2 THE NORTH SEA IS AN OLD ENERGY SOURCE

3 CURRENT STATUS NATURAL GAS IN NL 452 gas fields discovered (on- & offshore) 265 in production 4 converted to gas storage 62 depleted 30 planned for production 77 stranded fields 148 platforms on the Northsea Current reserves: 1090 BCM (25 jr) Of which ~779 BCM still in Groningen Onshore: 144 bcm Offshore: 167 bcm Infrastructure (platforms and pipelines) are at maximum and will decline from now on! Decommissioning has started in the North Sea

4 OFFSHORE PIPELINE GRID ~4000 km pipelines 4 major trunklines (WGT, NGT, Local, Nogat) 4 gas treatment facilities (Den Helder, Uithuizen) Full capacity not used anymore and in decline NOGAT trunckline up to the Doggers bank area Nearby future wind parks in central North Sea Future of pipeline grid is uncertain (OSPAR) Several sections of the offshore grid will become obsolete soon Potential for re-use (CO2, H2)? 4 System Integration Offshore Energy 19 December 2016

5 FUTURE GAS PRODUCTION FROM SMALL FIELDS The Netherlands will become import dependent Offshore production until 2040 Excluding Groningen field

6 FUTURE DECOMMISSIONING OF OFFSHORE INFRASTRUCTURE In a business as usual scenario (EBN 2016) Offshore Production will stop around 2050 outliers 26 January 2016

7 THE INDUSTRY IS PREPARING FOR DECOMMISSIONING High societal cost (72% public share) End of life (Economic or Technical)? Eliminate options for re-use or re-purpose Impact on ecology from removal? Pioneering Spirit 7 System Integration Offshore Energy 26 January 2016

8 DEVELOPMENT OF A NEW OFFSHORE ENERGY INFRASTRUCTURE High societal cost (offshore grid/subsidy) Spatial limitations offshore Grid connections and transport onshore Power balancing challenges Increasing maintenance cost far offshore 8 System Integration Offshore Energy Wind farm transformer station 26 January 2016

9 INTENSIVE USE NORTH SEA LEAVES LITTLE SPACE Offshore Oil & Gas Offshore Wind Offshore Infrastructure Excluded zones

10 VISION: FROM SEGREGATION TO INTEGRATION In need of clean power How to balance peak power? Is there a potential for integration and re-use of gas infrastructure for offshore wind? COOPERATION IN THE NORTH SEA REGION

System Integration in Offshore Energy

24 KEY SUCCESS FACTORS FOR SYSTEM INTEGRATION Can it be made economic? Does it fit in space and time? Is the technology mature? Does the legislation allow it? Are stakeholders aligned and committed? Is there public acceptance? Is there an environmental benefit? 25 System Integration Offshore Energy 26 January 2016
