2 Agenda Introduction CCV Fleet Ice Management Concept Challenges Turbine protection IOM De-Icing 2

3 Introduction Sweden 1st Installation in 2013 Alaska, USA 1st Installation in 2012 Minnesota, USA 1st Installation in 2012 Quebec, Canada 1st Installation in 2009 Czech Republic 1st Installation in 2008 Inner Mongolia, China 1st Installation in 2007 Ontario, Canada 1st Installation in 2013 Cold Climate Version (CCV) wind turbines installed since 2009 in North America Already more than 560 MW in operation under icing and cold climate Senvion has gained extensive know-how in wind turbines behavior and operation under icing events and keeps on investing to further improve and optimize 3

4 Cold Climate Management Concept Dedicated CCV design Avoids health and safety risks Ensures reliable turbine operation over wide range of temperature De-Icing/Anti-Icing System Minimizes downtime, the losses and the aerodynamic degradation Ice operation mode Avoids excessive loads and ensures mechanical integrity of the wind turbine operating under icing conditions 4

5 Agenda Introduction Challenges Ice Management Concept Turbine protection IOM De-Icing 5

6 Types of Challenges 6

7 Getting to the turbine 7

8 Projectile 8

9 Now you have to deal with that 9

10 Ice on the Blades?? 10

11 Ultrasonic is working 11

12 Agenda Introduction Challenges Ice Management Concept Turbine protection IOM De-Icing 12

13 WEC operation optimization Assessment of ice Testing Ice Detectors Measure vibration of the rotor Temperature monitoring on the blade Transponder RFID antennas Ice Detection based on observations State of the art Ice detection based on the wind turbine s parameters: - Temperature - Wind speed reading deviation between heated and unheated sensors - Deviation between theoretical and actual power output 13

14 WEC operation optimization Understanding and optimization of icing loads Operational Impact On Site Observation Icing Classification Light icing Medium icing Severe icing Slight aerodynamic degradation Normal Operation Mode of the WEC Natural aerodynamic degradation WEC operated under Ice Operation Mode (safe and optimized operation through pitch and tip speed control) 14

15 WEC operation optimization Maximization of yield software-based features to combine risk mitigation and yield optimization: Time-based switching capabilities Risk Class I - No impact of ice throw Risk Class II - High impact of ice throw Additional loads & performance degradation H&S related impact Ice Operation Mode turbine keeps operating Turbine Stops in case of ice detection 15

16 Agenda Introduction Challenges Ice Management Concept Turbine protection IOM De-Icing 16

17 WEC operation optimization Maximization of yield De-icing system adapted to cold climate conditions Several years of experience in de-icing systems Minimizes turbine shut down and aerodynamic degradation by offering De-icing system to remove the ice accumulation on blades (automated or manual mode) Anti-icing system to prevent the ice accumulation on blades Ice Detection or manual activation Heating the Air Guiding the air Wind turbine operation 17

18 Agenda Introduction Challenges Ice Management Concept Turbine protection IOM De-Icing Conclusion 18

19 Conclusion On the right track and as we continue to operate in these cold conditions we will find new and better solutions to reduce the operational risks and improve WEC efficiency 19
