Ensuring affordable and resilient energy infrastructure
As Illinois experiences growth and transformation in the energy landscape our commitment to serving 2.3 million customers remains steadfast. Nicor Gas has filed a request with the Illinois Commerce Commission (ICC) to increase rates, which will enable us to continue investing in resilient energy infrastructure, while also complying with state and federal safety standards. These efforts will enhance our ability to safely, reliably and affordably meet both current and future demands.

Investing in a reliable and sustainable energy future
Nicor Gas’ natural gas system provides dependable, resilient and affordable energy to customers when they need it, even on the coldest winter days. As Illinois’ largest natural gas provider, we continue to deliver the clean, safe, reliable and affordable natural gas service that our customers expect and deserve.
On Jan. 9, Nicor Gas filed a proposed request of approximately $221 million with the ICC, which has 11 months to review.* If approved, the adjusted rates will allow the company to continue making strategic investments to help enhance the safety, reliability and resilience of its natural gas system, especially during extreme weather, while also complying with state and federal safety standards.
With this proposed request, a typical residential customer would see an increase of less than $6 per month in their energy delivery charge, or 6.7% annual increase. Even with the proposed new rates, Nicor Gas’ distribution rates remain among the lowest of any major natural gas distribution company in Illinois and significantly lower than other fuel alternatives.
All utilities, including Nicor Gas, must submit rate requests to the ICC for approval.
Some proposed key upgrades and infrastructure enhancements
- Replacement of aging equipment and maintenance of storage facilities.
- Safety-related replacement of over 45 miles of distribution pipeline, as recommended by the U.S. Pipeline and Hazardous Materials Safety Administration.
- Relocation of natural gas facilities in coordination with state and local agencies, to accommodate public infrastructure improvements.
- Inspection, assessment and repair of over 400 miles of transmission pipeline to help ensure the continued safe and reliable delivery of natural gas in compliance with federal regulations.
*Throughout the 11-month period, multiple parties evaluate the proposal, and the proposed figures may be revised before the ICC reaches a final decision.
What is a Rate Request?
Rate requests are formal proceedings directed by state utility commissions used to address the costs of operating and maintaining the utility system. Illinois’ investor-owned utilities must file a general rate case petition with the ICC to determine the total amount the utility is authorized to collect in customer rates and for what share of those costs each customer class is responsible. These proceedings take 11 months and allow for stakeholder participation and public comments.
What is the ICC's Role?
The Illinois Commerce Commission (ICC), composed of appointed Commissioners, legal counsel and support staff, is responsible for regulating the state’s public utilities to ensure adequate, efficient, reliable, safe and least-cost public utility services. The ICC thoroughly evaluates rate requests to balance the interests of consumers and utilities.
