Chair: Lena Kitzing, SP8 Coordinator

The objective of this session was to explore and share knowledge amongst participants about three important focus areas of the sub-program topic, spanning some of the great variety of sub-topics. The following presentations were given:

  • Deployment considerations for HVDC Meshed Offshore Grids in the Northern Seas – John Moore, Tenne
  • Social impacts as part of environmental impact assessments for wind farms? Challenges and recommendations – David Philipp Rudolph, DTU
  • Repowering and its economic implications: today and in the future – Lena Kitzing, DTU
    The PROMOTioN project is a large EU H2020 funded project that investigates all issues related to meshed offshore grids in the

North Sea, including technical, governmental, financial, economic, market, legal and regulatory issues. The project follows to parallel paths to a deployment plan, moving from analysis of topologies and technological choices to cost-benefit analyses on the one side, and from legal and regulatory and governmental questions to the design of market structures for meshed grids. The project identified issues and needs, and there is still much development to do on the economic, regulatory and market side to bring meshed offshore grids to reality.

In the IEA Wind Task 28, our EERA member developed guidelines on how to constructively address social impacts as part of the Environmental Impact Assessment (EIA) process, leading to increased acceptances of RE projects, increased community engagement and better dialogue, the possibility to explore, develop and nurture positive impacts and to exercise better support for decision-makers. The recommendations for future EIAs are to 1. Include social impacts in scoping; 2. Conduct a social baseline study; 3. Include social impacts at planning level; 4. Focus on local benefits; 5. Start with citizens; 6. Acknowledge and reduce uncertainty; 7. Describe the whole project; 8. Create transparency on pros and cons; 9. Strengthen public participation; 10. Develop a joint communication plan; 11. Improve non-technical summary.

Related to work undertaken in the IEA Wind Task 26, our EERA member presented ongoing work on an analysis on repowering of onshore wind energy in Denmark, where the scope of the repowering definition was broadened to include all decommissioned turbines that had to be dismantled in order to enable to new projects, regardless of spatial or chronical proximity to the new turbines. Quite surprisingly, it is very common to see turbines taken down due to diverse reasons, including far reaching noise effects, aesthetics, and political reasons.

The session included many questions to the presenters and a lively discussion about the core subjects in the sub-programme: economic, planning and social issues of offshore and onshore wind energy projects.
