Identifying and smartly controlling flexible consumers is essential, both to provide load-balancing on a system level and to prevent or resolve local network issues. Buildings equipped with local (PV) production, batteries (stationary or in the form of an electric vehicle) and electrical (heat-pump based) heating, cooling and hot water production systems are highly suitable for this. Utilising and valorising this flexibility also dovetails with the vision and ambition to engage prosumers as more active participants in the energy system by allowing them to valorise their available flexibility as a support service.
