Balfour Beatty has been awarded a £363m contract by National Grid to deliver the Bramford to Twinstead Reinforcement project.

Awarded through National Grid’s RIIO-2 framework, the project is intended to reinforce the electricity network in East Anglia, and ensure that it can continue to reliably and securely transport the cleaner, greener electricity required for the UK’s transition to net zero.

The company will be responsible for the replacement of the existing high voltage electricity network between Bramford Substation in Suffolk and Twinstead Tee in Essex, with a new 400 kilovolt overhead line spanning 18 kilometres.

In addition, Balfouor Beatty will also deliver 11 kilometres of underground cable through the Dedham Vale Area of Outstanding Natural Beauty and Stour Valley.

The project will involve working closely with ecologists and conservationists throughout to mitigate any disruption to local wildlife, and Balfour Beatty committed to delivering a 10% biodiversity net gain over the project lifecycle.

Leo Quinn, Balfour Beatty’s group chief executive, said: “This award demonstrates the momentum we are capturing in the energy security and transition market. As the largest power transmission provider in the UK, we have a long and proud history of working with National Grid.

“This latest award will once again enable our expert teams to deploy their proven capability to successfully deliver overhead lines and underground cabling works in complex and challenging landscapes.”

Main construction is expected to begin in the first half of 2025, with completion expected in 2028.
