Energinet and 50Hertz plan to establish a Supplier Qualification System (SQS) for the procurement of high-voltage direct current (HVDC) converter substations with the SQS mainly intended for interconnector and offshore wind-related projects such as the Bornholm Energy Island project.

The scope of work of the supplier may cover development, design, engineering, relevant studies and reports, procurement, manufacturing, packaging, transportation, delivery, construction, installation, commissioning, maintenance and documentation of HVDC and high-voltage alternate current (HVAC) installations.
