Last 7–10 October 2025, OPENTUNITY was represented at one of the most important annual events in the renewable energy sector, the Renewable Energy Grid Integration Week 2025, which hosted the 24th Wind & Solar Integration Workshop in Berlin. The event, organised by Energynautics, gathered more than 420 participants from 38 countries, bringing together leading experts, researchers, and industry representatives to discuss the challenges and innovations shaping the future of renewable energy integration.

Sharing Insights on Flexibility and Data Interoperability

Georgia Eirini Lazaridou from HEDNO presented a joint paper prepared by HEDNO, IPTO, and NODES, highlighting key findings and progress from the Greek Pilot of the OPENTUNITY project. The presentation focused on the importance of flexibility as a cornerstone for maintaining grid stability and reliability in systems with high renewable energy penetration.

The paper explored how Transmission and Distribution System Operators (TSOs and DSOs) can coordinate flexibility procurement through secure, transparent, and interoperable data exchange mechanisms, an approach that is central to OPENTUNITY’s mission.

Flexibility: A Core Enabler for the Energy Transition

A recurring message throughout the workshop was clear: flexibility is the key enabler for addressing the operational challenges of modern power systems. As renewable energy sources like wind and solar become dominant, grid operators must adapt to manage variability and uncertainty in both demand and generation.

To achieve this, it is crucial to:

• Strengthen data exchange frameworks that are secure and interoperable,
• Encourage the participation of diverse flexible assets (such as distributed generation, storage, and demand-side response), and
• Support market-based operation models that reward flexibility contributions.

These topics are at the heart of OPENTUNITY’s ongoing work, particularly within the Greek Pilot, where HEDNO and IPTO are testing new coordination mechanisms for flexibility services and demonstrating their real-world potential.

Aligning Research and Practice

OPENTUNITY’s participation in the workshop reaffirmed how closely aligned its objectives are with the broader research and innovation community working on renewable integration. The discussions and feedback gathered in Berlin will help guide ongoing activities in the project, especially in refining data interoperability frameworks, flexibility market design, and grid operation strategies.

As the project moves into its final phase, these insights will play an important role in shaping the next generation of smart, flexible, and decarbonised European power systems.
