Natural Gas Rate Update - Residential - Illinois - Liberty

Illinois Natural Gas Rate Request Information

On December 20, 2023, Liberty submitted a request with the Illinois Commerce Commission (ICC) to adjust natural gas base rates. The ICC has assigned the matter Docket Number 24-0043.

The last base rate update for Illinois natural gas customers was effective in June 2017. Customers also saw a bill decrease in March 2018, due to an income tax decrease (ICC Docket Number 18-0197). Over the last six years, Liberty has invested approximately $34 million in Illinois to support initiatives that benefit its natural gas customers, strengthening the reliability and resiliency of its system.

If approved by regulators, the rate adjustment for Liberty’s investments would cost the average Liberty Illinois residential gas customer approximately $15.82 per month, or 18.4% of the total bill, based on approximately 60 Ccf of usage per month.

The rate request process can take up to 11 months as the ICC and other stakeholders carefully review Liberty’s request. If approved, new rates would go into effect in December 2024.


Key investments to benefit customers included in the rate update request:

Since the last base rate adjustment in 2017, Liberty has made critical Investments in the natural gas distribution system to ensure the ongoing delivery of safe, reliable energy for its customers. This includes:

  • Updating and replacing aged pipeline infrastructure with modern polyethylene. Polyethylene piping is lighter and more durable than its steel counterparts and able to withstand high pressures and temperatures. The new infrastructure is easier and faster to locate during an emergency and less susceptible to leaks.
  • Installing and implementing Automated Meter Reading (AMR) to allow Liberty to read meters without having to access a customer’s property. This technology improves service and operational efficiency. It allows Liberty to gather meter readings safely and efficiently, plus it helps to reduce the need to estimate meter readings.
  • Improving the customer experience through modern service platforms. Customers now have access to a new online account platform that includes a mobile app, making their service simpler and more convenient. Customers can choose to view bills, make payments, monitor their usage, and receive text and email alerts about payments and services.
  • Installing compressed natural gas (CNG) filling stations at Liberty service center locations in Harrisburg, Girard, and Vandalia. Using CNG helps Liberty reduce fuel costs for its vehicles over time - savings that can be passed on to customers through lower operating costs, It's also a cleaner burning fuel, which reduces pollution, helping to protect the environment through cleaner air.
  • Relocating our Metropolis service center to a larger, safer, and more modern facility. The new service center provides needed space for adequate storage for equipment and materials and allows Liberty to consolidate and streamline business processes in a more secure and accessible location for our employees.
