National Grid has awarded contracts worth £59B ($76.5B) to suppliers as part of its High Voltage Direct Current (HVDC) supply chain framework, aimed at enhancing the UK's energy infrastructure.

The framework, launched in 2023, establishes long-term agreements to secure critical equipment for ongoing and future energy projects. The contracts cover HVDC cable supply ($27.6B) and HVDC converter systems ($31.9B).

Six suppliers have secured positions on the HVDC cable framework: Hellenic & Jan De Nul Consortium, LS Cable & System, NKT Cables, Prysmian Group, Sumitomo Electric, and Taihan Cable & Solution. The HVDC converter systems framework has been awarded to GE Vernova, Hitachi Energy, Mitsubishi Electric, and Siemens Energy. The contracts run for five years, with an optional three-year extension.

Carl Trowell, President of Strategic Infrastructure at National Grid, described the initiative as a crucial step in delivering The Great Grid Upgrade. He emphasized the framework’s role in driving efficiencies, fostering innovation, and supporting the UK's economic growth.

The framework will support early projects including Eastern Green Link 4, Sealink, and LionLink, reinforcing energy security and boosting job creation.

Leaders from awarded companies expressed their commitment to supporting the UK's energy transition, highlighting their expertise in HVDC technology and offshore wind infrastructure.

This investment strengthens National Grid’s position as a leader in subsea power transmission, enabling the UK to meet its net-zero goals and advance energy security.
