TenneT transports Siemens Energy transformers to Würgau substation for Bavarian green electricity hub

GERMANY - The network operator TenneT is transporting four phase-shifting transformers manufactured by Siemens Energy to expand the Würgau system, the future Bavarian hub for green electricity.

With an operating weight of 940 tons each, the four new transversely controllable transformers will enable TenneT to make the best use of two existing north-south circuits between the Redwitz substations in the Lichtenfels and Würgau districts and Raitersaich in the Fürth district of Bavaria, TenneT said in a press release.

Due to its size, each transformer consists of two transformer tanks, each of which has a transport weight of up to 326 tons.

The first four transformer boilers are delivered by the transport specialists from Kahl and Jansen. The units are first transported by train from the manufacturer Siemens Energy and its plant in Weiz, Austria, to the port of Linz. From there, the route continues by barge to the Bavarian port of Bamberg and then by road over the challenging Würgauer Berg to the substation.

The second four transformer boilers will be transported by heavy-duty experts from Kübler in July and August by barge to Nuremberg and from there first by train to Lichtenfels. Here the road transport takes place over the western Upper Main hill country to Würgau. The transport is expected to be fully carried out by late summer 2021.

For two years now, TenneT has been preparing the Würgau substation for what are currently the largest transformers in the German TenneT network. The company has invested $82.7 million in the Upper Franconian plant which is to become the Bavarian hub for green electricity. With these investments, Tennet is laying an additional foundation for the success of the energy transition in Franconia, Bavaria and ultimately also for the safe north-south transport of electricity from renewable sources within Germany, the company said in a press release.
