The turbine's rotor and generator will be removed, serviced and re-installed with the aid of two large construction cranes. This scheduled maintenance will focus on replacing the main bearing of the turbine and updating the controls.
"The bearing change-out is intended to extend the Ex Place turbine's lifespan," explains Dianne Saxe, President of WindShare. "On behalf of our 400 community members, we're pleased that this technical maintenance will help continue the generation of clean renewable wind power in Toronto."
The maintenance is expected to be completed by April 30.
In 2002, Toronto Hydro Energy Services Inc., with WindShare, constructed Canada's first urban wind turbine. Situated on a busy commuter route and in a major cultural, business and tourist site in Toronto it has helped to raise awareness about the nature of wind power. In 2010, the wind turbine achieved:
A 94 per cent operating availability rate
A 1,000 megawatt-hours of electricity production, the equivalent of powering 200 homes with 100 "green" electricity
A displacement of 380 tonnes of CO2, the equivalent of taking 1,300 cars off the road or planting 30,000 trees each year.
