Ontario set to expand Sir Adam Beck station in Niagara Falls

Canadian Press reports that the Ontario government has decided to go ahead with expanding power generation at historic Niagara Falls.
The Niagara Tunnel Project is expected to be completed by 2009 and to cost an estimated $600 million, said Energy Minister Dwight Duncan, in an interview.
The new tunnel will be the third feeding the 50-year old Sir Adam Beck station owned by Ontario Power Generation. It will involve a new 10.5-kilometre long tunnel under the city to divert more water to the station, increasing capacity by about 15%.
The project is expected to produce an additional 1.6 terawatt-hours of electricity per year, adding to the current 12 terawatts that the station produces annually.
A report in the Toronto Star said that Ontario Power Generation will seek competitive bids from international companies to do the project. It also said that environmental assessments have already been completed.
