Ontario Power Generation's Niagara Tunnel Project includes the planning, design and construction of a tunnel to divert an additional 500 m³/s of water from the Niagara River upstream from the Horseshoe Falls to the existing Sir Adam Beck generating stations near Queenston, ON.  The tunnel is 10.2 km long with an internal diameter of 12.7 m. The estimated cost of the project is $1.6 billion. The design / build contractor used the world's largest hard‑rock tunnel boring machine (14.44 m diameter) to excavate the tunnel.

When operational, the Niagara Tunnel will deliver enough additional water to increase average annual energy output from OPG's Sir Adam Beck stations by about 1.6 billion kilowatt-hours - enough to supply 160,000 Ontario homes with clean, renewable hydroelectric power.

Rick Everdell is Project Director of the Niagara Tunnel Project at Ontario Power Generation Inc.  He is a graduate of the University of Waterloo (1976) with a BASc degree in Civil Engineering.
