Overview

The Rock Island Clean Line is a 500-mile overhead high voltage direct current (HVDC) transmission line that will deliver 3,500 megawatts from northwest Iowa and the surrounding region to communities in Illinois and other states to the east, areas that have a strong demand for clean, reliable energy. The name of the project comes from the Rock Island Railroad, which stretches across the entire state of Iowa, through the city of Rock Island and into Illinois.  Just as the Rock Island Railroad allowed farmers to move their goods to market, the Rock Island Clean Line will deliver clean, renewable energy to the communities that need it, representing the new farm to market model for the 21st century.
