Transmission

Import, export and transit

Import refers to the energy volume that flows into Switzerland from abroad, while export indicates the energy volume that leaves Switzerland in the other direction. Transit refers to the energy fed in from abroad every 15 minutes that is not consumed in Switzerland during the same 15 minutes.

Transmission grid losses

The electrical transmission grid always incurs losses due to the physics involved. These losses are caused by resistances such as lines or transformers, and they are emitted into the surroundings as heat. Factors such as the grid load, the outside temperature and the switching states in the grid have an impact on the volumes lost. As a transmission system operator, Swissgrid covers these losses by procuring the corresponding electricity volumes on the energy market. Ultimately, the volume lost also depends on the electricity volume transported.
