New investments are necessary for connecting isolated regions and for further integrating other areas. Unfortunately, some investment decisions have been de- layed because of a strong focus on the short term and of the absence of a clear long term vision for gas demand and supply. Failing to deliver these new infrastructures will leave the whole of Europe unprepared to face its continuously increasing import dependency. This report confirms the existence of projects which would support a more secure, competitive and sustainable energy future for Europe. These projects cover the construction of gas pipelines, interconnections, storages and LNG terminals as well as the development of new internal and external gas supplies. They will only materialize if decision-makers give appropriate signals to the market and focus on the implementation of existing regulations. On behalf of ENTSOG, I would like to thank all parties involved in the TYNDP process and I hope that this edition will see a large support of all stakeholders. I am confident that this TYNDP edition will prove to be both useful and stimulating. Now it is time for me to let you discover its findings. I would welcome your feedback on the report and its related production and assessment processes, which you can provide through our consultation process.
