Ameren Transmission Company of Illinois (ATXI) has completed and energized the Illinois Rivers Project, a 375-mile, 345,000-volt transmission line from Palmyra, Missouri, to Sugar Creek, Indiana.
The final span of the project was placed into service in late December.
The Illinois Rivers Project was approved in 2011 by the Midcontinent Independent System Operator Inc. (MISO). The project is part of a coordinated, multi-state group of transmission projects in the Midwest to strengthen the regional energy grid and to facilitate the integration of renewable energy to meet public policy goals.
According to a press release, the $1.4 billion project aims to provide improved energy grid reliability, increased transmission capacity, access to lower-cost energy and electricity from renewable sources for Midwestern families and businesses.
The project is ATXI’s third completed Multi-Value Project. Others include the Spoon River Project in Illinois, which was completed in February 2018, and the Mark Twain Transmission Project, which went into service in Northeast Missouri in December 2019.
“Our country’s future energy security and sustainability depends on a strong transmission system to enable the transition from coal to renewable energy,” said Shawn Schukar, chairman and president of ATXI.
Ameren Transmission Company of Illinois is a wholly owned subsidiary of Ameren Corporation dedicated to electric transmission infrastructure investments.
