TenneT, a leading European transmission system operator, has deployed a large power transformer weighing 395 tonnes with an exceptional output of 650 megavolt amperes (MVA). This massive unit can theoretically supply electricity to around one million households. As part of the Ostbayernring project, the transformer will function as a compound dome transformer, playing a key role in modernizing Germany‘s high‑voltage grid.
The Ostbayernring project involves converting TenneT’s network to 380,000 volts between the Redwitz substation (Lichtenfels district) and Schwandorf. Additionally, 220,000‑volt connections from Schwandorf will supply the Regensburg and Nuremberg regions in the future.
Therefore, this large power transformer is not only notable for its size and capacity but also critical for ensuring reliable power transmission to hundreds of thousands of households and industrial customers.
Moving a 395‑tonne transformer requires meticulous planning. The heavy‑duty transporter carried the unit from a logistics point to the waste‑to‑energy plant in Schwandorf. The journey covered only five kilometers, but it took approximately two hours due to the size and weight of the load.
Such specialized transport demonstrates the engineering challenges behind large power transformer installations – from factory to substation.
| Parameter | Value |
|---|---|
| Weight | 395 tonnes |
| Power rating | 650 MVA |
| Voltage levels | 380 kV (main), 220 kV (connections) |
| Application | Grid conversion, substation upgrade |
| Service area | Redwitz – Schwandorf, plus Regensburg & Nuremberg |
Upgrading transmission infrastructure with large power transformer units like this one is essential for integrating renewable energy, stabilizing grids, and replacing aging equipment. As Europe pushes toward carbon neutrality, projects such as Ostbayernring will become more common.
Consequently, demand for high‑capacity, reliable power transformers will continue to grow.
