For each TYNDP, ENTSOG collects information on existing infrastructure capacities directly from TSOs (for transmission infrastructures) as well as from GIE1 (for LNG regasification terminals and storage facilities). For TYNDP 2020 the existing capacity was collected as of 1 January 2019.
In order to provide a holistic view of the European gas system over the next 20 years, it is important that all relevant infrastructure projects are incorporated into the TYNDP. ENTSOG has endeavoured to run an open and transparent data collection process, and actively encouraged project promoters to submit their projects.
As the submission of comprehensive project data is a critical prerequisite for the infrastructure analysis, ENTSOG provides a Project Data Portal open to all project promoters to support the process.
Only projects actively (re)submitted by promoters through the Project Data Portal have been considered in this edition of the TYNDP. This process ensures transparency and non-discrimination between projects. Ahead of the submission phase, to better support project promoters, ENTSOG provided a documentation kit 2 with a handbook on how to use the Project Data Portal and organised dedicated webinars for project promoters.
