The Proof Line wind power facility commenced commercial operations in December 2009.
The Ferndale, Ravenswood, and Proof Line wind power facilities, located in the South Bruce Peninsula in Ontario, have a total installed capacity of approximately 22 megawatts and use Vestas wind turbines (V80-1.8 MW and V82-1.65 MW turbines). The electricity generated by all three wind facilities is sold to the Ontario Power Authority under Renewable Energy Standard Offer Program (RESOP) contracts.
