IFA-2
IFA-2 (Interconnexion France-Angleterre 2) is a subsea electrical interconnector, running beneath the English Channel between France and the United Kingdom. The high voltage DC (HVDC) cable operates at +/-320kV with the capacity to transmit 1,000 MW of power. IFA-2 is the second interconnector built between France and Great Britain, after IFA (HVDC Cross-Channel) link. Route The cable connects to the French grid at the Tourbe 400kV substation. From there, a high voltage alternating current (HVAC) underground cable runs to the converter station nearby. A long underground HVDC cable runs from the converter station to the landfall point east of Merville-Franceville-Plage, near Caen in Normandy. On the British side, the landfall point is located at Monks Hill Beach, at the southern end of Solent Airfield, near Portsmouth. The converter station is located to the north east of Solent Airfield. From there, a long HVAC cable runs underwater to the point of connection to the gri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HVDC Cross-Channel
The HVDC Cross-Channel (french: Interconnexion France Angleterre IFA 2000) is the 73 km long high-voltage direct current (HVDC) interconnector that operates since 1986 under the English Channel between the continental European grid at Bonningues-lès-Calais and the British electricity grid at Sellindge. The cable is also known as IFA, and should not be confused with the new IFA-2, another interconnect with France that is three times as long but only half as powerful. The current 2,000MW link is bi-directional and the countries can import or export depending upon market demands, mostly depending upon weather conditions and availability of renewable energy on the British Isles, and French surplus of nuclear generation or demand for electric heating. It was completed in 1986, and replaced the first cross-Channel link which was a 160MW link completed in 1961 and decommissioned in 1984. A fire in September 2021 caused the link to be removed from service. National Grid announced that h ... [...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.

ElecLink
ElecLink is a 1000 MW HVDC electrical interconnector between the UK and France, passing through the Channel Tunnel. ElecLink commenced operations on 25 May 2022 following several delays due to safety concerns. Route The DC cable runs via the Channel Tunnel between converter stations at Peuplingues in France and Folkestone in the UK, with an additional of underground AC cable on the English side, and on the French side, to link the converter stations to the existing transmission networks. Ownership It is owned by a subsidiary of Getlink, which owns the tunnel itself. ElecLink is the first UK interconnector to be entirely funded by private finance, without being underwritten by electricity consumers. Construction The station was designed and installed primarily by Siemens AG and Siemens FIT (Field installation Team) with the help of Balfour Beatty, Galaghers, Mclaughlin & Harvey and many more. The contract for manufacturing the HVDC cables awarded to Prysmian. A spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RNAS Lee-on-Solent (HMS Daedalus)
Royal Naval Air Station Lee-on-Solent (HMS ''Daedalus'') was one of the primary shore airfields of the Fleet Air Arm. First established as a seaplane base in 1917 during the First World War, it later became the main training establishment and administrative centre of the Fleet Air Arm. Situated near Lee-on-the-Solent in Hampshire, approximately four miles west of Portsmouth on the coast of the Solent at , the airfield closed for military use in 1996 and passed through several owners until 2014 when the current owners Fareham Borough Council bought the airfield and re-branded as Solent Airport. The airfield hosts the Solent Enterprise Zone. History Naval aviation began at Lee-on-Solent on 30 July 1917 when the Royal Naval Air Service (RNAS) opened the Naval Seaplane Training School as an extension to the seaplane training station at nearby Calshot. The school's first commander was Squadron Commander Douglas Evill. Initially, aircraft had to be transported from their temporary ...
