This report sums up the findings of the STEERS project, which aims at aiding the implementation of system integration, the energy efficiency first principle, as well as the improvement of transparency and openness in the planning of energy networks in the European Union, and specifically in the Ten-Year Network Development Plan (TYNDP) process. In the project, the Copenhagen School of Energy Infrastructure (CSEI) has first assessed the planning of cross-border network infrastructure in Europe against the current state of knowledge. Subsequently, with the STEERS methodology (Brandstätt et al., 2023) the project team has proposed incremental changes to the TYNDP process in view of the requirements from the TEN-E regulation recast. Lastly, the feasibility of the altered methodology is assessed in this report. The suggestions and findings have been discussed throughout the project with and among stakeholders from the modelling community, the European network industry, policy makers and societal actors, to ensure their relevance and viability in practice.

Funded by the European Union via the STEERS project.
