Thornhill Power Station
The Thornhill power station generated and supplied electricity to the town of Dewsbury and the wider regional area from 1902 to 1982, and again from 1998. The first generating station on the site was owned and operated by the Yorkshire Electric Power Company. Following nationalisation of the British electricity supply industry in 1948 Thornhill power station was operated by a succession of state owned bodies. The power station was redeveloped with new plant in 1915, 1925, 1932–37 and 1950–54. The coal-fired steam station was decommissioned in 1982, and was subsequently demolished. A gas turbine power station on the site was commissioned in 1998. History The Yorkshire Electric Power Company was established under the provisions of ''Yorkshire Electric Power Act 1901'' (1 Edw. 7 c. cxvi). A power station was built at Thornhill (53°40'38"N 1°39'17"W) on a site adjacent to the River Calder. The river provided water for cooling and condensing steam. It was also adjacent to a r ...

British Electricity Authority
The British Electricity Authority (BEA) was established as the central British electricity authority in 1948 under the nationalisation of Great Britain's electricity supply industry enacted by the Electricity Act 1947. The BEA was responsible for the generation, transmission and sale of electricity to area electricity boards, and the development and maintenance of an efficient, coordinated and economical system of electricity supply. History The authority took over the operations of over 600 small public supply power companies, municipal authority electricity departments and the Central Electricity Board to form the BEA, which comprised a central authority and 14 area boards. Its scope did not include control of the North of Scotland Hydro-Electric Board, which had been founded in 1943 and remained independent of the BEA. The appointment of chairmen and members of the BEA and the area boards were made in August 1947 and the BEA was formally established on 15 August 1947. The ...

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Cycle Power Plant
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Load Factor (electrical)
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load factor. f_ = \frac An example, using a large commercial electrical bill: * peak demand = * use = * number of days in billing cycle = Hence: * load factor = ( / / ) × 100% = 18.22% It can be derived from the load profile of the specific device or system of devices. Its value is always less than one because maximum demand is never lower than average demand, since facilities likely never operate at full capacity for the duration of an entire 24-hour day. A high load factor means power usage is relatively constant. Low load factor shows that occasionally a high demand is set. To service ...

Yorkshire Electricity
Yorkshire Electricity was an electricity distribution utility in England, serving much of Yorkshire and parts of Derbyshire, Lincolnshire and Nottinghamshire. History Formed as the Yorkshire Electricity Board in 1948 as part of the nationalisation of the electricity industry by the Electricity Act 1947. The establishment of the company involved the amalgamation of 50 private and local authority power companies. The Yorkshire Electricity Board took over Scarcroft Lodge in north Leeds as its headquarters. Nationalised industry The Yorkshire Electricity Board was responsible for the purchase of electricity from the electricity generator (the Central Electricity Generating Board from 1958) and its distribution and sale of electricity to customers. The key people on the board were chairman Arthur Bond (1964, 1967), deputy chairman R. H. M. Barkham (1964, 1967), and full-time member J. S. Yates (1964, 1967). The total number of customers supplied by the board was: The amount of el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nationalization
Nationalization (nationalisation in British English) is the process of transforming privately-owned assets into public assets by bringing them under the public ownership of a national government or state. Nationalization usually refers to private assets or to assets owned by lower levels of government (such as municipalities) being transferred to the state. Nationalization contrasts with privatization and with demutualization. When previously nationalized assets are privatized and subsequently returned to public ownership at a later stage, they are said to have undergone renationalization. Industries often subject to nationalization include the commanding heights of the economy – telecommunications, electric power, fossil fuels, railways, airlines, iron ore, media, postal services, banks, and water – though, in many jurisdictions, many such entities have no history of private ownership. Nationalization may occur with or without financial compensation to the former owners. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Grid (Great Britain)
In the electricity sector in the United Kingdom, the National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere on it can be used to satisfy demand elsewhere. The network covers the great majority of Great Britain and several of the surrounding islands. It does not cover Northern Ireland, which is part of a single electricity market with the Republic of Ireland. The GB grid is connected as a wide area synchronous grid nominally running at 50 hertz. There are also undersea interconnections to other grids in the Isle of Man, Northern Ireland, the Republic of Ireland, France, Belgium, the Netherlands and Norway. On the breakup of the Central Electricity Generating Board in 1990, the ownership and operation of the National Grid in England and Wales passed to National Grid Company plc, later to become National Grid Transco, and now National Grid plc.

Central Electricity Board
The United Kingdom Central Electricity Board (CEB) was established by the Electricity (Supply) Act 1926. It had the duty to supply electricity to authorised electricity undertakers, to determine which power stations would be 'selected' stations to generate electricity for the board, to provide main transmission lines to interconnect selected stations and electricity undertakers, and to standardise generating frequency. History In 1925 Lord Weir chaired a committee that proposed the creation of the Central Electricity Board to link the UK’s most efficient power stations with consumers via a ‘national gridiron’. At that time, the industry consisted of more than 600 electricity supply companies and local authority undertakings, and different areas operated at different voltages and frequencies (including DC in some places). The board's first chairman was Andrew Duncan. The CEB established the UK's first synchronised AC grid, running at 132 kilovolts and 50 Hertz, which ...
