UK, London: The Secretary of State for Energy Security and Net Zero has approved National Grid’s development consent order application for the Bramford to Twinstead Reinforcement, after an independent panel recommended that the application be approved. Three rounds of public consultation have taken place since 2021 to help shape the proposals, which will see around 27 km of existing overhead line removed and replaced with new overhead line and underground cables in the Dedham Vale National Landscape and the Stour Valley.
The plans include supporting construction, maintenance, and operational infrastructure. Strengthening the network in this way resolves a capacity bottleneck and will help deliver clear energy to where it is needed.
Project Director James Greenhalgh commented: “We are delighted that the Secretary of State has granted our application for development consent in line with the recommendation by the Planning Inspectorate. The Bramford to Twinstead Reinforcement is a vital project to address an existing constraint on the network that will help connect clean and low carbon energy to homes and businesses across the UK. The electricity transmission network in the east of England was built in the 1960s and needs significant upgrades to ensure that new sources of energy, such as offshore wind and nuclear, can be accommodated.”
Pre-construction survey work is underway at various locations along the project route, prior to the planned start of major construction activity in the first half of 2025. Construction work is continuing at the grid supply point (GSP) substation site between Butler’s Wood and Waldegrave Wood, where the first supergrid transformer was successfully delivered to site this year.
Balfour Beatty will be the main works contractor, while Murphy is delivering the GSP substation. The Estimated Cost of Completion for the Bramford to Twinstead Reinforcement is roughly £700 million.
