Offshore wind power presentation for China

  1. 1. offshore wind power in Europe Chris Westra (senior consultant ECN) (general manager We@Sea) ) www.we-at-sea.org www.ECN.nl
  2. 2. Offshore wind energy 2010 - 2020 Great Britain , Netherlands, Germany, Belgium.
  3. 3. Europa (2) B: >4 GW DK: > 4 GW UK: > 33 GW NL: > 6 GW D: 25 GW x North Sea National targets 2030
  4. 4. Potential of the North Sea More energy than from the Middle East ! European offshore wind energy community
  5. 5. Policy <ul><li>Pan European (offshore grid) </li></ul><ul><li>Protection of marine eco-system </li></ul><ul><li>Spatial Planning </li></ul><ul><li>Support technology development </li></ul><ul><li>Create a level field electricity market </li></ul>Focal points for European Policy
  6. 6. Wind energy annual installation 2000-2020 (GW) Source: EWEA/GWEC Realise consequences of annually installing 5000 MW offshore !!! Potential
  7. 7. Offshore wind energy & Spatial planning In the Netherlands
  8. 8. Dutch offshore projects 228 MW OWEZ 108 MW, 2006 ( M€ 260) Princes Amalia 120 MW, 2007 ( M€ 380) 36 x Vestas 3MW V90  108 MW 10 – 18 km from the coast 18 m water depth Monopiles 30 m into seabed OWEZ
  9. 9. Princes Amalia wind farm 60 Vestas 2 MW V80  120 MW 23 km from coast 19 - 24 m water depth mono piles
  10. 10. Ambition of the Dutch neighbors at sea <ul><li>Germany: </li></ul><ul><li>1500 MW in 2011 and </li></ul><ul><li>25.000 MW in 2030. (Pilot Alpha Ventus) </li></ul><ul><li>United Kingdom: </li></ul><ul><li>At present 600 MW in operation </li></ul><ul><li>1500 MW under construction </li></ul><ul><li>‘ Round 3’: 25.000 MW </li></ul>
  11. 11. Onshore wind turbines modified for sea circumstances
  12. 12. Thanet the newest largest offshore wind farm Great Britain Round 2 (sept. 2010) <ul><li>100 turbines (Vestas V90) </li></ul><ul><li>3 MW  300 MW </li></ul><ul><li>3 Million Euro / MW </li></ul>

  29. 30. Artificial Island for construction and maintenance of offshore wind farms © Reinout Prins
  30. 31. Primary functions: <ul><li>harbour for construction and O&M of wind farms </li></ul><ul><li>site for offshore transformer station </li></ul><ul><li>hotel for personnel </li></ul><ul><li>test site offshore wind turbines </li></ul><ul><li>warehouse for spare parts </li></ul><ul><li>International logistic hub for offshore wind farms (NL, U.K. & DE) </li></ul>
  31. 32. Artificial islands fit well in the development of an European offshore grid
  32. 33. A closer look at port sites B: >4 GW DK: > 4 GW UK: > 33 GW NL: > 6 GW D: 25 GW
  33. 34. Islands as part of an offshore network (electrical infrastructure) “ North Clay-land” “ North-East Friesland” “ IJmuiden op zee”
  34. 36. A substation on a jacket and on an island the advantage of a substation on an island
  35. 37. Vision for the future <ul><li>Harbours to facilitate the large scale implementation of offshore wind energy at the North Sea </li></ul><ul><li>cooperating between NL, B, U.K. & DE to find strategic sites at the North Sea to build artificial islands for offshore wind power </li></ul><ul><li>contribute to the development of an European offshore electrical grid </li></ul>
