NETWORK CODE INTEROPERABILITY & DATA EXCHANGE

Final Comitology

The Gas Committee approved the INT Network Code

(INT NC) at the second comitology meeting, held 3–4 No-

vember 2014. For several months, INT NC was subjected to

scrutiny and then published in the Official Journal of the

European Union on 30 April 2015. It subsequently came

into force on 20 May 2015. It shall apply from 1 May 2016

onwards without prejudice to Article 5 (see next section on

IA Template).

IA template

ENTSOG developed a draft interconnection agreement

template (as required by Article 5 of INT NC) that was

published in June 2015. It covers the default terms and

conditions set out in Articles 6 to 10 of the network code

which define key technical and operational areas of inter-

connection points.

In October, ACER provided its opinion welcoming the publi-

cation of the draft and made two recommendations. Firstly,

the Agency suggested presenting the default rules (i. e., the

minimum mandatory content of an agreement) separately

from the guidance on their application. This should bring

the template closer to the format of an agreement or an ad-

dition to one. Secondly, ACER recommended complement-

ing the separated guidance document on default rules with

samples from existing interconnection agreements.

In December 2015, ENTSOG published the final version

of the template addressing the document structure

recommendations from ACER and proposing to publish the

samples by 1 May 2016. This would allow the existing

agreements to be duly revised and ready for the applicabil-

ity of INT NC.

Long-Term Gas Quality Outlook

Article 18 of INT NC assigns ENTSOG the task of publishing

the long-term gas quality monitoring outlook for transmis-

sion systems. The forecast will identify the potential trends

of gas quality parameters and respective potential variabili-

ty within the next ten years and will be published along with

TYNDP 2017.

In the second half of 2015, System Operation and System

Development teams began an intense cooperation to fulfil

this new requirement by developing a robust methodology

that yields a meaningful outcome.

The first version of the Long-Term Gas Quality Outlook mod-

el gives a range of the gas quality forecasts per region, only

the Gross Calorific Value and Wobbe Index parameters are

taken into consideration.
