The commissioning of the Chamoson – Chippis line in the Valais is a milestone in the longest-running EHV line project in Swissgrid’s history. The project started 36 years ago.

Although the situation for the coming winter is tense, and it is not clear whether the usual imports from neighbouring countries will be possible, the importance of an electricity agreement with the EU remains undisputed. There are several reasons for this.

A certain number of safety regulations must be observed at events near extra-high-voltage lines.

The Swiss transmission grid cannot be viewed in isolation; it is firmly integrated into the European interconnected grid. But the established cooperation is at risk. An interview with Andrea Mäder, Head of Public Affairs, about the challenges facing Swissgrid at the heart of Europe.

Drones are used for many things nowadays, and they also have great potential at Swissgrid. Their use in line inspections was tested in a pilot project.

Power shortage and power system failure are two terms that are often confused. But they do not mean the same thing. In the event of a power system failure, there is enough energy in the system in principle. However, a chain of unfortunate circumstances leads to a power failure. In a power shortage, on the other hand, production capacity is insufficient to meet demand.

In Switzerland, a heat wave has no significant impact on the management of the extra-high-voltage grid.

Cows now graze on lush, green grass in meadows where pylons once stood. Before the areas in the Uri valley floor were approved for normal use, Swissgrid carried out extensive soil remediation at the former pylon sites.

In this interview, Asja Derviškadić, Grid Studies Engineer at Swissgrid, tells us how she contributes to Switzerland's security of supply in her role and how she experiences working at Swissgrid as an engineer.

Electricity generation is undergoing fundamental change. Switzerland is in a good position with regard to renewable energies. However, faster expansion of production and storage capacities is needed. An interview with Michael Frank, Director of the Swiss Electricity Industry Association (VSE), about electricity generation now and in the future.

At the «Gäbihübel» it is easy to see the effects of the underground laying of a section of a 380 kV extra-high-voltage line on the landscape and environment as well as the challenges presented with regard to construction, operation and maintenance
