The substation Heide-West in the most northern German federal state of Schleswig-Holstein is an important node of the “Westküstenleitung” (“West-Coast-Line”), which is planned and currently constructed by TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO). This 380kV power line with a length of about 140km is one of TenneT’s numerous projects to transmit green electricity generated by wind farms in the German north to the main consumption centres in the west and south. The “West-Coast-Line” will also enhance transmission capacities between Denmark and Germany.
In the course of this week, two direct coupling transformers, the core elements of the substation, are to arrive at Heide-West. With a capacity of 300MVA each, they are capable of transforming electricity for around one million households. By connecting TenneT’s extra high-voltage grid to the 110kV grid of the local distributor, the transformers ensure the integration of wind power into the supra-regional transmission system. The transformers reached the port of Büsum by ship earlier this month, and since they both have a transport weight of 260t, they will be delivered individually in the period from 20 to 23 December by means of heavy-duty road transport.
