Butte, Mont., March 21, 2012 — NorthWestern Corp. issued a notice to proceed to Compass Wind to move forward with construction on the 40 MW Spion Kop Wind Project near the central Montana community of Geyser.
The Montana Public Service Commission approved placement of the $86.1 million project into the company’s regulated rate base in mid-February. Both the wind energy and associated renewable energy credits will be used to meet the renewable portfolio standards obligations in Montana law.
Under Montana’s renewable portfolio standards, 15-percent of NorthWestern Energy’s total energy portfolio must be produced from renewable generation by 2015.
The Spion Kop Wind Project will include 25 1.6 MW GE wind turbines near Geyser, Montana. Construction is set to begin later this spring, and the project is due to be completed by the end of the year.
