Granite Canal Hydroelectric Generating Station
The Granite Canal Hydroelectric Generating Station is a component of the Newfoundland and Labrador Hydro Corporation's Bay d’Espoir Hydro Electric Development system. The generating station has a rated capacity of 40 MW with an annual average energy production of 224 gigawatt hours (GWh). The generating unit at Granite Canal utilizes approximately 37 metres of head with a rated plant flow of 122.4 cubic metres per second. The unit is equipped with a Kaplan turbine and was first synchronized on May 26, 2003. A fish habitat compensation system was included in this development to ensure any aquatic habitat loss was avoided, reduced or replaced. A Fish Habitat Compensation Agreement was signed with Fisheries and Oceans Canada Fisheries and Oceans Canada (DFO; french: Pêches et Océans Canada, MPO), is a department of the Government of Canada that is responsible for developing and implementing policies and programs in support of Canada's economic, ecological and sc ... to ensure ...

Newfoundland And Labrador Hydro
Newfoundland and Labrador Hydro (NL 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. Since 2007, Hydro has been a subsidiary of the provincial Crown-owned energy holding company Nalcor Energy. Newfoundland and Labrador Hydro's installed generating capacity, 8034 megawatts (MW), is the fourth largest of all utility companies in Canada. Generating assets consist of 12 hydroelectric plants, including the Churchill Falls hydroelectric plant, which is the second largest underground power station in the world, with a rated capacity of 5,428 MW of power, one oil-fired plant, four gas turbines and 26 diesel plants. Every year, Hydro generates and transmits over 80% of the electrical energy consumed by Newfoundlanders and Labradorians – over 6,487 GWh of energy in 2004. Hydro also distributes power directly to 35,000 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay D’Espoir Hydro Electric Development
The Bay D'Espoir Hydroelectric Development, built by the Newfoundland and Labrador Power Commission is located on the south coast of Newfoundland and Labrador, Newfoundland near the rural community of Bay d'Espoir. It was the second major hydroelectric project undertaken on Newfoundland and Labrador, 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 gov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. But t ...

Aquatic Ecosystem
An aquatic ecosystem is an ecosystem formed by surrounding a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Freshwater ecosystems may be lentic (slow moving water, including pools, ponds, and lakes); lotic (faster moving water, for example streams and rivers); and wetlands (areas where the soil is saturated or inundated for at least part of the time). Types Marine ecosystems Marine coastal ecosystem Marine surface ecosystem Freshwater ecosystems Lentic ecosystem (lakes) Lotic ecosystem (rivers) Wetlands Functions Aquatic ecosystems perform many important environmental functions. For example, they recycle nutrients, purify water, attenuate floods, recharge ground water and provide habitats for wildlife. Aquatic ecosystems are also used for ...

Fisheries And Oceans Canada
Fisheries and Oceans Canada (DFO; french: Pêches et Océans Canada, MPO), is a department of the Government of Canada that is responsible for developing and implementing policies and programs in support of Canada's economic, ecological and scientific interests in oceans and inland waters. Its mandate includes responsibility for the conservation and sustainable use of Canada's fisheries resources while continuing to provide safe, effective and environmentally sound marine services that are responsive to the needs of Canadians in a global economy. The federal government is constitutionally mandated for conservation and protection of fisheries resources in all Canadian fisheries waters. However, the department is largely focused on the conservation and allotment of harvests of salt water fisheries on the Atlantic, Pacific and Arctic coasts of Canada. The department works toward conservation and protection of inland freshwater fisheries, such as on the Great Lakes and Lake Winni ...

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.
