Manitoba Business: Manitoba Power Commission / Manitoba Hydro-Electric Board / Winnipeg Hydro / Manitoba Hydro
Several corporate entities have existed in Manitoba to develop and market electric power in the province.
Manitoba Power Commission
The Manitoba Power Commission was created in early 1919 with the objective of delivering inexpensive electrical power to rural Manitobans at the cost of production. It constructed transmission lines around the province and operated crude-oil-burning power plants at Minnedosa and Virden. Initially, there was a single commissioner but it expanded to three commissioners in 1931.
On 1 April 1961, the Commission was amalgamated with the Manitoba Hydro-Electric Board to form Manitoba Hydro, although the merged entity is still known legally as the Manitoba Hydro-Electric Board.
Assistant General Managers
Manitoba Hydro-Electric Board
The Manitoba Hydro-Electric Board was established by the provincial government in 1949 to coordinate the development and operation of all electrical generating facilities in the province. For its first two years, it was operated by civil servant Donald Stephens, with formal appointments starting in 1951. The Board acquired the electrical assets of the Winnipeg Electric Company in January 1953. Eight years later, it was amalgamated with the Manitoba Power Commission to form Manitoba Hydro, although the combined entity continued to be known legally as the Manitoba Hydro-Electric Board.
