Manic-1 Generating Station
Manic-1 is a hydroelectric power station and dam at the mouth of the Manicouagan River west of Baie-Comeau, Quebec, Canada. The power station was commissioned between 1966 and 1967 and producing 184 MW, it is the smallest of the Manicouagan-Outardes project. History Between 1949 and 1956, to keep up with increasing electricity demands, the Manicouagan Power Company constructed and upgraded a 126 MW hydroelectric power station on the falls of the Manicouagan River' mouth. Electricity demand continued to rise with the construction of local grain elevators and an aluminum smelter. This power station was further supported and regulated by the McCormick Dam on St. Anne lake which Hydro-Québec had completed by 1959. However, as plans for the Manicouagan-Outardes project progressed, engineers discovered that water flow at the mouth of the Manicouagan could be better utilized. At Hydro-Québec's request, the Manicouagan Power Company further upgraded the McCormick plant's capacity to 190 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baie-Comeau
Baie-Comeau (; 2021 city population 20,687; CA population 26,643) is a city located approximately north-east of Quebec City in the Côte-Nord region of the province of Quebec, Canada. It is located on the shores of the Saint Lawrence River near the mouth of the Manicouagan River, and is the seat of Manicouagan Regional County Municipality. There are two urban area population centres within the city limits: Baie-Comeau proper, with a population of 9,100, and Hauterive, with a population of 11,147, as of the 2021 Canadian Census. The city is named after the adjacent Comeau Bay, which is named in honour of Napoléon-Alexandre Comeau, a Québécois naturalist. Baie-Comeau is the birthplace of former Prime Minister of Canada Brian Mulroney. History The oldest part of Baie-Comeau is the area known as ''Vieux-Poste'' (Old Post) near the mouth of the Amédée River where in 1889, the Saint-Eugène-de-Manicouagan Mission was founded by Eudists. In 1898, the first sawmill in the Côte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Head
Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth. Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a ''hydraulic gradient'' between two or more points. "Head" in fluid dynamics In fluid dynamics, ''head'' is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Quebec
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Hydro-Québec
Hydro-Québec is a government-owned public utility established in 1944 by the Government of Quebec. The company is in charge of the generation, transmission and distribution of electricity across Quebec. Its head office is located in Montreal. Origins In the years after the Great Depression, voices were raised in Quebec asking for a government takeover of the electricity business. Many of the criticisms leveled at the so-called "electricity trust" focused on high rates and excessive profits. Inspired by the example of Adam Beck, who had nationalized much of the electric sector in Ontario in 1906 as the Hydro-Electric Power Commission of Ontario, local politicians, such as Philippe Hamel and Télesphore-Damien Bouchard, strongly advocated moving Quebec towards a similar system. Soon after being elected Premier of Quebec in 1939, Adélard Godbout warmed to the concept of a state-owned utility. Godbout was outraged by the inefficient power system dominated by Anglo-Canadian economic i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
René-Lévesque Generating Station

Peak Demand
Peak demand on an electrical grid is simply the highest electrical power demand that has occurred over a specified time period (Gönen 2008). Peak demand is typically characterized as annual, daily or seasonal and has the unit of power. Peak demand, peak load or on-peak are terms used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than average supply level. Peak demand fluctuations may occur on daily, monthly, seasonal and yearly cycles. For an electric utility company, the actual point of peak demand is a single half-hour or hourly period which represents the highest point of customer consumption of electricity. At this time there is a combination of office, domestic demand and at some times of the year, the fall of darkness. Some utilities will charge customers based on their individual peak demand. The highest demand during each month or even a single 15 to 30 minute period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peaking Power Plant
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand. Although historically peaking power plants were frequently used in conjunction with coal baseload plants, peaking plants are now used less commonly. Combined cycle gas turbine plants have two or more cycles, the first of which is very similar to a peaking plant, with the second running on the waste heat of the first. That type of plant is often capable of rapidly starting up, albeit at reduced efficiency, and then over some hours transitioning to a more efficient baseload generation mode. C ...

Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravity, gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the #Phase and amplitude, phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see ''#Timing, Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal cycle, diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
