Balfour Beatty has been awarded a £121 million, four-year contract by National Grid to deliver the Bramford 400kV substation extension in Suffolk, England, as part of the Bramford to Twinstead project.

Let under National Grid's EPC Framework, the scheme is a key element of the Great Grid Upgrade to expand and reinforce the UK's electricity transmission network.

Balfour Beatty will design and install the extension to enable four new circuits, including two new grid supply points, and add two new shunt reactors to improve network reliability and efficiency.

The company will also integrate new gantry structures to support overhead line connections, and design, supply and install critical systems to monitor, control and safeguard the network.

On completion, the upgrade will increase transmission capacity and strengthen resilience across the East Anglia electricity network, supporting the transition to a low carbon energy system.

Tony Wilson, Managing Director of Balfour Beatty's Power Transmission & Distribution business, said: "This latest award builds on our continued work across East Anglia to strengthen and modernise the UK's electricity network infrastructure.

"Our appointment reflects the expertise of our teams, our strong delivery track record and our capability to successfully deliver complex substation projects. We look forward to working closely with National Grid as we support increased network capacity and resilience for the communities and businesses that rely on this vital infrastructure."

Work is already under way, with completion expected in 2030. At peak, the project will employ around 150 people, including a number of apprentices and graduates.
