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!
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.
Stable grid operation with high solar power production
The proportion of renewable energies in Switzerland is increasing every year, with the largest growth coming from photovoltaic plants. However, solar power production depends on the weather and is very volatile. That is why data and forecasts need to be as accurate and up to date as possible to ensure the secure and stable operation of the transmission grid. Yet the quality of data and forecasts has been lagging behind the expansion of photovoltaic plants for some years now, leading to an urgent need for innovation.
Andreas Schreiber and Zuzana Filková explain why a stable grid shouldn’t be taken for granted in the future, the challenges Swissgrid is facing, and what the tariffs comprise.
The Lachmatt substation in Pratteln is being modernised to meet the increasing electricity requirements in the Basel region. A new 380-kV switchgear and a coupling transformer will increase security of supply in the Basel region in the future and facilitate international electricity exchange with Germany and France. Protecting the environment is a high priority during the construction work.
