It is hard to imagine our daily life without the numerous electronic gadgets and tools. However, we are much less aware that electric and magnetic fields are formed everywhere electricity is present: including in the generation, transmission and distribution of electric energy.

Swissgrid cooperates with universities to develop the new technologies and methods required to enable the efficient and secure transmission of energy.

The decision on whether to install a high-voltage line as an overhead line or as an underground cable is based on objective criteria. That's why Swissgrid checks the cable and overhead line options for every grid project.
