Project Update

Richborough–Canterbury Transmission Line, UK [free access]

November 7, 2017

Developer: National Grid Electricity Transmission plc (NGET)


Project details and status: The project entails the construction of a new 20-km-long, 400 kV double-circuit overhead line (OHL) from Richborough to Canterbury and a new 400 kV substation in Richborough.


It also involves the removal of an existing 132 kV overhead line, for which the works will be undertaken between 2019 and 2021. The project is crucial for the realisation of the NEMO link—the first 1 GW high voltage direct current (HVDC) interconnector between Great Britain and Belgium—which will provide reliable and secure electricity supply in the region.

 In January 2016, NGET submitted its Development Consent Order (DCO) application to the Planning Inspectorate to build the 400 kV OHL. In February 2016, the Planning Inspectorate accepted its application for examination.


In October 2017, construction on the 400 kV line began after receiving approval from the Secretary of State for Business, Energy and Industrial Strategy in August 2017, after a lengthy consultation process, which sought the views of local landowners, tenants, the local community and other stakeholders.


 As reported, National Grid will soon start works at the Canterbury North and Richborough substations for the installation of new equipment, upgrade of existing technology, and extension of substation buildings.


 The line is expected to be operational by late 2018.
