Interfacing Open Energy System Planning with ENTSO models and contributing to the TYNDP

Partner: European Network of Transmission System Operators for Electricity (ENTSO-E)

Funders: Breakthrough Energy, Google.org, European Climate Foundation, Quadrature Climate Foundation

The Ten-Year Network Development Plan (TYNDP) is essential for shaping the future of European energy. However, the process used by 40 system operators to align national energy strategies and investment priorities is often complex and difficult to replicate. This complexity can hinder collaboration, slow down the integration of new technologies, and make it harder for stakeholders to make informed, data-driven decisions. This, in turn, impacts the transition to a more sustainable and interconnected European energy system.

The innovation project, in collaboration with ENTSO-E, aims to address these challenges by developing an open-source sector-coupled network expansion model built on PyPSA-Eur for scenario building and cost-benefit analysis, fully compatible with the TYNDP workflow. This open-source approach will make TYNDP results easily reproducible and adaptable, enabling faster, more collaborative, and more efficient energy planning for Europe's sustainable energy transition.

Project Aims

Implement a complementary open-source toolbox in the TYNDP planning process.

Streamline planning with one integrated tool using consistent assumptions across scenario building and cost-benefit analysis.

Ensure credibility through validation against official 2024 TYNDP results.

Enable long-term use through comprehensive training and knowledge transfer.
