Hitachi Energy has recently signed a successful bid for two large subsea cable link projects along Scotland’s coast. Siemens will provide planning, procurement, manufacturing, installation and commissioning for high-voltage direct current (HV DC) converter technology used in these projects. These projects are set to enhance the UK’s electricity transmission network and facilitate the nation’s transition to clean energy.
The first of the two builds an undersea cable to connect Spittal, Caithness, with Peterhead, Aberdeenshire. At the same time, the second of those projects would connect Scotland’s Western Isles to the Scottish mainland. Both initiatives are aimed at improving the UK and European grids. They will ensure that Scotland and Great Britain have a more reliable energy supply.
Details of the Projects
Like most subsea cable projects, the new links will feature converter stations at both ends to convert power between AC and DC. This infrastructure will transmit power quickly and seamlessly, while increasing our ability to export green energy generated from renewable resources.
The Western Isles link isn’t special—it’s unique. It will ultimately facilitate the seamless export of clean energy generated throughout the islands to the mainland grid and energy generation will eventually flow back to the islands themselves. Once completed, the Spittal-Peterhead link will be a vital, new energy corridor in northern Scotland. It will be extremely important to helping the region improve its energy security.
Planning permission has already been approved for the Lewis Hub (Stornoway) for the Western Isles project. Yet a separate application for the Fanellan converter station near Beauly remains pending before Highland Council. Assuming final approvals go through as planned, both projects are expected to be in full operation before 2030.
Commitment to Clean Energy Transition
Hitachi Energy’s role in these initiatives further showcases its role and responsibility in supporting the UK’s transition to clean energy. The company’s long-term goal is to make a major impact on the energy landscape, using its HV DC technology to do so.
Niklas Persson, a representative from Hitachi Energy, expressed pride in their role in these landmark projects:
“We are proud to contribute our HV DC technology to these landmark projects that will strengthen the UK’s transmission network and accelerate the energy transition.”
This parallel to national ambitions showcases Hitachi Energy’s commitment to maximising renewable energy potential throughout Scotland.
Strategic Importance of Infrastructure
This contract award marks an important milestone in creating the infrastructure we need to realise Scotland’s renewable energy potential. Sandy Mactaggart, commenting on the importance of these projects, stated:
“Today’s contract award marks another significant milestone in delivering the critical national 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.”
Taken together, all these initiatives hold great promise to improve energy security. They do it to foster new economic opportunities by enhancing regional connectivity and access to renewable energy resources.
