Established in 1898, the Shawinigan Water & Power Company was one of the dominant, privately owned hydroelectric companies in Canada until 1963, when it became a part of Hydro-Québec.
It was based in Shawinigan, Quebec.
The company established the Shawinigan 1 (c. 1901), Shawinigan 2 (1911) and Shawinigan 3 (1948) plants. Shawinigan 1 ceased production in the early 1950s.
