Grid connection study for world’s largest wind farm

1 April 2005 – The German wind farm developer at the helm of creating the world’s largest offshore wind farm has contracted Areva T&D to study the grid connection options for its final 4.5 GW capacity.

Under the contract awarded by GmbH & Co. KG, Areva will carry out a grid connection feasibility study and will consider different proposals for the pilot phase before deciding which would be the best option for the final 4.5 GW installation.

The three proposals under consideration are: high voltage alternating current connection, hybrid-high voltage direct current connection, and voltage source converter high voltage direct current connection.

The sandbank 24 project is located just of the German coast in the North Sea. The 360 to 400 MW pilot phase has already received planning permission and is due to start in 2006. The pilot phase will consist of 80 single wind turbine generators with a capacity of 4.5 to 5 MW each and will be connected to the electricity transmission network.
