Sir Adam Beck Hydroelectric Generating Stations are two hydroelectric generating stations in Niagara Falls, Ontario, Canada. The stations divert water from the Niagara and Welland Rivers above Niagara Falls which is then released into the lower portion of the Niagara River, and together produce up to.Adam Beck IAdam Beck I contains 10 generators and first produced power in 1922. It was originally called the Queenston-Chippawa Hydroelectric Plant and was renamed after Adam Beck in 1950 on the twenty fifth anniversary of his death. The water is diverted through the Chippawa-Queenston Power Canal from the Welland River.As the first large-scale hydroelectric generation project in the world, Adam Beck I was designated a National Historic Site of Canada in 1990.Adam Beck IIAdam Beck II contains 16 generators and first produced power in 1954. The water was first diverted from the Niagara River by two five-mile tunnels under the city of Niagara Falls, Ontario, that start above the falls. A reservoir was created that permits the holding of water, diverted during the night, for use during the day.Between 2006 and 2013, Adam Beck II underwent major civil engineering projects with the addition of a major underground water supply tunnel built by the Niagara Tunnel Project in order to improve its generation output. Water delivered by the major new tunnel complemented 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.
