Kettle Generating Station
The Kettle Generating Station, also known as Kettle Rapids Generating Station, is a run-of-the-river hydroelectric power station on the Lower Nelson River in Manitoba, Canada. It is located northwest of Gillam. As part of the Nelson River Hydroelectric Project, the power station was completed in 1973 and the last generator commissioned in 1974. It has an installed capacity of and is the second largest power station in Manitoba. Construction on the station began in the spring of 1966 and it was carried out in several phases. First, the power house was constructed after a circular coffer dam was set on the right side of the river. Second, the spillway was built adjacent and to the left of the power house while the river flowed through the power house in the meantime. Once the spillway was complete the entire the river was diverted through it. At this point, the turbines and generators were loaded into the power house and the earth-fill section on the dam's left bank was completed. ...

Gillam, Manitoba
Gillam is a town on the Nelson River in northern Manitoba, Canada. It is situated between Thompson and Churchill on the Hudson Bay Railway line. Many residents of Gillam are employed by Manitoba Hydro at one of their many facilities or support groups. Located within Gillam's boundaries, Hydro has four hydro dams—Kettle Generating Station, Long Spruce Generating Station, Limestone Generating Station (the largest in Manitoba) and Keeyask (in construction)—three HVDC stations—Radisson, Henday, and Keewatinohk—and a few support groups. History The large Gillam Local Government District () was established by the Manitoba government in the mid-1960s to facilitate development of hydroelectricity on the lower Nelson River. At , Gillam is considered to be the 9th largest city or town in Canada by area, although the majority of the encompassing area of the District is largely uninhabited and undeveloped, but filled with many lakes, rivers and large forests of pine trees. ...

Hydroelectric Power Stations In Manitoba
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.

Dams In Manitoba
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] |
Energy Infrastructure Completed In 1974
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Limestone Generating Station
Limestone Generating Station is a run-of-the-river hydroelectric dam on the Nelson River approximately north of Winnipeg near Gillam, Manitoba. Part of the Nelson River Hydroelectric Project, Limestone was Manitoba Hydro's fifth and largest generating station to be built on the Nelson River. The station was built on the Nelson River at Long Spruce Rapids. The site is approximately downstream of Manitoba Hydro's Long Spruce Generating Station. The dam is owned and operated by Manitoba Hydro. It has ten generating units with a capacity of 1,330 megawatts and annual generation around 8.5 terawatt-hours. Although work at the site began in 1976 with a cofferdam completed in 1978, construction was suspended owing to a slowing of demand for electric power. The project resumed in 1985, with the first generating unit delivering power in 1990 and completion in 1992. Construction cost was $CDN 1.43 billion; favorable economic conditions at the time resulted in lower cost than budget. ... [...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] |
Nelson River
The Nelson River is a river of north-central North America, in the Canadian province of Manitoba. The river drains Lake Winnipeg and runs before it ends in Hudson Bay. Its full length (including the Saskatchewan River and Bow River) is , it has mean discharge of , and has a drainage basin of , of which is in the United States. Geography The Nelson River flows into Playgreen Lake from Lake Winnipeg then flows from two channels into Cross Lake. The east channel and the Jack River flow from the southeast portion of the lake into Little Playgreen Lake then the Nelson east channel continues in a northerly direction passing through Pipestone Lake on its way to Cross Lake. The west channel flows out of the north ends of Playgreen Lake, Kiskittogisu Lake and Kiskitto Lake into Cross Lake at the Manitoba Hydro's Jenpeg Generating Station and Dam. From Cross Lake it flows through Sipiwesk Lake, Split Lake and Stephens Lake on its way to the Hudson Bay. Since it drains Lake Winni ...

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
