Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100 kW), "pico" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the Three Gorges Dam at 22,500 megawatts or the vast multiple projects of the Tennessee Valley Authority.
An underground power station is a type of hydroelectric power station constructed by excavating the major components from rock, rather than the more common surface-based construction methods.
Twin Falls is the site of a hydroelectric power station developed by the British Newfoundland Development Corporation (Brinco) to deliver power to mining operations in Labrador City and Wabush.
Newfoundland and Labrador Hydro, commonly known as Hydro, is a provincial Crown corporation that generates and delivers electricity for Newfoundland and Labrador, as well as portions of Quebec and the north-eastern areas of the United States.

The Petty Harbour Hydro Electric Generating Station is a hydroelectric generating station in Petty Harbour–Maddox Cove, Newfoundland and Labrador. It was constructed in 1898 and it was the first hydroelectric generating station in Newfoundland. It was built by the St. John's Street Railway Company, a company established by Robert Reid. Operation commenced on 19 April 1900.
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.
The Nelson River Hydroelectric Project refers to the construction of a series of dams and hydroelectric power plants on the Nelson River in Northern Manitoba, Canada. The project began to take shape in the late 1950s, with the planning and construction of the Kelsey dam and hydroelectric power station, and later was expanded to include the diversion of the upper Churchill River into the Nelson River and the transformation of Lake Winnipeg, the world's 11th largest freshwater lake, into a hydroelectric reservoir. The project is owned and operated by Manitoba Hydro, the electrical utility in the province.
According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2014, Canada consumed the equivalent of 85.7 megatonnes worth of oil of hydroelectricity, 9.8% of worldwide hydroelectric consumption. Furthermore, hydroelectricity accounted for 25.7% of Canada's total energy consumption. It is the third-most consumed energy in Canada behind oil and natural gas.
The Star Lake Hydroelectric Generating Station is a hydroelectric generating plant located at Star Lake in central Newfoundland. The plant is owned by Newfoundland and Labrador Hydro, and was first synchronized in 1998. It operates with a single vertical Francis turbine with a 450 ft head and a 173 million cubic metre capacity storage reservoir to generate 18.4 MW of electrical power.
The Churchill Falls Generating Station is a hydroelectric underground power station in Labrador. At 5,428 MW, it is the sixteenth largest in the world, and the second-largest in Canada, after the Robert-Bourassa generating station in northwestern Quebec.
The Menihek Hydroelectric Generating Station is a conventional hydroelectric generating station at Menihek Lake in Labrador. The dam and powerhouse are located in the Canadian province of Newfoundland and Labrador, 40 km (25 mi) south of the isolated town of Schefferville, Quebec and two First Nations communities: Matimekosh-Lac-John and Kawawachikamach. The generating station, two 69 kV power lines and the distribution networks in each community form an independent electricity network, off the main North American grid.
