Tender description

The GridLink Interconnector comprises a nominal 1 400 MW high voltage, direct current (HVDC) electricity link between the UK and France. The overall project comprises 2 subsea HVDC cables and a fibre optic cable connecting to a symmetrical monopole, Voltage Source Converter (VSC) converter station located at Kingsnorth on the Isle of Grain, Kent in the UK and at Dunkerque, Nord Department, Nord-Pas-de-Calais Region in France. The converter stations are subsequently connected by underground High voltage, alternating current (HVAC) electricity cables to the National Grid Kingsnorth 400 kV sub-station in the UK and RTE Warande 400 kV sub-station in France. The scope of the procurement relates to the engineering, procurement and construction of the converter stations in UK and France, and approximately 1,5 km of underground HVAC cable in the UK. The scope of the procurement relates to the engineering, procurement and construction, including related site preparation works and foundations, manufacture, supply and installation of equipment, erection of buildings and installation of site services and ancillary facilities, for: (a) one 1 400 MW, 525 kV symmetrical monopole, Voltage source converter (VSC) converter station at Kingsnorth in the UK; (b) one 1 400 MW, 525 kV symmetrical monopole, Voltage source converter (VSC) converter station at Dunkerque in France; and (c) approximately 1,5 km of underground 400 kV HVAC cable between the converter station and the National Grid's Kingsnorth 400 kV sub-station at Kingsnorth in the UK. The scope of the contract requirements are: — detailed design, — engineering, — procurement, — manufacture, — supply, — transportation, — installation, — construction (including civil works), — testing, — commissioning, — spares storage, — operational spares during warranty period, — interfaces with other suppliers, — such other works, services and goods that may be necessary for the engineering, procurement and construction, and subsequent commissioning, commercial operation and maintenance of, the HVDC converter stations and underground HVAC cable in the UK, — spares supply and replenishment (25 years duration), — maintenance and repair services (10 years duration).
