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.

Net tariffs, excl. VAT
The tariffs and rates are given in Swiss francs, unless another currency has been given.
Swissgrid sets the tariffs for grid usage in accordance with the legal and regulatory requirements. Swissgrid is entitled to adjust the tariffs within the framework of the legal and regulatory requirements. Swissgrid generally notifies grid users about tariffs in writing three months at the latest prior to the legally prescribed date of publication for grid operators.

Industry document Grid Usage Model for the Swiss Transmission System
The «Grid Usage Model for the Swiss Transmission System» (NNMÜ – CH) is a central electrical industry document for which Swissgrid is responsible. It governs the commercial aspects relating to the usage of the transmission grid and forms the basis for calculating grid usage tariffs.
