Austria commissions its largest battery storage facility

Slovenian company NGEN has switched on what it claims to be Austria’s largest battery storage facility.

The project is located next a wood gas generator which opened in November 2024 in Fürstenfeld , southeastern Austria. The combined heat and power plant with 2 MW of electrical and 3 MW of thermal output is operated by Fürstenfelder Ökoenergie, a subsidiary of the Fürstenfeld municipal utility company.

In July 2024, Fürstenfelder Ökoenergie put a 10 MW solar farm into operation nearby the location, thus growing its solar fleet to around 14.8 MW.

In order to stabilize the grid, the municipality and the Fürstenfeld public utility decided last April to build the battery storage system with a power output of 12 MW and a storage capacity of 24 MWh.

NGEN, which is active in eight European countries both in planning battery storage systems and as a provider of energy system solutions, put the system together from 6 Megapack 2 XL systems from Tesla; each with an output of 1927 kW and storage capacity of 3854 kW (in the 2-hour storage version).

For NGEN, the project in Fürstenfeld is “just the beginning,” says Matija Dolinar, NGEN’s managing director for the Germany-Austria-Switzerland (DACH) region. “Our vision is to use intelligent battery storage systems to contribute to the energy transition throughout the DACH region and beyond.”
