The Pickering Wind Generating Station, located on OPG's Pickering Nuclear site, was installed in August, 2001 and at 1.8 (MW) is one of North America's largest wind turbines. The turbine was manufactured by Vestas Wind Systems, the world's largest manufacturer of wind turbines, in Denmark.
Capacity of this 117-metre turbine, called the Pickering Wind Generating Station, is 1.8 MW. The 78 metre steel tower is topped with a generating unit turned by a three-blade rotor." The rotating nacelle, found at the top of the tower where the blades meet, is "about the size of an inter-city bus." Power is fed via underground cables into the electrical grid system and can produce enough emission-free energy to supply the annual electricity needs of about 600 average Ontario homes. During the first year of operation Pickering Wind produced 2.2 Gwh (1 Gwh=1,000 MWh) hours of electricity and was available 86 per cent of the time.
