Whenever we talk about extra-high-voltage lines, their impact on the landscape and nature soon becomes part of the discussion. Is the environment really forgotten about in grid projects? First of all, it is important to stress that Swissgrid is aware of its role as the national grid company and assumes its responsibility towards people and the environment.

In the future, the grid will also be a data highway – and our home will be an energy-optimised, networked work of art. There are a number of challenges to overcome along the way. The electricity grid operators are working closely together to meet these challenges. After all, there is only one grid in Switzerland, and millions of people rely on it every day.

The weather has an influence on the noise under extra-high-voltage lines. But why do you only hear these noises at certain times, and why are they not always equally loud?

The European Network of Transmission System Operators has published its Winter Outlook. In it, it assesses the electricity supply situation. This winter will be more critical than other winters before.

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.
