New directions for new energy

The world of energy is becoming increasingly complex: growing energy demand is being met by ever more energy sources. These provide us with more and more challenges, ranging from generation via distribution to grid control. Factors such as technologies, the general public, markets, distribution, digitalisation and networks determine deadlines, processes and costs. Our focus is on wind energy, network growth and decommissioning, on and off shore, national and international.

North Sea East wind farm

The wind farm was built by RWE Innogy in the German Exclusive Economic Zone of the North Sea with 48 wind turbines.

Gemini wind farm

The wind farm is located in the Dutch Exclusive Economic Zone in the south of the North Sea. It consists of two parts, each with 75 wind turbines. With a total output of 600MW, it was one of the biggest offshore wind farms in the world when it became operational in April 2017.  

North Sea One wind farm

The wind farm is located in the German Exclusive Economic Zone in the North Sea, and should come into operational service in 2017.  Northland Power is the majority owner with an 85% share.

Hohe See wind farm

The wind farm is a planned offshore wind farm from EnBW (Energie Baden-Würtemmburg) with an installed capacity of 497MW. 71 wind turbines each with a nominal capacity of 7MW should be built.   

 

HVDC platform BorWin 2 & 3

An 800 and a 900 megawatt strong direct current connection  was realised by TenneT in the project BorWin 2 & 3. In the future different wind farms situated more than 100 km from the coast can use this to feed large quantities of wind generated electricity into the grid.

HVDC platform DolWin 2 & 3

An 800, a 916 and a 900 megawatt strong direct current connection was realised by TenneT in the projects DolWin1, 2 & 3. In the future different wind farms situated more than 100 km from the coast can use this to feed large quantities of wind generated electricity into the grid.

HVDC platform HelWin 1 & 2

A 576 and a 690 megawatt strong direct current connection was realised by TenneT in the project HelWin1, 2 & 3 realisiert. In the future different wind farms situated more than 100 km from the coast can use this to feed large quantities of wind generated electricity into the grid.

HVDC platform IFA2

A 240 km long 1,000MW HVDC between Southampton in England and the Normandy in France is being realised by RTE/National Grid in the project “Interconnexion France Angleterre 2”. The pipieline will contribute to grid stability between the British Isles and mainland Europe.

HVDC platform DolWin 6

A 90km long 900MW HDVC between a converter station in Hilgenriedersiel, Germany and an offshore convertor platform 45km from the coast is being realised by TenneT Offshore GmbH in the project “DolWin6“. The offshore convertor platform DolWin converts AC into DC which is then transported to the mainland in a 45km long underwater cable.  Tennet is constructing a convertor station and a substation nearby to convert the DC back into AC and to feed it into the grid.  

Distribution grid Conneforde-Cloppenburg-Merzen

The new pipeline Conneforde-Cloppenburg-Merzen brings electricity which the onshore wind turbines produce in the North to the South to the consumers. The project is making an important contribution in connecting the offshore wind farms. 

Distribution grid SuedOstLink

The project SuedOstLink  is being planned and implemented jointly by the transmission network operators 50Hertz and TenneT. SuedOstLink is currently in the planning phase.

Onshore/Offshore Distribution grid NordLink

NordLink is being realised as an HVDC between Germany and Norway with a route length of 623km. The convertor stations are being constructed in Wilster and Tonstad. 

West coast pipeline

This onshore project is being realised with a new route and has the target of increasing the transmission capacity between Germany and Denmark. The cosntruction of the west coast pipleine is necessary because the existing grid in Schleswig-Holstein has reached its limit.

 

GUD Kraftwerk Malženice

Kraftwerk Malženice ist ein im Betrieb befindliches Gas-und-Dampf-Kombikraftwerk in der Slowakei. Seit Ende 2008 wurde in 26 Monaten am Standort einer alten Gasverdichterstation des Gasversorgers SPP ein Kraftwerk durch E.ON gebaut. Das Kraftwerk hat im Kombibetrieb eine elektrische Leistung von etwa 430 MW brutto bzw. 417 MW netto.

CCGT power station Gönyü Hungary
