The Horizon 2020 project X-FLEX organised and chair this workshop together with other H2020 projects such as Synergy and e-Balance+, to present the ICT tools developed and demonstrated to increase the penetration of renewable energies in the European energy system, improving the sustainability and resilience of the grid. In this context, the replication synergistic roadmaps were presented for scaling-up of the project solutions to be applied on a large scale and in different real-world settings.
