ENTSO-E and ENTSOG release Innovation Roadmap for TYNDP Scenarios

On 27 February 2025 ENTSO-E and ENTSOG have released the Innovation Roadmap for TYNDP Scenarios. The Roadmap lists potential improvements to the scenario building process, proposed by TSOs, by the Scenarios Stakeholder Reference Group and by the scenario-building experts at ENTSO-E and ENTSOG. The Roadmap emphasizes the need for consistency between successive TYNDP cycles while accommodating emerging trends and expectations. Improvements in each cycle will be guided by prior evaluations and stakeholder feedback.  

The Roadmap includes a review of the innovations that were not implemented during the 2024 cycle, essential model fixes for improving the TYNDP 2024 model, and newly proposed innovations for the TYNDP 2026 scenario cycle. Additionally, this report lists further requirements from the Scenarios Stakeholder Reference Group, electricity and gas TSOs, and other stakeholders to complement and prioritize innovations for future cycles (TYNDP 2028 and TYNDP 2030).

Innovations in TYNDP 2026 Scenarios

The TYNDP 2026 cycle will be the first to fully comply with the ACER Framework Guideline, requiring already the implementation of several innovations in the scenario development approach. Given the compressed timeline for this cycle, there is a need to prioritize toolchain enhancements to ensure the timely development of scenarios. Therefore for 2026 the focus will be on addressing critical model issues identified thanks to stakeholder feedback on 2024 Scenarios, to ensure a high-quality baseline model.

Consultation and next steps

The Innovation Roadmap will be released for consultation along with the 2026 input parameters at the end of Q2 2025. Stakeholders feedback will be considered to further prioritize innovations for TYNDP 2028 and future scenarios cycles. ENTSO-E and ENTSOG will release an updated version of the Roadmap in early 2026.

The goal of this webinar is to provide external stakeholders updated information on the latest status of the 2026 TYNDP Scenarios. We will present the updated timeline for scenario activities, give an intermediate update about the innovations to be implemented in the 2026 cycle, and prepare stakeholders for the upcoming stakeholder activities including the public consultation & workshop on the input parameters. The webinar will also feature a presentation on the Scenarios Innovation Roadmap, which will be published shortly. Stakeholders are welcome to ask the Scenario Building Team questions and provide feedback on the 2026 TYNDP Scenarios process.

The detailed agenda will be communicated shortly.

Join our webinars to stay informed on the 2026 scenarios development

ENTO-E and ENTSOG will organise webinars at key steps of the project timeline, during the entire 2026 scenarios development process. The exact date, time and registration details of each webinar will be announced at the latest 2 weeks in advance.

• February 2025: Webinar on the state of play of the scenarios development process, innovation roadmap and scenarios development methodology
• May 2025, at the start of the public consultation on input parameters and methodologies: Webinar to present the material being consulted and answer stakeholders questions (Note: this webinar comes in addition to a workshop & roundtables)

The above timings are subject to changes, to adjust to evolutions of the scenarios development timeline.
