ENTSOG TYNDP 2017 - Main Report

FURTHER IMPROVEMENTS AND ADDITIONS TO THE TYNDP

The modelling has been improved along the following lines: \\ A separate assessment of the whole year situation and the high demand situa- tions: national design case peak day (DC) and 1-in-20-year 2-week high demand case (2W). Separating the assessment is more realistic as it avoids the simulation anticipating the high demand situation. This allows use of the storage level calculated from the whole year simulation as starting point for the high demand situations. Additionally, it allows the impact of the different situations to be computed independently. \\ An improved modelling of the LNG terminals, developed in cooperation with GLE, to better reflect the annual and peak capacities. \\ A refined modelling of storages has been introduced by matching the summer and winter period for the whole year simulation with the injection (April to Octo- ber) and withdrawal (November to March) periods. Additionally, the modelling uses withdrawal capacity curves (function of the storage level) recently updat- ed in cooperation with GSE. The following elements have also been added to the TYNDP: \\ A section on the achievement of the EU 2030 energy and climate targets for the different scenarios, in the Demand chapter. \\ A qualitative analysis of the embedded diversification of the LNG supply source, developed by GLE, in the Supply chapter. \\ An Energy Transition sub-chapter providing an insight into how gas infrastruc- ture can be an essential part of the future integrated energy system based on sector coupling, in the Infrastructure chapter. \\ As required by Regulation (EU) 2015/703, a regional-level Long-term Gas Quality Monitoring Outlook, based on TYNDP results, in a dedicated chapter and respective annex. \\ A TYNDP project Map displaying the projects submitted to the TYNDP togeth- er with their advancement status and labelling the projects part of the 2 nd PCI list, available as an electronic Annex to the TYNDP, and for which a paper version will be provided together with the TYNDP printed version.
