Wolfe Island Wind Project (197.8 MW) - Wolfe Island

Commercial Operation on June 26, 2009

The Wolfe Island Wind Project is operated and was developed by the Canadian Renewable Energy Corporation, a wholly-owned subsidiary of Canadian Hydro Developers, Inc., located directly on Wolfe Island, a few kilometres off the shore of Kingston in the Township of Frontenac, Ontario. Subsequently, TransAlta Energy Corp. acquired Canadian Hydro Developers, Inc. on October 5, 2009.

This 197.8 MW wind plant is comprised of 86 wind turbines and each turbine has a rated capacity of 2,300 kilowatts.  

A major component that truly sets Wolfe Island apart from other wind installations in North America is the submarine cable used to transmit power from the Island to the mainland.  It is 7.8 km long and lies on the bed of Lake Ontario in the Lower Gap between the Island and the City of Kingston.  It has a diameter of approximately 235 mm and weighs roughly 736,000 kg.  The submarine cable consists of three high voltage current-carrying copper conductors and there is also one fiber optic cable consisting of 36 individual fibers.  The conductors are held in place by hollow filler strands that act like wedges between the conductor and outer sheath.  The armour is comprised of steel strands that form the protective sheath, wrapped in a water tight covering and the cable rests on the waters’ bed and at some points reaches depths of 30 meters.  It is kept in place solely by its own weight.  This 7.8 km long cable is the world’s first 3-core XLPE submarine cable to achieve a voltage rating of 245 kV.

The submarine cable was installed to interconnect the wind plant to the existing Hydro One 230 kV Gardiner Transformer Station, which feeds renewable energy into the Ontario electricity market administered by the Independent Electricity System Operator.

The plant is will generate approximately 593,500 megawatt-hours per year of renewable energy.  Wolfe Island Wind Plant is the second largest wind farm in Canada, second to Ontario’s Melancthon Wind Farm with a capacity of 199.5 MW which is also owned and operated by the same developer.
