1 Wind Power & Renewables Division Market Unit Offshore Passion for Offshore - Frank Zimmermann, Head of Sales - 5 th British Chamber Conference on Renewable Energy, Hamburg, siemens.com/answers

2 Siemens Wind Power Offshore Passion in Numbers people working for offshore in our company 23 years of offshore experience 2,300 offshore turbines sold offshore turbines installed ~5.500 GW capacity) 2 modern product families for offshore classic and DD 20+ year proven product lifetime with >95% real availability Seite 2

3 Passion fosters Innovation and creates a New Industry From 30 kw to 6 MW in 30 years 79.8 meters 1980: 11 meters 1991: 35 meters 2012: 154 meters 30 kw 450 kw 6 MW Seite 3

4 However,. Markets Despite growth of market and turbine sizes, Offshore Wind continues to depend on incentive schemes. Cost of energy Positive effect of innovation and growth seems to be eaten up by increasingly complex projects. Customers Customer landscape changed in breathtaking speed from cash payers to financed investors. The industry needs to ensure a sustainable offshore market!!! How do we retain market leadership? How do we ensure a sustainable offshore market Seite 4

5 Our fundamental motivation for the development of future offshore wind turbines is reduction of LCoE Reduction of investment WTG investment BOP investment Reduction of O&M Cost Increase of energy output Seite 5

6 Offshore cost reduction is effective in multiple areas: reaching LCoE below 10 ct/kwh before 2020 Offshore CoE Targets, Wind farm level in cent/kwh % 17% % 14% 45% 16% % 5 cent/kwh % % Main levers per Cost Segment WTG ++ Industrialization Logistics improvements Installation & commissioning Foundation Simplified design, industrialized production Quayside completion 32% 24% 18% 28% 26% 18% 28% 26% Grid New cost efficient solutions Industrialized components OPEX Increased robustness Optimization of Setup Based on the SWT turbine; Offshore project 1.000MW Seite 6 Baseline 2014 WTG Cost out C-BOP Cost target 2020 E-BOP AEP increase OPEX (disc.) Target Cost 2020 AEP increase AEP (Annual Energy Production) Turbine upgrades Improved aerodynamics Increased availability

7 In 2020, wind turbines may look as today but will be very different Seite 7 Onshore Main Data Power rating: 2-4MW Rotor: m Hub heights: m Technologies Blades with structuralaerodynamic coupling for passive load reduction High-stiffness fibers in blades (carbon, new fiber types) Direct drive transmission Commoditized design, standard components Ancillary services, fault robust with short-term storage Main Data Power rating: 6-10MW Rotor: m Hub heights: m Technologies Offshore Basics same as onshore technologies Tailored redundancy concepts for increased robustness Two-year service intervals Electrical and civil infrastructure at 40% of today s cost Simplified installation w/o piling

8 Our baseline Siemens 6MW DD offshore turbine Blade 75 m, 25 t 20,000 knm moment (root) Hub Ø4.5 m, 40 t Generator Ø6.5 m, 100 t, 6-11 rpm 5,500 knm torque Bedplate 3.5 x 3.5 x 4 m, 25 t Power converter 2 x 3 MW, AC DC AC Transformer 7 MVA, 690 / 33,000 V Tower 100 m, ø4 m / ø6 m, 300 t Seite 8

9 Ideas beyond wind turbine improvement - e.g. today s Infrastructure design needs Innovation Seite 9

10 The radical idea to the platform challenge : Simply No platform! Concept: Platform with 300MVA 220/66kV transformer Transformer Deck Complete AC Booster Turbine Measurement and protection Turbine switch gear and distribution Array switch gear Cable hang-off Seite 10

11 Offshore Wind, Passion beyond clean energy generation Huge benefits for society Great potential for job creation Reduction of fossil fuel imports Huge export opportunities Nearly CO 2 -free power generation High level of reliability Seite 11
