Utilities

Electric and Natural Gas Providers

While you can change your supplier, you can’t change your utility. So, no matter who supplies your energy, your utility will still be responsible for delivering it to you. You can read more about your local electric and natural gas utilities and what they do below.

What is a Utility?

The utility maintains all the electric wires and gas pipelines that ensure the safe and reliable flow of energy to your home or business. It will also provide you with a default energy plan if you don’t sign up with a competitive energy supplier.

Electricity and natural gas suppliers purchase energy and resell at competitive rates to homes and businesses.

Public utilities can be privately owned or publicly owned. Publicly owned utilities include cooperative and municipal utilities. Municipal utilities may actually include territories outside of city limits or may not even serve the entire city. Cooperative utilities are owned by the customers they serve. Private utilities, also called investor-owned utilities, are owned by investors.
