Over the first 14 months, the work starting to be dedicated to laying a robust foundation through comprehensive research and conceptual development. This phase involved a detailed study of the regulatory, social, and technological aspects influencing energy communities, with a special focus on the pilot countries. This analysis was pivotal in shaping the project's direction and identifying the unique challenges and opportunities within the energy community landscape. A significant achievement from this phase was the development of the "triangle" concept. This innovative framework encapsulates the interplay of social dynamics, technological advancements, and business & regulatory environments within ECs. By integrating these dimensions, the project established a holistic approach to understanding and addressing the complexities of energy communities. Furthermore, the EC journey has been designed and emerged providing and novel experiential and behavioural journey combining the operational pathway of an EC with the socio-behavioural progression within energy communities. In parallel, the first steps to the conceptual architectural mock-up of the digital arena marked a starting point in giving form to the technical developments in the project’s journey. The architecture was carefully crafted to ensure compliance with GDPR and other regulatory standards, setting a precedent for future digital solutions in this domain, ensuring robust cyber-security mechanisms. The project team undertook the development of intuitive, user-centric tools, providing a preview of the ecosystem of digital tools. These tools are being developed and will cover the EC journey, as well as the specific needs of different EC members or potential ones. The project’s solution will be implemented, tested and validated in the pilot of the project being real-world testbeds. Each pilot offers unique insights and contexts. The work for definition of their different use cases (scenarios) was given highly efforts to encompass their needs and goals.
