Italian cable manufacturer Prysmian has signed a major contract for the delivery of the Eastern Green Link 4 (EGL4) electrical interconnector project with UK transmission owners SP Energy Networks and National Grid Electricity Transmission plc.
The agreement, valued at more than €2.3 billion, will be added to Prysmian’s project backlog. The company had previously been named preferred bidder for the project in September 2025, paving the way for the formal contract award.
Eastern Green Link 4 is a new high-voltage direct current (HVDC) subsea and onshore cable connection that will link Fife in Scotland with Norfolk in England. Designed to transmit up to 2GW of renewable electricity, the interconnector is expected to deliver enough clean energy to supply approximately two million homes. It forms part of a broader portfolio of five similar projects aimed at significantly expanding transmission capacity between Scotland and England.
Company leadership highlighted that the UK has positioned itself at the forefront of modernising electricity infrastructure by investing in undersea HVDC technology to transport renewable power efficiently across long distances. The project reflects a strategic approach that is increasingly being adopted by other countries seeking to futureproof their energy systems.
Prysmian has already been involved in several major HVDC developments in the UK, strengthening its role in supporting the country’s energy transition. With EGL4, the company further consolidates its presence in one of Europe’s most dynamic transmission markets, contributing to the delivery of large-scale renewable energy to homes and businesses in a cost-effective and time-efficient manner.
