Illinois Rivers transmission project receives final approval

The Illinois Commerce Commission awarded Ameren Transmission Co. of Illinois (ATXI) final route approval for a 400-mile-long transmission project along the Illinois River.

Ameren Transmission Co. of Illinois (ATXI), a unit of Ameren Corp. (NYSE: AEE), will build the 345,000-volt transmission line, which will run from Palmyra, Mo., crossing the Mississippi River at Quincy.

The estimated $1.1 billion project will then run east past Meredosia, Pawnee, Pana, Mt. Zion and Kansas, ending at Sugar Creek, Ind., with additional lines running from Meredosia to Ipava and between the Sidney and Rising substations near Champaign.

Substation construction is underway. Line construction is expected to commence later in 2014.

The new transmission lines and substations will result in lower power prices and improve reliability and efficiency to the power grid.

The project previously received approvals from the Federal Energy Regulatory Commission (FERC) and the Midcontinent Independent System Operator Inc. (MISO).
