The Electricity Supply Act (StromVG) and Electricity Supply Ordinance (StromVV) define Swissgrid’s mission and the general conditions for its business activities. Every year Swissgrid calculates the grid usage and system service tariffs for its services – the operation, maintenance and expansion of the transmission grid.
The distribution of costs by Swissgrid takes place according to usage. Where this is not possible, the costs are passed on to the distribution system operators and the end consumers at the respective grid level on the basis of meter data for services and energy and corresponding tariffs and billing rates.
Swissgrid operates in a regulated market under the supervision of the regulatory authority Swiss Federal Electricity Commission (ElCom). The ElCom serves as «price monitor» in the electricity sector and checks the tariffs billed by Swissgrid.
