Until now, we have been operating our EHV grid using overhead power lines and alternating current at two different voltage levels: 220 and 380 kilovolts. In addition to the power lines, other important elements of the transmission grid include substations , transformers and converters .
The main demand made of our network is that it should transport electricity safely, reliably and efficiently from the producer to the consumer. But Germany’s and Europe’s energy landscape is in a state of transition. We are adapting our transmission grid to this transition and making it even more capable and flexible than it already is. New technologies such as DC transmission and underground cabling for EHV routes offer us additional options for shaping grid expansion in line with the legal parameters.
