The project is located in Vulcan County, southern Alberta, about 165 kilometres south-east of Calgary. On completion it will be the largest wind farm in western Canada.
Under the purchase, EDF and Enbridge will each own 50% of the project. Greengrate will continue to work on the project through its development.
At the same time, Vestas has received a 299MW order for 166 V100 low wind 1.8MW turbines. Vestas said it aimed to supply the turbines in the second half of 2013 with a view to completing the project by mid-2014.
Vestas originally received an order for Blackspring Ridge in 2011. At the time, it was reported the project was to be financed via a 20-year contract with San Francisco-based Pacific Gas & Electric (PG&E) with the aim of a 2012 completion.
