Llynfi Power Station
Llynfi power station supplied electricity to the Bridgend area of Glamorgan South Wales from 1943 to 1977. The coal-fired station was originally built and operated by the South Wales Power Company Limited to supply electricity to munitions factories during the Second World War. It was completed by the post-nationalisation British Electricity Authority in 1951, and was later operated by the Central Electricity Generating Board. The power station was closed in 1977 and was subsequently demolished. There have been several proposals to redevelop the site. History Llanfi power station was built during the Second World War by the South Wales Power Company Limited. It was one of several power station built at this time, such as Birmingham Corporation’s Hams Hall B station, which the Electricity Commissioners and the Central Electricity Board were able to demonstrate were required to supply electricity to munitions factories. The South Wales Company also owned and operated Upper Boat p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cooling Tower
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to tall and in diameter, or rectangu ...

Bridgend County Borough Council
Bridgend County Borough Council ( cy, Cyngor Bwrdeistref Sirol Pen-y-bont ar Ogwr) is the governing body for Bridgend County Borough, one of the Principal Areas of Wales. History Bridgend County Borough and Bridgend County Borough Council came into effect from 1 April 1996, following the ''Local Government (Wales) Act 1994''. Bridgend County Borough Council largely replaced Ogwr Borough Council, though St Brides Major, Ewenny and Wick were transferred from Ogwr to the Vale of Glamorgan. In November 2014 the council voted to propose a merger with the neighbouring Vale of Glamorgan Council, though this was rejected by the Welsh Government's Public Services Minister, Leighton Andrews, as not meeting the criteria to be able to proceed. Political control The first election to the council was held in 1995, initially operating as a shadow authority before coming into its powers on 1 April 1996. Political control of the council since 1996 has been held by the following parties: Lea ... [...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 ...

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] |
SWALEC
SWALEC was an electricity supply and distribution company in South Wales, established in 1989 following the de-regulation of the electricity supply industry in the United Kingdom. The business has seen several changes of ownership from 1996, and the SWALEC brand has been used for retail gas supply as well as electricity. Today Western Power Distribution runs the distribution network business, and SWALEC Contracting is a trading name of OVO Energy. Predecessor The South Wales Electricity Board (SWEB) was formed in 1948 under the Electricity Act 1947, which brought about the nationalisation and merger of local authority and private electricity companies. The SWEB was responsible for the purchase of electricity from the electricity generator (the Central Electricity Generating Board from 1958) and the distribution and sale of electricity to customers. The key members of the Board were: Chairman W.D.D. Fenton (1964, 1967), Deputy Chairman H. Pryce-Jones (1964, 1967), full-time memb ...

Electricity Act 1947
The Electricity Act 1947 (10 & 11 Geo. 6. c. 54.) was an Act of the Parliament of the United Kingdom which nationalised, or bought into state control, the electricity supply industry in Great Britain. It established a central authority called the British Electricity Authority (BEA) to own and operate all public electricity generation and transmission facilities and created 14 area electricity boards with a duty to acquire bulk supplies of electricity from the central authority and to distribute and sell electricity economically and efficiently to industrial, commercial and domestic consumers. It vested 505 separate local authority and company owned electricity undertakings in the BEA with effect from 1 April 1948. The Electricity Act 1947 is one of a number of Acts promulgated by the post-war Labour government to nationalise elements of the UK’s industrial infrastructure; other Acts include the Coal Industry Nationalisation Act 1946; Transport Act 1947 (railways and long-dist ...

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] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Central Electricity Authority
The Central Electricity Authority (CEA) was a body that managed and operated the electricity supply industry in England and Wales between 1 April 1955 and 31 December 1957. The CEA replaced the earlier British Electricity Authority (BEA) as a result of the Electricity Reorganisation (Scotland) Act 1954, which moved responsibility for Scottish electricity supply to the Scottish Office. Structure The structure of the management board and the personnel in post remained the same as the BEA with the exception of the removal of representation by the chairman of the North of Scotland Hydro-Electric Board. There was a reduction from 14 to 12 of the number of area electricity boards – the South East Scotland Electricity Board and South West Scotland Electricity Board were removed from the CEA's management. The functions of the remaining area boards were unchanged. Upon its establishment in April 1955 the chairman of the CEA was Lord Citrine; the two deputy chairmen were Sir Henry ...
