfill gas from 2 local landfills as its primary fuel source to produce 60 MW of electricity inside the USX Industrial Complex.
Exelon Generation’s fossil portfolio consists of over 12,000 MW of capacity produced by coal, oil and natural gas power plants.
- Its baseload, intermediate and peaking plants, which are needed only during periods of peak demand, are located in Alabama, California, Illinois, Maine, Maryland, Massachusetts, Pennsylvania, Texas, Utah and Alberta, Canada.
Generation Operating Companies
Exelon Generation is comprised of two primary business units—Exelon Nuclear and Exelon Power.
- Exelon Nuclear operates the largest fleet of nuclear power plants in the nation and the third largest fleet in the world.
- Exelon Power is responsible for managing, operating, and maintaining the company’s fossil (coal, oil, and natural gas), renewable (landfill gas, wind and solar) and hydroelectic fleet of generating assets. Exelon Power can provide over 15,000 MW of safe, efficient and environmentally responsible baseload, intermediate and peak power generation.
Exelon Generation’s environmental vision mirrors that of its parent company, Exelon, to constantly improve our environmental performance. All operating companies are committed to setting measurable goals, achieving credible results and implementing cost-effective environmental improvements.
In 2008, Exelon set a goal to reduce energy consumption in its commercial facilities by 25% and in its power plants by 7% by the year 2012 (from a 2001 baseline). By the end of 2009, we had reduced energy use at our commercial facilities by 23.8% and auxiliary power use at our plants by 6.6%. These energy reductions correspond to a total GHG emissions reduction of nearly 145,000 metric tons.
As part of Exelon 2020, Exelon Generation has reduced energy use at our facilities through a variety of projects including:
- An extensive building renovation at the Conowingo Visitor Center, including a 3.2 kilowatt solar array, earning it LEED-Existing Building Gold Certification
- Replacement of a 45-year-old lighting system at the Fairless Hills Generating Station, resulting in an 80% energy savings per year
- Extensive lighting replacements at power plants; and
- Continuation of the work of the Kennett Square Environmental Council, which drove a number of initiatives including shuttle service between Philadelphia and Kennett Square, electric and water reduction best practices and recycling programs.

At Exelon, our goals are to capitalize on environmental leadership and low-carbon nuclear energy and to run our nuclear fleet at world-class levels. Exelon Generation’s operating excellence is central to our continuing success.
- Optimizing Clean-Air Generation: Exelon’s nuclear fleet achieved an average capacity factor of 92.7% in 2012, the tenth consecutive year it exceeded 92%. We produced about 140 million megawatt-hours (MWh) of electricity while emitting virtually no greenhouse gases (GHG).
- Investing in Reliable Operations: Exelon Power’s fleet of fossil, renewable and hydroelectric units in 11 states provided over 11.5 million MWh of generation in 2011.
All Exelon facilities employ sophisticated emergency response plans to protect public health and safety. These plans are reviewed and approved by state governments and federal agencies such as the Nuclear Regulatory Commission (NRC). The emergency planning includes coordination with local counties, municipalities and school districts.
Our power plants aim to be good neighbors within their local communities with active involvement through sponsorships, charitable giving and volunteering. They sponsor local events to support the environment, education, the arts and diversity. We encourage our employees to give back to their communities and we recognize their efforts through various programs such as matched gifts and volunteer grants to the organizations they serve.
