What Is Nicor Gas?

Nicor Gas is Illinois’ largest natural gas utility. Its origins trace back to 1855, but its modern history began in 1958 when it established its first storage field for natural gas. Today, the company delivers gas to more than 2.3 million customers through its eight underground storage facilities and connections to more than 34,000 miles of gas pipelines.

Nicor Gas serves customers in 31 northern Illinois counties. If you live in Nicor’s service area, you’ll automatically receive your gas from the utility. However, thanks to energy deregulation in Illinois, you can choose your provider, even if Nicor still delivers the electricity.

You have the power to choose in Illinois

In 1997, Illinois passed legislation that gave consumers the power to shop for competitive natural gas rates. Instead of requiring consumers to pay Nicor Gas supply rates, Illinois allows its residents and businesses to compare supply rates and search for a different offer.

If you find a good deal, you can stop purchasing your gas directly from Nicor Gas without penalty. As per the energy choice law, the utility is required to deliver energy to your home, regardless of which supplier you choose. 

If you decide Nicor Gas supply rates aren’t right for you, the utility will still provide its essential services, which include maintaining the natural gas pipelines and ensuring you receive natural gas.

How do you report a gas leak in northern Illinois?

In an energy choice market, you have the ability to pick your energy plan. Illinois residents and businesses can choose from a wide range of electric and gas providers. While you get to choose a retailer who supplies your energy, the local utility remains responsible for the transmission and delivery of that energy.

Nicor Gas operates all gas lines within its service area. Illinois residents in its service territory should notify the utility immediately of any natural gas safety concerns. Once you’ve called Nicor Gas, the utility can dispatch crews to fix the problem and restore service as quickly as possible.
