Project value USD 1.6 Billion


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 underground tunnel complements other upgrades to the Sir Adam Beck generating complex, resulting in a significant increase to the efficient use of the Niagara River’s hydro power. The project’s new 12.7 meters (42 ft.) diameter, 10.2 kilometers (6.3 mi) long tunnel was officially placed into service on March 21st, 2013, helping to increase the generating complex’s nameplate capacity by 150 megawatts, with the extra power producing enough for approximately 160,000 homes.
