12 Offshore wind power projects: now and tomorrow Lillgrund Wind Farm 48 wind turbines (110MW) Water depths: 4-13 m Distance to shore: 6-7 km Sheringham Shoal Wind Farm 88 wind turbines (316.8 MW) Water depths: m Distance to shore: 23 km Dan Tysk Wind Farm 80 wind turbines (288 MW) Water depths: m Distance to shore: 70 km Page 12

13 Challenges in the offshore business Optimize technology for larger projects, farther offshore Optimize installation technology and secure vessels REDUCE LCOE Industrialize logistics Apply experience gained to new markets Page 13

14 Why focus on LCOE? Subsidies won t last forever Page 14 Siemens AG 2011

15 We need to reach wholesale parity sooner Business as usual scenario Siemens strategy Historical scenario: -40% per decade. > 15 years to reach wholesale parity Target: -40% in less than a decade. < 10 years to reach wholesale parity LCOE [ct / kwh] LCOE [ct / kwh] Baseload energy price Baseload energy price Note: Past and planned LCOE development of SWP s portfolio Page 15

16 Content Offshore Experience Offshore Challenges Siemens Solutions Page 16

17 Levelised Cost of Energy CAPEX + Other CAPEX Lifecycle energy output + OPEX = LCOE Reduce Capital Expenditures (CAPEX) (e.g. lower weight, less components) Reduce other CAPEX outside Siemens scope (e.g.: offshore foundations) Reduce Operating Costs (OPEX) (e.g.: lower maintenance though higher reliability) Increase lifecycle energy output (e.g. higher efficiency, higher life time) Page 17

18 Technology is driving down LCOE Making wind power competitive Innovations to drive down costs Direct Drive LCOE [ct / kwh] Quantum Blade Efficient Level of Production 25 years Design Lifetime Page 18

19 Direct Drive: Contributing to lower LCOE Innovation The Siemens Direct Drive design incorporates a permanent magnet generator that makes gearboxes redundant Available as 2.3, 3.0 and 6.0 MW turbine Advantages 50 % fewer parts Significantly less rotating mechanisms Permanent magnet excitation Compact, easy to handle, simplified and lightweight design Direct Drive Benefits Higher energy production High strength efficiency by minimal energy loss even at low wind speed higher energy yield Reduced complexity leads to lower costs for installation, services and maintenance Easier to transport and install Page 19

20 SWT : The Next Generation of Turbine Direct Drive and Proven Rotor Technology Direct Drive wind turbine with 6 MW rated power and a 120/154 m rotor diameter designed specifically for the harsh offshore environment Simple and straightforward design based on and benefiting from experience with smaller Siemens Direct Drive turbines Tower head mass less than 350 tons a new low-weight standard for offshore turbines. This will contribute significantly to reduced cost of offshore wind energy, including Balance of Plant Prototype installation Høvsøre, Denmark Page 20

21 Optimized production processes means faster project delivery WTG Factory Road Transport. Sea Transport. Installation & Commissioning Handed to customer SWT-6.0 Factory Port Sea Transport. Installation & Commissioning Handed to customer Hub assembly and modular nacelle design next to port Avoidance of heavy road transport limitations Power unit and transformer in the nacelle allows for entire electrical system to be tested onshore ( precommissioning ) Better quality and early troubleshooting Minimized offshore time: - Faster delivery and lower costs - Higher safety for personnel - Less weather uncertainty Page 21

22 Highly Accelerated Lifetime Testing simulating 25 years of operation to ensure a high quality product The Siemens Wind Power SWT-6.0 test program Rotor Structure Performance Tests programs performed: Blade tests Blade bearing tests Pitch tests Tests programs performed: Main bearing tests Back-to-Back tests Vibration tests Tests programs performed: Low load tests Performance tests Page 22

23 Quantum Blades: Contributing to lower LCOE Innovation Unique airfoils, redesigned tip and root sections Siemens flatback profiles Produced in IntegralBlades process Advantages Excellent weight-length ratio Minimal root leakage and higher lift Moulded in one single production step from fiberglass-reinforced epoxy resin Optimal acoustic performance Quantum Blade Benefits Higher energy yield at low to medium wind speeds High strength and reliability at low weight no glued joints 20% weight reduction Higher performance with lower noise Page 23

24 25 Year Design Lifetime: Contributing to lower LCOE Innovation The Siemens Direct Drive design incorporated with 5 years additional design lifetime enables more energy production Advantages Same product design as the Direct Drive machines, scaled to fit the 25 years design life time 25 years Design Lifetime Benefits 25 % more energy production over the product lifetime Lower LCOE Page 24

25 Another way to deal with challenges: Partnering up on all important areas Offshore sites in deeper waters and at a larger distance to the shore need new technology Turbine technology: We partner with major players to develop new technical solutions New grid solutions like HVDC plus: Together with the Siemens Energy Transmission Division, we offer integrated solutions for grid connections Installation vessels: We partner with vessel design companies to ensure solutions for the future Technology and equipment for the more challenging sites will be ready early in the next decade, but large investments are required!

26 Strategic alliances Developing the offshore industry Creating synergy by working closely with our customers Alliances with long-term partners like DONG Energy and Scottish Southern Energy Strategic alliance with DONG Energy through A2SEA Optimizing processes to enhance customer value, increase efficiency and shorten installation times Page 26

27 The World s first floating turbine Hywind Cooperation on technology with Statoil to develop World's first floating offshore installation In 2009 Siemens installed the first turbine in Norway at a water depth of about 220 meters Floating offshore turbines could be installed at sites with greater water depths Reduced visual impact and increased power production due to strong and stable wind conditions Page 27

28 In what way are we prepared for the challenges that will come Due to a mixture of motives, Siemens is able to handle the challenges of the offshore future Experience Reliability Collaboration Innovation Service Page 28
