A $5.3bn smart energy plan to modernise the US state of Missouri’s energy grid has been unveiled.


The plan includes more than 2,000 electric projects over the next five years to provide customers with a smarter grid and cleaner, more reliable energy.


Major infrastructure project


The upgrade plan to be delivered by utility Ameren Missouri will be the largest infrastructure undertaking in the company’s history.


“Building a smart grid for the future of energy in Missouri is foundational to our mission to power the quality of life for our customers and the communities we serve for generations to come,” said Michael Moehn, president of Ameren Missouri.


“We have developed a forward-thinking and customer-focused infrastructure upgrade plan that will not only produce a grid that is more reliable and resilient, but also be able to accommodate more renewable energy.”


Upgrades in reliability, resilience and service throughout the energy company’s 24,000-square-mile service territory are the foundation of the plan. This includes:

  • More than 2,000 infrastructure improvement projects across the state totalling $5bn in capital investments over the next five years, including approximately $1bn in electric investments in 2019
  • Major renewable energy projects to continue the transition to a cleaner energy future for customers, including $1bn for wind energy in 2020. This also includes modernising the energy grid to allow Ameren Missouri to add more solar energy and battery storage on the system to cost-effectively boost reliability, particularly in rural areas
  • New smart grid sensors, switches and self-healing equipment to rapidly detect and isolate outages – reducing the number of outages and speeding power restoration when service interruptions occur
  • A stronger, more secure energy delivery backbone including installing 12,000 new utility poles for storm hardening, many fortified with composite materials to better withstand severe weather
    More than 400 miles of new underground cable and equipment to create a more efficient and reliable underground energy delivery system that better serves customers
  • More than 70 new or upgraded substations to increase energy service reliability and serve more customers through a streamlined network that is more cost-effective and efficient
  • Adding more than 800,000 smart electric meters through 2023 to give customers more insight and control of their energy options and costs.

“Our customer-focused plan supports Ameren Missouri’s vision to lead the way to a secure energy future, making our state an even better place to live and do business,” Moehn added.


Ameren Missouri’s service area covers 64 counties and more than 500 communities, including the greater St Louis area of Missouri.
