​​Advancing smart energy to provide safe, reliable, affordable and clean energy and energy services for our customers and the communities we serve.​

With a history of more than 130 years of service to the Greater Philadelphia region, PECO has a long-standing commitment to a culture of excellence. Formerly, Philadelphia Electric Company, PECO was incorporated in 1902 but finds it origins in The Brush Electric Light Company of Philadelphia, which was formed in 1881. One of the oldest and largest utility companies in the United States, PECO has its origins in the work of Thomas Edison.

As invention brought new conveniences, population grew and industry developed, PECO grew to meet the increasing demand of its customers. The history and evolution of electricity and natural gas development, distribution and consumption suggests that demand for both will continue to increase. PECO is the steward of efforts to help customers make better choices about energy usage and is focused on setting the example as an environmental leader.
