Capacity trading platforms - absence of harmonisation across Europe
The absence of harmonisation among TSO regarding capacity trading is in contradiction with the NC on interoperability. Capacity trading affects gas availability and gas prices that is why we strongly believe that it should be harmonised via a document based solution using Edig@s format.
An automatization of capacity trading process (Follow-up on overall available capacity at a connection point, Capacity booking and surrender, Follow-up on portfolio capacity availably) currently requires :
- Development of a specific interface for Prisma booking as well as evolving it to follow changes
- Development of a specific interface with GazSystem as well as evolving it to follow changes
- Development of a specific interface with Gassco as well as evolving it to follow changes
- Development of a specific interface with FGSz as well as evolving it to follow changes
- Development of a specific interface with National Grid as well as evolving it to follow changes
- Taking into account of a TSO management for over-nomination or curtailments
Entsog's common exchange solution table defines interactive date exchange for capacity trading. That'll very likely mean that in addition to the listed above a network user will have to implement more specific interfaces with the market developing further (Greece, Ukraine, Baltic countries ...)

Public consultation to understand network users’ preferences in having a common format and protocol for communication to Capacity Booking Platforms
To achieve harmonisation ACER and ENTSOG propose the following steps to
be undertaken in order to provide a solution for the reported issue:
• ENTSOG will propose to change the Common data exchange solutions table (CNOT)
and propose document-based exchange solution for capacity (interactions between
Network Users and Capacity Booking Platforms) and leave the interactive data
exchange as a voluntary option.
• An amendment of the INT&DE NC as detailed in Annex I. It is proposed to amend the
following Articles: 1(2), 20 (1) & (2) and 23(1) & (2). The amendment reflects the
proposals provided for the previous FUNC case on data exchange at VTP and storage.
• In the future further studies can be developed to assess the impact of higher-level
harmonisation of this issue.
• The proposed amendments for the specific processes are described in the Common
Data Exchange Solution Table as detailed in Annex II.
• Please note that ultimate outcome of the proposals may deviate from the proposed
solutions described in Annex I & II because additional process steps outside the FUNC
process are required. Annex I has to go through a comitology process lead by the
European Commission. Annex II has to be publicly consulted as this is the part of the
amendment process of the Common Network Operation tools as stated in INT & DE
NC Art. 24 (2). The results of the consultation on the Common Data Exchange Solution
Table may trigger further amendments of the INT & DE NC next to those proposed in
For further details, reference is made to the Solution note and Annexes below.
