Whitegate Power Station
Whitegate power station is a 445 MW combined cycle gas turbine (CCGT) electricity generating station near Whitegate, County Cork in Ireland. It was commissioned in 2010 and can supply up to ten percent of the electricity demand in Ireland. History In 2005 the then ESB Eirgrid identified that additional electricity generating capacity would be required by 2010. In response Bord Gáis Éireann (now Bord Gáis Energy), a commercial state body, proposed to build a new power station in County Cork. A site was selected (51°49’07”N 08°15’17”W) adjacent to Whitegate refinery, this provided ready access to light distillate from the refinery for use as fuel. It was also close to the natural gas grid and to the electricity grid at the 110 kV high voltage Whitegate substation. Bord Gáis contracted General Electric Operations and Maintenance (GE O&M) to design, operate and maintain the power station. Construction started in March 2008. The investment in the station was ...

Whitegate Refinery
The Whitegate refinery, near Whitegate, County Cork, is Ireland's only oil refinery. It has a capacity of 75,000 Barrel (unit), barrels of oil per day (bpd), sufficient to provide 40 percent of Ireland's fuel requirements. It was commissioned in 1959 and was redeveloped several times and produces a range of petroleum products. History In the late 1950s, the Government of Ireland wished to develop industry in the country. A consortium of oil companies formed the Irish Refining Company Limited to construct and operate a refinery; the participant companies and their interests were Esso (40%), Shell-Mex & BP (40%) and Caltex (20%). The refinery was constructed on a 330-acre (133 ha) site at Whitegate, East Cork, County Cork. It was built over the period 1957 to 1959 at a cost of about £12.5 million. The refinery was commissioned in April 1959 with Esso as the operator. In 1965 the refinery was expanded to increase the capacity from 1.9 million tons per year to 2.5 million tons per ...

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] |

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

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 ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...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] |
Energy In Ireland
Ireland is a net energy importer. Ireland's import dependency decreased to 85% in 2014 (from 89% in 2013). The cost of all energy imports to Ireland was approximately €5.7 billion, down from €6.5 billion (revised) in 2013 due mainly to falling oil and, to a lesser extent, gas import prices. Consumption of all fuels fell in 2014 with the exception of peat, renewables and non-renewable wastes. Final consumption of electricity in 2017 was 26 TWh, a 1.1% increase on the previous year. Renewable electricity generation, consisting of wind, hydro, landfill gas, biomass and biogas, accounted for 30.1% of gross electricity consumption. In 2019, it was 31 TWh with renewables accounting for 37.6% of consumption. Energy-related emissions decreased by 2.1% in 2017 to a level 17% above 1990 levels. Energy-related emissions were 18% below 2005 levels. 60% of Irish greenhouse gas emissions are caused by energy consumption. Historical Data Electricity Final consumption of el ...

Electricity Sector In Ireland
The electricity sectors of the Republic of Ireland and Northern Ireland are integrated and supply 2.5 million customers from a combination of coal, peat, natural gas, wind and hydropower. In 2018 natural gas produced 51.8%, while wind turbines generated 28.1%, coal 7%, and peat 6.8% of Ireland's average electricity demand. In 2020 wind turbines generated 36.3% of Ireland's electrical demand, one of the highest wind power proportions in the world. While the United Kingdom was one of the first countries in the world to deploy commercial nuclear power plants, the island of Ireland has never had a nuclear power plant built on either side of the Irish border. Nuclear power in Ireland was discussed in the 1960s and 1970s but ultimately never phased in, with legislation now in place explicitly forbidding its introduction. The grid runs as a synchronous electrical grid and in terms of interconnections has undersea DC-only connections to the UK National Grid, alongside plans in the advanc ...
