Sargent & Lundy LLC has been selected to provide engineering and design services for the 345 kV Brookings County-Hampton Transmission Line project, which is part of the CapX2020 project, a series of high-voltage transmission lines intended to improve electric-service reliability in Minnesota and the surrounding region.
The Brookings line extends approximately 240 miles from the Brookings County Substation in eastern South Dakota to the Hampton substation southeast of Minneapolis.
The project is expected to improve reliability throughout southwest and west central Minnesota and the Twin Cities, as well as enable access to new generation, including renewable energy resources in the area.
Sargent & Lundy's scope of work will include the finalization of the project-specific design criteria, complete detailed design of the line, foundation design, and support for material procurement. The transmission line will be constructed using tubular steel poles with double-circuit capabilities.
Sargent & Lundy will work closely with Great River Energy and the CapX2020 Project Management Office to execute the work.
Construction is scheduled to begin in 2012 and be completed in 2015. The construction schedule is dependent upon the certainty of cost allocation by the Midwest Independent Transmission System Operator and completion of commercial arrangements by the CapX2020 utilities.
