HVDC
SSEN Transmission and the Sumitomo Electric and Van Oord consortium have signed a long-term framework agreement to support the delivery of future high-voltage direct current (HVDC) subsea transmission infrastructure across northern Scotland.
This strategic partnership covers the engineering, supply, transportation, and installation of HVDC subsea cable systems, and includes the initial design and engineering work for the proposed 525 kV Shetland 2 HVDC link.
It combines SSEN Transmission’s long-term investment programme with Sumitomo Electric’s expertise in HVDC cable manufacturing and system design and Van Oord’s knowledge of offshore transport and installation.
Together, the businesses aim to support the delivery of the subsea transmission infrastructure required to modernise and expand Scotland’s electricity network.
The proposed Shetland 2 HVDC link between Shetland and mainland Scotland is expected to be one of the first projects progressed under the framework. It will help to increase network capacity, strengthen system resilience, and support the integration of renewable electricity into the wider UK energy system.
“As the energy transition accelerates, investment in offshore transmission infrastructure is becoming increasingly important to connect renewable energy to the electricity grid. This framework agreement brings together leading expertise across the HVDC value chain and establishes a strong foundation for long-term collaboration. It also reflects Van Oord’s long-standing commitment to the UK, where we have been active for over a century, working closely with local partners and supply chains to create lasting value. Together with SSEN Transmission and Sumitomo Electric, we are well positioned to deliver the critical infrastructure needed to support the UK’s energy transition,” said Maurits den Broeder, Managing Director,” said Maurits den Broeder, Managing Director Offshore Energy at Van Oord.
As renewable energy capacity continues to expand, offshore transmission infrastructure is essential. Through this collaboration, Van Oord will help deliver offshore energy and subsea power cable projects, supporting the resilient electricity networks needed for the energy transition.
