Can I choose a different natural gas company?

Some Illinois residents and businesses aren't sure if they can select a different electricity and natural gas provider. For electricity, Commonwealth Edison, the main electric company that has served much of Illinois in the past, is the electric utility – this means they own and maintain the infrastructure that brings electricity to your home. However, you are now free to select a different company, such as Spark Energy.

With Natural gas in Illinois, deregulation is similar. Utilities such as Nicor, Peoples, and Peoples North Shore, provide the infrastructure, and Spark Energy provides the natural gas supply.

When you switch to Spark Energy, the utility is still responsible for delivering the electricity or natural gas to your home, and you’ll still call them in case of an emergency or outage. And you’ll still be billed by the utility– Spark Energy will just appear as a line item on the bill.

That’s it. One bill from the same utility. The benefit may be in a lower rate for your energy.

Illinois Electricity and Natural Gas Provider

Illinois residents and businesses have historically had to choose from a single energy company for their energy services – until now. Thanks to deregulation, Illinois has given residents and businesses greater freedom to choose a different energy company.
