REpower and RWE Innogy agree EUR 2bn framework agreement for supply of offshore wind turbines

20 February 2009 – REpower Systems and RWE Innogy have signed a framework agreement on the supply of 250 REpower 5M/6M offshore wind energy units.

With a potential volume of approximately EUR2bn ($2.5bn) this framework agreement represents one of the largest contracts in the history of wind industry and is at the same time the largest agreement ever in the area of offshore wind energy use.

The first 30 offshore wind energy units of the REpower 5M model are scheduled to be delivered in 2011, and the delivery volume will continue to rise through the years 2012 to 2015.

The units will for the most part be used in the planned Innogy Nordsee 1 wind farm, which will be built 40 kilometres to the north of the East Frisian island of Juist. Due to the distance, the wind farm will not be visible from the coast.

Kevin McCullough, Chief Operating Officer of RWE Innogy, reports: “Innogy Nordsee 1 is an extremely exciting project. 40 kilometres north of the island of Juist, we are planning to construct between 150 and 180 wind turbines of the 5 and 6 megawatt class at water depths of 26 to 34 meters.

“With an installed capacity of around 1000 MW, the wind farm will statistically be able to supply electricity to around 780 000 households. The agreement allows for significant flexibility across the full range of our offshore projects under development, including important markets like the Netherlands and the UK.”

With a nominal output of 5 and 6 megawatts and a rotor diameter of 126 meters, the 5M and 6M are among the largest and most powerful wind energy systems in the world.

The rotor consists of three rotor blades of 61.5 meters in length and has an area greater than that of two football fields, while the turbine house has the dimensions of a semi-detached house.

REpower is currently installing the first three machines of the 6M series in an onshore project on the border to Denmark.
