The W. A. C. Bennett Dam is a large hydroelectric dam on the Peace River in northern British Columbia, Canada. At 186 metres (610 ft) high, it is one of the world's highest earth fill dams. Construction of the dam began in 1961 and culminated in 1968. At the dam, the Finlay, the Parsnip and the Peace rivers feed into Williston Lake, also referred to as Williston Reservoir. It is the third largest artificial lake in North America as well as the largest body of fresh water in British Columbia. Williston Lake runs 250 kilometres north–south and 150 kilometres east–west.
The British Columbia Hydro and Power Authority, operating as BC Hydro, is a Canadian electric utility in the province of British Columbia. It is the main electricity distributor, serving more than 4 million customers in most areas, with the exception of the City of New Westminster, where the city runs its own electrical department and portions of the West Kootenay, Okanagan, the Boundary Country and Similkameen regions, where FortisBC, a subsidiary of Fortis Inc. directly provides electric service to 213,000 customers and supplies municipally owned utilities in the same area. As a provincial Crown corporation, BC Hydro reports to the BC Ministry of Energy, Mines and Low Carbon Innovation, and is regulated by the British Columbia Utilities Commission (BCUC). Its mandate is to generate, purchase, distribute and sell electricity.
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants. However, when constructed in lowland rainforest areas, where part of the forest is inundated, substantial amounts of greenhouse gases may be emitted.
Mica Dam is a hydroelectric embankment dam spanning the Columbia River 135 kilometres north of Revelstoke, British Columbia, Canada. It was built as one of three Canadian projects under the terms of the 1964 Columbia River Treaty and is operated by BC Hydro. Completed in 1973, the Mica powerhouse had an original generating capacity of 1,805 megawatts (MW). Mica Dam, named after the nearby settlement of Mica Creek and its associated stream, in turn named after the abundance of mica minerals in the area, is one of the largest earthfill dams in the world. The reservoir created by the dam is Kinbasket Lake. Water from the dam flows south directly into Revelstoke Lake, the reservoir for the Revelstoke Dam. Mica Dam is the tallest dam in Canada and second tallest in North America after the Chicoasén Dam in Mexico and it is the farthest upstream dam on the Columbia River. The dam's underground powerhouse was the second largest in the world at the time of its construction, and was the first 500 kV installation of sulphur hexafluoride (SF6) insulated switchgear in the world.
The Manitoba Hydro-Electric Board, operating as Manitoba Hydro, is the electric power and natural gas utility in the province of Manitoba, Canada. Founded in 1961, it is a provincial Crown Corporation, governed by the Manitoba Hydro-Electric Board and the Manitoba Hydro Act. Today the company operates 16 interconnected generating stations. It has more than 527,000 electric power customers and more than 263,000 natural gas customers. Since most of the electrical energy is provided by hydroelectric power, the utility has low electricity rates. Stations in Northern Manitoba are connected by a HVDC system, the Nelson River Bipole, to customers in the south. The internal staff are members of the Canadian Union of Public Employees Local 998 while the outside workers are members of the International Brotherhood of Electrical Workers Local 2034.
The Columbia River Treaty is a 1961 agreement between Canada and the United States on the development and operation of dams in the upper Columbia River basin for power and flood control benefits in both countries. Four dams were constructed under this treaty: three in the Canadian province of British Columbia and one in the U.S. state of Montana.

The electricity sector in Canada has played a significant role in the economic and political life of the country since the late 19th century. The sector is organized along provincial and territorial lines. In a majority of provinces, large government-owned integrated public utilities play a leading role in the generation, transmission, and distribution of electricity. Ontario and Alberta have created electricity markets in the last decade to increase investment and competition in this sector of the economy.

Independent Power Producer (IPP) projects have had a significant presence in British Columbia since the 1980s. Their relationship with BC Hydro grew from the province's need to supply growing energy demands and implementation of the 2002 Energy Strategy, which mandated that BC Hydro would purchase its energy supply from IPPs rather than generating the supply itself. There are a variety of power projects in BC, with the most popular being hydroelectricity and biomass projects. In recent years, more attention has been placed on the environmental effects of IPP projects and the social implications it has to residents living around the project development sites. Despite the decline in demand for new IPP projects, in 2016 they supplied 20,000 GWh, one-third of BC Hydro's total.
The Aniwhenua power station is a hydroelectric power facility in Bay of Plenty in New Zealand located on the Rangitaiki River upstream of the Matahina Power Station.
