Spirit Of Ireland
Spirit of Ireland is a proposal to build pumped-storage hydroelectricity reservoirs in valleys in Ireland's west coast combined with large-scale on-shore and off-shore windfarms to reduce Ireland's dependence on imported energy and fossil fuels. It would initially involve identifying up to five coastal valleys from counties Donegal to Cork, building dams on their seaward side and flooding them with sea water. These would provide a hydro-power back-up for the wind farms. The proposal has been likened to the construction of the Ardnacrusha hydroelectric power scheme, which was Ireland's first large post-independence infrastructure project and required investment equivalent to 25% of the national budget at the time but met the majority of the state's electricity needs for 50 years. The project came about when the two founders of the Pumped Hydro Electric Company (Dermot McDonald and Mark Wheeler) met Igor Shvets, a physics professor at Trinity College Dublin and Graham O'Donnell. ...

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Turlough Hill
Turlough Hill (), also known as Tomaneena (), is a mountain in County Wicklow in Ireland and site of Ireland's only pumped-storage hydroelectricity plant. The power station is owned and operated by the ESB and can generate up to of electricity at times of peak demand. The mountain The historian Liam Price recorded that the mountain was known locally as Tomaneena; Turlough Hill is the name given to it by the ESB when they surveyed the site for the pumped-storage scheme. It is high and is the 136th highest summit in Ireland. The summit is located to the south-west of the upper reservoir and is easily reached via the tarmac access road that begins at the top of the Wicklow Gap. It is also possible to reach the summit from Glendalough or from the summits of neighbouring Camaderry and Conavalla mountains. The underlying geology of the mountain is granite, covered with blanket bog, which is a habitat for heather, purple moor grass and moss. A number of alpine plants grow ne ...

European Super Grid
The European super grid is a possible future super grid that would ultimately interconnect the various European countries and the regions around Europe's borders – including North Africa, Kazakhstan, and Turkey – with a high-voltage direct current (HVDC) power grid. It is envisaged that a European super grid would: * lower the cost of power in all participating countries by allowing the entire region to share the most efficient power plants; * pool load variability and power station unreliability, reducing the margin of inefficient spinning reserve and standby that have to be supplied; * allow for wider use of renewable energy, particularly wind energy, from the concept that "it is always windy somewhere" – in particular it tends to be windy in the summer in North Africa, and windy in the winter in Europe; * allow wide sharing of the total European hydro power resource, which is about 6 weeks of full load European output; * decrease Europe's dependence on im ...

Celtic Interconnector
The Celtic Interconnector is a planned 700 MW high-voltage direct current (HVDC) submarine power cable between the southern coast of Ireland and the north-west coast of France. If completed as planned, it will be the first such interconnector between the two countries. The director general of EirGrid stated in 2022 that the interconnector was arguably "the most important Irish infrastructure project for this decade". Route The cable is due to run between the Knockraha substation in County Cork to the La Martyre substation in Finistère. Of its total length of , will pass through Irish, British and French waters of the Celtic Sea. Status On 14 Sept 2022, the UK Marine Management Organisation granted a licence for the project to proceed. This was the last major license required before Step 6 construction could start in late 2022. Project step six, construction and energisation, is scheduled to take place from 2022 to 2026. As of November 2022, the interconnector was "due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Interconnector
An interconnector (also known as a DC tie in the USA) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids. They can be formed of submarine power cables or underground power cables or overhead power lines. The longest interconnection as of July 2022 was the 2,210 km Hami - Zhengzhou delivering 8 GW of high voltage direct current power. The longest proposed connector is the 3,800 km, 3.6 GW Xlinks Morocco-UK Power Project. Economy Interconnectors allow the trading of electricity between territories. For example, the East–West Interconnector allows the trading of electricity between the UK and Ireland. A territory which generates more energy than it requires for its own activities can therefore sell surplus energy to a neighbouring territory. Interconnectors also provide increased resilience.

Wind Power In The Republic Of Ireland
The island of Ireland has 5,585 megawatt and the Republic of Ireland has 4,309 MW of installed wind power nameplate capacity, the third highest per capita in the world. In 2020 wind turbines generated 36.3% of Ireland's electrical demand, one of the highest wind power penetrations in the world. Ireland has over 300 wind farms (nearly 400 all-island); mostly onshore, with only the 25 MW Arklow Bank Wind Park situated offshore as of 2020. This is unlike Germany and Great Britain two other European countries with high wind power penetration whose territorial waters (particularly the German Bight and waters off the coast of Scotland) are in extensive and growing use for offshore wind power. Ireland's instantaneous wind power generation fluctuates between near zero and nearly 4,500 MW due to weather, with an average capacity factor of 32.3% in 2015. Irish wind power generation is higher during winter and lower in the summer. The overall capacity factor of Irish wind farms is hi ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam A dam is a barrier that stops or restricts the flow of surface water or underground streams ...

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.
