A household just outside Berlin has become the recipient of the 100,000th grid-connected residential battery energy storage system in Germany.

Parliamentary State Secretary at the Federal Ministry for Economic Affairs and Energy, Thomas Bareiß attended an official event to mark the system’s commissioning in Eichwalde. Bareiß hailed the event as an “important milestone” that Germany has reached in its energy transition – referred to domestically as the Energiewende.

The politician said that since 2013 battery costs have fallen by over 50%, making the Energiewende more affordable and expanding “flexibility options” open to grid operators for intelligent load management, while bolstering energy security.
