Supporting reliability in North St. Louis County

Ameren Missouri's Smart Energy Plan aims to harden area's electric grid, supporting reliability and resiliency

Through its Smart Energy Plan, Ameren Missouri is storm-hardening more than two miles of distribution lines in Spanish Lake, supporting increased reliability for over 1,400 customers, including critical facilities such as Christian Hospital. As part of the project, the company has strategically installed composite power poles. These hardened fiberglass poles are stronger than traditional wooden poles and work to anchor the system during periods of severe weather or an outage— preventing cascading damage and often speeding restoration times.

In addition to the storm-hardening upgrades in the community, Ameren Missouri installed smart switch technology throughout the area, providing rapid outage detection and automatic restoration, reducing both the size and duration of potential outages. The project also included the removal of overhead powerlines across Highway 367 and burying them underground.

Additionally, Ameren Missouri has made several other improvements throughout Spanish Lake. In 2023, crews replaced aging substation equipment serving the community. In 2025, the company upgraded more than a mile of overhead power lines along Riverview Drive. These two projects will serve as critical service backups for the new St. Louis Zoo Wildcare Park under development in Spanish Lake.
