The infrastructure to produce, transport, store and distribute energy is inarguably one of the most critical assets for a modern society and a backbone for its economic activities, welfare and stability.Rendering the European energy grid smarter is necessary for improving efficiency and increasing the share of intermittent renewable energies. It enables consumers to better manage their consumption and to produce and store their own energy. Digital solutions are becoming central to keeping the lights on and the grid balanced. They are a boon to network operators and "prosumers" alike.
