Construction of the world’s first modular large-scale battery storage system begins in Aachen

E.ON is investing in a broad spectrum of future technologies for energy storage
Today marks the official start of construction of the modular large-scale battery storage system M5BAT on the premises of RWTH Aachen University. Storage systems like this represent an important building block for the expansion of renewable energies, as they make a significant contribution to system stability. They also open up a broad range of areas of application. The planned power class of five megawatts and the high level of modularity – whereby different battery technologies are combined with one another – make the so-called “M5BAT” (Modular Multimegawatt, Multitechnology Medium-Voltage Battery Storage System) a world-first. ….
