About Nicor Gas

For more than 160 years, Nicor Gas has been serving Illinois customers with clean, safe, reliable and affordable natural gas. As the state’s largest natural gas distributor, and owner and operator of one of the largest natural gas reservoir storage systems in North America, we deliver the comfort and convenience of natural gas to 2.3 million residential, public sector and business customers in more than 650 communities throughout northern Illinois.

With 2,000 employees constructing, operating, maintaining and inspecting our nearly 34,000-mile distribution system, the safety of our employees, the public and our pipelines is our highest priority. This commitment is demonstrated in our rigorous operating standards, safety training and monitoring, and our effort to continuously meet and exceed all state and federal regulations.

As an important contributor to the Illinois economy, we are dedicated to investing in programs and initiatives that enrich the community, enhance diversity, invigorate the economy, promote education and support environmental stewardship. We leverage our assets and resources to improve the quality of life for the communities where we live, work and serve.

Keeping Gas Prices Down

Nicor Gas customers are connected to a 34,000-mile distribution system that is part of a network of eight interstate pipelines. We purchase gas during the summer months when it is normally less expensive and store it for use throughout the year. This helps keep winter costs down and our year-round supply up. Our gas purchasing strategies, coupled with our underground storage facilities, ensure that Nicor Gas customers receive reliable, competitively-priced service.
