Offshore Study Conclusions

1. Incremental Network development possible

2. Meshed network is optimum

3. Offshore/Onshore network are symbiotic

4. Interconnectors will optimally develop both from shore and offshore

5. Smart grid devices enhance network flexibility and minimise scale of

offshore network (c.25%)

6. Reinforcements onshore consistent to proposals i.e. GRID25, Gate 3

North Seas Countries’ Offshore Grid Initiative (NSCOGI)

• NSCOGI MoU signed by 10 countries: Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Norway, Sweden and the UK

• NSCOGI will offer “a framework for regional cooperation to find common solutions to questions related to current and possible future grid infrastructure developments in the North Seas”
