The "Terms of Grid Connection and Grid Access" are based on the "TransmissionCode 2007 - Grid and System Regulations of German Transmission System Operators”. The "Terms of Grid Connection and Grid Access" define the minimum technical requirements for connection to the 50Hertz transmission system and the criteria governing feed-in from production units (PUs), including those using renewable energy sources, in the 50Hertz control area. They are subject to amendment, in particular if and when changes to the business or legal environment of the transmission system operator (TSO) occur.
Furthermore, the tasks of system management and the assumption of system responsibility of the TSO vis-à-vis the system connection customers are described in clear terms, and the latter’s participation in system support services is set out.
The Terms form an integral part of the grid connection and grid use contracts to be concluded with the market parties.
Grid connection customers are obliged to comply with the given minimum requirements. 50Hertz reserves the right to verify compliance with the “Terms of Grid Connection and Grid Access”. Grid connection customers are expected to provide all assistance required.
