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.

ENTSO-E and ENTSOG release their joint Draft Scenarios for TYNDP 2024
ENTSO-E and ENTSOG have released today their draft joint Scenarios, which will be the basis for the electricity and gas Ten-Year Network Development Plans (TYNDPs) 2024. These joint electricity, hydrogen and natural gas Scenarios are the fourth of their kind, building upon the successive scenario cycle since the first joint scenarios in 2018.
Scenarios evaluate the interactions between the electricity and gas systems, vital to delivering the best assessment of the infrastructure from an integrated system perspective. Supply and demand data collected from both gas and electricity TSOs are used to build ‘National Trends’, the central policy-based scenario, reflecting Member States’ energy and climate policies and recognising EU climate targets. The ‘Global Ambition’ and ‘Distributed Energy’ scenarios are developed as full energy scenarios (not limited to gas and electricity) and are built in line with the efforts of the EU-27 to reduce GHG emissions to 55% by 2030 and to net-zero by 2050.
