The facility employs a StoraXe storage system supplied by Nürtingen-based ADS-TEC.

The system is housed in two containers and was delivered together with transformer, inverter, control system and climate control technology as a turnkey system within just a few months.

One challenge was transporting the system through the snow-covered, mountainous country-side with its small bridges and narrow roads to the installation site in Bruck next to the hydro plant of utility company Allgäuer Kraftwerke GmbH.

The new storage system is an independent initiative of the dedicated project company AllgäuSpeicher GmbH & Co. KG, a joint venture of Allgäuer Überlandwerk GmbH and enesto GmbH, which is responsible for operation of the storage system. Technical and commercial operations management are the responsibility of Allgäuer Kraftwerke GmbH. AllgäuSpeicher made the investment decision on economic grounds and the facility operates without subsidies.

ADS-TEC is the strategic partner of enesto, a project development company which operates large battery storage systems.
