The UIC Traction Energy Settlement Workshop 2025, held both at the UIC headquarters in Paris and online, was coordinated by Daniele Arena (UIC) and Philippe Stefanos (UIC Sustainability Advisor). The workshop brought together experts and stakeholders from across Europe to exchange insights on the future of energy metering, data exchange and settlement in the railway sector under IRS 90930.
Dag Storhaug from Bane NOR presented the fundamentals of IRS 90930, a standard structured around five core pillars: roles, functions, data, data transfer and processes. He highlighted the ongoing work of the Maintenance Working Group, which brings together UIC experts to regularly review and update the IRS and its appendices. Recent work includes updates to master data content and “max power” calculations for traction units.
Several practical examples illustrated the implementation of IRS 90930 across borders:
- The ÖBB–SZ Infrastruktura cooperation on train-run data exchange
- Eress’s Erex Exchange & Settlement system
- The EMS Norm EN 50463-2017 French DCS running from France to Germany
Insights from Harald Wiebel (DB Energie) and Sinziana Carloganu for RTE’s DECOFER showcased practical models for third-party access to national traction energy grids ensuring fair, transparent and high-quality data for all RUs and IMs.
Bart Van der Spiegel (Infrabel) presented the evolving European framework, including the Technical Specification of Interoperability (TSI) and the main changes to EN 50463.
The ERA AS-03 study, introduced by Giacomo Potenza and Esteban Coito Gonzalez (European Union of Railways – ERA), examined on-ground energy data collection and settlement systems under the 2024-2030 TSI mandate. The final report is expected by the end of 2025.
Bart Van der Spiegel and working group members Gregor Hribar, Sinziana Carloganu, Darren Dang, Marin Zwetkow, Emily Raijmakers, Štěpán Jirout, Gunn-Helene Krögstad, Dag Storhaug, Rami Huovinen, Jan Winter and Ellin Petersen helped facilitate a poster session that was held in the morning.
An interactive session in groups was organised for the afternoon, allowing experts to discuss the harmonisation of EMS acceptance and reverification, addressing pain points, challenges and the energy market’s expectations for data quality.
