In recent years, the European Commission and EU countries have set up numerous large-scale pilot projects to contribute to the digitisation of the energy industry across Europe and beyond. The most important goals of this endeavour are reaching a common energy data space to facilitate infrastructure planning and monitoring, empowering citizens by providing them with tools for participation in energy markets, supporting research and development of digital solutions, improving cybersecurity of the energy sector, and supporting the adoption of climate-neutral solutions for the ICT sector. In this panel key projects and services will be presented that move towards a sustainable and digital energy world by exploiting data sharing. The renowned experts and market drivers will show up their approaches and innovative solutions by presenting: Insights to a R&D project about secure smart grids in Germany that is focusing on FIWARE based smart energy solutions while facing Redispatch 2.0 and business modelling challenges. References on how a local utility works together with research institutes and energy ICT companies to realise a building block called “Energiewende” - the transformation of the energy systems towards renewables. The efficient use of data in building energy systems to achieve scalable solutions. Main highlights and strategies of European projects: French Data Network and Enershare. Showcases on how FIWARE building blocks enable the data sharing of energy communities: first insight to the background of energy communities and a proof-of-concept for using the FIWARE context broker as the coordinator of an energy community.
