ENTSOG TYNDP 2015

7.7 Way forward

Since the first edition of the Union-Wide Ten Year Network Development Plan, ENTSOG is pursuing the same objective of assessing the long term adequacy of gas supply and demand and the consistent develop- ment of gas infrastructures. The TYNDP is a living organism and each edition differs from the previous one. The same will happen with the next edition as it will look two further years ahead and will have to meet new expectations coming from an evolving market. Further influences are expected from the full implementation of the new network codes and new regulatory requirements. From a regulatory perspective next TYNDP edition will have to cover the long term monitoring of gas quality as defined under the Network Code on Interoperability and Data Exchange. The feedback of the second selection of PCI, based on TYNDP, will certainly also provide ground for improvement of the methodology. Finally the ongo- ing discussion on the review of the Regulation on Security of Supply could impact the role of ENTSOG in the assessment of the European gas system. The TEN-E Regulation has also set to ENTSOs the objective of defining a joint gas and electricity network and market model. Both associations have already accom- plished a big step in that direction with the modelling in this TYNDP of the gas demand for power generation based on ENTSO-E and market data. ENTSOG hopes that the public consultation on this Report will confirm it meets stakeholders and institutions key expectations. At the same time, it will give a view on the future challenges to be taken up by ENTSOG. The same will go with the ACER opinion on the report. This constant evolution gives a predominant role to the consultation process which has multiple purposes, all of the same importance. First it ensures the adequacy of the TYNDP concept with stakeholder expectations and regulatory requirements which often requires the definition of a consensus among diverging views. Then it is supporting the elaboration of the methodology where the right balance should be defined between complexity and comprehensibility. Finally it should enable the sharing of information between market players and institutions in order to define the necessary data set which has a strong influence on the quality of the assessment. Experience has proven that the last two objectives are difficult to achieve. Every stakeholder has his own expectations regarding the TYNDP, therefore compromise has to be reached on the scope of the report. Then the improvement of the method- ology has required the use of data beyond TSO remit such as commodity prices or supply availability. On this point little feedback has been received from stakeholders on the ENTSOG default proposal even if the selection of scenarios has as much im- portance as the methodology itself. Therefore every reader is invited to engage in discussions with ENTSOG on the way to improve the report and to prepare challenges ahead. ENTSOG will provide many opportunities to do so through public consultation, workshops and Stakehold- er Joint Working Sessions. Specific proposals to improve the methodology and the dataset will be particularly appreciated.
