Saint Peter, Minnesota: Public Works

Electric System Transmission/Substation Upgrades 2010/2011

Improvements have been planned to include a new substation on the north end of Saint Peter, the proposed site is adjacent to the Sunrise Drive Water Tower on city owned property. A new underground transmission line is scheduled to be installed starting in August that would link the existing Broadway Substation to the new Sunrise Substation. A new overhead transmission line is scheduled to be installed in Nicollet County Rd #15 and #40 to connect the substations to the existing transmission line west of the city. Our electrical provider, Southern Minnesota Municipal Public Power Agency (SMPPA) is the lead agency and will coordinate the work that is planned. City staff in conjunction with the underground transmission work will be installing two sets of conduit in the same trench which will provide for future electric distribution lines. The contractor will install two conduits for a fiber communication system between substations for control and monitoring systems. The contractor will be installing about three and one half miles of trench, four and one fourth miles of underground transmission line and two and one third miles of trail. The underground portion of the project cost is $3.676 million dollars, which will be funded on a shared basis with SMMPA.

Underground work will be completed this fall and the contractor has scheduled the wire to be installed in the conduit starting April 1, 2011. The new system should be operational by December 2011.
