Open houses scheduled in Missouri for Mark Twain Transmission Project

Open houses on the Mark Twain Transmission Project will be held this month, beginning on June 13 in Palmyra, Mo., Ameren (NYSE: AEE) said on June 5.

As TransmissionHub reported in May, Ameren Transmission Company of Illinois (ATXI), in collaboration with Northeast Missouri Electric Power Cooperative (Northeast Power) and Ameren Missouri, have proposed a new route for the Mark Twain Transmission Project that would use the existing right of way (ROW) of Northeast Power and Ameren Missouri. The proposed new route would minimize impact to landowners, communities, and existing farmland, Ameren added in a May 2 statement, noting that the new route would result in fewer utility structures along the existing ROW.

ATXI, Northeast Power, and Ameren Missouri are requesting input from landowners on the new, approximately 100-mile route for the 345-kV transmission line, Ameren said in its June 5 statement, noting that the project, to be built in northeast Missouri, also involves a substation.

The proposed route would run through Adair, Knox, Lewis, Marion, and Schuyler counties, Ameren said, adding that the route would use more than 90% of existing ROW on Northeast Power’s 161-kV line between Palmyra and Kirksville and Ameren Missouri’s 161-kV line from Kirksville to the Iowa border.

Other open houses are scheduled for June 14 in Edina, Mo., June 15 in Kirksville, Mo., and June 16 in Queen City, Mo., the company said.

After recent discussions with the Adair County Commission, commissioners asked ATXI to consider reconfiguring a portion of the route that runs through Adair County, and as a result, ATXI and Northeast Power are seeking input on three new route options in the area south of Kirksville, Ameren said. Adair County’s suggestion to move the proposed location of the new substation is also being considered, the company said.

According to the project’s webpage, project benefits include improved electric system reliability; improved access to renewable energy sources; and improved transmission capacity. 

Ameren said in its statement that ATXI expects to invest about $250m on the project, which is planned to be in service in December 2019.
