Eastern Green Link 4 has confirmed £3 billion in supply chain contract awards, including key agreements with Siemens Energy and Prysmian, as the UK transmission project moves closer to construction.
The project said Siemens Energy will provide high-voltage direct current (HVDC) converter stations, while Prysmian has secured a contract worth around £2 billion to supply both subsea and underground cables.
Eastern Green Link 4 is being developed as a joint venture between SP Energy Networks and National Grid Electricity Transmission. The planned 2GW link will extend approximately 640 kilometres between Scotland and England, enabling long-distance electricity transmission.
Converter stations are planned in Fife and Norfolk, where electricity will be converted between alternating current (AC) and direct current (DC) to facilitate efficient transmission along the route.
The project forms part of a broader programme of five subsea links along the UK’s east coast, aimed at strengthening grid resilience and supporting increased integration of renewable energy.
Construction is expected to begin in 2028, with completion targeted for 2033, subject to planning approvals.
“Confirming £3 billion of contract awards demonstrates the scale and momentum behind Eastern Green Link 4 as we move into delivery,” said James Goode, project director of Eastern Green Link 4.
“These agreements not only give us the confidence to progress at pace but also highlight how investment in network infrastructure can and will support UK economic growth, strengthen domestic capability and unlock the capacity needed to transport renewable energy efficiently, supporting both UK energy security and a cleaner energy system,” he added.
“Eastern Green Link 4 is a critical project for strengthening the UK’s electricity network and enabling more renewable power to flow between Scotland and England,” said Darren Davidson, UK vice president for Siemens Energy.
“With more than 7,000 people employed by Siemens Energy across the UK, including at our centre of excellence in Manchester, this project highlights how investment in grid infrastructure supports skilled jobs, energy security and the UK’s long-term transition to a more resilient energy system,” he added.
