Construction of the first UK-Denmark submarine high-voltage DC cable officially started

Recently, Danish grid operator Energinet and National Grid officially awarded a 1.
1 billion euro project contract, marking the official start of construction
of Viking Link, the first submarine high-voltage DC system connecting the UK and Denmark.

According to reports, this submarine high-voltage DC cable is the first interconnection system connecting the power grids of the United Kingdom and Denmark, with a transmission capacity of up to 1400 megawatts
.

German industrial giant Siemens has been awarded a contract of about 300 million euros to build converter stations in two countries, and work will start
next year.

Pryssmann, the world's largest cable manufacturer, has been awarded a contract worth nearly €700 million to design, manufacture and install HVDC cables for the grid interconnection system, including the entire 1,250 km submarine cable for the subsea section and 135 km of land cable
in the UK.

At the same time, Danish cable company NKT has also been awarded a contract worth 90 million euros to supply about 150 km of 525 kV MI HVDC land cables for the project to connect the Danish coast to the Revsing grid substation in the south of Geneva, which is expected to start
next year.

Danish transmission system operator (TSO) Energinet and National Grid said all of the above contracts are expected to be signed
by the end of August.

The 760-kilometre undersea interconnection system, which represents the first submarine cable connection between the UK and Denmark, will provide clean electricity
to more than 1.
4 million homes, representing the first submarine cable connection between the UK and Denmark.

According to the plan, by the end of 2023, the Viking subsea HVDC system will be put into operation
.
