For the last year, Mortenson Construction, one of North America's leading renewable energy contractors, has worked through challenging weather conditions to construct the 165.6- megawatt 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-meter rotors - currently the largest rotor available in the North American market. Mortenson was responsible for the engineering and construction of the 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-megawatt Gosfield Wind project.

Gosfield is the adjacent, sister project of Comber, and the combined wind farm is now Canada's largest with an installed capacity of 216 megawatts; producing enough electricity to power over 70,000 homes.

"We are pleased to have continued our long-term relationship with Brookfield to establish a strong portfolio of renewable energy projects in Ontario," says Mark Donahue, Vice President and General Manager at Mortenson Construction.

"Together we have built more than 20 percent of Ontario's wind generating capacity."

BREP Vice President of Wind Operations, Berk Gursoy, says Mortenson was a valued project business partner. "The determination, effort and professionalism of the Mortenson team were very apparent throughout construction, and played a significant part in delivering this exceptional wind project on scope, schedule and budget."
