Exelon

Exelon Corporation stands as America's largest electric utility holding company by customer count, serving more than 10.7 million customers through six fully regulated transmission and distribution utilities: Commonwealth Edison (ComEd) in Illinois, PECO Energy Company in Pennsylvania, Baltimore Gas and Electric (BGE) in Maryland, Atlantic City Electric in New Jersey, Delmarva Power across Delaware and Maryland, and Pepco serving Washington D.C. and Maryland. With annual revenues of $23.028 billion in 2024 and a workforce of 20,000 employees, Exelon operates critical energy infrastructure across some of the nation's most densely populated regions.

The company's formation in October 2000 through the merger of PECO Energy Company (founded 1902) and Unicom Corporation (parent of Commonwealth Edison, founded 1907) created a utility powerhouse that has continued to grow through strategic acquisitions. The 2012 acquisition of Constellation Energy Group added significant generation capacity and energy marketing capabilities, while the 2016 acquisition of Pepco Holdings Inc. expanded Exelon's regulated utility footprint into the Mid-Atlantic region. These transformative mergers positioned Exelon as a leader in the regulated utility sector with unparalleled scale and geographic diversity.

In a strategic pivot completed on February 2, 2022, Exelon separated its competitive power generation business, spinning off Constellation Energy to create two focused companies: Exelon as a pure-play regulated utility company and Constellation as the nation's largest producer of carbon-free energy. This separation allowed Exelon to concentrate entirely on regulated energy delivery, transmission infrastructure, and grid modernization, areas where the company has demonstrated operational excellence and strong regulatory relationships.

Under the leadership of President and CEO Calvin Butler, who made history as the company's first Black CEO when he assumed the role on December 31, 2022, Exelon has embarked on an ambitious growth trajectory. The company announced plans to invest $38 billion in capital expenditures over four years (2025-2028), driving expected rate base growth of 7.4% and operating earnings per share growth of 5-7% annually. This investment focuses on grid reliability, infrastructure modernization, and supporting the transition to cleaner energy while maintaining the highest standards of safety and customer service.

Exelon's commitment to operational excellence has earned widespread recognition, with multiple utilities in its portfolio receiving top rankings for economic development, customer satisfaction, and reliability. The company's utilities have achieved top-quartile performance in reduced outage frequency and faster service restoration. Beyond operational metrics, Exelon has distinguished itself through industry-leading diversity, equity, and inclusion initiatives, earning recognition in Newsweek's America's Greatest Workplaces for Diversity and America's Greatest Workplaces for Black Americans, as well as being named to Forbes' list of America's Best Large Employers. The company's culture emphasizes safety, excellence, and inclusion, positioning Exelon as both a utility industry leader and an employer of choice.
