SP 69-kV Transmission Rebuild Project

Great River Energy, wholesale electric supplier to Connexus Energy, is planning to rebuild approximately 11 miles of 69,000-volt (69-kilovolt or 69-kV) overhead transmission line in the cities of Ham Lake and Blaine in Anoka County. The SP transmission line, originally constructed in the 1950s, requires rebuilding due to its age and condition, to enhance the reliability of the electrical power supply.

This project involves the construction of approximately 11 miles of transmission line from the Soderville Substation, located at the corner of Minnesota Highway 65 and County Road 18, to the Blaine Substation, located south of the County Road 14 and Lexington Avenue Northeast intersection.

The transmission line will be rebuilt along the existing corridor as follows:

• From the Soderville Substation, the line will run north for approximately 0.23 miles and then turn east approximately 0.56 miles to Swedish Drive Northeast.
• It will then head south for approximately 1.75 miles to County Road 60, turning east to run approximately one mile to Xylite Street Northeast.
• The line will continue south for approximately 1.76 miles along Xylite Street Northeast to 149th Avenue Northeast, then turn easterly for approximately one mile to Naples Street and then proceed south for approximately one mile to Bunker Boulevard Northeast.
• Finally, it will follow Bunker Boulevard Northeast for approximately one mile east to Lexington Avenue Northeast and turn to run south for approximately 2.5 miles to terminate at the Blaine Substation.
