SMM News: German power grid companies Tent (TenneT Holding BV) and TransnetBW GmbH have awarded underground cable supply contracts for Germany's SuedLink wind power project, with a total value of 2 billion euros ($2.26 billion).

(TSO), two transmission system operators, said they had decided to use plastic insulated underground DC cables with a voltage of 525 kV in the project. Ankat Cable and Prysman subsidiaries, Europe's leading cable manufacturers, have received the above cable orders.

Under the contract, NKT GmbH&Co KG, owned by the Ankat Group, will deliver and install the XLPE high voltage DC (HVDC) onshore cable system at a total contract price of more than 1 billion euros and a line length of about 750km. Production is expected to begin in early 2022 at its plants in Cologne, Germany, and Karlskrona, Sweden.

Prysmian PowerLink Srl will also design, manufacture, supply, lay, combine, test and debug 2 GW underground cable systems from northern Germany to southern Germany as part of an order worth more than 800 million euros. The 700km transmission line will connect Wilster (Wilster), Schleswig-Holstein, to the northwest of Hamburg.

The entire 10 billion euro SuedLink will transport wind from northern Germany to southern Bavaria and Baden-W ü rttemberg. The two grid operators operate separately, with TenneT in charge of the north and TransnetBW in the south of the cable connection.

According to the plan, the whole project should be completed by 2026.
