  1. Costreduction offshore windATO/We@Sea conferenceErnst van Zuijlen / Chris Westra6 december 2012

  2. Target of the TKI • Costreductionby 2020 O&M Costs COSTS YearlyCosts WACC Depreciation COSTPRICE Finance / risk Levelisedcosts / kWh Capital 40% OUTPUT 1/ Yearly Output Gross Output Losses COSTS COSTPRICE

  3. Target • Levelised costs offshore wind at € 100 / MWh 2010: 166 €/MWh 2020: 99 €/MWh

  4. Actual average Capex (per MW) dssdsdsd adapted from Greenacre et al. (2010).

  5. Further cost increases • Planning and consent procedure • Building and operational Risk • Experiences (grout, gear boxes......) • Perception of risk • Lack of standardisation • Further at sea, deeper water

  6. Bigger, deeper, further

  7. UK findings (cost reduction; 1) • Larger turbines with higher reliability and energy capture and lower operating costs. • Increased competition in key supply markets

  8. Innovative turbines Norwegian Sway 10MW offshore wind turbine, the ST10. The company claimed an estimated 15-20% reduction in turbine cost, and a considerable reduction in cost per kWh produced.

  9. UK findings (cost reduction; 2) • Economies of scale and standardisation (mass produced deeper water foundations. • Optimisation of installation methods. • Wind farm design en supplier involvement • Reduced WACC!!

  10. The Dutch approach • R&D: TKI / FLOW / we@sea programme

  11. Project Leeghwater • A demonstration / pilot plant PILOT PLANT ~100 MW About 8 consortia x 2 installations @ 6 MW DEMONSTRATION FARM ~200 MW • Various consortiafor test projectswithin the pilot plant • (BOOT)

  12. Dutch cost reduction policy options Measures to be taken by the government: • Socialisation of the offshore grid • Long term stable policy • Optimised regulatory framework • Risk sharing (finance) • More space available close to the shore(Hollandsekust)

  13. Spatial planning Hollandse Kust concept concept Aanwijzing HK en TNW (2 Nautical miles (NM) and 5 NM from platforms) ( 500 meter from shipning lanes Option with minimal space Option with maximal space 2 oktober 2012

  14. NL Translation UK findings (Ecofys) • All efforts needed: • R&D • Demonstration • Market development • Socialisation of grid costs • Policy optimisation • Reduction of finance costs

  15. A leading role for the Dutch? • Support structures • Transport, Installation & Logistics • O&M • Project development • Port facilities

  16. Dutch contributions XEMC-DarwinD 2B-Energy Of de DOT: “Delft Offshore Turbine”?

  17. Dutch contributions • Smart scour protection

  18. Dutch contributions • Transfer systems for personnel and “small” components

  19. Dutch contributions • Slip joint • (no grout, no transition piece)

  20. Dutch contributions • Integrated design of foundation and tower
