Ameren Illinois Upgrading Natural Gas Infrastructure In Peoria

Company upgrading pipeline ahead of hydrostatic pressure test

PEORIA (APRIL 16, 2024) – Ameren Illinois customers driving in and around North University Street and Illinois Route 40 in Peoria will see energy at work now and throughout August as the company upgrades a major natural gas transmission pipeline ahead of a hydrostatic pressure test of the pipeline.

Work recently began along a seven-mile section of existing natural gas pipeline from North University Street and Willow Knolls to East Boy Scout Road in Mossville. Ameren is working with IDOT and the City of Peoria to control traffic near the construction area.

Weather permitting, this portion of the project should be completed by mid-May. Upgrades along the route include:

  • North University Street: natural gas regulator station improvements
  • North University Street and Pioneer Parkway: fitting replacements
  • North University Street: new gas regulator station installation at the Ameren operating center
  • Mount Hawley Airport: re-route and valve installation
  • Route 40 and Ravinwoods: valve replacements at

Once these upgrades are completed, Ameren will inspect the seven-mile section of pipeline before conducting a hydrostatic pressure test in August.

"These proactive steps will ensure the continued safe, reliable delivery of natural gas today while preparing us to meet the future needs of our natural gas customers," said Andrea Parker, Director of Gas Operations. "Many customers think of Ameren Illinois as an electric company, but we also provide safe reliable natural gas service to Peoria. We have full-time natural gas professionals who live and work in the Peoria area who maintain the system; respond to gas leaks free of charge, 24/7, install new services, and perform construction projects."

"We need everyone's help when it comes to work zone safety in these neighborhoods and on every route where workers are present," said Karen Boulanger, Director of Safety for Ameren Illinois. "The signs and cones create their protected work area. Please slow down as you drive on these local streets and pay attention. Our co-workers want to return home safely at the end of the day."

Safe Digging

As required by law, Ameren Illinois will call J.U.L.I.E. (8-1-1) prior to starting work so crews can dig safely. Customers will see paint marks and colored flags near the work area and along the road to mark the location of underground utilities.
