Upper Salmon Hydroelectric Development
The Upper Salmon Hydro Development, a hydroelectric plant in Newfoundland and Labrador. It utilises a portion of the residual head between Meelpaeg Lake Reservoir and Round Pond within the watershed Watershed is a hydrological term, which has been adopted in other fields in a more or less figurative sense. It may refer to: Hydrology * Drainage divide, the line that separates neighbouring drainage basins * Drainage basin, called a "watershe ... of the Bay d'Espoir Hydroelectric Development. The plant operates at a normal supply level of 241 m under a net head of 51 metres. The average rated flow of 189.5 m3/s is used to generate 84 megawatts (MW) of electrical power with an average annual production of 541 GWh. The unit, which is equipped with a Francis turbine, was first synchronized on January 19, 1983.

Newfoundland And Labrador
Newfoundland and Labrador (; french: Terre-Neuve-et-Labrador; frequently abbreviated as NL) is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region of Labrador, having a total size of 405,212 square kilometres (156,500 sq mi). In 2021, the population of Newfoundland and Labrador was estimated to be 521,758. The island of Newfoundland (and its smaller neighbouring islands) is home to around 94 per cent of the province's population, with more than half residing in the Avalon Peninsula. Labrador borders the province of Quebec, and the French overseas collectivity of Saint Pierre and Miquelon lies about 20 km west of the Burin Peninsula. According to the 2016 census, 97.0 per cent of residents reported English as their native language, making Newfoundland and Labrador Canada's most linguistically homogeneous province. A majority of the population is descended from English and Irish ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the ''drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ...

Bay D'Espoir Hydroelectric Development
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. History The hydroelectric potential of this area was known by the early 1920s but its development was not seriously considered until 1954 when British Newfoundland Development Corporation (BRINCO) became interested in the site. In 1957 a Shawinigan Engineering survey confirmed the feasibility of building a hydroelectric plant. By 1959 BRINCO had set up a subsidiary, Southern Newfoundland Power and Development Corporation, to carry out the project. However, the subsidiary was unable to attract industrial customers to the area; this, it felt, was necessary before undertaking the project, so in 1964 it sold all its rights and assets to the Newfoundland Government. The government, by taking over the project, became elig ...

Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines Radial turbine, radial and Axial flow turbine, axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the Hydraulic head, head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm.

Hydroelectric Power Stations In Newfoundland And Labrador
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). 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.
