What is it about?
Today, ACER publishes its Opinion on the 2024 draft TYNDP, submitted by ENTSO-E to ACER in April 2025. The Opinion also includes recommendations on ENTSO-E’s Infrastructure Gaps Identification report, developed within the framework of the TYNDP 2024.
What is the TYNDP and why is it important?
Cross-border electricity infrastructure is key to interconnecting Europe’s electricity markets, making it easier to share electricity across countries. This is important to integrate more renewables onto the grid and achieve ambitious decarbonisation goals.
Every two years, European grid operators submit their draft EU-wide ten-year network development plan (TYNDP) to ACER for its opinion. Given the scale of infrastructure needs and that related costs are expected to make up a growing share of electricity bills, having a robust and fit-for-purpose TYNDP is key to efficient grid development.
What are ACER’s main findings and recommendations on the 2024 draft TYNDP?
- ACER welcomes the progress made so far and acknowledges ENTSO-E’s continued effort to introduce improvements in each new edition of the TYNDP.
- ACER finds that the 2024 draft TYNDP generally contributes to the objectives of non-discrimination and effective competition but does not sufficiently contribute to the efficient functioning of the electricity market or ensure an adequate level of cross-border interconnection open to third-party access.
- ACER also identifies areas for improvement in terms of timeliness, transparency and granularity of the information provided.
What does ACER recommend to ENTSO-E for future electricity TYNDPs and Infrastructure Gaps Identification reports?
- Ensure timely submission of the TYNDP and of the Infrastructure Gaps Identification report, by addressing the structural causes of delays.
- Enhance transparency and data quality by conducting substantial consultations.
- Strengthen the medium-term focus, by prioritising studies over a 10- or 15-year horizon.
- Improve transparency and consistency of the information on existing grids and projects.
- Base the modelling of the electricity network on appropriate grid information at all stages.
- Publish detailed information on infrastructure gaps, including those related to network constraints within Member States.
- Fully comply with ACER’s Scenario Framework Guidelines and its Opinion on ENTSOs’ draft TYNDP 2024 Scenario Report.
Next steps
ENTSO-E is asked to implement ACER’s recommendations both to finalise the 2024 TYNDP and to further improve its upcoming editions.
