Montana-Dakota Utilities Co., a division of MDU Resources Group Inc., signed a power purchase agreement with Thunder Spirit Wind LLC, a unit of Wind Works Power Corp.
The agreement is for about 105 MW of installed capacity of wind turbine generators to be located in southwest North Dakota near Hettinger. The generation will interconnect at Montana-Dakota’s substation near Hettinger. The project is expected to begin commercial operation in the fourth quarter of 2015.
Montana-Dakota issued a request for proposal earlier this year for electric capacity and energy. The Thunder Spirit Wind proposal will provide Montana-Dakota customers with stable pricing over the 25-year contract.
In addition to renewable energy owned by Montana-Dakota, the agreement with Thunder Spirit Wind means 20 percent of Montana-Dakota’s energy supply requirements will come from renewable resources.
