Canadian Hydro Developers, a veteran developer based in Calgary, has ordered 86 SWT 2.3 MW turbines from Siemens Power Generation for its Wolfe Island Wind project near Kingston in eastern Ontario. The wind farm, which at 197.8 MW is the largest to win a power purchase contract so far in Canada, is due to be operational in fall 2008. Canadian Hydro's order is Siemens' second in the Canadian wind market. The turbine maker is also supplying 44 of its 2.3 MW machines to Kruger Energy Group for the 101.2 MW Port Alma wind farm. That project, on the north shore of Lake Erie in southern Ontario, is scheduled to be operational by October 31, 2008. North American orders for Siemens turbines total more than 750 MW so far this year and have a combined value exceeding $1.1 billion. The company says it expects negotiations for further orders in both Canada and the US to be completed shortly.
