JOANNEUM RESEARCH Presents Carsharing Flexibility at STS Conference Graz
Between May 4 and 6, 2026, our partner JOANNEUM RESEARCH (JR) represented the OPENTUNITY project at the STS Conference Graz 2026 in Austria. Organized by the Graz University of Technology, this event is a cornerstone for the scientific community to discuss the intersections of Science, Technology, and Society.
The Focus: Can Carsharing Support Grid Flexibility?
The core of JR’s participation was the presentation of their latest research titled: “Shared cars, flexible charging: When cost savings meet additional effort”. The study addresses a fundamental challenge in the energy transition: how to manage the volatility of renewable energy by utilizing the inherent flexibility of electric vehicles (EVs).
The research specifically explores whether integrating flexibility into a carsharing business model (such as the one operated by our partner Avant car in Slovenia) is viable from both a technical and social perspective.

Key Insights: Flex On-the-Go vs. Flex at Home
The study, based on a survey of over 950 Avant car customers, analyzed two main scenarios for flexible charging:
- Flex on-the-go: Charging the rented vehicle at suggested points during the trip to support the grid.
- Flex at home: Taking the rented vehicle home and allowing it to be charged flexibly overnight.
The findings were revealing:
- Motivation: Cost savings remain the primary driver for users (over 85% interest), followed by a desire to support sustainability and the energy transition.
- Barriers: For many users, the "additional effort" is a significant hurdle. Many feel that since they are paying for a mobility service, they do not want the extra complexity of managing charging schedules.
- Feasibility: The research suggests there is no "quick win," but flexibility models can succeed if cost savings are high enough and the additional effort for the user is kept to an absolute minimum.
Scientific Exchange and Future Outlook
For the OPENTUNITY project, participating in the STS Conference was a "great opportunity for exchange between applied research and colleagues with a more academic approach". This collaboration with Avant car allowed the team to access real-world field data, reducing sampling bias and ensuring that the project's innovations are grounded in actual user behavior.
By exploring these social and technical boundaries, OPENTUNITY continues to pave the way for a more integrated and decarbonized European electricity ecosystem.

OPENTUNITY Joins EUSEW 2025 to Showcase Innovation in Energy Flexibility
We are thrilled to announce that OPENTUNITY will be present at the EU Sustainable Energy Week (EUSEW) 2025, the EU’s flagship event on renewables and energy efficiency. This year’s edition takes place in Brussels, gathering energy stakeholders from across Europe to discuss policies, trends, and innovations shaping a sustainable energy future.
You can find us at Booth C5, 2nd Floor of the Charlemagne Building, where we will be presenting the latest advances from our project and engaging with other key players in the energy transition.
At EUSEW, OPENTUNITY will showcase its integrated approach to unlocking flexibility across the energy system through its four core pillars:
- OPENFLEX: enabling consumers and prosumers to offer flexibility through smart home/building tools, with live pilot testing underway in Slovenia, Spain, Greece and Switzerland. Recent progress includes the integration of EV charging infrastructure and HEMS/BEMS platforms, as well as the development of AI models for flexibility forecasting.
- OPENGRID: supporting DSOs and TSOs with innovative grid management solutions. Among the tools currently being validated in all four pilot countries is our State Estimation module — designed for improved real-time grid visibility — and low-cost thermal rating tools that optimize asset usage.
- OPENSPACE: building a Federated Data Exchange Infrastructure. We have recently achieved a major milestone with the completion of the architectural foundation and Proof-of-Concepts for trusted data sharing services.
- OPENABILITY: promoting interoperability through alignment with European standards. The updated Standardization Action Plan provides a clear roadmap for OPENTUNITY’s contributions to ongoing regulatory and technical standardisation efforts.
Our participation in EUSEW is more than just an exhibition — it’s a step toward reinforcing OPENTUNITY’s role in Europe's digital and sustainable energy transformation. Come meet us at the EUSEW to learn how we are building scalable, replicable and interoperable solutions that empower energy actors across Europe.
Join us at Booth C5 and discover how OPENTUNITY is helping to shape the flexible energy system of tomorrow.

OPENTUNITY innovations at the EUSEW 2024
03/06/2024
The OPENTUNITY project will participate in the Energy Fair of the European Sustainable Energy Week (EUSEW 2024) in Brussels from June 11th to 13th. Visitors can meet the OPENTUNITY team and learn about their innovations at booth C-28, located on the ground floor of the Charlemagne building. The stand will be hosted by ETRA, the project coordinator, on the morning of June 11th.
The OPENTUNITY innovations aim to revolutionise the energy sector by fostering a digital ecosystem that enhances energy efficiency in electricity grids, benefiting active consumers of all scales while significantly reducing energy costs.
Visitors can explore OPENFLEX, a technology designed for prosumers, and discover how the project’s partners have defined the flexibility market conditions for each pilot where these markets will be tested. Currently, they are working on allowing flexibility optimization algorithms to be tailored to specific market conditions.
Additionally, visitors can learn about OPENGRID, a solution for grid operators. They can see how technical developers, DSOs, and TSOs are collaborating to process the data provided by grid operators. This preprocessing is essential for developing OPENTUNITY innovations and training certain models.
See you there!
