Clean Line files route, raises cost estimate for Grain Belt Express

Clean Line Energy Partners increased the cost estimate for the Grain Belt Express project by $500m to $2.2bn, President and CEO Michael Skelly said in testimony provided to the Kansas Corporation Commission (KCC).

The company on July 15 filed with the KCC a siting permit application for the transmission project.

In addition to the cost increase, Skelly said the line will now deliver electricity to the PJM Interconnection, in addition to the Midcontinent ISO (MISO).

In its application, Clean Line requested a siting permit authorizing it to construct 370 miles of the total 750-mile project, beginning in Ford County, Kan., to the Kansas-Missouri border; a converter station in Ford County, Kan.; and facilities to interconnect the converter station with the Southwest Power Pool.

The DC facilities in Kansas are estimated to cost $900m, an increase from $896m.

Grain Belt Express is a 600-kV HVDC line will run from near the Spearville 345-kV substation in Ford County, Kan., to a location at or near Ameren’s (NYSE:AEE) Palmyra Tap 345-kV substation in Missouri and then to Indiana Michigan Power Company’s 765-kV Sullivan substation in Sullivan County, Ind.

The KCC on Dec. 7, 2011, granted Clean Line permission to operate as a utility in the state. The Indiana commission granted the company utility status in that state on May 23.

The company will file a line siting application for the AC collector system, after wind generators that will connect to the project are identified, according to the application. 

Grain Belt Express will use lattice and monopole towers between 100 ft. and 175 ft. tall. Right-of-way will be between 150 ft. and 200 ft. wide. 

Construction is scheduled to begin in 2016, with completion in 2018.
