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!
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.
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.
Binoculars used to be needed, but today, drones can take over
Swissgrid is opting for drone technology for inspecting overhead lines. This technology will further optimise the maintenance of the transmission grid and drive forward the digitalisation of grid inspections.
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.
«Companies from third countries also have the right to be heard»
The Court of Justice of the European Union (CJEU) has ruled in favour of Swissgrid in the proceedings concerning participation in the TERRE control energy platform.
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.
New power lines in the Maggia Valley to contribute to the energy transition
Swissgrid welcomes the Federal Council’s recent decision to define the planning corridor for the new power lines between All’Acqua (Bedretto Valley) and Magadino.
