PECO was once Philadelphia Electric.

Avalon - PECO was once Philadelphia Electric. They now own AC Electric, PEPCO, Delmarva Power, and others. They used to generate their own power via power plants. They have sold all of the generation to Constellation and others. So, AC Electric has little to no control over what they must now pay simply to transmit power to you. And you must bear that rate increase. There is one way to control generation of power to your home, and that one way, is solar panels. It’s your choice.
