ADS-TEC Energy nears permit for 4 GWh battery storage facility in Germany

What happened

ADS-TEC Energy expects to receive a building permit shortly for a planned battery storage facility at the Pulverdingen substation in Baden-Württemberg, Germany. The facility is planned with an output of around 1 GW and a storage capacity of 4 GWh, which would make it one of the largest battery storage systems in Europe. The permitting authority has confirmed the application is complete, according to a press release from ADS-TEC Energy. The permit is a key requirement for concluding financing and partnership agreements, and grid connection is targeted for 2029. ADS-TEC did not give a project cost figure but says facilities of this size typically cost from the high hundreds of millions of euros up to around EUR 1 billion. The batteries will run on ADS-TEC's own battery management system, with in-house developed electronics and software of more than 15 years; German companies will supply the batteries, switchgear, transformers and extra-high-voltage equipment, but none are named. ADS-TEC also plans to sell a majority stake in the project company, preferably to a European energy company, and is in talks with international infrastructure investors, while remaining a long-term partner providing technical services over the plant's lifetime.
