Elia and National Grid Nemo Link Interconnector

Elia and National Grid Nemo Link Interconnector

Teshmont provided Owner's Engineer services for the Nemo Link Interconnector project, a 1000 MW, 400 kV HVDC submarine link between the UK and Belgium, which will utilize Voltage Source Converter (VSC) technology in a symmetrical bipole arrangement.

Teshmont developed two specifications for the Nemo HVDC Project, namely:

  • HVDC converter station specification package, which included a description of functional requirements for design, supply, and installation of two VSC HVDC converter stations including the dc equipment, ac equipment associated with the VSC interface transformers, and buildings associated with the converter stations.
  • HVDC land and submarine cable specification package, which included a description of functional requirements for design, supply, and installation of submarine and underground HVDC cables, terminations, splices and auxiliary equipment.

The specifications were developed to allow Suppliers to optimize the voltage, either 350 kV or 400 kV, and the cable specification allowed the suppliers to propose their optimal cable, namely Mass Impregnated (MI) or Cross Linked Polyethylene (XLPE).

Teshmont’s team also provided technical bid evaluation services for this project which involved reviewing the various bids, asking clarification questions to the bidders, assessing the clarification responses, and providing recommendations.

The project will include the worlds’ first 400 kV XLPE submarine cable.
