The current international situation makes the process of energy transition more critical for Europe than ever before. It is a key requirement to increase the penetration of renewables while aiming at making the infrastructure more resilient and cost-effective. In this context, digital twins (DT) build a key asset to facilitate all aspects of business and operational coordination for system operators and market parties. It is of fundamental importance to now start a process of agreement at European level so not to develop isolated instances but a federated ecosystem of DT solutions. Each operator should be able to make its own implementation decisions while preserving and supporting interoperability and exchange with the remaining ecosystem. Exactly this is the vision of the TwinEU consortium: enabling new technologies to foster an advanced concept of DT while determining the conditions for interoperability, data and model exchanges through standard interfaces and open APIs to external actors. The envisioned DT will build the kernel of European data exchange supported by interfaces to the Energy Data Space under development. Advanced modeling supported by AI tools and able to exploit High Performance Computing infrastructure will deliver an unprecedented capability to observe, test and activate a pan-European digital replica of the European energy infrastructure. In this process, reaching consensus is crucial: the consortium therefore gathers an unprecedented number of actors committed to achieving this common goal. The concepts developed by TwinEU span over 15 different European countries with a continuous coverage of the continental map. Demos will encompass key players at every level from transmission to distribution and market operators, while also testing the coordinated cross-area data exchange. The consortium also includes relevant industry players, research institutions and associations with a clear record in developing innovative solutions for Europe.

The overall vision of FORTESIE is to design, demonstrate, validate and replicate innovative renovation packages in the building industry with Smart Performance-Based guarantees and financing, aiming at Efficient, Sustainable and Inclusive Energy (ESIE) use to accelerate the Renovation Wave in Europe. The renovation packages will combine state-of-the-art construction materials and technologies components (prefabricated facades, BIPV, heat pumps, etc.), innovative digital technologies for measurement and verification, and attractive financing (e.g. contractual frameworks for smart performance guarantees, financing mechanisms, engagement techniques, green-euros, etc.), to raise the overall EPC value proposition. The renovation packages will be tailored to specific target groups needs and optimised to improve the ESIE performance considering energy, CO2 and comfort. Each package will be demonstrated and validated in real life use cases and customised for replication in all other partner countries for immediate market take-up. Methodologies from Social Sciences and Humanities (SSH) will be adopted for: a. the creation of collaborative business models that boost the Renovation Wave by considering all stakeholders’ value and revenue streams, b. novel incentivisation and behavioural change models that aim to stimulate long term engagement with focused interactions to adopt green behaviour c. the incorporation of a digital currency, green-euro, (€G) for financing, rewarding and creating an inclusive /collective narrative in the fight against climate change d. the collection of feedback for recommendations to policy and business stakeholders, e. Mapping and understanding the complex interplay between the different stakeholders to deliver an engagement strategy across the value chain.These demonstrations will potentially constitute the green-euro as a retail Central Bank Digital Currency (CBDC), hence revolutionising the financing of renovation approaches. An online marketplace, will be offering first level advice, directing consumers through the value chain of stakeholders and facilitating access to these “packaged” renovation services.
