NKT signs $2.55B contract for UK's Eastern Green Link 3 transmission project

Danish power cable maker NKT has secured a significant $2.55 billion firm contract to supply the high-voltage direct current (HVDC) power cable system for the Eastern Green Link 3 (EGL3) transmission project in the United Kingdom. This substantial supply agreement involves the design, manufacture, and installation of a 525 kV HVDC power cable system stretching approximately 680 km, with a capacity of 2 GW. The project is a joint venture between two key UK transmission operators, National Grid Electricity Transmission and SSEN Transmission, underscoring its strategic importance for the nation's grid infrastructure. This deal is notable for its considerable value, representing a major win for NKT and a significant investment in the UK's energy backbone. The involvement of National Grid Electricity Transmission and SSEN Transmission, both primary owners and operators of the UK's high-voltage transmission networks, highlights the critical nature of the EGL3 project in enhancing grid capacity and reliability. The deployment of 525 kV HVDC technology over such a long distance signifies a commitment to advanced, efficient power transmission solutions capable of handling large capacities across the UK's diverse geography. The announced status of this firm contract, dated March 4, 2026, indicates a clear path forward for this essential infrastructure development.
