listed as a run-of-the-river dam and its commission date as 1920–1969. Its reservoir capacity is . The station was originally built in 1912-1913 for the Gatineau Power Company by William Kennedy Jr. but did not begin operating until 1920, following World War I, when it had two turbines in operation. A third turbine was added in 1923. In 1965, Gatineau Power was sold to Hydro-Québec, which added a fourth turbine in 1968. Chaudière Falls Generating Stations Hydro Ottawa operates two run-of-the-river hydroelectric generating stations without a dam. Generating Station 2 was built in 1891 and is leased from the National Capital Commission. Generating Station No. 4 was built in 1900 and is operated on land owned by the Government of Canada. The combined output is around 110 GWh per year. The stations were refurbished in the 2000s, including a small capacity increase in 2007. Hydro Ottawa purchased the site around the falls from Domtar Corporation in 2012, including the ring dam and water rights. A project started in 2015 and completed in 2017 increased the generating capacity of the stations from 29 to 58 MW. This project buried new turbines below grade next to the falls, enabling public access, new viewing platforms and a park celebrating Algonquin and industrial heritages.
