UK-based construction firm Balfour Beatty has secured the £214m North and South 400kV overhead line project to connect the new Hinkley Point C nuclear power station to the national transmission network.

The contract, awarded via National Grid’s Overhead Line Design and Build Framework, represents key part of the Hinkley Point C (HPC) connection scheme. The overhead line project also marks Balfour Beatty’s third major package of works at HPC.

Pursuant to the contract, the construction firm will design, supply, install, test and commission a new overhead line spanning 48.4km and crossing through the Mendip Hills in Somerset, where Balfour Beatty is currently executing cable works under a separate contract for National Grid.

Work on the project is set to commence shortly, with completion expected in summer 2025. The project will employ a workforce of more than 150 people during peak construction period.

When completed, the new transmission line will connect HPC with a new substation in Avonmouth, Bristol.

Balfour Beatty stated that it will use National Grid’s new T-Pylon design, marking the first time this technology has been used on a live transmission asset.

Balfour Beatty CEO for its Rail and Utilities business Mark Bullock said: "Our extensive knowledge and unique capability in delivering major complex Overhead Line schemes, makes us ideally positioned to play a key role in helping to deliver the first nuclear power station to be built in the UK for more than 20 years.

"We look forward to working with National Grid to successfully and safely deliver low-carbon electricity for around six million homes across the UK."

Balfour Beatty is currently working on the projects, including the £47m Fort Augustus to Fort William 132kV Transmission Reinforcement project and the £43.5m Beauly to Keith 132kV Modernisation programme on behalf of Scottish Hydro Electric Transmission.

The company is also executing the £55m London Power Tunnels project for London Underground which will deliver a new 32km electrical superhighway in London and a €219m contract in a consortium with Prysmian Group to install a 65km electricity cable between France and Great Britain on behalf of ElecLink.
