STREAM participated in the Interoperability and Flexibility session, where dr. Tomi Medved from the Laboratory of Energy Policy (University of Ljubljana), the Project Coordinator, presented the project’s objectives. He emphasised the importance of digital twins and harmonised data models as foundational tools for improving low-voltage grid observability and enabling future flexibility services. His contribution highlighted how enhanced data structures and modelling capabilities can help distribution system operators better understand and manage increasingly complex LV networks.

During the session, Tomi raised a key question shared across many EU-funded projects: what happens to operational data collected during demonstration activities once the project ends? Although projects generate large and valuable datasets, their reuse is frequently constrained by confidentiality requirements, competitive pressures and the high cost of measurement infrastructure. The discussion made it clear that, while consumer protection frameworks already exist, significant practical challenges remain regarding which data may be shared, under what conditions, and with which stakeholders. New business models demand new types of agreements, yet reaching such agreements in practice remains difficult.

The debate concluded with a compelling message: the biggest risk to flexibility development is inaction, whether caused by regulatory uncertainty or administrative delays.

Alongside the session, STREAM also welcomed visitors at its booth in the EU Projects Zone. The stand offered an opportunity to present the project’s goals, demonstrators and expected outcomes, and enabled engaging discussions with energy professionals, technology providers, regulators and representatives of other EU projects. These exchanges strengthened STREAM’s visibility and fostered valuable connections within the European energy innovation community.
