It is becoming increasingly important for grid operators to monitor and control the electricity feed-in from decentral plants that produce electricity from renewable or other sources to guarantee the stability of the power grid. Legislation in some markets gives grid operators the opportunity to reduce the output of such plants in various steps. In parallel can e.g CHP’s be used to provide reserve capacity when this is needed. ZONOS enables the management and control of these plants with or without smart meter gateway. ZONOS provides the linking between grid control, MDM and smart meter gateway. Based on the energy generation and consumption, profits and losses can be shown to the end-customer. In addition, Apps for mobile devices provide a remote overview of the current energy generation and consumption. This is the ideal basis for service providers to offer new services regarding energy generation, consumption and management.
