Incremental capacity procedure


This market demand assessment is carried out in the framework of the Regulation (EU) 2017/459 of 16 March 2017 establishing a network code on capacity allocation mechanisms in gas transmission systems and repealing Regulation (EU) No 984/2013 (CAM NC).

For harmonizing the process for the development of incremental capacity in the European Union, provisions on the incremental capacity process have been introduced by the 2017 CAM NC amendment which is a standardised procedure for market participants to indicate in a non-binding way their demand for incremental capacity.

The first market demand assessment for incremental capacity was conducted in 2017. This year, GAZ-SYSTEM S.A. will conduct a second non-binding market demand assessment for incremental capacity between Polish and neighbouring transmission systems. The non-binding market demand assessment for incremental capacity will start on 1 July 2019 and will last for 8 weeks, i.e. until 26 August 2019. For the first time, the procedure will be carried out through the new functionality of the GSA Platform. In accordance with the applicable GSA Platform Rules GAZ-SYSTEM S.A. charges no fees for submitting non-binding requirements.

Based on the non-binding demand indications received under this year’s procedure for assessing market demand for incremental capacity, GAZ-SYSTEM S.A. and adjacent transmission system operators will produce common market demand assessment reports, each covering all interconnection points connecting given entry-exit system. The reports will estimate the potential demand for incremental capacity on each entry-exit system and state whether it is necessary to initiate an incremental capacity project.

The market demand assessment reports will be published no later than 16 weeks after the start of the procedure, by 21 October 2019 at the latest, at the websites of transmission system operators.

Interested network users are asked to indicate their non-binding demand indications for incremental capacity through the GSA Platform until 26 August 2019 16.00 (CEST).

All questions about the market demand assessment for incremental capacity shall be sent to the e-mail address:
