New tunnel to optimize hydro potential at Niagara
27 May, 2009
Ontario Power Generation’s Niagara tunnel project includes the planning, design and construction of a 10.2km long, 12.7m internal diameter tunnel and associated facilities to divert an additional 500m3/sec of water from the Niagara river upstream from the Horseshoe Falls to the existing Sir Adam Beck generating stations near Queenston. The design/build contractor, Strabag, is using the world’s largest hardrock tunnel boring machine to excavate the tunnel. By Richard A Everdell
