ENTSOG Second Report on Implementation Monitoring 2017 - Interoperability and Data Exchange Rules Network Code

RULES FOR THE MATCHING PROCESS (ARTICLE 8)

The majority of TSOs have confirmed that matching rules, rules for communication and processing of data are established in the IAs.

Article 8(5) a) of the INT NC sets out the application of the lesser rule as matching rule by default. 68 IPs are being operated under this principle.

In 2 cases TSOs agreed to use the processed quantities determined by one of them as confirmed quantities. In case of an exceptional event, at one of these IPs, the affected TSO’s processed quanti- ties can be used as confirmed quantities; at the other one, the “Lesser rule” is applied. In 1 IP, although the lesser rule is used in normal conditions, adjacent TSOs agreed that during exceptional events the affected TSO’s processed quantity prevails and in emergencies, the processed quantities from one side of the IP prevail.

At those IPs where another rule is used as matching rule, TSOs confirmed that users have been invited to comment the procedure.

At 41 IPs, the TSOs which have been declared as flow control equipment operators are also responsible for the matching process.

Regarding the time schedule for the matching process, for 69 IPs TSOs confirmed that it does not take longer than 2 hours, timing corresponds exactly to the time schedule described in Article 8(5) c) of the INT NC, and for 2 IPs within the 69, involved TSOs commented that the time schedule, within the renomination cycles, is less than 1 hour. For one IP, TSOs replied that other schedule is used.

In all IAs, the information and the data exchange mechanism has been defined.
