Mortenson Construction was recently selected by San Francisco-based developer, NaturEner for the construction of the Rim Rock Wind Project. Located on nearly 21,000 acres about 20 miles north of NaturEner’s Glacier I and 2 Wind projects, previously constructed by Mortenson, Rim Rock will generate189-MW of wind power.
Mortenson is responsible for the design and construction of access roads, foundations, erection of 126 Acciona 1.5-megawatt turbines, overhead and underground electrical collection system, two 230 kV substations, a generator tie line, and an O&M facility. Construction began late October, proceeding through the winter months and is expected to complete in October, 2012.
Montana’s wind attributes are unique to the industry. According to AWEA, the state is ranked third in the U.S. for potential wind generating capacity, with more than 944,000 MW available for production. This much wind energy could produce more than 210 times the state’s current electricity needs. Along with Montana’s vast wind resources, the siting for this project was selected because of the ease of access to the property and the business-friendly development atmosphere in this part of Montana. This is NaturEner’s third project in the area.
Since entering the renewable energy market in 1995, Mortenson Construction has constructed more than 100 wind projects generating more than 11,000 MW of renewable power across the United States and Canada. Mortenson’s Renewable Energy Group also constructs facilities that generate solar power, biofuels, and hydro-electric power.
