ENTSOG TYNDP 2017 - Main Report

The following two chapters covers the projects submitted to TYNDP. The Infrastruc- ture chapter provides a detailed overview of gas infrastructure projects as submit- ted by the promoters. It details the project collection process, informs on the project statuses and infrastructure levels, and provides an in-depth analysis of the projects, including in terms of progress since the previous TYNDP and regarding investment costs. The Barriers to Investment chapter analyses the obstacles to future investment in gas infrastructure, combining the views of all TSOs and other project promoters. These chapters are supported by Annex A which provides all non-confidential information on the projects submitted as well as project fiches, and by the TYNDP project Map . The Assessment chapter represents the TYNDP-Step of the Energy System Wide Cost-Benefit Analysis Methodology. It consists of the Supply Adequacy Outlook , the Assessment of the infrastructure needs under the low infrastructure level and the Energy System Wide assessment of the advanced projects . The analysis covers the three assessed scenarios (Blue Transition, Green Evolution, EU Green Revolution), looking at the sustainability, security of supply, competition and market integration perspectives. A specific section is dedicated to analysing the overall impact of the 2 nd PCI list projects as a feedback loop. This chapter is supported by Annex D which provides detailed information on the topology and capacities, existing and developed by projects for the different infrastructure levels. It is also supported by Annex E, which provides all modelling results, and Annex F, which describes the modelling tool and modelling methodology. Assessment Chapter is also complemented by the Energy Transition chapter providing an insight into how gas infrastructure can be an essential part of the future integrated energy system based on sector coupling. The last chapter covers the Long-term Gas Quality Monitoring Outlook , based on the TYNDP results and developed in accordance with the Regulation (EU) No. 2015/703. It is supported by Annex G which provides additional quantitative results. In addition, the required L to H conversion of areas currently supplied by L-gas in parts of the North-West region is assessed in the related North-West Gas Regional Investment Plan, based on the TYNDP CBA methodology and using data consistent with the TYNDP.
