Hydroelectricity, or hydroelectric power, is electricity generated from hydropower. Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, 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.
The Churchill River, formerly known by other names, is a river in Newfoundland and Labrador, Canada. It flows east from the Smallwood Reservoir into the Atlantic Ocean via Lake Melville. The river is 856 km (532 mi) long and drains an area of 79,800 km2 (30,800 sq mi), making it the longest river in Atlantic Canada.
Churchill Falls is a 245 ft (74.7 m) high waterfall on the Churchill River in Labrador, Canada. Formerly counted among the most impressive natural features of Canada, the diversion of the river for the Churchill Falls Generating Station has cut off almost all of the falls' former flow, leaving a small stream winding through its old bed and trickling down the rocks.
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. Between 2007 and 2021, NL Hydro was a subsidiary of the provincial Crown-owned energy holding company Nalcor Energy.
The Bay D'Espoir Hydroelectric Development, built by the Newfoundland and Labrador Power Commission is located on the south coast of Newfoundland near the rural community of Bay d'Espoir. It was the second major hydroelectric project undertaken on Newfoundland.
Churchill Falls (Labrador) Corporation Limited, also known as CF(L)Co or CFLco is a Canadian electric company. The company was founded in 1961 and is based in St. John's, Newfoundland and Labrador. Churchill Falls (Labrador) Corporation Limited operates as a subsidiary of Newfoundland and Labrador Hydro.
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 Smallwood Reservoir is the reservoir created for the Churchill Falls Generating Station in the western part of Labrador, Canada. Unlike other reservoirs, water is contained not by a single large dam, but by a series of 88 dikes that total 64 km (40 mi) in length in the drainage area of the Churchill River. It is named in honour of Joey Smallwood, the first premier of Newfoundland.
Sir Adam Beck Hydroelectric Generating Stations are two hydroelectric generating stations in Niagara Falls, Ontario, Canada. Sir Adam Beck Generating Station I, Sir Adam Beck Generating Station II and the Sir Adam Beck Pump Generating Station are all owned by Ontario Power Generation. Following the development of several smaller generating stations around Niagara Falls in the late 19th and early 20th centuries, the Province of Ontario authorized the construction of the first major publicly owned generating station in the province. At the time it was built, it was the largest hydroelectric generating station in the world.
The Robert Moses Niagara Hydroelectric Power Station is a hydroelectric power station in Lewiston, New York, near Niagara Falls. Owned and operated by the New York Power Authority (NYPA), the plant diverts water from the Niagara River above Niagara Falls and returns the water into the lower portion of the river near Lake Ontario. It uses 13 generators at an installed capacity of 2,525 MW (3,386,000 hp) with an average annual net generation of 15,897,000 MWh between 2014 and 2023, and a capacity factor of 71.9%.
Ossokmanuan Lake is a reservoir lake in western Labrador, Newfoundland and Labrador, Canada. It was formed in the early 1960s by the Twin Falls hydroelectric plant. In 1976 it had a reported 2.8×109 m3 (9.9×1010 cu ft) of active storage.
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 2019, Canada produced 632.2 TWh of electricity with 60% of energy coming from Hydroelectric and Tidal Energy Sources).
Nalcor Energy was an energy corporation which headquartered in St. John's, Newfoundland and Labrador. A provincial Crown corporation under the Government of Newfoundland and Labrador, Nalcor Energy was created in 2007 to manage the province's energy resources.
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 Muskrat Falls Generating Station is a hydroelectric generating station in the Labrador region of Newfoundland and Labrador, Canada. It comprises part of the remaining 35 per cent of the Churchill River that was not developed by the Churchill Falls Generating Station. The station at Muskrat Falls has a capacity of over 824 MW and provides 4.5 TWh of electricity per year.
The history of electricity sector in Canada has played a significant role in the economic and political life of the country since wide-scale industrial and commercial power services spread across the country in the 1880s. The development of hydropower in the early 20th century has profoundly affected the economy and the political life in Canada and has come to symbolize the transition from "old " industrialism of the 19th century to a "new", modern and diversified, Canadian economy.
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.
The Naskaupi River is the second largest river in Labrador, Canada. Its drainage basin lies north of that of Labrador's longest river, the Churchill River. Like the Churchill River, it drains into the western end of the estuary known as Lake Melville.
