Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what is Ofgem's estimated cost of the Sealink HVDC project.

National Grid Electricity Transmission (NGET) is developing proposals for Sea Link, a 2GW high voltage undersea electricity link between Suffolk and Kent. The project is forecast to cost NGET ~£1.1bn, as quantified by Ofgem in their ‘Decision on accelerating onshore electricity transmission investment’ paper published in December 2022. This cost estimate is based on a 2018/19 price base and is subject to final engineering design, commodity prices, landowner agreements and mitigation.
