The Single Sided Nomination (SSN) mechanism is defined in the Business Requirements Specification for the Nomination and Matching Procedures In Gas Transmission Systems (NOM BRS) document developed by ENTSOG on the basis of Commission Regulation (EU) 2015/703 of 30 April 2015 establishing a network code for interoperability and data exchange rules.

List of points and the roles of GAZ-SYSTEM S.A.

Authorization process
Possibility of using “single-sided nomination” (SSN) at entry/exit points where GAZ-SYSTEM S.A. plays the role of a passive operator is conditional on the Shipper's authorisation towards GAZ-SYSTEM, pursuant to which the Shipper informs GAZ-SYSTEM about the authorisation of its counterparty to submit, in its name and on its behalf, a single-sided nomination to the operator of the neighbouring transmission system acting as the active operator at a given point.

In order to carry out the authorisation process, an appropriate declaration, signed in accordance with the principles of Shipper's representation, should be submitted to GAZ-SYSTEM S.A. within 5 working days before the date on which the authorisation is to become effective. The declaration should be accompanied by documents confirming the authority of the person acting on behalf of the Shipper to represent the Shipper with respect to the statement.

In case of withdrawal of the authorisation granted by the Shipper to its contractor, the Shipper is obliged to inform GAZ-SYSTEM about this fact by sending an updated statement of authorisation.

Authorization is not required for point 777001 LNG Terminal.

Suspension of the authorisation process
In case when during the validity period of a ZUP authorization submitted to GAZ-SYSTEM, which entitles the ZUP contractor to submit "single-sided nominations (SSN) to the operator active at a given point, the ZUP submits for a given gas day a nomination to GAZ-SYSTEM as a passive operator (double-sided nomination), for this gas day the authorization is suspended and the nomination submitted by the ZUP to the passive operator is considered by the passive operator. A traditional (double-sided) nomination takes precedence over a “single-sided nomination”.

Format for exchanging information in the SSN process
Submitting a “single-sided nomination” to Gas Transmission Operator GAZ-SYSTEM S.A. playing the role of an active operator at a given point, is only possible with the use of the Edig@s 5.1 information exchange format. (message NOMINT 01G, nomination type A01).
