Niagara Tunnel Project
Ontario, Canada
The Niagara Tunnel Project was part of a series of major additions to the Sir Adam Beck hydroelectric generation complex in Niagara Falls, Ontario, Canada. Water delivered by the major new tunnel complements other upgrades to the Sir Adam Beck Hydroelectric Generating Stations, resulting in more efficient use of the Niagara River's hydro power. The project's new 12.7 metres (42 ft) diameter, 10.2 kilometres (6.3 mi) long tunnel was officially placed into service on 21 March 2013, helping to increase the generating complex's nameplate capacity by 150 megawatts, with the extra power produced enough for approximately 160,000 homes.
