Data and facts
about the Swiss transmission system

The graphics on the following pages outline key facts and figures concerning the power grid. Swissgrid continuously compiles operating information, analyses it, and leverages it to optimise grid deployment. We use detailed criteria to monitor and assess the status of the transmission system in Switzerland.
