Rock Island Clean Line is a 500-mile, 600-kV transmission line that originates at Central Illinois and terminates at Northwest Iowa. The project will span the entire state of Iowa bringing renewable energy from areas in South Dakota, Minnesota, Iowa and Nebraska to load center in the midwest. The project involves more than 500 miles of HVDC circuit and is expected to enable more than 3,500 MW of renewable energy to the region. It will improve reliability and reduce line congestion along it’s path. The Rock Island Clean Line is estimated to provide more than 5,000 construction jobs and more than 500 permanent jobs to maintain and operate the wind farms and the transmission line. The project will make possible more than $7 billion of new renewable energy projects. The new investment will result in a significant increase in property tax revenues, landowner royalty payments and direct economic benefit to rural communities. The project’s future is uncertain after repeated approval problems with regulators in Iowa.
