In 2011, Mortenson Construction worked through some challenging weather to construct the 165.6-MW Comber Wind project in Essex County, Ontario. Developed by Brookfield Renewable Energy Partners (BREP), Comber consists of 72, 2.3-megawatt Siemens turbines with 101-m rotors, currently the largest rotor available in the North American market. Mortenson was responsible for the engineering and construction of access roads, foundations, underground and overhead electrical collection system, a 230-kV substation, and erection of the turbines.
Mortenson and Brookfield’s construction partnership has been active in the Ontario wind market since 2005 with the development of Prince I and II Wind in Sault St. Marie, Ontario, followed by the construction of the 51-MW Gosfield Wind project. Gosfield is an adjacent and sister project of Comber. The combined wind farm is now Canada’s largest with an installed capacity of 216 MW. Mortenson and Brookfield have built more than 20% of Ontario’s wind generating capacity.
