Need for long term policy – Phased development offshore wind in Netherlands

Short Term (to

2023)

Three phase (parallel) development:

➢ North Sea Wind Power Hub ➢ Far-reaching international

cooperation necessary

Medium Term (to

2030)

Long Term (to

2050)

➢ Currently under development (near shore)

➢ Use full potential near shore locations ➢ Prepare for large scale and international

cooperation

How to deal with further increase of offshore wind

31


How to deal with further increase of offshore wind – grid optimization

32

The development and integration in the electricity system of large scale offshore wind energy requires knowledge, experience

and high investments in the onshore grids


Research and innovation needs – DNV GL participates in Europe’s PROMOTioN project with over 30 partners

▪ PROMOTioN Progress on meshed offshore transmission networks – European research will prepare next

generation technologies on HVDC addressing following challenges:

35

=~

– Offshore requires cables & platforms

– Long cables require HVDC

– HVDC requires converters

– HVDC network requires HVDC control & protection

system

– HVDC protection system requires HVDC switchgear

/ circuit breakers

– Transnational network

o Regulatory differences

o Business models

o Governance

o Financing


Summary

▪ Stress in offshore supply chains

▪ Grid extensions onshore - optimization

▪ Research and innovation needs like PROMOTioN

▪ Risk mitigation and reduction

– Power system studies

– Technology qualification, 3rd party review, and verification

– Certification, e.g. DNVGL-SE-0190 Certification of wind power plants

▪ Establish good long-term planning processes, especially for energy scenarios and grid

infrastructure to ensure that energy transition becomes a success

– Stable environment for investors, operators, all stakeholders
