Recommendation 42

42 Acknowledged

New guidance on inter-array wake effects (EN-3) lacks clarity for industry.

Conclusion
The concerns that we have heard from industry about the Government’s proposed new guidance on inter-array wake effects in EN-3 suggest that this may not have provided the clarity that was intended. This may especially be the case in relation to whether projects might be expected to damage their own business cases when taking “all reasonable steps to minimise” wake effects “as far as possible”. (Conclusion, Paragraph 100)
Government Response Summary
The government acknowledges the committee's concerns about the clarity of guidance on inter-array wake effects and notes that views on mitigation vary across the offshore wind sector, indicating no industry consensus.
Government Response Acknowledged
HM Government Acknowledged
We acknowledge the Committee’s concerns and recognise that views on mitigating wake effects vary across the offshore wind sector. The perspective shared with the Committee reflects some developers’ views but not an industry consensus. Our discussions with a broad range of developers suggest general agreement that mitigating wake effects is challenging without reducing overall energy output.
