JEFFERSON CITY, Mo. — The Missouri Public Service Commission (PSC) approved an order for a certificate of convenience and necessity (CCN) to Ameren Transmission Company of Illinois (ATXI) relating to the first phase of transmission investments in North Central Missouri.
Commissioners also approved ATXI to transfer an undivided 49% interest in certain transmission facilities for the Fairport Denny Iowa/Missouri (FDIM) Project to the Missouri Joint Municipal Electric Utility Commission (MJMEUC) shortly before applicable portions of the FDIM Project are placed into service.
The Commission directed ATXI to modify the route for the FDIM Project to address landowner concerns.
The phase one order approves approximately 44 miles of 345 kilovolt (kV) transmission line, in two segments, in Worth, Gentry, and DeKalb counties, and a new 345 kV substation named Denny in DeKalb County, called the FDIM Project – and a separate segment of approximately 9 miles of 345 kV transmission line in Marion County between ATXI’s existing Maywood Substation near Palmyra, Missouri, and the Mississippi River Illinois/Missouri border, including upgrades to the Maywood Substation, referred to as the MaywoodMississippi River Crossing (MMRX) Project.
In July, the Commission authorized phase two of the project for ATXI to construct, install, own, operate, control, manage, and maintain slightly over 200 miles of 345 kV transmission lines across DeKalb, Daviess, Grundy, Sullivan, Adair, Knox, Lewis, Marion, Macon, and Randolph counties – referred to as the DennyZachary-Thomas Hill – Maywood Project, or DZTM Project. Phase two included a letter from Senator Rusty Black, which was co-signed by Senate President Pro Tem Cindy O’Laughlin, Representative Mazzie Christensen, Representative Dean Van Schoiack, and Representative Danny Busick, expressing support for the co-location strategies in the project.
