Ameren Missouri is expanding its efforts to bolster reliability in downtown Jefferson City. The company is installing new smart technology to support critical government services. The new equipment builds on the success of the Jefferson City Smart Grid Project, one of Ameren Missouri’s first projects under the Smart Energy Plan.

The initial build-out of the Smart Grid in 2019 included the addition of eight smart switchgear in downtown Jefferson City. This latest upgrade will add four more switchgear to the grid. These devices work together to monitor the system, detect and isolate outages, and quickly re-route and restore power.

“The people who live and work in Jefferson City were the first in Missouri to experience the advantages of a smart grid system,” said Jason Haynam, senior manager of Ameren Missouri’s central Missouri division. “Now, with nearly 2,000 smart devices installed across the state, we’re seeing the power of this innovative technology benefit customers across our service territory.”

Smart devices have prevented more than 330,000 customer outages across the state since Ameren Missouri began installing them through the Smart Energy Plan. In addition to the downtown grid, there are now dozens of smart switches on overhead power lines throughout Jefferson City.

One of the newly installed switchgear will support the Jefferson State Office Building, which is undergoing a major renovation to modernize the 70-year-old building. It houses state agencies such as the Department of Education. An additional smart device will be installed in a later phase of the project. Two additional smart devices will support the Truman State Office Building, which houses the Office of Administration and the Missouri Department of Revenue.

“Reliability is so important, especially in the workplace. Millions of Missourians rely on the critical services provided by state agencies, and we rely on Ameren to keep the power on,” said Rep. Dave Griffith of Jefferson City. “It’s a comfort to know this expanded smart grid will help ensure there is minimal disruption to our operations and allow us to meet the needs of those we serve.”
