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.

Butendiek wind farm

The construction of the wind farm with 80 Siemens SWT-3.6-120 wind turbines each with a nominal output of 3.6MW  started in Spring 2014 to the west of the island of Sylt. Full commissioning was completed in 2016.

Global Tech I wind farm

The wind farm was developed by Windreich. It comprises 80 wind turbines of the 5MW class. The plant became officially operational on 2nd September 2015.

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-Wuerttemberg) 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 pipeline 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 construction of the west coast pipeline is necessary because the existing grid in Schleswig-Holstein has reached its limit.


CCGT power station Malženice

Malženice power plant is a gas and steam combined cycle power plant in operation in Slovakia. Since the end of 2008, E.ON has built a power plant at the site of an old gas compressor station of the gas supplier SPP in 26 months. In combined operation, the power plant has an electrical output of approximately 430 MW gross and 417 MW net.

CCGT power station Gönyü Hungary

In Gönyü E.ON constructed a modern CCGT. The facility with a capacity of 400 MW has been on the grid since 2010. With an efficiency level of 58% Gönyü is one of the most efficient power plants in the world.
