Question 4.1.10
Does the Agency need to be aware about the point direction for which the affected capacity is announced? If yes, how this information shall be provided through XML based on UMM Schema No 2 “Unavailabilities for gas facilities”?
The format for the XMLs for “Unavailabilities for gas facilities” (Schema No2) does not contain attribute for the point direction.
In the context of publication of unavailabilities for gas facilities, an “Affected asset or units” could be the connection point (cross-border, interconnection point, delivery point, measurement point etc.). In case that the affected point is bidirectional, the point capacity is direction dependent, respectively the values of the UMM Schema No2 attributes: Technical capacity, Available capacity and Unavailable capacity depend on the point direction.
In summary, the technical, available and booked capacities in normal circumstances are different for the different point direction. This means that during an event of unavailability both sites of a point could be affected and respectively - the affected capacities are different per point direction.
Answer: As per the format for the reporting of UMMs related to unavailability gas facilities defined in Annex VII of the Manual of Procedures on Data Reporting, Data Field No (15/b) Direction should be used to indicate if the outage is at the entry or exit direction in relation to the specified Balancing Zone.
