Replacing 106 MW Coal with 106 MW BESS; Edwards Unit 3 (MISO-R1055) is a proposed battery energy storage development project in Peoria County, Illinois. The queue lists it as a hybrid project with a total capacity of 322 MW, classified under "Other" and "Battery" technology categories. Its single listed component is 322 MW categorized as "Other." The project name refers to replacing 106 MW of coal-fired capacity with 106 MW of battery energy storage at Edwards Unit 3. The project would connect at the E.D. Edwards 138kV point of interconnection within the Ameren Illinois utility service territory.
The project is in the Midcontinent Independent System Operator (MISO) interconnection queue, which it entered on July 12, 2024, and its status is currently active. It has requested Network Resource Interconnection Service (NRIS). The proposed commercial operation date is September 30, 2025. The available data does not indicate the status of an interconnection agreement, identify a developer, or note any news coverage of the project.
