345 kV Underground Report

The underground report conducted by Power Engineers, Inc. examined the cost estimates to install an alternative 345 kV underground transmission line for the CapX2020 Fargo-St Cloud 345 kV project. It also compares environmental impacts of overhead and underground transmission line construction. The study was released in February 2010.

Agricultural impact mitigation

Developed with the Minnesota Department of Agriculture, the agricultural impact mitigation plan describes the process in which the CapX2020 utilities will minimize impacts to agricultural land during the construction process. It was released in June 2009.

WIRES 2016 Brattle Report

Manitoba Hydro Transmission Expansion Studies
Several studies have been conducted detailing issues related to transmission needs to increase the amount of electricity from hydro-power resources in Canada. Links to the studies are available here.

Industry report: Up to 200,000 full-time jobs could be created annually over two decades by expanding the transmission grid
This WIRES report, as estimated by the Brattle Group, examines the long-term transmission investment needs and associated employment, economic stimulus and other benefits in the United States and Canada. The report was released in May 2011.

Smart transmission: Modernizing the nation's high voltage electric transmission system
This WIRES report examines the emerging "smart grid," focusing on how modern technology addresses operational challenges confronting the North American bulk power system. It also describes innovations that are being installed within the transmission network. The report was released in January 2011.

Economic impact study
The economic impact study, conducted by the University of Minnesota Duluth's Bureau of Business and Economic Research, estimates the CapX2020 projects will result in the creation of thousands of construction and related jobs as well as collectively provide nearly $50 million in tax revenue to the four states in which the projects will be built. It was released in November 2010.

Dispersed renewable generation studies
Dispersed renewable generation studies were required as part of the Next Generation Act of 2007. Phase One was completed in June 2008; Phase Two was completed in September 2009. The studies are available on the Minnesota Department of Commerce CARDS website. Select "Energy Data and Reports" as the area of interest, then select "Dispersed Renewable Generation" as the topic.
 
Communited-based Energy Development
The Minnesota Department of Commerce is interested in promoting Community-based Energy Development (C-BED) projects in Minnesota. The department encouraged utilities to undertake a study to determine how C-BED projects can be interconnected to the transmission system. The CapX2020 C-BED Interim Report was released in June 2006. The final CapX2020 C-BED Transmission Study Report was released in January 2007.
