Ameren unit energizes 345-kV Spoon River transmission line in Illinois

Ameren Transmission Co. of Illinois has placed into service its 345-kV Spoon River transmission project nine months ahead of schedule.

The project cost $130 million and includes a transmission line that runs 44 miles between Galesburg and Peoria in Illinois and two new substations. It is intended to strengthen the reliability of the grid and provide greater access to renewable energy sources, the Ameren Corp. subsidiary said in a Feb. 22 news release.

Ameren Transmission said the project also supports Illinois' goal of having 25% of its energy generation come from renewable sources by 2025 to 2026.

The project is one of the company's three projects designated by the regional grid operator the Midcontinent ISO as "multivalue projects" that will improve and strengthen the regional grid. The other two projects are currently underway in Illinois and Missouri.
