List Of Thermal Power Station Failures
This list is concerned with severe and abnormal power outages which caused major power failures due to damage to a single thermal power station itself or its connections which take a significant amount of time - months or years to repair. Whilst any electric grid is vulnerable to instability after the loss of a large generating source or transmission line, this can generally be dealt with without serious inconvenience to customers. However some power stations can be exceptionally large in respect to connected grid capacity so that any failure for these proportionally large stations can be more problematic than the failure of a typically sized station.

Thermal Power Station
A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator. The low-pressure exhaust from the turbine enters a steam condenser where it is cooled to produce hot condensate which is recycled to the heating process to generate more high pressure steam. This is known as a Rankine cycle. The design of thermal power stations depends on the intended energy source: fossil fuel, nuclear and geothermal power, solar energy, biofuels, and waste incineration are all used. Certain thermal power stations are also designed to produce heat for industrial purposes; for district heating; or desalination of water, in addition to generating electrical power. Fuels such as natural gas or oil can also be burnt directly in gas turbines (internal combustion). These pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriel Power Station
Kriel Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. It is located about 4 km from Matla Power Station just outside the town of Kriel (Emalahleni Local Municipality, Mpumalanga). In contrast with most other Eskom power stations, the turbine generators at Kriel are each housed in a separate building rather than the more common single turbine hall. When Kriel was completed in 1979 it was the largest coal-fired power station in the Southern Hemisphere. It was also one of the first stations to be supplied with coal from a fully mechanised coal mine. History On 25 July 2022, the entire power station tripped. Eskom said the first fault caused units 1, 2 and 3 of the power station to trip, while the second fault tripped units 4 and 5. Unit 6 was already offline. Power generation The station has six 500MW units for a total installed capacity of 3,000MW with turbine Maximum Continuous Rating at 36.90%. See also * Fossil-fuel power pl ...

List Of Hydroelectric Power Station Failures
This is a list of major hydroelectric power station failures due to damage to a hydroelectric power station or its connections. Every generating station trips from time to time due to minor defects and can usually be restarted when the defect has been remedied. Various protections are built into the stations to cause shutdown before major damage is caused. Some hydroelectric power station failures may go beyond the immediate loss of generation capacity, including destruction of the turbine itself, reservoir breach and significant destruction of national grid infrastructure downstream. These can take years to remedy in some cases. Where a generating station is large compared to the connected grid capacity, any failure can cause extensive disruption within the network. A serious failure in a proportionally large hydroelectric generating station or its associated transmission line will remove a large block of power from the grid that may lead to widespread disturbances.

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Dam Failure
A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release. Between the years 2000 and 2009 more than 200 notable dam failures happened worldwide. A dam is a barrier across flowing water that obstructs, that directs or slows down the flow, often creating a reservoir, lake or impoundments. Most dams have a section called a ''spillway or weir'' over or through which water flows, either intermittently or continuously, and some have hydroelectricity, hydroelectric power generation systems installed. Dams are considered "installations containing dangerous forces" under International humanitarian law due to the massive impact of a possible destruction on the civilian population and the environment. Dam failures are comparatively rare, but can cause immense damage and loss of life when they occur. In 1975 the 1975 Banqiao Dam failure, failure of ...

They were charged with theft, fraud and corruption in connection with the disappearance of spares. It was further alleged that four persons operated an oil crime syndicate which had been stealing large amounts of fuel from the station, valued at hundreds of millions of rand. Mid-December 2022, at the request of the Minister of Public Enter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rooiwal Power Station
Rooiwal Power Station is a 300-megawatt (MW) coal-fired power plant near Pretoria in Gauteng, South Africa. Location A Google map at shows the location of the plant north of Pretoria, in the Mont Lorraine area of Tshwane Municipality, Gauteng. Background Rooiwal Power Station is a five-unit coal-fired power plant with a total capacity of 300 MW. The plant was completed between 1962 and 1970, and is owned by Tshwane Electricity Division. In April 2015 the City of Tshwane said it was seeking proposals to renovate two coal-fired power plants to their original design capacity: Pretoria West Power Station and Rooiwal Power Station. Both are operating considerably below their capacity partly because they have been designed to use anthracite, a grade of coal that is more profitable to export.

Medupi Power Station
Medupi Power Station is a dry-cooled coal-fired power station built by Eskom near Lephalale in Limpopo province, South Africa. The name chosen for the station, Medupi, is a Sepedi word which means "gentle rain". With an installed capacity of 4,764 MW, when fully operational it should be the 8th largest coal-fired power station in the world. Original concept Medupi was conceived as Project Alpha in 2007, with only three units planned to total 2,400 MW and estimated cost of R32 billion. The design was changed at a late stage in 2007 and doubled in size to 4,764 MW. The boilers were envisaged to be supercritical in type, which would make them 38% more effective than other Eskom power stations. A dry cooled system was also intended to use less water than other coal-fired power stations in the fleet. Initial project costing was estimated at R69 billion but that was updated to approximately R80 billion by 2007. Parsons Brinckerhoff was appointed as the project engineer to oversee al ...

Matla Power Station
Matla Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom and consuming the output from the Matla coal mine. History Construction started in 1974, and the last unit was commissioned in July 1983. In 1981 the southernmost smokestack measuring in height was demolished after it partially collapsed during construction, killing 4 workers. It held the world record for the tallest free standing structure to be explosively demolished for 24 years until the 2006 demolition of the Westerholt Power Station chimney. The actual explosion was also used in a gag in Jamie Uys' Funny People 2, where an electrician is instructed to do some wiring, and is warned that improper connection will cause the stack to explode.
