ST. LOUIS - Ameren Transmission Company of Illinois (ATXI) announced it has energized the Zachary Substation and approximately 32 miles of transmission line from Kirksville to the Iowa border, marking a major milestone in the construction process of the 96-mile, 345 kV Mark Twain Transmission Project.

The foundation and line construction crews are now moving their teams to start building the line section between Palmyra and Kirksville which will be completed later this year, the company said in the press statement.

When complete, the project is expected to provide local and regional benefits, including improved energy-grid reliability, increased transmission capacity and greater access to renewable sources such as wind.

ATXI expects to invest $250 million on the Mark Twain Transmission Project. The anticipated in-service date for the 96-mile line is December 2019.
