Powering a sustainable future starts now

This is a pivotal time for the energy industry—future energy demands must be met with less impact on our climate and with minimal burden on the nation’s economy. To meet these challenges, the Exelon family of companies strives for the highest standards in all aspects of energy, from generation to marketing to delivery.

We are committed to our vision to be the best group of electric generation and electric and gas delivery companies in the United States. Exelon is one of the best run and most profitable companies in the industry. We have the best low-cost, low-carbon generation fleet in the country, which we operate with world-class efficiency.


Our vision includes the following energy goals.

1. Capitalize on environmental leadership and clean nuclear energy

Climate change is real.  In May 2010 the NAS issued a series of new reports that represents that body’s most comprehensive study of climate change to date. NAS confirmed that climate change is occurring, is caused largely by human activities, and poses significant risks for – and in some cases is already affecting – a broad range of human and natural systems.

Public concern about climate change is bringing new demand for environmentally friendly products and services to meet future energy needs and Exelon is leading the way. Exelon’s nuclear fleet, diverse renewable energy portfolio—hydroelectric, wind, landfill gas, solar--and responsible fossil generation position us to reliably and cost-competitively compete in the markets where we operate.

  • Exelon Generation owns four hydroelectric power plants that provide more than 1,800 MW of clean electricity.
  • We invested $62 million to partner with SunPower Corp. to convert an abandoned industrial site on Chicago’s South Side into the nation’s largest urban solar power plant, Exelon City Solar.
  • Currently under construction in northern Los Angeles County, Calif., Antelope Valley Solar Ranch One will be one of the largest PV solar projects in the world when completed, adding 230 MW of solar energy to Exelon Generation's portfolio.
  • Since acquiring 735 MW of wind energy in 2010, Exelon Generation has added an additional 564 MW of wind energy to its porfolio.

2. Run the nuclear fleet at world-class levels

Exelon operates the largest nuclear fleet in the nation. On April 1, 2014, Exelon officially added Calvert Cliffs Nuclear Power Plant in Maryland, and R.E. Ginna Nuclear Plant and Nine Mile Point Nuclear Station in New York to its nuclear fleet, expanding it to 23 nuclear generating units at 14 locations in Illinois, Maryland, Nebraska, New Jersey, New York and Pennsylvania.

  • In 2013, Exelon’s nuclear plants produced 134 million net megawatt-hours of electricity, the highest annual production ever for the fleet. The addition of Calvert Cliffs, Ginna and Nine Mile Point, brings Exelon’s 2013 total net generation to 167.2 million megawatt-hours. The 2013 total is enough electricity to power 19 million typical U.S. homes uninterrupted through the year.

  • The Exelon fleet in 2013 operated at a 94.1% capacity factor, a measure of reliability. Including Calvert Cliffs, Ginna and Nine Mile Point, Exelon’s 2013 average capacity factor was 94.9%. Capacity factor refers to amount of electricity actually produced compared with the theoretical maximum possible.

3. Enhance the value of our generation

Exelon Generation has one of the nation’s largest portfolios of electricity generation capacity with access to more than 35,000 megawatts of owned and contracted electricity, and a nationwide reach with strong positions in the Midwest, Mid-Atlantic and Texas.

  • Exelon’s diverse generating portfolio enables us to be competitive in regional power markets and meet demand during the intermediate seasons and peak periods.
  • Constellation is a leading competitive supplier of power, natural gas, renewable energy, and energy management products and services for homes and businesses across the continental United States, including about two-thirds of the companies listed on the Fortune 100 index. Constellation is committed to providing superior value for its customers, investors and the communities it serves.
  • Between 2008 and 2012, Exelon added 310 megawatts of nuclear capacity at its existing nuclear plants. Cumulatively, since the program’s inception, Exelon’s nuclear power uprates have accounted for more than 4.3 million megawatt-hours of low-carbon generation, displacing an estimated 3.2 million metric tons of greenhouse gas emissions.

4. Keep the lights on and the gas flowing

Exelon’s delivery companies, ComEd in northern Illinois, PECO in southeastern Pennsylvania and BGE in central Maryland strive to be the safest and most reliable utilities in the nation. Our utility customers depend on us to keep the lights on and the gas flowing so we work diligently to enhance our infrastructure and work safely every day.

  • Since 2004, ComEd has invested more than $9 billion to expand, upgrade, and maintain the reliability of its transmission and delivery systems.
  • Since 2006, PECO has invested more than $2.5 billion in its electric and natural gas systems.  This includes maintenance, system performance and capacity expansion projects, all which produce jobs and put dollars back into the local economy. 
  • In 2012, BGE  embarked on a three-year project to upgrade electric and gas meters for BGE residential and small commercial customers.  This advancement in technology will provide new features that will allow customers to forecast bills and better track and manage their energy use.  Smart meter installation will be the first step in BGE’s upgrades to the electric delivery system by implementing communication technology, creating a smart grid.
