Oneinoperation;oneinthecommissionphase;Co-location/MUPnotimplemented
The stakeholders are not willing take new risks from Co-location/MUP; The risks related tothe aquaculture technology at the site; no financial supports for the Co-location/MUP.

Inpre-projectphase(difficulttoreachfullinvestmentdecision)
Co-location/MUP will increase the total yield and has the potential to improve theeconomics; The implementation bottlenecks are the maturity of the aquaculture technologyat the site and financial supports for combining both wind and aquaculture sectors

Inpre-projectphase(nearfullinvestmentdecision)
Proposed in 2006; The investment decision was postponed for 10 years due to the maturityof the floating wind turbine technology and the emission reduction benefits.

Inoperationphase The Co-location (150 MW wind and aquaculture at small scale) is in operation. Feedbacksfrom the stakeholders are excellent; Co-location and MUP are included in the design of thesecond 150 MW offshorewind farm.

Inpre-projectphase The stakeholders requested the Co-location/MUP; The low risk aquaculture activities basedon the local traditions were implanted in the feasibility study.
