In this report ENTSOG and ENTSO-E propose the scenario storylines for TYNDP 2024. This publication is an important foundation for further scenario building and quantification, which spans until the end of this year.
Next steps in the scenario building process are the following:
- ENTSOG and ENTSO-E will finalise the input parameters based on the public consultation and stakeholder roundtables and perform the quantification and modelling needed to build the TYNDP 2024 scenarios. With this modelling the (qualitative) storylines will be translated into fully quantified scenarios. A draft scenario report is expected to be published by the end of 2023 for the public consultation.
- ENTSOG and ENTSO-E will use all consultation feedback to refine and establish the final quantified scenarios to be used in TYNDP 2024. The final draft scenario report after public consultation is expected to be published in early 2024 and submitted to the ACER, MS and EC. Within three months of this submission, the ACER will provide its opinion on compliance of the scenarios with the Scenarios Framework Guideline and the EC will approve the scenarios report (or request to amend it) within three months after receiving the ACER opinion. The final scenarios feed into the TYNDP 2024 development process. The scenario datasets are used within the system needs assessment process and the cost-benefit analysis (CBA) for the PCI selection.
