Currently, electricity network charges are typically levied independently of the actual grid utilization, which does not incentivize grid-friendly behavior. In the ongoing AgNes process by the Federal Network Agency (Bundesnetzagentur), a stronger temporal and spatial dynamization of network charges is being discussed. The goal is to make electricity consumption more flexible and to utilize the grid infrastructure more efficiently.
In the report “Potential Impacts of Time-Variable Network Charges”, EWI on behalf of the German Nature Conservation Ring e.V. analyzes the annual electricity costs of different household types under the current network charge system as well as under a time-variable tariff model. Additionally, it explores how load profiles in households with energy transition technologies (e.g., photovoltaic systems with home storage) could change.
