Montana-Dakota also announced plans to expand its Diamond Willow wind facility by an additional 10.5MW. Diamond Willow, which went online in late 2007, is located near Baker, Montana. The expansion project will include seven additional wind turbines on existing leased land, and increase the capability of the site to 30MW. Both projects are pending regulatory approval. The North Dakota site will feature 13 turbines and is located close to a Montana-Dakota transmission line for interconnection. The additional generation from both projects will provide electricity for about 10,000 average homes in Montana, North Dakota and South Dakota. Both projects are scheduled to become commercial in late 2009. When finished, Montana-Dakota will have nearly $125 million invested in wind generation and other renewable projects to serve its electric customers in Montana, North Dakota and South Dakota.
