Environmental Leadership

At Exelon, our commitment to the environment is integral to our corporate strategy.  Our goals are to capitalize on our environmental leadership and provide clean, safe, reliable and affordable electricity that supports America's transition to a sustainable energy future.  

Legacy Exelon 2020 Goal:  In 2012, we achieved more than 89% of our legacy Exelon 2020 goal that was developed subsequent to achieving our Climate Leaders goal, to annually reduce, offset and displace 15.7 million metric tons of GHG emissions. 

Updated Exelon 2020 Goal: Subsequent to our merger with Constellation in 2012, we  have updated  the Exelon 2020 program to include legacy Constellation GHG goals. Our new goal is to reduce, offset or displace 17.5 million metric tons of GHG emissions per year by 2020.

For Exelon, cleaner generation is just part of the equation. We drive our Exelon 2020 program to consider broader environmental, social and economic goals, with the ultimate goal to provide clean, safe, reliable and affordable electricity.

Our environmental success has been recognized with numerous awards including being named to the Dow Jones Sustainability North America Index for the last 9 years and being a continued top performer among utilities under the Carbon Disclosure Project; being named to both the Disclosure Leadership and Performance Leadership Indexes in 2012.

Capitalizing on Environmental Leadership

Exelon’s early commitment to responsible, low-carbon energy investment has enabled us to create advantages for our stakeholders while minimizing our impacts on the environment.  In support of our Exelon 2020 strategy, we plan to invest several billion dollars in cost-effective, clean energy projects from 2010 through 2015. The projects in Illinois, Pennsylvania and other states include energy efficiency and Smart Grid programs, economic renewable and cleaner-burning fossil energy investments, and increased output at Exelon’s nuclear plants.

Greening our Operations

What Are We Doing To Support a More Sustainable Future?

  • In 2012, we formally closed out our internal Energy Use Reduction Challenge with a 30% reduction in commercial building energy use and a 13% reduction in industrial energy use at plants, both from 2001 levels. This far exceeds the respective 25% and 7% reduction goals that were established in 2007. Exelon has received LEED certification for 15 facilities. Some PECO sites are realizing savings of 50% on electricity and gas usage and have reduced water usage by 40%.
  • BGE, ComEd and PECO continue to work to reduce SF6 releases in our transmission and distribution infrastructure through advanced leak detection technology, repairs and replacements.  In 2012, fossil-fuel GHG emissions per mile traveled at ComEd and PECO where 12% lower than 2005 levels. Exelon has become a national leader in supply chain-environmental management through our work with the Electric Utility Industry Sustainable Supply Chain Alliance. Through the Alliance, we have helped lead the development of industry standards for evaluating the environmental attributes of key materials and services as well as performance metrics for supplier companies, including the Alliance’s goal to reduce member supply chain operations energy use by 10% from 2008 by 2015.
Reducing Energy Consumption

How Are We Helping Our Customers & the Communities We Serve Reduce Their GHG Emissions?

By demonstrating that we are aggressively reducing our own emissions, we can help and encourage our customers to reduce their emissions.

  • Exelon plays an important role in helping our more than 6 million energy delivery customers reduce both their monthly energy bills and greenhouse gas emissions.  Our PECO and ComEd Smart Ideas and BGE Energy Saver programs have saved customers almost 10 million megawatt-hours of electricity since 2010, avoiding almost 5.4 million metric tons of GHG emissions.
  • BGE, ComEd and PECO have launched Smart Meter initiatives in Baltimore, Chicago and Philadelphia designed to give customers information and tools to better manage their energy use. 
  • Combined, through the end of 2012, the companies spent more than $690 million and deployed more than 687,000 smart meters, with an additional $2 billion investment to be made through program completion.

Offering Low-Carbon Electricity

What are we doing to offer more low-carbon electricity in the marketplace?

Exelon continues to make important investments in lower-emissions energy generation and reducing the reliance on higher carbon fossil generation.

  • In 2012, Exelon added nearly 500 megawatts of new clean generating capacity, including 63 MW of nuclear uprates, 404 MW of wind and 31 MW of solar power. Overall, the Corporation has invested more than $3 billion in solar and wind generation since 2010.   
  • In September 2011, Exelon announced the acquisition of Antelope Valley Solar Reach One, a 230-MW solar site under development in California. Thirty-one MW of the project became operational at the end of 2012, with the remaining capacity expected to become operational soon.
  • The nuclear uprates program increased output at our zero-emissions nuclear plants by more than 310 MW since 2008 with investment in these uprates of approximately $810 million.
  • We have retired four inefficient, carbon-intensive fossil burning units in Pennsylvania, and added cleaner and more efficient natural gas units through the acquisition of the Wolf Hollow Generating Station in Texas and the merger with Constellation Energy.

Managing our Impact

How are we managing our environmental impact?

We diligently manage our environmental impact on the air, land, water and biodiversity. Our all-source generation portfolio air emission rates are well below industry averages because of our investment in, and commitment to, low-emission technologies for the majority of our owned generating capacity.  In addition, we are challenging the future of energy generation by incorporating land use, water resources, waste generation and community interactions (including affordability and reliability) into our long term business analyses. 

As discussed in detail in the Environmental Sustainability Section of Exelon’s annual sustainability report, Exelon is able to meet energy needs while maintaining the quality of our air, land and water resources and minimizing our impacts on diverse species and habitats.
