N2 - In the context of the increasing share of renewable energies in electricity production and tendencies towards decentralized generation of power, energy storage systems are considered a key technology since they are capable of balancing fluctuating (renewable) generation and demand. However, the technical and economical evaluation of energy storage applications strongly depends on specific use cases and related business models are still not available. To approach this issue for the case of electricity storage systems, this work examines existing cases of electricity storage use and conducts a case study in an industrial zone in France in order to better understand storage valorization. The analysis of existing cases of use allowed the deployment of electricity storage to be categorized in three groups. These groups are the non-grid-connected zones, grid-connected zones with intermittent electricity production and grid-connected zones without intermittent electricity production. The second part of this work consists of a technical and economical evaluation for the application of an electrical storage system in an industrial zone in France. This case study can be assigned to the category of grid-connected zones without intermittent electricity production since it consists of industrial sites without any local renewable electricity generation. There are two value streams generated from the storage system: Electricity is purchased and stored during off-peak hours to reduce purchases on peak hours. Additionally, the demand rate which is calculated based on the peak demand per month is optimized. The results of the case study demonstrate that in the configuration chosen and under current conditions the application of an electricity storage system is not profitable in this area.
