Electricity is always flowing and the energy sector is always active – 24/7, 365 days a year. New grid projects, exciting facts about electricity, digitalisation, innovations, the environment – we regularly publish informative articles on a wide range of topics. Always up-to-date, always with our finger on the pulse. Welcome to our blog!
The expansion of domestic production capacity is essential in order to ensure a successful energy transition in Switzerland and to strengthen security of supply in the long term. This became even clearer in the light of the supply situation in the winter of 2022/2023.
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.
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.
Soil remediation in the Uri valley floor to benefit agriculture and the environment
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.
Nesting boxes for jackdaw colonies have been installed on pylons of the Swiss extra-high-voltage grid in Weinfelden and in the Saint-Triphon region. In other parts of Switzerland, too, electricity pylons provide a home for endangered bird species.
The assembly of the cable connection gantry for the La Bâtiaz – Le Verney underground link and the replacement of pylon 51 on the Chamoson – Romanel 380 kV overhead line are under way at the Verney construction site in Martigny. These two elements are essential for connecting the underground link to the Swiss extra-high-voltage grid. The underground cable link is scheduled to be commissioned in spring 2022.
EU transmission system operators have had to implement the 70% rule since 1 January 2020, with a transition period until the end of 2025. The impact of this rule on Switzerland is not easy to explain. We’ll try all the same.
