Smart Energy Plan project boosts reliability and supports recovery in North St. Louis

Smart technology and storm-hardening upgrades designed to help reduce outages and restore power faster when disruptions occur

Ameren Missouri recently completed construction of a new electric substation in North St. Louis. The new substation is part of a Smart Energy Plan project designed to strengthen service for customers while supporting storm recovery efforts in a community still rebuilding after the May 16 tornado.

Crews work to set equipment at the new substation in North St. Louis.

"These upgrades represent an investment not only in infrastructure but also in the long-term success of St. Louis," said Landy Wince, senior director of division operations for Ameren Missouri. "This project serves as a prime example of how reliable power can be a catalyst for community development and supports our customers when severe weather threatens."

Beyond improved reliability, the new substation reflects Ameren Missouri's broader commitment to collaboration and community partnership. The company worked closely with the City of St. Louis, local leaders and community organizations throughout the project, reinforcing a shared goal of strengthening critical infrastructure while supporting neighborhood vitality.

"This project shows us what can happen when our local utilities listen to the people they serve and we work together on outcomes that directly benefit the community," said Ward 10 Alderwoman Shameem Clark Hubbard. "Reliable power is a critical piece of the ongoing tornado recovery and neighborhood rebuilding efforts, and I'm pleased to know my constituents have that support from Ameren Missouri through improvements such as this."

The new substation is part of Ameren Missouri's Smart Energy Plan, a multi-year effort to improve reliability, enhance storm resilience and modernize the electric grid to better serve customers across the state. The project delivers multiple benefits for the St. Louis region:

• Meets the growing energy needs of Delmar DivINe and fleet electrification at the Metro Transit DeBaliviere bus garage.

• Reduces demand on two substations nearby, supporting increased reliability for about 8,000 customers in the immediate area.

• Utilizes smart technology that rapidly detects outages and automatically restores power.

• Includes storm-hardening upgrades to support greater resilience during severe weather and faster restoration if damage does occur.

• Uses Missouri-made equipment, such as the substation transformer manufactured in Washington, Missouri, by WEG Transformers USA.
