Proven know-how in rotor blade design and manufacturing enables fast ramp-up of this key component. 250 AREVA M5000 turbines have been selected for use in European offshore wind parks. Most recently, the group installed and commissioned Alpha Ventus, Germany’s first offshore wind park.

Our new wind turbine in Hamburg is 40 metres higher than conventional ones. Since wind speed increases with every extra metre of height, this means 20 % more power. This 190-metre turbine is the highest of its kind anywhere in the world. 2,500 households are now benefi tting from clean, green power, and CO2 emissions have been cut by 3,100 tonnes a year.

Having agreed on the need to improve interconnections to integrate the energy market properly, and shore up the EU’s energy supply, ministers stated that in many Member States there are severe delays for building energy transmission and distribution infrastructure. These de- lays could be reduced by putting projects considered to be of European interest into a fast track system. Ministers also agreed that the market should fi nance energy infrastructure projects, and that this should be made easier by simplifying the administra- tive procedures.
