Biennial Transmission Planning Webcasts

Every two years, Minnesota utilities host webcasts to inform the public about electric transmission needs in the state. Below are links to the presentation delivered on electric transmission planning in Minnesota and electric transmission projects in the West Central Zone. The presentation was delivered via webcast in September 2009.

Canby-Appleton Area

• Canby-Appleton 115-kV line upgrade of an existing 41.6-kV line
• Application for certificate of need and route permit for uprating the existing 41.6-kV line to 115-kV has been submitted to the Minnesota Public Utilities Commission (MN PUC
• Expected construction start date is spring 2007
• Anticipated in-service date is spring 2008

Glenwood Area

• Load serving needs in the area

Hutchinson Area

• Hutchinson – McLeod - Big Swan project built and energized
• McLeod County-Glencoe 115-kV line built and waiting final testing prior to energization
• Suggested Glencoe – West Waconia – Scott County 115-kV line to provide voltage support to both Glencoe and Scott County

St. Cloud- Alexandria Area

• Variety of local load serving and voltage issues
• Suggested new substations
• Suggested capacitor additions
• Long-term 115-kV concept

Generation

• West Central CBED Study results
• Significant development of generation in Southwest Minnesota has exceeded the capacity of the existing transmission system
• Several projects underway to add additional transmission capacity for generation outlet

Hwy. 10/I-94 Corridor to St. Cloud

• New 345/115-kV source (transformer) at Sherburne County
• Upgrade of existing Twin Cities-St. Cloud 115-kV line
• CapX connection expected in St. Cloud and Twin Cities

Big Stone II Transmission Projects

• New coal-fired generator proposed at existing Big Stone site in SD is proposing new transmission in MN.
• Certificate of Need filed with MN PUC in September, 2005.
• Route permit filed with MN PUC in December, 2005

Preferred transmission project involves new transmission lines from the Big Stone plant to Morris and Granite Falls.

• Morris line includes new construction (Big Stone – Ortonville) and rebuilding existing 115-kV line to 230-kV (Ortonville – Johnson – Morris).
• Granite Falls line includes new construction (Big Stone – Canby) and rebuilding existing 115-kV line to a higher voltage (Canby – Granite Falls).
• Big Stone – Granite Falls portion of preferred transmission alternative being proposed as being built at 345-kV, but only operated at 230-kV until other regional 345-kV transmission is built in the Granite Falls area.
• Anticipated in-service date of the new generation is late 2011 to mid-2012.
