Cost Reduction Target [2]:
2013 2018
1. Foundation cost: 20% - 6% 14%
2. Installation cost: 25% - 7% 18%
3. Wind Turbine cost: 40% - 12% 28%
4. Grid Connection Cost: 15% - 4% 11%
Total: 100% 71%
Expected factors to help Driving costs downs [2]:
1. Scale economy
2. WT Power increase (Towards 10MW)
3. Innovation
4. Offshore experience and sector maturity
