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!
Everyone benefits from a harmonious relationship with the EU
The relationship between Switzerland and the EU poses challenges for all Swiss electricity market players. In the summer of 2023, the Federal Council adopted benchmarks for a negotiating mandate with the EU, thereby driving forward the relationship. The decision on the negotiating mandate is now imminent. In an interview, Marc Ritter, CEO of AEW Energie AG, explains the significance of this development and of a potential electricity agreement with the EU for a Swiss power supply company.
Possible power shortages, power system failures, blackouts – these were topics of much discussion last year. Why is the electricity grid reaching its limits and what is Swissgrid doing to counteract this?
How a unified Swiss electricity grid came into being
Electricity was never invented – it has always existed. It is a natural phenomenon. But everything relating to electricity was invented: how we produce it, how we transport it to businesses and households, and how we use it in everyday life.
«As far as possible, energy should be produced where it is consumed.»
If the switch to renewable energies is to succeed, there needs to be more electrification and networking of buildings and mobility both regionally and locally. A conversation with Dr Kristina Orehounig, Head of the Urban Energy Systems department at the Swiss Federal Laboratories for Materials Testing and Research (Empa).
Unplanned flows in the grid – a risk for Switzerland
The grid capacity of the Swiss transmission grid is precisely calculated to the nearest quarter of an hour. If unplanned electricity suddenly flows through our grid, i.e. electricity that was not foreseen in the calculations, this can cause overloads of grid elements.
The Swissgrid substation at Fionnay GD in the Valais, which is located in a mountain cave, has been renovated. This is where the energy generated by the Fionnay / Grande Dixence power plant is fed into the electricity transmission system.
In the first post in the blog series, we looked at the home of the future and saw an energy-optimised, networked work of art. For this vision to become reality, the infrastructure – i.e. the grid – must keep pace with digitalisation and the transformation of the energy system.
