Network Code on Interoperability

and Data Exchange Rules

Following AWP 2015 and to fulfil the monitoring obligations envisaged in Article 25 of the INT NC, ENTSOG members

provided their responses to an implementation questionnaire agreed by ACER and ENTSOG, including both general and

interconnection-point specific issues.

Based on the replies from participating TSOs, the

report

shows that the majority of interconnection points (IPs) are

operated according to interconnection agreements (IAs)

concluded between adjacent TSOs according to the rules

foreseen in the INT NC.

In the vast majority of agreements, the lesser rule is imple-

mented as the matching rule and the operational balancing

account (OBA) is widely used as the allocation rule. Regard-

ing measurement principles in the IAs, the majority of them

take already into consideration the provisions of the INT NC

and a number of them have been concluded on the basis of

the ENTSOG template.

According to the report, no cross-border trade restrictions

due to differences in gas quality or odourisation practices

that cannot be avoided by mutual cooperation between

TSOs have been detected. Regarding short-term monitoring

requirements, more than 83% of the TSOs are publishing

on their websites Wobbe Index (WI) and Gross Calorific Val-

ue (GCV) for each Entry IP once per hour.

As for data exchange, the majority of TSOs have implement-

ed or are in the progress of implementing one or more of the

common solutions for Nominations & Matching and CAM/

CMP processes. In addition to the common solutions, 82%

of TSOs have advised that existing solutions are staying in

place.

Support the TSOs of Member States, Energy Community

and third countries in the implementation of the NC

The Interoperability team and WG keep building a close co-

operation with the Energy Community through the ReCo

teams and joint workshop on Interoperability and Transpar-

ency (Vienna, 19 October) and advise on the roadmap for

implementation of the NC within the Contracting Parties and

adjacent Member States (1st meeting on implementation of

Gas Network Codes in the Energy Community, Budapest,

7 July).

More information regarding cooperation with Energy Com-

munity and third countries could be found in paragraph 6.1.
