Norwich to Tilbury is a Nationally Significant Infrastructure Project (NSIP) proposal being developed by National Grid Electricity Transmission (NGET), to build a new 400kV electricity transmission line between Norwich and Tilbury. The entire scheme is 179 kilometres (111 miles) in length and crosses parts of Norfolk, Suffolk, and Essex. The Suffolk section is 53 kilometres (33 miles in length) and crosses parts of Babergh and Mid Suffolk District Councils. The scheme also crosses the Dedham Vale Area of Outstanding Natural Beauty (Dedham Vale AONB) on the border with Essex.
Suffolk County Council is a statutory consultee, and a decision would ultimately be taken by the relevant Secretary of State, if an application for development consent is submitted.
The proposals have been subject to a non-statutory consultation, held by National Grid between the 21 April and 16 June 2022.
