5 Benefits of Offshore Wind Power...sustainability 7 months until positive energy balance is reached (on average an offshore wind farm redeems the energy input for fabrication, transport and installation after this period) 100% CO 2 -free power generation (even taking into account manufactoring, transport, installation and maintenance, CO 2 emissions are only 7-12g CO 2 /kwh) high level of reliability 97% availability and better More than 2 decades of operation have already been sucessfully completed by Siemens offshore wind power plants more steady yields 100% more full-load hours (offshore, with more than 4,000 operating hours annually at full load possible) Offshore wind power means higher expenditures, but also wide acceptance higher yield Markedly higher yield per turbine Typical annual yields Inland Coastal (onshore) Offshore 2.3 MW turbine 7 GWh 9 GWh 3.6 MW turbine 12 GWh 18 GWh 6.0 MW turbine 23 GWh 31 GWh enormous potential 80% more capacity (wind turbines with a total output of 30 gigawatts (GW) currently installed in Germany, further 25 gigawatts offshore planned by 2030) Page 5 September 20, 2012 Siemens AG

8 Ambitious offshore objectives in the UK The largest offshore market today is Great Britain. Rapid and sharp expansion of offshore wind power is planned. Great Britain 1.2 gigawatts (Round 1 completed) 7.2 gigawatts (Round 2 ongoing) 2.0 gigawatts (Expans. 1&2 ongoing) 32.0 gigawatts (Round 3 planned) 6.0 gigawatts (Scotland planned) 48.4 gigawatts 25% Offshore share of energy mix by 2020 Page 8 September 20, 2012 Siemens AG

9 Case Study: London Array Location Page 9 September 20, 2012 Siemens AG

10 London Array the world s largest offshore wind power plant Phase One: 175 Siemens wind turbines with a capacity of 3.6MW each, 120-meter rotor and a hub height of 87 meters above sea level. Two offshore substations and an onshore substation. Rated at 630 MW once operational Could generate enough energy to power over 470,000 homes and displace over 900,000 tonnes of CO 2 a year equivalent to taking nearly 300,000 cars off the road each year. Siemens will also provide a warranty and five year turbine servicing contract. Phase Two: Expansion to a capacity of up to 1 GW Developed by DONG Energy, E.ON and Masdar Page 10 September 20, 2012 Siemens AG

11 London Array key milestones Project start date onshore construction at Cleve Hill started in July 2009 Offshore construction started in March 2011 when the first foundation was installed First turbine erected end of January 2012 First power expected this autumn All turbines of Phase One installed by end of 2012 End of August 2012: all monopiles are installed Page 11 September 20, 2012 Siemens AG

12 Cost effectiveness of wind technology: Where is the potential for optimization? Rotor blades Determine energy yield Nacelle and drive train Smart design increases reliability and efficiency Tower Height is essential for wind capture Project management, transport & Installation Important cost factor Balance of plant (BoP) Important share of infrastructure and overall project costs Service Important for availability Page 12 September 20, 2012 Siemens AG

13 Getting the costs of energy down - Innovations Example 1: The world s largest rotor blade B75 Increased rotor-swept area harvests more wind and is thus crucial for the annual energy yield of the turbine. IntegralBlade-Technology: the world's largest fiberglass component cast in one piece. No seams or glued joints and no adhesive, all of which saves weight. Page 13 September 20, 2012 Siemens AG

14 Getting the costs of energy down - Innovations Example 2: Nacelle Direct Drive Technology Gearless drive train increases reliability and availability 50% less parts reduces maintenance time 30% less weight facilitates installations offshore Higher energy yield Page 14 September 20, 2012 Siemens AG

15 Getting the costs of energy down - Innovations Example 3: 6 MW offshore gearless wind turbine 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 Towerhead mass less than 350 tons a new lowweight standard for offshore turbines. This will contribute significantly to reduced cost of offshore wind energy, including Balance of Plant Turbine design optimized for offshore installation and commissioning High emphasis on safe and comfortable working environment, and cost effective service and maintenance Prototype installation Høvsøre, Denmark Page 15 September 20, 2012 Siemens AG

16 Getting the costs of energy down further levers: Industrialization By introducing line production for nacelles, the production time was reduced by more than 50%, from 36 hours to 15 hours. Another way to lower the cost of energy is to produce a larger of number of wind turbines. Page 16 September 20, 2012 Siemens AG

17 Getting the costs of energy down further levers: Synergies with maritime industry Strategic Partners Partnership with A2SEA Siemens as equity partner: DONG 51%, Siemens 49% A2SEA is a small/medium-sized company based in Fredericia (DK) A2SEA provides installation services for offshore wind farms Reduces installation times and costs to execute offshore projects Strong commitment to the future of the offshore wind industry Page 17 September 20, 2012 Siemens AG
