Grid operations

Here you can find information on Grid Operations, whose role is to ensure the secure, reliable and cost-effective operation of the Swiss transmission system and the Swiss electricity market.

Electricity or electrical energy cannot be stored in large quantities by conventional means, so at any given point in time, the amount of electricity produced must correspond exactly to the amount being used. This balance guarantees the secure supply of electricity at a constant frequency of 50 Hertz (Hz). Unforeseen fluctuations between the feeding-in and withdrawal of electrical energy in the grid must be balanced out at short notice.  This is achieved by the suppliers of electricity increasing or reducing the volume of energy being fed in or withdrawn. This is one of a range of ancillary services (AS) provided mainly by power plants.
