From 16 June – 14 July and 1 – 29 July, ENTSO-E and ENTSOG invited all interested stakeholders to take part in the public consultations on the Draft 2026 TYNDP Scenarios input data and methodologies as well as Economic Variants development methodology, respectively. Taking place within the framework of the 2026 TYNDP Scenarios development cycle, the public consultations aimed at gathering feedback from key stakeholders to further strengthen the development and later implementation of the upcoming TYNDP Scenarios as required by Article 12 of (EU) 2022/869. The public consultations play a crucial role in achieving a meaningful exchange of findings and continuation of building the right forecasts for Europe’s energy and climate ambitions from today over 2030, 2040 up until 2050. In addition to the consultations, ENTSOG and ENTSO-E held a public workshop on 4 July 2025. This public workshop included a dedicated session for the draft economic variants methodology to thoroughly determine the first-time application of the economic variants’ methodology.
The input received from stakeholders is currently being reviewed by ENTSO-E and ENTSOG and will be included in the consultations’ summary report, which is anticipated to be published in the third quarter of 2025.
Welcome to the TYNDP 2026 Scenarios site //
ENTSO-E and ENTSOG are currently developing the TYNDP 2026 Scenarios. As underlying data, assumptions, methodologies and parameters concerning the Central Scenario and Economic Variants are currently being further developed, please read the 2026 Scenarios Stakeholder engagement plan for an overview of all planned activities to involve and inform stakeholders in the TYNDP 2026 Scenarios cycle. The plan is meant to be a living document, to be reviewed and potentially updated to adjust to possible evolutions of the TYNDP 2026 Scenarios development timeline. In addition to the engagement plan, the detailed TYNDP 2026 Scenarios Timeline outlining developments of each deliverable is available in the download section of this website.
Join our webinars to stay informed on the 2026 scenarios development
ENTSO-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.
The timings are subject to changes, to adjust to evolutions of the scenarios development timeline.

2026 scenarios stakeholder’s engagement timeline
TYNDP Scenarios Innovation Roadmap
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 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.
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.
