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 operated hydroelectric power generators on the Winnipeg River and crude-oil-burning power plants at Minnedosa and Virden. On 1 April 1961, it was amalgamated with the Manitoba Hydro-Electric Board to form Manitoba Hydro.
