Airport wind data is not always a good source as their instruments are designed to look for wind generation energy. Instead airports are trying to find wind shear and so they take their measurements too close to the ground. Wind reading sites set up in Ontario by the Ministry of Environment are often placed in poor locations and give poor wind readings. One example of this is the data collected for Lake Nippissing. The data is collected at the dock in downtown North Bay.
Wind turbines produce power in wind speeds above about 13 km/hour. In most places where wind turbines are located, the wind would be above this speed 70-80% of the time. Production then increases until it hits a maximum power produced at 55 km/hour. Wind turbines will typically shut down at wind speeds above 90 km/hour for safety reasons. These numbers will vary depending on the model of turbine selected.
