SSEN Transmission has today [Tuesday 16 December] awarded global energy technology leader Hitachi Energy major contracts to deliver high-voltage direct current (HVDC) converter stations for two critical subsea transmission links — including the fully consented Spittal to Peterhead project, which will play a central role in unlocking the north of Scotland’s renewable energy potential.
This milestone builds on Hitachi Energy being selected as preferred bidder in 2023 and subsequently being appointed under a framework agreement designed to accelerate delivery of the UK’s clean-energy transition.
Contracts cover the initial design, supply-chain mobilisation, critical pre-construction steps and full convertor station build-out at Banniskirk (Spittal) in Caithness and at the Netherton Hub in Peterhead. Hitachi Energy will also deliver the HVDC Converter Technology for the proposed Western Isles connection.
This latest milestone on two of SSEN Transmission’s key projects in the north of Scotland demonstrate the commitment of the business to delivering meaningful social value alongside critical infrastructure. In November, SSEN Transmission became the first business to sign the Highland Social Value Charter, committing to a comprehensive set of socio-economic benefits for communities across the Highlands as part of its £22 billion+ investment programme. Under the Charter – which sets out expectations for infrastructure developers to maximise local economic opportunities and inclusive growth — SSEN Transmission has pledged to deliver significant local contracts, investment in roads and bridges, support for housing development, community benefit funding, a net gain in biodiversity and more.
Niklas Persson, Managing Director of Hitachi Energy´s Grid Integration business, said:
“We are proud to contribute our HVDC technology to these landmark projects that will strengthen the UK’s transmission network and accelerate the energy transition. Delivering reliable power at scale requires not only advanced solutions but also deep collaboration and shared commitment to strengthen the UK and European grids. Together with SSEN Transmission, we are shaping a future where clean power flows seamlessly across borders, accelerating progress toward a sustainable, carbon-neutral society for generations to come.”
The Spittal–Peterhead link, already fully consented with a marine licence granted, will form a new strategic transmission corridor across the north of Scotland – providing essential capacity to move clean electricity from Caithness, Orkney and Shetland southwards, while strengthening security of supply for communities in the north-east and across Great Britain. Construction activity is expected to start soon.
While the Western Isles link remains subject to final planning and marine consents, it continues to progress through regulatory and environmental processes. The Lewis Hub at Stornoway has now secured consent, with a planning application under consideration by Highland Council for the Fanellan converter station near Beauly, alongside a submitted marine licence application.
Hitachi Energy boasts a strong track record in delivering HVDC infrastructure globally, as well as delivery experience in the UK. With this contract award, the company and SSEN Transmission reaffirm their shared commitment to delivering on the UK’s clean-energy ambitions and laying the foundation for reliable, large-scale renewable power transmission across the country.
Sandy Mactaggart, SSEN Transmission’s Director of Offshore Delivery, said:
“Today’s contract award marks another significant milestone in delivering the critical infrastructure required to unlock Scotland’s renewable energy potential. The Western Isles and Spittal to Peterhead links will play a vital role in strengthening our network, enhancing security of supply and enabling the connection of home-grown clean energy for homes and businesses across the country.
“As the first business to sign the Highland Social Value Charter, we’re also committed to ensuring that projects like these deliver clear and lasting benefits for the communities who host them – from local job creation and skills development to wider economic and environmental improvements. We’re looking forward to continuing our close collaboration with Hitachi Energy as we progress these transformative projects and deliver the transmission system our clean energy future needs.”
Subject to the remaining approvals for the Western Isles link, both subsea projects are anticipated to be energised by 2030, providing essential capacity to transport clean, secure and affordable electricity across Scotland and to consumers throughout Great Britain.
