A 405 T transformer rolls through Frankfurt

Germany, Frankfurt: The operator TenneT is modernizing the power supply.

For this purpose, a transformer weighing 405 T was transported through Frankfurt on the night of 13 January.

The colossus was manufactured by General Electric in Mönchengladbach on behalf of the power grid operator TenneT. From there he went by train to the Hanauer Landstrasse marshalling yard in Frankfurt-Fechenheim.

The background to the transport is a comprehensive modernization of the Frankfurt electricity distributor, which has become necessary, among other things, as a result of the switch to renewable energies and green electricity. The infrastructure continues to gain in importance. TenneT announced that the increasing demand for electricity in households, industry and data centres must be met. And future-proof systems are required to transport the “green electricity” from northern Hesse and the coastal areas in northern Germany to the Rhine-Main region.

The transformer stations in and around large cities represent a particular challenge in the nationwide renovation and expansion of the high-voltage networks and distributors. In order to ensure the power supply of hundreds of thousands of households even during the work, the process can only be carried out in stages.

TenneT is investing a total of around $51 M (€45 M) in the site.

The conversion of the 220/110 kV system, which was built in the sixties and seventies, should be completed by 2025.
