How Electricity Choice Works in Mercer County

Your utility and your supplier are different.

In Pennsylvania's deregulated electricity market, the company that delivers power to your home is separate from the company that sells you the electricity itself. In Mercer County, Penn Poweris the distribution utility for every customer — but you have the legal right to choose your supplier from over 100 licensed competitors. Switching suppliers doesn't change Penn Power's service, your wires, or your reliability — only the generation portion of your bill changes.
