Researched by Industrial Info Resources (Sugar Land, Texas)--Ameren Corporation (NYSE:AEE) (St. Louis, Missouri), which currently sources two-thirds of its output from coal and natural gas, is reviving plans to replace generation from its coal-fired power plants that are set to close in the coming years. The midwestern utility also is getting support from state governments for its plans to improve its transmission and distribution (T&D) system. Industrial Info is tracking nearly $1 billion worth of active projects from Ameren and its subsidiaries, more than 70% of which is attributed to T&D projects.

Ameren recently updated the 20-year plan for its Missouri-based subsidiary, where it aims to add 800 megawatts (MW) of gas-fired energy, 4.7 gigawatts (GW) of renewable-sourced energy, and $1.3 billion in battery energy-storage system (BESS) projects by 2036. The company said in early 2021 that it was seeking permits for several proposed solar and BESS projects across Missouri, but these projects had all been cancelled by the fourth quarter of 2022. For more information on Ameren's earlier plans, see March 19, 2021, article - Ameren Sheds Coal for Renewables as it Emerges Stronger from 2020.
The Missouri subsidiary had planned to close its 1,242-MW Rush Island Power Plant in Festus, Missouri, late last year, but reversed course and is now keeping it open into 2024, after the Midcontinent Independent System Operator (MISO) said its closure could lead to outages. Nevertheless, Ameren closed its Meramec Energy Center in Saint Louis, Missouri, in 2022, and it is continuing with plans to close its Sioux Energy Center in West Alton, Missouri, by 2032. Subscribers to Industrial Info's Global Market Intelligence (GMI) Power Project and Plant databases can read detailed profiles on the Rush Island, Meramec and Sioux plants, and click here for a list of ongoing cleanup and remediation projects related to the Meramec and Sioux closures.
MISO is more upbeat about Ameren's T&D projects. The organization recently outlined a potential road map for transmission projects through 2039, and Marty Lyons, the chief executive officer of Ameren, said in a recent earnings-related conference call that detailed project planning, design work and procurement for the first tranche of projects assigned to Ameren is underway.
"We expect construction [on the first tranche] to begin in 2026," Lyons said in the conference call. "Looking ahead to Tranche 2, MISO's analysis of potential projects is well underway and will continue for the remainder of the year and into next year. MISO anticipates the Tranche 2 portfolio of projects will be approved in the first half of 2024. Continued investment in transmission is needed to facilitate the transfer capability of energy across the region as more dispatchable generation retires and renewables come online."
Lyons later added that "it's premature to say exactly how large that [Tranche 2] portfolio will be, or exactly what transmission projects may fall into our service territories in Illinois or Missouri." But Ameren already is at work on the Logan County Connector Project in Illinois, which started construction in March, and it is developing the Limestone Ridge Project in Missouri, which was granted approval last year by the Missouri Public Service Commission.
The nine-mile Logan County line is designed to connect the Limit Substation to the Fogarty Substation both in Lincoln, Illinois, with upgrades to be performed at both facilities. Construction on all three components is expected to wrap up by the end of the year. Subscribers can read detailed project reports on the power line, and the Limit Substation and Fogarty Substation upgrades.
The Limestone Ridge Project comprises two lines and new substations on both ends of each:
