They would go on the north side of Lake Shore Blvd. W. one opposite Ontario Place, the other at the site's western tip.
But Joyce McLean of Toronto Hydro says a decision won't be made until summer's end.
TREC Windpower Co-operative and Toronto Hydro Energy Services Inc. who jointly own the turbine there received approval from the board of governors at Exhibition Place to lease land for them, should the project go ahead.
There's reason for more turbines: Money. Ontario's new Green Energy Act raised the producer's price for wind-powered electricity to 14.4 cents a kWh, from 11 cents.
If the partners decide to install the turbines, they would pay $76,000 on the two leases over 15 years.
Dianne Young, chief executive of Exhibition Place, said more turbines would help meet the goal of having the site produce as much electricity as it uses.
