Energy transition

The energy system in Switzerland and Europe is undergoing radical change and is fundamentally altering the framework conditions for ensuring a reliable supply of electricity in Switzerland. The transition from large centralised power plants to decentralised, renewable energy sources marks a structural change in the production landscape. Due to the growing proportion of solar and wind energy, electricity generation is becoming increasingly volatile and complex to predict. At the same time, electricity demandcontrol are increasing significantly, driven by decarbonisation, digitalisation and the growth of the economy and society. Storage solutions – ranging from large pumped storage power plants and batteries to decentralised energy storage in buildings and electric vehicles – will play a more and more important role in the energy system of the future.

The grid connects these changing elements of the energy system and forms the backbone of a secure supply of electricity in Switzerland. As the operator of the extra-high-voltage grid in the heart of Europe, Swissgrid is also an important hub in the continental interconnected grid. While the integrated electricity system is vital for efficient, long-term security of supply, the increase in large-scale, volatile international electricity flows is also associated with new challenges for secure grid operation.

The transformation of the energy system across Europe is leading to a rise in complexity and placing greater demands on grid operators for ensuring secure and efficient grid operations. For Swissgrid, this means that the transmission grid, grid operations and the market for grid and ancillary services must be enhanced in order to meet future requirements. The only way to integrate renewable energy sources and storage solutions into the electricity system efficiently and safely is by providing a modern and reliable grid and adopting innovative, flexible and market-based solutions. In addition, close cooperation between all players – grid operators, producers and consumers – both nationally and internationally is crucial for the success of the energy transition.
