Hinkley Seabank

Hinkley Seabank is a proposed new transmission project to allow for the safe connection of the planned Hinkley Point C nuclear power station. The project will also provide additional capability and relieve transmission constraints in the South West of England. 

In January 2016 the Secretary of State for Energy and Climate Change approved National Grid’s plans for the project. These plans can be found on National Grid’s website

Needs Case Assessment 

In 2017 we will carry out a Strategic Wider Works Needs Case Assessment which will determine through consultation: 

  • Whether we think there is a technical need for the project as designed. 
  • Whether the project, or sections of it, are suitable for our extending competition in electricity transmission arrangements. 

We will also conduct a Strategic Wider Works Project Assessment which will determine the efficient costs that National Grid can recover from energy consumers for delivery of the project. 

Next steps

We plan to consult on our findings on the project's Needs Case in summer 2017.
