Swissgrid invests in the grid of the future
With the Strategic Grid 2040, Swissgrid is setting the course for a secure, efficient and climate-friendly electricity supply in Switzerland. Central projects are intended to make the transmission grid fit for the energy future.
The transmission grid is the basis for a secure electricity supply in Switzerland and its importance is growing. Decarbonization, decentralization and digitalization are fundamentally changing the energy system. Swissgrid is responding to these developments with the “Strategic Grid 2040” project and has identified 31 key projects that need to be implemented by 2040. Around CHF 5.5 billion is to be invested in the expansion, modernization and controllability of the grid.
Growing demands on the grid
The transformation of the energy supply is leading to new burdens. Electricity consumption is rising sharply due to heat pumps, electromobility and data centers. At the same time, feed-in from volatile, decentralized sources is increasing. International electricity flows are increasing due to wind farms and solar farms in Europe. To meet these challenges, Swissgrid is focusing on targeted grid reinforcements, new phase-shifting transformers to control electricity flows and the comprehensive renovation of existing infrastructure.
Planning with foresight and consideration
The NOVA principle (grid optimization before grid reinforcement before grid expansion) is at the heart of the strategy. The grid is only expanded when all other options have been exhausted. This minimizes costs and environmental impact. At the same time, coordinated planning with cantons and partners and early involvement of the public will increase acceptance and speed up the planning process.
Networking beyond national borders
Swissgrid is not only planning for Switzerland, but also for the European energy future. A closer connection to the European grid and integration into a future supergrid should help to transport electricity more efficiently across continents. A regulated electricity agreement with the EU remains crucial for this integration.
