Illinois Commerce Commission approves Grain Belt Express transmission line

On Thursday, the Illinois Commerce Commission (ICC) approved Grain Belt Express Clean Line LLC’s application for a certificate of public convenience and necessity to construct, operate and maintain a 600 kV, 4,000 MW capacity, high voltage electric transmission line.

The 780-mile Grain Belt Express Clean Line transmission line will span from Kansas to Indiana. The proposed line spans much of south-central Illinois, including right-of-way in Pike, Scott, Greene, Macoupin, Montgomery, Christian, Shelby, Cumberland, and Clark Counties. The project will provide direct access for high capacity wind generation to the electricity markets.

The ICC’s order requires that Grain Belt Clean Line secure funds to cover total project costs before construction commences, prohibits project expansion without Commission approval, and requires further Commission approval prior to recovery of any project costs from Illinois retail ratepayers through regional cost allocation. The ICC also directed Grain Belt Clean Line to take specific actions to address landowner concerns that included potential impacts from the construction of the line on irrigation operations, soil compaction and erosion, wetland areas, and timber land.

All documents related to the case, including the Commission’s Final Order, can be viewed under docket number 15-0277 via the ICC’s e-docket system at www.icc.illinois.gov.
