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!
Switzerland is dependent on electricity exchange with Europe
Switzerland has been a hub in the European electricity system for decades. The star of Laufenburg interconnected the grids in Germany, France and Switzerland for the first time, and the Swiss grid has been closely integrated into the European interconnected grid ever since.
The human circulatory system and the electricity grid both have an indicator that shows how well they are working. In the human body, it is blood pressure, while in the grid, it is voltage.
Work is carried out during the day, electricity flows at night. This is the daily routine on the extra-high-voltage power line that crosses the Sanetsch Pass between the canton of Valais and the canton of Bern.
Electricity never stops flowing – a night in the grid control room
I usually go to the office for the standard nine-to-five workday. But today I’m not setting off for work until the evening. I’ll be in the Swissgrid building at 9 p.m., but not at my usual workplace: today I’ll be in the grid control room.
The power failure in Spain and Portugal has raised many questions – including the supply of electricity in Switzerland. What impact did the power failure have on Switzerland? And how does the grid work?
Laying new underground cables in the Swiss transmission grid only remains possible to a very limited extent. This is the result of the Swissgrid cable study, which shows that the physical properties of underground cables make stable grid operation and the rectification of disturbances much more difficult.
Regional grid coordination: when 1 plus 1 is more than 2
When it comes to regional grid coordination for the grid of the future, 1 plus 1 is more than 2: thanks to synergies, a better grid with fewer line routes is being created.
The sun as a resource for ensuring the stable operation of the grid
Operating the grid is a balancing act to keep the consumption and generation of electricity constantly in equilibrium. Swissgrid uses control energy to maintain the necessary balance. Photovoltaic plants will also help to stabilise the grid in the future.
Bastian Schwark, Head of Market Operations at Swissgrid, explains why the demand for control energy has increased, what role solar expansion plays in this growth, and how precise forecasts and innovative market designs can help to reduce costs.
