Battery Charts is a development of Jan Figgener, Christopher Hecht, and Prof. Dirk Uwe Sauer from the Institutes ISEA and PGS at RWTH Aachen University. With this website, we offer an automated evaluation of battery storage from the public database (MaStR) of the German Federal Network Agency. For simplicity, we divide the battery storage market into home storage (up to 30 kilowatt hours), industrial storage (30 to 1,000 kilowatt hours), and large-scale storage (1,000 kilowatt hours and above).

This page is the supplementary material of the detailed market analysis in our current publication. The graphics and data on this page are licensed under CC BY 4.0 and may be used with credit to the authors and license (see “Citation” tab).

In total, some gigawatt hours of stationary battery storage is reported by now in Germany. The largest share of this is accounted for by home storage, which carries the overall market. Large-scale storage forms the second largest market ahead of industrial storage. For comparison: The national pumped-hydro storage systems have a total energy of 39 gigawatt hours.
