On 17 October 2025, ENTSO-E publishes the draft list of electricity infrastructure projects to be assessed in the next edition of the Ten-Year Network Development Plan (TYNDP).  

The TYNDP 2026 draft project portfolio consists of 178 transmission projects and 49 storage projects. These projects were proposed by project promoters during the first submission window in April-May 2025. ENTSO-E has verified the compliance of all applications with the TYNDP 2026 admission criteria set out in the TYNDP 2026 Guidance for Applicants. 

Stakeholders and interested parties can explore the projects through the TYNDP 2026 project map. 

As next steps, a second submission window was open from 15 September to 15 October 2025, targeting projects in the ideation phase. All submitted projects will go through administrative and technical checks in November 2025. Over the course of 2026, all projects in the TYNDP 2026 portfolio will have their benefits assessed through a cost-benefit analysis. The results will be released with the draft TYNDP 2026 in late 2026.
