Utility and network operators RheinEnergie and Bayernwerk have respectively started building and commissioned 7MWh battery storage projects in Germany.

Siemens has signed a letter of intent for the construction of a turnkey 100MW / 200MWh large-scale battery energy storage system (BESS) in Wunsiedel, northern Bavaria, Germany.

An inauguration event was held last week to unveil a new battery energy storage system combined with pumped hydro storage in Bavaria, Germany, after multi-national utility Engie completed work on the project.
