Toronto Hydro Energy Services Inc. and the WindShare Co-operative say that maintenance on the wind turbine at the Exhibition Place site is scheduled to take place between April 25 and 30. 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."

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:

  • 94 per cent operating availability rate;
  • 1,000 megaWatt-hours of electricity production, the equivalent of powering 200 homes with 100% "green" electricity; and
  • a displacement of 380 Tonnes of CO2, the equivalent of taking 1,300 cars off the road or planting 30,000 trees each year.

WindShare is a for-profit wind power co-operative, the first of its kind in Canada. WindShare develops locally owned wind power projects that are scaled to the size and characteristics of the host community. WindShare was the first development project by the TREC Renewable Energy Co-operative (, a non-profit, environmental co-operative that develops community-owned renewable energy projects and educates Ontarians about renewable energy, energy conservation and the community power model. TREC will launch a community solar co-operative, ‘SolarShare’ in summer 2011.
