Mark Twain Transmission Project 
Ameren Transmission Company of Illinois (ATXI) is planning to build a 345,000 volt transmission line in northeast Missouri, along with a 345,000 volt substation near Kirksville. Known as the Mark Twain Transmission Project, it consists of two line segments, from Palmyra to Kirksville, and Kirksville to the Iowa border, totaling approximately 100 miles.

The project is part of improvements to the regional transmission "grid" that were approved by the Midcontinent Independent System Operator (MISO) in 2011 and are known as Multi-Value Projects (MVP). MVPs like Mark Twain benefit Missouri and the region by improving the efficiency of the regional transmission system, increasing access to lower cost energy sources, including renewable resources like wind energy, and improving overall transmission system reliability. Local economies will benefit from the new construction jobs and investment. (See project fact sheet.)
The Mark Twain Transmission Project will provide regional and local benefits, including:
Reduced congestion and improved efficiency of the regional transmission grid
Better access to sources of renewable energy
Improved electric transmission system reliability
New construction jobs and associated revenue for the region
ATXI will be developing the Mark Twain Transmission Project in collaboration with landowners, community officials, and agencies by incorporating their input during the evaluation of constructible route options. Some of the routing criteria that will be reviewed will include, but will not be limited to, the items below (not in order of importance):
Agricultural lands   Recreational areas
Airports   Residences
Cemeteries   Schools
Conservation areas   Wetlands & streams
Cultural resources      
Engineering &
construction considerations
