4 Our answer for advanced turbine technology: /120: The No. 1 offshore machine Main data: IEC Class: IA / IA* Rotor diameter: 107 / 120 m 350/394 Ft Blade length: 52 / 58,5 m 169/192 Ft Swept area: 9,000 / 11,300 m / Ft2 Hub height: Site specific Tower weight: Site specific Prototype installed: 2004 / 2009 Serial production: 2006 / 2010 First installed offshore: 2007 / 2011 Installed offshore: 275+ units * Target, certification process ongoing Page 4

5 -3.6 wind turbine General layout of -3.6 nacelle Offshore modifications Offshore modifications implemented as part of basic design. Modifications in place also for onshore turbines Arrangements generally according to principles having shown their worth from Vindeby onwards Transformer and HV switchgear in tower bottom Page 5

6 Our answer for advanced turbine technology: Integral Blade without glue joints Siemens Integral Blade The blade is manufactured in a single operation, using a closed process invented by Siemens No glue joints between spars and shells, no weak points, no easy access for water or lightning Combining superior strength with excellent power and noise performance Page 6

7 Our answer for advanced turbine technology: Continuous monitoring to prevent failures Turbine Condition Monitoring Designed to continuously monitor the external and internal state of the wind turbine 24 / 7 precise online vibration measurement on the gearbox, the generator and the main shaft bearings Detect significant deviations from its normal operating condition Prevention of costly breakdowns Reduced service costs Optimized availability and energy generation Page 7

8 Offshore wind is in a steep development phase 1990s 2000s # countries with offshore wind Avg. wind farm/project size 6 MW 90 MW >500 MW Avg. yearly installed capacity 3 MW 230 MW MW # significant manufacturers 2 3 >8 Avg. turbine size < 0.5 MW 3 MW 5-6 MW Avg. rotor diameter 37 m 98 m m Avg. water depth 5 m 15 m >30 m Customers Scandinavian utilities European utilities Global utilities, large consortia, non-utility investors Page 8

9 Bigger isn't always better 2.3 MW vs. 3.6 MW turbines at 15mph Smaller turbines more efficient in low winds Installed projects with 2.3 MW turbines Wind farm size 100MW 100MW Turbine type No. of turbines Average wind speed 15 mph 15 mph Annual Energy Production 342GWh/year 289 GWh/year The AEP at above example is 18% higher with the than with the ,00 160,00 140,00 120,00 Samsø, Denmark 10 x Rønland, Denmark 4 x Rødsand, Denmark 72 x Frederikshavn, Denmark 1 x Lillgrund, Sweden 48 x Hywind, Norway 1 x Horns Rev II, Denmark 91 x Power [kw] 100,00 80,00 60,00 40,00 20,00 0, ,00 Wind speed [m/s] Future projects: Baltic I, Germany 21 x Rødsand II, Denmark 90 x Page 9
