Dear stakeholder,   

As part of the TYNDP 2026 cycle, ENTSOG is preparing to conduct system-level and project-level assessments.  

A public consultation during which we invite stakeholders to provide feedback regarding their key elements will be open between 9 - 31 March 2026. Draft guidance documents (Annexes D1, D2, D3) for these phases of the TYNDP will be published here by the start of the stakeholder consultation. 

Interested stakeholders are also invited to join a hybrid webinar on 9 March 2026, from 14:30 to 16:30 (CEST), during which the methodologies and assumptions covered by Annexes D1, D2, D3 to the TYNDP 2026 will be presented and stakeholder questions addressed.  

A separate, Q&A session, is scheduled to take place online on Monday, 23 March, 13:00 to 14:00 (CEST).
