Glossary for the Rules of the Swiss Electricity Market

1st Edition 2010, V1.0

The Transmission Code is a regulatory mechanism that defines the technical and organisational principles governing the Swiss transmission system and sets out minimum requirements for its operation and use. The Transmission Code describes the tasks and functions of the involved parties and governs the interfaces between swissgrid and the relevant market players. The provisions of the Transmission Code concern the relationship between swissgrid and distribution system operators, electricity generators, end consumers and other electricity market players.
