Green Power Express is a 3045-mile line, 765-kV transmission line originating at Madison, Wis., and terminating at Antelope Valley, N.D. The project, proposed by ITC Holdings Corp., would facilitate movement of 12,000 MW of energy from wind rich areas in Iowa, Minnesota, and North and South Dakota. The transmission project, which is estimated to cost between $10 and $12 billion, will traverse portions of North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, Illinois, and likely into Indiana. The project addresses the recognized lack of electric transmission infrastructure needed to integrate renewable wind energy. According to ITC’s 2012 Form 730 filing with FERC, project spending is estimated to run about $519 million between 2013 and 2016. In April 2009, FERC approved transmission-investment incentives for the project, saying it would provide benefits such as improved transfer capability and access to wind power generation. According to ITC’s project FAQ page, MISO recently unveiled its Multi-Value Project Portfolio (“MVP Portfolio”). This collection of high-voltage projects in part represents a more concrete version of segments of the Green Power Express. While MISO has chosen to utilize 345kV instead of 765kV, the MVP Portfolio follows similar electrical paths and begins to accomplish the same purposes as the Green Power Express. ITC envisions that future MVP projects will ultimately complete a high voltage network functionally equivalent to the Green Power Express proposal.
