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

Assessment 

In 2017 we carried out a Strategic Wider Works (SWW) Final Needs Case Assessment to consider whether we think there is a technical need for the project as designed. Our decision on this was published in January 2018.

In October 2019 we published a consultation on the capital costs that NGET should be allowed to recover from energy consumers for delivery of the project. We expect to publish a decision on this in early 2020.
