Ameren: ATXI completed $1.4bn Illinois Rivers Project in December 2020

Ameren said that other ATXI MVPs include the Spoon River Project in Illinois, which was completed in February 2018, and the Mark Twain Transmission Project, which went into service in northeast Missouri in December 2019

Ameren on Jan. 6 said that its wholly owned subsidiary, Ameren Transmission Company of Illinois (ATXI), in late December 2020 completed and energized the final span of the $1.4bn, 375-mile, 345-kV Illinois Rivers Project transmission line from Palmyra, Mo., to Sugar Creek, Ind.

As noted on the project’s webpage, four towers are required for the river crossing, with two on the east side and two on the west side of the Illinois River.

The company noted in its statement that the Midcontinent ISO (MISO) in 2011 approved the project, which is part of a coordinated, multi-state group of transmission projects, known as the Multi-Value Projects (MVPs), that is being developed by transmission owners in the Midwest to strengthen the regional energy grid, as well as to facilitate the integration of renewable energy to meet public policy goals.

Ameren said that other ATXI MVPs include the Spoon River Project in Illinois, which was completed in February 2018, and the Mark Twain Transmission Project, which went into service in northeast Missouri in December 2019.

As TransmissionHub reported, Ameren in early January 2020 said that ATXI completed and energized the $267m, 345-kV Mark Twain project, which involves a substation and a 96-mile transmission line that travels west from Palmyra to Kirksville, Mo., then north to the Iowa border.

The project, which includes the Zachary substation in Adair County, Mo., was placed into service as expected on Dec. 19, 2019, the company said.

As noted on the project’s webpage, the line’s route runs through Adair, Knox, Lewis, Marion, and Schuyler counties in Missouri. Nearly 100% of the line is co-located on existing rights of way, the site noted, adding that the route will co-locate on existing right of way (ROW) on Northeast Missouri Electric Power Cooperative’s 161-kV line between Palmyra and Kirksville and Ameren Missouri’s 161-kV line from Kirksville to the Iowa border.

According to the Spoon River project webpage, that project involves a 44-mile, 345-kV line between Galesburg and Peoria.
