The basic service provided by the Transmission System Operator (TSO) consists in transportation of gas fuel from an entry point selected by the Transmission Service User (TSU) to the designated exit point, based on a contract between TSO and TSU. The entry into such a contract is conditional on the acceptance of an application for provision of the transmission service.
In case when no connection line is available or the capacity at the exit point is insufficient, the Applicant requests TSO to issue the terms of connection in accordance with the regulations of the Energy Law. Connection of a new point is established pursuant to a separate connection agreement between TSO and the connected entity for whom the terms of connection have been defined.
Within the transmission service TSO also provides the 5% balancing service, consisting in compensating for balance difference at the input points and output points.
