Economic Studies

How did you estimate the economic benefits?

We estimated economic impacts using established economic modeling methods. The Jobs and Economic Development Impact ("JEDI") model, developed by the U.S. Department of Energy, was used to calculate the direct and indirect economic impacts of the construction and ongoing operations of the wind farms that will be built as a result of our transmission line. IMPLAN, a widely-used input-output economic impact model, was used to estimate the direct and indirect economic impacts triggered by the construction and ongoing operations of the Rock Island Clean Line.

We have also engaged professors at the University of Iowa and Illinois State University to conduct a more extensive study of the economic impacts associated with the development, construction, and operation of our transmission line. The report, authored by Dr. Lon Carlson, Dr. Dave Loomis and Dr. John Solow, summarizes the estimated economic impacts of the Rock Island Clean Line, including the impacts of the construction and operation of the transmission line and the production of inputs to the line—towers, wire, real estate services—and the impacts of the construction and operation of the wind farms this transmission line would enable.

Dr. Loomis is Professor of Economics, Director of the Center for Renewable Energy, and Executive Director of the Institute for Regulatory Policy Studies at Illinois State University. Dr. John Solow is an Associate Professor of Economics at the Tippie College of Business at the University of Iowa. Dr. Lon Carlson is an independent consultant recently retired as an Associate Professor in the Department of Economics at Illinois State University and Director of Outreach for the Institute of Regulatory Policy Studies.
