What is the 'Offshore Coordination Project'?

The Offshore Coordination Project has been set up by the ESO with support from Ofgem and the Department for Business, Energy & Industrial Strategy.

Offshore wind has been identified as a critical technology in achieving net zero greenhouse gas emissions by 2050. In order to help realise this target, a step-change in both the speed and scale of deployment of offshore wind is required. One of the challenges to delivering the ambition for offshore wind deployment in the timescales required will be ensuring that the offshore and onshore transmission network enables this growth in a way that is efficient for consumers and takes account of the impacts on communities and the environment.

The ESO offshore coordination project, which contributes to the OTNR, was set up in March 2020. Phase 1 of our project progressed at pace to assess the costs and benefits of a coordinated offshore network compared to the current radial approach, the technical considerations to achieve that, and how the offshore connections regime could change to drive greater coordination.

The scope of the second phase of the project was informed by responses to our consultation in October 2020, in which areas for further work were identified, and has evolved through discussions with BEIS, Ofgem and other stakeholders in order to ensure alignment with the OTNR.

Collaborating with stakeholders

We are working in collaboration with stakeholders on this important and fundamental piece of work for the energy industry, consumers, communities and the environment.

Our role in connecting offshore wind farms to the grid

Offshore wind farms are a key part of the government’s plans for the UK to be net zero in 2050. We don’t own any of the turbines, or the substations and cables that link them, so what’s our role in connecting them to the grid?
