Clean, Reliable and Affordable

Offering more low-carbon electricity in the marketplace is a critical element of Exelon's climate change response. We’re optimizing our systems to maximize competitively-priced, low-carbon generation that can displace higher-emitting fossil generation and help to transition America to clean, safe, reliable and affordable electricity.

Exelon offers more low-carbon electricity in the marketplace than any other power producer in the nation.  In 2013, more than 81% of our generation output was low-carbon nuclear energy, complemented by a growing portfolio of carefully selected solar, wind and hydroelectric generation.  The foundation of our corporate strategy is to focus on safety of operations, clean generation, reliability of supply and affordability for our customers.  In balancing these elements, we strive to lead the United States to a low-carbon energy future.   

Exelon's Climate Change Response in Action

We are committed to offering more low-carbon electricity in the marketplace by increasing the output of our nuclear fleet, investing in other low-emission energy generation and reducing the reliance on fossil generation.  Our progress includes:

Reliable, Low-Carbon Nuclear

  • Nuclear energy has an integral role in supporting our economy; it delivers safe, clean and affordable energy and emits virtually no greenhouse gases. In 2013, Exelon achieved a 94.1% capacity factor at Exelon-operated nuclear plants.

Increasing Efficiency of Fossil Generation

  • Exelon continues to retire older, inefficient fossil-fuel generating capacity such as generating units at Cromby and Eddystone in 2012 and Schuylkill in 2013.
  • We are continuing to maintain the quick-starting fossil generation capability within our fleet through the acquisition of cleaner, more efficient natural gas-fired combined-cycle generation stations.  Natural gas emits 80% less sulfur dioxide and nitrogen dioxide, and 55% less carbon dioxide than coal.

Increasing Renewable Energy

  • Exelon currently utilizes 753 wind turbines capable of generating 1,298 megawatts of power and owns 359 megawatts of solar power, including the 230MW Antelope Valley Solar Ranch One project in California that will be completed in 2014.
