On November 25th, 2014, the Illinois Commerce Commission (ICC) unanimously approved an Order granting Rock Island Clean Line a Certificate of Public Convenience and Necessity to construct and operate the Illinois portion of a new 500-mile direct current electric power line. The Rock Island Clean Line will deliver 3,500 megawatts of low-cost wind power from the greater northwest Iowa area to Illinois.

Rock Island Clean Line filed petitions with the Iowa Utilities Board (IUB) for electric transmission line franchises.  These franchise petitions request approval to erect, maintain and operate an electric transmission line in 16 Iowa counties. In its petitions to the IUB, Rock Island formally requested approval of a route for the line.

Please note that an identical document was filed in each of the 16 counties. In the fall of 2013, Rock Island held informational meetings in all 16 counties through which the proposed route crosses.

Approved: May 2012

In November 2011, Clean Line Energy filed an application with the Federal Energy Regulatory Commission (FERC) seeking authority to negotiate rates and enter into contracts with customers for the project. The application can be found on the Federal Energy Regulatory Commission's website here. On May 22, 2012, our application was approved by FERC.  Receiving this authority will allow Clean Line Energy to begin negotiations with potential customers, likely load serving entities or wind developers. View FERC's approval.
