II.2.4) Description of the procurement:

Energinet and 50 Hertz intends to establish a Supplier Qualification System (“SQS”) for the procurement of HVDC converters, HVDC- and HVAC-substations in connection to the converters. The SQS is mainly intended for interconnector and offshore wind energy related projects such as the Bornholm Energy Island project.

In the following, the requirements for a typical project are outlined. Deviations may, however, occur during the lifespan of the SQS.

The scope of works of the supplier may cover development, design, engineering, relevant studies and reports, procurement, manufacturing, packaging, transportation, delivery, construction, installation, testing, commissioning, maintenance and documentation of HVDC and HVAC installations.

HVDC installations may include:

1. The offshore and/or onshore converters (together ‘the Converters’) for the HVDC Substations and in particular:

a. the primary systems

b. the secondary systems including black start diesel generators

The HVDC substations should

1. be based on VSC-MMC technology, using MMC Building Blocks in a half-bridge arrangement.

2. be arranged as a bipolar system with Dedicated Metallic Return (DMR)

3. have a transmission capacity range from approximately 1,2 to 2 GW

4. have the capability to absorb or generate reactive power independently from the active power (as further specified in each tender)

5. be rated for a DC voltage level of ±525 kV

The HVDC offshore converter stations may, amongst other things, include a DC switchyard (the offshore DC switchyard) that:

In the following, the requirements for a typical project are outlined. Deviations may, however, occur during the lifespan of the SQS.

The scope of works of the supplier may cover development, design, engineering, relevant studies and reports, procurement, manufacturing, packaging, transportation, delivery, construction, installation, testing, commissioning, maintenance and documentation of HVDC and HVAC installations.

HVDC station installations may include:

1. The offshore and/or onshore converters (together ‘the Converters’) for the HVDC Substations and in particular:

a. the primary systems (AC and DC)

b. the secondary systems including but not limited to control and protection systems, black start diesel generators, auxiliary and ancillary systems

The HVDC substations should

1. be Voltage Source Converter (VSC), which must be realised as a multi-level converter half-bridge arrangement.

2. be arranged as a bipolar system with Dedicated Metallic Return (DMR)

3. have a transmission capacity range from approximately 1,2 to 2 GW

4. have the capability to absorb or generate reactive power independently from the active power (as further specified in each tender)

5. be rated for a DC voltage level of ±525 kV

The HVDC converter stations may, amongst other things, include a DC switchyard (the DC switchyard) that:

1. Should have the necessary components to connect and disconnect any combination of the HVDC converter stations of the respective tender under load.

2. Should be prepared so that future expansions can be carried out concurrently with the existing HVDC links being in normal operation. Brief reduction of current in a single pole at a time is allowed.

The offshore AC substations will accommodate connection of offshore wind park connection and supply the local grid.

The deliverables may include onshore HVAC substations.

Further, the deliverables may include a coordinated control system for the overall project’s system.

Finally, the deliverables may include installation, test and subsequent maintenance in connection with the above.
