Published requirement description

National Grid is an international Electricity and Gas Network Company and one of the largest investor-owned energy companies in the world, based in the United Kingdom with operations in the north-east of the United States of America.

National Grid is looking to establish a multi-year High Voltage Direct Current (HVDC) Major Works & Civils Framework, primarily to service its growing HVDC requirements. The scope of this Procurement includes c.15 HVDC projects; certain projects, and other identified projects that it is currently anticipated will be of similar size and value and will be identified as infrastructure to enable the connection of 50GW of Offshore Wind by 2030 and Net Zero by 2050. The scope also comprises other as-yet unidentified additional major HVDC projects, the precise location and nature of which is not yet known but which will share the same key features as the other projects.

National Grid's HVDC Major Works & Civils Framework includes but is not limited to civil engineering & construction works for National Grid's High Voltage Direct Current project portfolio, including construction of converter stations and installation of UHV cable.

National Grid reserves its rights to utilise different procurement routes for converter civil works (i.e., turnkey delivery through the HVDC Converter Systems Framework) and cable civil works (i.e., turnkey delivery through the HVDC Cable Framework) on a project-by-project basis.
