The OPENTUNITY project took part in Enlit Europe 2025, held from 18 to 20 November in Bilbao, Spain, joining one of the most important annual gatherings for the European energy community. As a leading event connecting policy-makers, DSOs, TSOs, researchers, technology providers, and innovators, Enlit offered the perfect stage for OPENTUNITY to present its progress and exchange insights with key stakeholders shaping the future of the energy transition.

Positioned in the EU Projects Zone, OPENTUNITY engaged with visitors at stand 5.F30–S02, sharing updates on the project’s technological developments, pilot activities, and the role of flexibility in enabling a more resilient and citizen-centric energy system.

Why Enlit Matters for OPENTUNITY

Participation in Enlit Europe is not merely a visibility exercise,it is a strategic opportunity to:

• show tangible progress on the technologies developed within the project,
• align with European policy priorities around digitalisation, flexibility and consumer empowerment,
• strengthen synergies with other EU-funded initiatives,
• and gather feedback from practitioners, system operators and industry leaders.

With the project entering its final operational phase, Enlit provided an ideal moment to demonstrate how the solutions developed over the past years are now being deployed and tested across Europe.

What OPENTUNITY Showcased at Enlit

At the stand, partners presented the 13 innovative technologies currently being integrated and demonstrated across the project’s four pilot sites in Spain, Switzerland, Slovenia, and Greece. These innovations revolve around:

• AI-powered state estimation and topology detection.
• Non-Intrusive Load Monitoring (NILM).
• Local flexibility markets and TSO-DSO coordination.
• Real-Time Thermal Rating and asset management tools.
• Building and Home Energy Management Systems (BEMS/HEMS).
• Data-sharing infrastructures for interoperable grid intelligence.

Visitors were able to explore how these technologies contribute to a more flexible, reliable, and consumer-engaged electricity system, one capable of addressing the growing complexity of distributed renewable generation, electrification, and variable demand patterns.

OPENTUNITY in the Enlit Conference Programme

In addition to the exhibition stand, OPENTUNITY was also featured in the conference sessions. The project delivered a presentation summarising its current status, innovations and expected impact, highlighting the following themes:

1. Physics-Informed Neural Networks for State Estimation

OPENTUNITY showed how AI models enriched with physical grid constraints can address traditional observability gaps, providing DSOs with more accurate, real-time insight into grid conditions.

2. Real-Time Topology Detection

The project demonstrated how physics-informed AI can identify unreported topology changes, an essential capability for maintaining reliable grid models and enhancing operational safety.

3. NILM for Enhanced Prosumer Engagement

The session explored how NILM algorithms can disaggregate consumption from smart meter data without additional hardware, enabling prosumers to understand their usage patterns and optimise behaviour.

4. Multi-Country Pilots Testing 13 Technologies

The presentation highlighted the uniqueness of OPENTUNITY’s four pilot environments—urban, rural, industrial and community-based—which together create a robust testbed for validating AI tools and flexible market architectures.

Key Takeaways Shared at Enlit

The session concluded with several key messages:

• AI-driven state estimation significantly enhances DSO capabilities by combining machine learning with power system physics.
• Topology detection powered by neural networks allows operators to correct grid records in real time.
• NILM provides scalable prosumer-level intelligence without requiring additional hardware, unlocking new services and engagement models.
• Diverse, multi-country pilot testing is fundamental to ensuring the scalability and robustness of new energy innovations.

Looking Ahead

With development completed and demonstration activities underway, OPENTUNITY is entering a decisive stage. The feedback and interactions generated at Enlit Europe 2025 strengthen the consortium’s ambition to deliver solutions that are not only technologically advanced, but also operationally relevant and aligned with Europe’s evolving energy landscape.

As the project moves towards 2026, the focus remains clear: deploy, validate, and pave the way for large-scale adoption of smart, AI-enabled flexibility and grid-management tools across Europe.
