The current approach to designing and building offshore transmission was developed when offshore wind was a nascent sector, and industry expectations were as low as 10GW by 2030. However, in the context of increasingly ambitious targets, constructing individual point to point connections for each offshore wind farm may not provide the most efficient approach, and could become a major barrier to delivery given the considerable environmental and local impacts, particularly from the associated onshore infrastructure required to connect to the national transmission network.

The OFTO workstream have published two papers, setting out the long- and short-term parameters that they consider need to be addressed to mitigate the grid transmission barriers to deployment and the timescales required to enable 2030 targets.


In July 2020 the Department for Business, Energy and Industrial Strategy (BEIS) launched a review to ensure that offshore transmission infrastructure is delivered in the most appropriate way, considering the increased ambition for offshore wind to achieve net zero. The review will seek to achieve the right balance between economic, social and environmental costs.


To deliver the review, BEIS has established a Project Board and Working Group, bringing together the key organisations involved in the timing, siting, design and delivery of offshore wind. The working group will assess the outputs from the various review workstreams and provide recommendations to the project board, which will consider how these should be taken forward by the respective organisations. To ensure the outputs of the workstreams are robust, and to support the delivery of a deliverable offshore regime, the offshore wind industry council (OWIC)and BEIS, are establishing an expert advisory group to test and challenge the assumptions and draft recommendations of the review. The expert advisory group will provide formal advice to the working group, which meets monthly to discuss the progress of the review.  It will be chaired by the Offshore Wind Industry Council and supported by BEIS.


We are inviting expressions of interest from individuals who wish to join the group, to:

  • provide input and expertise

  • assess the progress being made and

  • review the outputs

We are looking for a broad range of industry parties to take part including:

  • offshore wind and interconnector developers

  • offshore transmission owners

  • transmission owners

  • independent experts

  • environmental and consumer groups

Members of the expert advisory group will be expected to represent their industry/sector, not their organisations.


Applications for the Expert Advisory Group are now closed, and applicants will be notified of the outcome shortly.
