AI Innovation from OPENTUNITY Takes the Stage at ENLIT 2025
At ENLIT Europe 2025, OPENTUNITY once again demonstrated its commitment to shaping the future of smart grid innovation. This year, the spotlight was on the work of Elektro Ljubljana, whose contribution showcased how artificial intelligence can dramatically improve reliability and performance in low-voltage distribution networks, an area where fault detection remains notoriously challenging.
The presentation, delivered by Dr. Klemen Nagode during the session “AI in Practice – Part 2”, offered an insightful look at a rapidly evolving field where data, algorithms, and operational expertise converge to strengthen tomorrow’s electricity distribution systems.
Bringing AI Into the Heart of Low-Voltage Operations
Unlike transmission grids, low-voltage networks are vast, complex, and traditionally less monitored, making it difficult for operators to quickly identify emerging issues. Faults such as bad neutral contacts, voltage anomalies, or early signs of component degradation often remain invisible until they escalate into service interruptions.
To tackle this, Elektro Ljubljana developed an AI-based anomaly detection system designed to uncover these hidden issues early on. The solution analyses a rich blend of data sources, smart meters, protection relays, historical fault records, and state estimators, to detect patterns that signal abnormal behaviour.
Behind the scenes, the team carried out extensive feature engineering, model training, and data validation, using advanced machine learning techniques such as weighted K-nearest neighbors with optimised parameters. The result is a system capable of identifying subtle anomalies with remarkable speed, supporting predictive maintenance and reducing operational uncertainty.
How OPENTUNITY Strengthens This Work
The development does not stand alone, it is actively supported by several tools created within the OPENTUNITY project. Among them:
- Fuse-burn detection modules offering early indicators of device or line distress
- Real-Time Thermal Rating (RTTR), enabling dynamic monitoring of conductor temperature and loading
- Failure forecasting tools, combining short-term and long-term risk modelling
- Advanced asset management systems, providing a structured view of network conditions
These components bring additional layers of insight to the anomaly detection framework, helping enrich datasets, refine machine learning models, and improve the robustness of the overall solution. This illustrates OPENTUNITY’s mission: to build interoperable, complementary tools that elevate grid management through digital intelligence.
A Human–Machine Partnership
One of the strongest points highlighted in the session was the importance of collaboration with field maintenance teams. Real-world verification of model predictions, by technicians working directly on the network, provided essential feedback, allowing the algorithms to evolve beyond theoretical accuracy and into practical, operational usefulness.
This iterative loop between AI systems and human expertise created a powerful validation mechanism, ensuring that the tool performs reliably in diverse, real-life scenarios.
Why This Matters for the Future of Grid Operations
This work marks an important step forward for European distribution system operators. By combining AI, operational data, and domain expertise, the approach significantly improves fault detection capabilities in low-voltage networks, historically one of the most difficult areas to monitor.
It also demonstrates the potential of the solutions being developed in OPENTUNITY: tools that are not only innovative but also applicable, scalable, and designed to support day-to-day decision making.

OPENTUNITY Participates in the Energy Nexus Cluster Internal Workshop in Bilbao
On 17 November 2025, OPENTUNITY took part in the Energy Nexus Cluster Internal Workshop, a technical and highly collaborative event held in Bilbao (Spain) and hosted by Tecnalia. The workshop brought together representatives from several EU-funded, energy-related research and innovation projects, creating a unique forum to deepen discussions, exchange expertise, and explore shared challenges across the sector.
A Collaborative Space for Knowledge Exchange
The objective of the workshop was clear:
to connect experts from the scientific community and industry, enabling cross-project learning and joint reflection on today’s most pressing topics in the energy transition.
Participants engaged in dynamic sessions where insights from ongoing European projects were openly shared. The workshop’s structure encouraged not only the presentation of technical results but also active dialogue and debate, fostering a space where problems could be examined collectively and solutions co-created.
OPENTUNITY’s Contribution: Insights Through Presentation
ETRA, representing OPENTUNITY, contributed to the workshop through a dedicated presentation, offering an overview of the project’s approach, challenges, and ongoing achievements. The audience, composed of researchers, technology experts, and industry representatives, showed strong interest in OPENTUNITY’s work on grid flexibility, digitalisation tools, and AI-enabled solutions.
The relevance of the workshop topics to OPENTUNITY’s scope made the exchanges particularly valuable, feeding reflection on interoperability, scalability, and the practical deployment of innovative technologies.
Main Takeaways and Conclusions
One of the workshop’s defining features was its high level of participation and interaction. Rather than a sequence of monologues, the event evolved into a genuine knowledge-sharing forum, where each presentation sparked discussions, questions, and real collaborative thinking.
Key conclusions include:
- The event confirmed the importance of cross-project dialogue to align approaches and accelerate innovation.
- Discussions directly addressed themes crucial for OPENTUNITY, including digital tools for grid management, flexibility markets, and AI-driven optimisation.
- The workshop environment strengthened connections with other EU energy projects, opening doors for future synergies and cooperation opportunities.
Driving Innovation Together
The Energy Nexus Cluster Internal Workshop once again demonstrated the value of bringing together diverse actors working toward Europe’s clean energy objectives. For OPENTUNITY, it was an excellent opportunity not only to present ongoing progress but also to gather insights that will help shape the project’s next steps.
Through active participation and knowledge-sharing, OPENTUNITY continues to contribute to a more interconnected, innovative, and resilient European energy ecosystem.
OPENTUNITY Showcasing AI-Driven Innovations at Enlit Europe 2025
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

OPENTUNITY Completes Its Second Project Review in Granollers
The OPENTUNITY consortium recently met in Granollers (Spain) for its Second Review Meeting with the European Commission. This milestone marks an important step in evaluating the progress achieved over the past 16 months and preparing for the final phase of the project.
The review showcased substantial advancements in technology development, pilot deployment and flexibility market demonstration across Europe. The feedback from the European Commission was very positive, reinforcing the consortium's confidence in the relevance and quality of the work performed so far. At the same time, partners acknowledge that the upcoming months are crucial to complete all planned demonstrations and validate the project’s full potential.
A deep dive into the Spanish pilot
