Balfour Beatty awarded Hinkley cabling works contract for National Grid

8 August 2018


Balfour Beatty, the international infrastructure group, has been awarded the ‘Hinkley 400kV Cable Works (Mendips)’ contract by National Grid plc as part of the ‘National Grid Underground Cable Framework’. The cabling works will form a critical part of the Hinkley Point C (HPC) connection scheme, which will connect the new HPC reactor to the national grid.

The contract involves the design, supply and construction of a new 8.5km long 400kV double circuit cable route from Loxton in the Mendip Hills to a new substation at Sandford; and, includes the construction of a new cable sealing end compound at Loxton to be completed ahead of commissioning of the first reactor unit in 2025.

The HPC connection scheme represents a major infrastructure project for the UK and in securing the contract Balfour Beatty demonstrated an ability to meet all of the planning requirements laid out in the Development Consent Order which formed a major part of the National Grid’s assessment criteria required for a project of this stature.

Mark Bullock, Balfour Beatty’s Chief Executive Officer for Rail and Utilities said, “This award builds on Balfour Beatty’s deepening relationship with National Grid and demonstrates our ability to deliver a combined specialist cabling and civils package to ensure that the Hinkley Point C connection works are delivered on time to secure the future energy requirements of the UK.”

Enabling works have already commenced with the project employing around 90 people at project peak including a graduate and two apprentices.
