Keeping Gas Prices Down
Nicor Gas customers are connected to an approximately 33,000-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.
Our corporate office is in Naperville, Illinois, with regional offices located throughout our service territory.
