Before you leave for your summer holiday…

… let us recap all the highlights of TwinEU from the past 6 months. The project just hit the halfway mark: 18 months of work in the bank and 18 months of work still ahead. As you will see, the concept of the pan-European digital twin for the electricity system started to take shape as the building blocks of the system are falling into their places. We don’t keep these for ourselves, we present them whereever we can: our very own TwInsider Sessions webinar series, publications or on the social media - scroll down and you will see. Happy reading!

Huge milestone achieved by TwinEU at halfway

TwinEU held its 4th General Assembly on 4-5 June 2025 in Budapest, kindly hoested by our leading Hungarian partners the Budapest University of Technology and Economics and F4STER. As the meeting occured right at halfway of the project, we took stock of all the achievements so far which are going to be the basis of further advancement in the remaining time of TwinEU. The list of milestones is rather large already, but it is more the quality of them we are proud of. The main and newest ones:

1) Open Reference Architecture Finalized:

The Open Reference Architecture, the foundational „DNA” ofthe TwinEU system, is now ready. This includes the functional andnon-functional specifications needed for both the demonstrators and the TwinEUfederated system

2) Use Case Definition Complete:

A total of 50 use cases have been identified across 8demonstrators, showcasing a wide range of digital twinning applications forelectricity systems throughout Europe.

3) Pan-European Scenario Development Underway:

These use cases are now feeding into the development ofcross-border and pan-European scenarios that address strategic challenges.

4) Interoperability and Data Spaces:

The architecture ensures interoperability among digitaltwins, facilitating seamless integration with the European Data Spaces. It alsoenables cooperation among diverse actors in the energy value chain whilesupporting cross-border coordination and maintaining local operational autonomy.

Turning local digital twins into pan-European scenarios

In TwinEU’s most recent Deliverable, we identified all the digital twin use cases across our 8 demonstartors: we have 50+ of them, which are showing the full power of digital twins in action - enabling smarter grid planning, real-time operations, cyber resilience, flexibility and more.The task is now to find those use cases that can be scaled up to a European level, which is resulted in our initial list of cases:

• A pan-EU Grid Hosting Capacity Map
• Market co-optimization with dynamic flow-based auctions
• High accuracy forecasting for renewables
• Flexibility management and frequency support
• Enhanced system security and stability

TwinEU in the center of Digitalization

Relive our first TwInsider Session

• What do Digital Twins bring to the electricity system and the end-consumers?
• How is the EU policy landscape supports the adoption of Digital Twins
• What challenges does the industry face developing a pan-EU digital twin of the electricity system?

These were the questions we were looking for answers at our first edition of TwInsider Sessions together with representatives of the European Commission, ENTSO-E, the DSO Entity, the BRIDGE initiative and Horizon-projects DECODIT and DEDALUS back in February.

More sessions are coming soon - but don’t worry, we’ll invite you in time!

TwinEU & Science

TwinEU partners were quite busy on the scientific scene as well. Our recent publications are revolving around the current practices and requirements enabling data federation and its challenges, or demonstrating how digital twins can transform Europe’s energy system.

Digital Twins x Data Spaces

Enabling a federated ecosystem for digital twins in the energy sector is not an easy task, but the TwinEU project has a clear vision on it: implementing a digital twin federator – writes Ferdinando Bosco, our project partner from Engineering in its recent article for Enlit Insights.
