CrowdNett is a network of home batteries that can be charged or discharged remotely. This network enables network managers, such as TenneT, to access reserve capacity in order to keep the electricity network in balance. Eneco is responsible for ensuring a streamlined process.
The home batteries in CrowdNett’s network must always have an available continuous output. This output is a constant frequency of 50Hz. If the electricity grid dips below 50 Hz, the Powerwall starts supplying capacity. If the electricity grid rises above 50Hz, the Powerwall stores the energy. This is a big added advantage because, unlike coal-fired plants that need time to scale up or scale down, home batteries react immediately.
