Commonwealth Edison (ComEd)
Commonwealth Edison Company, commonly known as ComEd, is the largest electric utility in Illinois and one of the largest in the United States, providing electricity to approximately 4.1 million customers across northern Illinois including the Chicago metropolitan area. A subsidiary of Exelon Corporation (NASDAQ: EXC), ComEd operates as a regulated electric transmission and distribution utility under the oversight of the Illinois Commerce Commission, which sets the rates and terms under which ComEd provides electric service to residential, commercial, and industrial customers. According to its website at comed.com, ComEd is committed to delivering safe, reliable, and affordable electricity to its customers while investing in a smarter, stronger energy grid that supports Illinois' clean energy goals and the state's economic vitality.
ComEd's grid modernization and clean energy investment program, as described at comed.com, encompasses the continued deployment of smart meters and smart grid technology across its service territory, investment in electric vehicle charging infrastructure, development of community solar and distributed energy resources, and major capital projects to improve transmission and distribution reliability and capacity. The Illinois Future Energy Jobs Act and the Climate and Equitable Jobs Act have provided a constructive regulatory framework for ComEd's clean energy and grid investment programs, establishing mechanisms that allow the utility to earn a timely return on its infrastructure investments while delivering meaningful consumer benefits and advancing the state's clean energy and equity objectives. ComEd's multi-year capital plan reflects billions of dollars in planned investment in the Illinois electric grid.
ComEd's affiliation with Exelon Corporation — which operates the nation's largest fleet of nuclear power plants and serves approximately 10 million electric and gas customers across six Mid-Atlantic and Midwest utilities — provides ComEd with access to the operational expertise, technology resources, and financial strength of the nation's largest regulated utility holding company. According to comed.com, ComEd benefits from Exelon's scale in supply chain management, technology deployment, nuclear expertise, and regulatory strategy while maintaining its local focus on delivering high-quality electric service to the millions of customers in its northern Illinois service territory. ComEd's combination of large customer base, significant grid investment opportunity, constructive Illinois regulatory framework, and Exelon backing makes it a significant and consequential participant in both the Illinois energy market and the national electric utility sector.
