Improving reliability in St. Charles and Warren counties

Smart Energy Plan upgrades impact more than 2,500 customers in the region

A new substation in Foristell, Missouri, is now delivering reliable power to the people of St. Charles and Warren counties. This substation and other new upgrades to the area are part of Ameren Missouri's efforts to modernize the electric grid through the company's Smart Energy Plan.

Located on Veterans Memorial Parkway at Route T, the new substation serves approximately 2,700 customers between Wright City and Wentzville and is equipped with smart technology to help automatically detect outages and quickly reroute power. Additionally, the substation increases the area's electric capacity, allowing for future growth throughout the community. The project also includes upgrades to a nearby bulk substation and 10 miles of new wires and poles serving Wright City to the west and parts of Wentzville to the east. Some of the new poles are made of composite material, designed to better withstand high winds and other hazards, making the lines more resilient and reliable.

In addition, the project continues Ameren Missouri's commitment to using in-state suppliers through the Smart Energy Plan. Avail Switchgear Systems of Fulton, Missouri, manufactured four switchgears installed at the site. WEG Transformers USA built the substation’s two new transformers at its facility in Washington, Missouri.

The Smart Energy Plan was enabled by the Missouri Legislature's passage of Senate Bill 564 in 2018 and approved for extension and expansion by the General Assembly in 2022. Through the Smart Energy Plan, Ameren Missouri is working to upgrade and modernize the electrical grid while improving reliability throughout its service territory.
