This is one of the many wind turbines on Wolfe Island, Ontario, Canada.
Wolfe Island Wind Farm is a large wind farm project located on Wolfe Island, Ontario (near Kingston, Ontario). The wind farm became operational on June 29, 2009.[1] It is owned and operated by Canadian Hydro Developers, Inc., through its subsidiary Canadian Renewable Energy Corporation (CREC). The power will be purchased by Hydro One for distribution to consumers.
Once completed, the 197.8 MW project was expected to generate approximately 594 gigawatt-hours (GW·h) of renewable power annually; enough to supply about 75,000 average households.[3] Over its first four full years of operation, generation proved to be around 495 GWh annually (see below).
Winds of 3.5 to 4 metres per second (11 to 13 ft/s) are required to generate power; when winds are less than 3 metres per second (9.8 ft/s), then power is not being generated.[4]
Key project components
Cross section of submarine power cable used in Wolfe Island Wind Project. The world's first 3-core XLPE submarine cable to achieve a 245 kV voltage rating.[5]
a 34.5-kilovolt (kV) electrical line collector system
a 34.5 / 230 kV transformer station
a 230 kV electrical line system provided by Nexans
230 kV interconnection facilities with the provincial grid at Hydro One's Gardiners Transformer Station
an operations and maintenance building.
CREC has optioned a total of approximately 2513 hectares (6,209 acres) of land for the proposed wind development.[6]
The facility will provide green jobs and generate landowner and community income through royalties, taxes, and the amenities agreement. Canadian Hydro has built a visitor centre at its property on the 5th line.[7]
The 2010 Bird and Bat report commissioned by Transalta, a component of the Post Construction Follow-up Plan (PCFP), states that over the first six months of operation bird mortality due to blade strike was 602 birds of which 13 were raptors. That reflects 6.99 birds per turbine over six months (almost 14 strikes per turbine per year). The industry standard for comparable wind facilities is generally 2 bird strikes per turbine per year. Over 1270 bats were killed in the same six-month period. The development is in a globally and continentally significant Important Bird Area. The PCFP was designed in response to stakeholder concerns over potential negative effects on bird populations, and is a partnership between Transalta, the Environment Canada and provincial Ministry of Natural Resources.[8]
