Ameren completes, energizes Mark Twain Transmission Project

Ameren Corporation announced yesterday that Ameren Transmission Company of Illinois completed and energized the Mark Twain Transmission Project in Missouri.

The project includes the Zachary substation in Adair County, Mo., and a 96-mile, 345,000-volt transmission line that travels west from Palmyra to Kirksville, Mo., then north to the Iowa border.

“The Mark Twain Transmission Project benefits are many,” Shawn E. Schukar, chairman and president of ATXI, said. “In addition to making the energy grid more reliable and promoting renewable and affordable energy such as wind, it will meet energy needs not only for today but well into the future.”

Ameren Corporation noted that the project will enable enhanced grid reliability, increased transmission capacity, and improved access to lower-cost energy, including from wind projects. The $267 million project entered service on Dec. 19.

“The speed and efficiency with which this line was developed and constructed can be attributed to the ongoing collaboration and strong communication efforts we had with landowners, community representatives, and Northeast Missouri Electric Power Cooperative,” Schukar said. “Because of our focus on communication, our contract partners were able to quickly move forward on key construction phases, meet crucial deadlines, and now energize this important infrastructure project that bolsters the energy grid.”
