The BEIS Offshore Transmission Network Review

The BEIS (Department for Business, Energy and Industrial Strategy) Offshore Transmission Network Review

A specific objective of the SEAS campaign has been to call for a Review of offshore wind transmission infrastructure. Finally, in July 2020, the hundreds of SEAS letters and postcards sent to the Secretary of State combined with our growing advocacy and media pressure paid off and a Review was called; the Offshore Transmission Network Review.

In October 2021, BEIS published its latest Newsletter Update.  

SEAS will continue to feed into this Review, campaigning for the Secretary of State to include EA1N, EA2 and now Nautilus Interconnector within the meaningful objectives and outcomes of this Review.

National Grid Electricity System Operator also published their final Phase 1 report on Offshore Coordination in December 2020 , which highlighted the benefits of a more coordinated approach to offshore transmission. BUT, in this report, Sizewell is their name for Friston and it is designated for mass industrialisation, the central Hub for the region. We are in favour of integrated solutions. But we continue to oppose their site selection because there are better brownfield or industrialised sites using advanced HVDC technology.

Campaign With Us

We are asking you to write, to the Secretary of State for the Department of Business, Energy and Industrial Strategy (BEIS), The Rt Hon Kwasi Kwarteng MP, calling for him to reconsider a 'split decision' so that:

  1. The offshore turbines are recommended for consent.
  2. The onshore infrastructure is rejected in favour of full consideration of better locations for this infrastructure where the adverse impacts are minimised at a brownfield or industrialised site.
