Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to construct grid connections for Sizewell C.

The policy position outlined in the National Energy System Operator (“NESO”) open letter [https://www.neso.energy/document/349496/download] (published 10^th December 2024) indicates that, given Sizewell C received planning consent in July 2022, the existing arrangements for Sizewell C grid connection should be eligible to be grandfathered, subject to NESO’s proposals for reforming the connections process being approved by Ofgem and taking effect.

National Grid Electricity Transmission has also confirmed that Sizewell C will retain the same enabling works identified in previous connection agreements (2007-2009).
