3 E.ON is building one of the world s largest offshore wind farms in Denmark Rödsand 2 In spring 2009, E.ON commenced construction of Rödsand 2, south of the island of Lolland in Denmark. The wind farm, which is expected to be completed in autumn 2010, will be located three kilometres west of Nysted Havmöllepark (Nysted Wind Farm). Rödsand 2 comprises 90 wind turbines with a collective output of 207 megawatts and will produce 800 million kwh per year and supply electricity to 200,000 households. Rödsand 2 will replace power from coal-fired plants and thus reduce carbon dioxide emissions by 700,000 tonnes per year in the Nordic electricity system. Rödsand 2 will be constructed between Nysted Havmöllepark, Gedser and Rödby in southern Denmark on a 34 square kilometre area. The site office during construction is Rödby harbor. The wind turbines will be shipped from Nyborg to the wind farm. The concrete foundations will be produced in Poland and towed from there on barges directly to the offshore construction site. The 115 meter high wind turbines will be located in five rows with 18 wind turbines per row. A total of 75 kilometres of cable from the wind turbines will be connected to the transformer station, which is also offshore. E.ON is responsible for the wind turbines, foundations and the offshore grid system. Energinet.dk is responsible for the transformer station and the grid connection to land.

4 Rödby harbor Nysted Rödsand Gedser Nysted Havmöllepark Impact of Rödsand 2 on the environment During construction, the immediate environment around the farm will be impacted. There will be a certain amount of noise and the ocean floor will be affected when the foundation is being put in place and when cables are being laid. E.ON will investigate the environmental impact during the entire construction phase and environmental management is an important part of the Rödsand 2 project. A continuous and open dialogue will be held with the Danish authorities pertaining to the project. When the wind turbines have been commissioned, they will emit certain sounds and vibrations into the immediate surroundings. Noise calculations are based on the environmental investigations and have shown that levels are far below the noise limits. During the construction period, a 500 meter safety zone will be marked with yellow buoys around the area and sailing inside this area will not be permitted for safety reasons. When the wind farm has been completed, sailing through the farm will be allowed but it will not be permitted to dock or access the wind turbines or the transformer station. Photo: Steen E. Jensen

5 Energy for the future Wind power is currently the most rapidly growing renewable source of energy in the world. While carbon dioxide emissions are the most serious threat ever to the global climate, wind power produces zero emissions. Consequently, environmentally friendly wind power is a highly prioritized energy source worldwide. Denmark is world-leading in wind power utilization. Already today, nearly one quarter of Danish electricity is derived from wind power (23 percent). In 30 years, nearly 50 percent of all electricity in Denmark will be produced by wind farms. Per capita, Denmark is the world leader in terms of electricity generated from wind. And since wind power replaces coal-fired power, the current levels of environmentally hazardous emissions in Denmark have been reduced by 30 percent. Naturally, a wind turbine must be constructed where it can harness the most wind at sea. An offshore wind farm will produce 50 percent more electricity than one based onshore. Nysted Havmöllepark, which was formerly the world s largest offshore wind farm, has been in operation since 2003 outside Lolland. It is 20 percent owned by E.ON. Nysted comprises 72 turbines with a total output of 165 megawatts, which jointly produce 600 million kwh and supply electricity to 140,000 households. The facility is expected to: Cost approximately 450 million Have an output of 207 MW distributed among 90 turbines Produce 800 GWh per year Supply 200,000 homes with electricity Reduce carbon dioxide emissions by 700,000 tonnes per year
