Wind Power Development in the Swiss alps

Transcription

1 Winterwind / 10. December 2008 Folkets park, Norrköping, Sweden Wind Power Development in the Swiss alps 10 years of experiences, lessons learned and new projects. Robert Horbaty, Managing Director Swiss Wind Energy Association Suisse Eole 1

2 Switzerland Wind Resources Konzept Wind Energy Switzerland : ca GWh 2

3 Electricity Supply in Switzerland 3

4 Why Wind Energy in Switzerland? Target is sustainable electricity supply Big Hydro is developed: new renewables are needed Wind Energy is a important mosaic stone to that Wind is the cheapest of all new renewables People want wind Green electricity market is growing There is a substantial potential in Switzerland: GWh Market for Swiss industry, planners and developers 4

5 Wind Energy: Swiss Industry IDS Zürich, 500 kw Generator with permanent magnets 80 % of turn over with wind energy 2007: 237 Mio CHF 5

6 Harsh Conditions? Icing on Lake Geneva, Switzerland! 6

7 Installed capacity 34 Turbines installed, Peak Power MWp, in 2007 (no new turbines) 15'946 MWh Energy yield, + 5 %! (Thanks to good winds) 7

8 Examples from Switzerland 7.66 MW Windpark Juvent SA im Berner Jura m.ü.m 30 kw Anlage auf dem Titlis, 3 000m.ü.M 8

9 Examples from Switzerland From the actual installation, only the wind turbine in Collonges (Enercon E-82) is not affected by rime, ice and cold temperatures 900 kw Nec-Micon Feldmoos, 1000m.a.s.l 9

10 Examples from Switzerland 150 kw Bonus, Grenchenberg 1 300m.a.s.l 600 kw Anlage auf dem Gütsch, m.ü.m 10

11 Development for incentive programs: Wind Energy Research Increase the availability and energy yield at extreme sites (cold climate, high turbulence intensity and difficult access). Development of wind turbine components for the application of this technology under specific Swiss conditions by Swiss industry Increase the value of wind energy (fore- and now-casting, regulating energy etc.) Increase the acceptance of wind energy ( Social Acceptance ) 11

12 Frequency of icing Of the located sites of the concept Wind Energy Switzerland, 90 % are in cold climatic regions 12

13 Research projects Site assessment under cold climatic conditions (Gotthard pass m a.s.l.) 13

14 Enercon E40, Mt. Gütsch m.a.s.l. 14

15 Alpine Wind Test Site 600 kw wind turbine Enercon E-40 test bench as a test station for ice detector COST727 action: Measuring and forecasting atmospheric icing structures 15

16 Results: 43 person from Germany, Switzerland, Austria, Italy 5 Turbine Manufacturer like Vestas,Enercon, Leitner 4 Instruments manufacturer 15 papers 16

17 Results of Work Shop: 43 person from Germany, Switzerland, Austria, Italy 5 Turbine Manufacturer like Vestas,Enercon, Leitner 4 Instruments manufacturer 15 papers 17

18 Blade repair on site 18

19 COST 727 and Gütsch Collecting samples of ice throw 19

20 Anti-freeze coating for rotorblades The Zurich University of Applied Studies is studying polymers with freezing point depression properties binding such polymers to surfaces testing anti-freeze coated surfaces Results in laboratory conditions: Reduction of freezing point up to 30 o C Development of final product in collaboration with wind power and Swiss polyester company 20
