With more than 200,000 electricity storage systems currently installed in Germany and an installation rate of around 65,000 units in 2019, electrical energy storage systems are becoming increasingly important. They offer an attractive opportunity to reduce energy costs. With regard to the planning and optimization of decentralized electricity storage systems, there is a need for planning tools that, unlike commercial offers, provide manufacturer-independent access for planners and installers to impart and further develop the relevant knowledge.
The new VDI 4657 series of guidelines is intended to close this gap in future. Together with the BVES Bundesverband Energiespeicher Systeme e.V., the Emden/Leer University of Applied Sciences, the Berlin energy service provider denersol and the Jülich Research Center, the VDI is launching the project "Planning and integration of energy storage systems in building energy systems" with a focus on "Electrical power storage" ("PIEG-Strom"). In addition to creating the VDI guideline, the project partners are developing an open source tool for designing electricity storage systems.
