The latest award further strengthens Balfour’s foothold in the booming electricity transmission market as network operators accelerate investment to connect a new generation of renewable energy projects.

The two-year deal, awarded through SSEN’s Accelerated Strategic Transmission Investment Offshore Framework, follows Balfour’s appointment last year to carry out enabling works at the site.

The contractor will deliver major earthworks and civil engineering infrastructure for the hub, including five platforms to accommodate two substations and three converter stations, alongside an operations base and supporting facilities.

More than 800 workers will be employed at peak construction, with Balfour committing to ensure at least 5% of the workforce comprises apprentices and graduates.

Philip Hoare, group chief executive at Balfour Beatty, said: “The Netherton Hub will play a pivotal role in enabling the delivery of secure, homegrown, low-carbon power at scale.”
