Edwardsville Reliability Enhancement Project

Modernizing natural gas delivery in the Edwardsville area

To meet the needs of our customers while strengthening the safety, integrity and reliability of our region's natural gas system, in 2027, Ameren Illinois plans to construct an energy project that will modernize natural gas delivery in the greater Edwardsville area.

This natural gas infrastructure project, known as the Edwardsville Reliability Enhancement Project (Project), will evaluate the opportunity to repurpose and enhance the existing gas infrastructure. Ameren Illinois will propose a route for, and design and construct, a new gas transmission pipeline with the goal of minimizing the impact on the community and the environment.

For more information, please view our Project Factsheet (PDF).

Frequently Asked Questions

The purpose of the Edwardsville Reliability Enhancement Project is to modernize and strengthen the safety, integrity and reliability of Ameren Illinois’ natural gas system, and to enhance operation flexibility to meet our customer’s needs.

As part of Ameren Illinois' efforts to comply with the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) regulations and to modernize its natural gas system, Ameren Illinois is evaluating the opportunity to repurpose the existing below ground and above ground facilities. Ameren Illinois may re-utilize and repurpose some existing infrastructure starting south of where the Ameren Illinois Pipeline crosses I-270 and ends at the Franklin St. Station at the intersection of Franklin Ave. and Madison Ave. Ameren Illinois will also propose a route for, and design and construct, a new gas transmission pipeline. The final length of the Project will be determined based upon the routing study and selection of a final preferred route. 

Infrastructure includes transmission and distribution pipelines, valve stations, above ground regulator stations, and other equipment to operate the natural gas delivery system.
System reliability is the ability of the natural gas system to meet the demand and energy requirements of customers during scheduled and unscheduled outages.
The project area starts south of where Ameren Illinois pipeline crosses I-270 and ends at the Franklin St. Station located at the intersection of Franklin Ave. and Madison Ave. Please refer to the Project map located on this webpage for additional information regarding project locations.
Ameren Illinois will manage the construction process to avoid service interruptions.

A right-of-way easement will give Ameren Illinois the right to use another’s land for a specific, limited purpose. It does not grant ownership of the land to Ameren Illinois. Representatives of Ameren Illinois will contact landowners to negotiate the purchase of an easement so that the pipeline can cross their land.

Ameren Illinois will be requesting a permanent right-of-way easement that is up to 50 feet in width along the length of the new transmission and any associated distribution pipelines. Additional easements will be requested at the pipeline’s origin and terminus points, at any required regulator or valve station locations, and for other Project facilities as required. Additional, temporary right-of-way will be requested for construction purposes.

Yes. Ameren Illinois will host virtual public meetings to present project information to landowners and provide a comment period to better understand their needs and concerns. You can find the date and location of these virtual public meetings on this website.

Our goal is to meet and listen to the residents of the Edwardsville area at every stage of this project. If you would like to speak with a project representative, please feel free to call us at 618.221.0379 or email us at edwardsvillegasproject@ameren.com. 

Ameren Illinois’ continued compliance with evolving regulations will allow for the deployment of advanced technologies to enhance safety and reliability. Ameren Illinois is applying the highest safety standards as it upgrades the natural gas delivery system throughout its 43,700 square-mile territory. The new facilities installed as part of this project will maintain natural gas supply to the Edwardsville area and will continue to allow for efficient and comprehensive inspections of the pipeline.
