NKT Emerges as Preferred Bidder for UK HVDC Interconnector

cable maker and services provider NKT has been selected as the preferred bidder to deliver the 525 kV high-voltage direct current (HVDC) power cable system for Eastern Green Link 3 (EGL3), a major interconnector project linking Scotland and England.The announcement was made by SSEN Transmission and National Grid Electricity Transmission, joint venture partners developing the 680-kilometer subsea and onshore cable link. The project is designed to strengthen Britain’s electricity backbone, boost system resilience, and help deliver more clean energy across the country.EGL3 is part of a broader UK
