ADS-TEC Energy nears permit for 4 GWh battery storage facility in Germany
ADS-TEC Energy expects to receive a building permit shortly for a planned battery storage facility at the Pulverdingen substation in Baden-Württemberg, Germany. With a planned output of around 1 GW and a storage capacity of 4 GWh, it would be one of the largest battery storage systems in Europe.
The permitting authority has confirmed that the application is complete, according to a press release from ADS-TEC Energy. The permit is a key requirement for concluding the financing and partnership agreements, and the grid connection is targeted for 2029. ADS-TEC doesn’t give a figure for the project’s cost, 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 electronics and software the company has developed in-house for more than 15 years. According to ADS-TEC, this reduces reliance on BMS suppliers, which are typically based in Asia, and keeps control over software, IT security and data local. German companies will supply the batteries, switchgear, transformers and extra-high-voltage equipment, but none are named.
“Energy is the foundation for everything we produce in Europe. Anyone who does not control the infrastructure for it gives up part of their ability to act. With our own technology and renowned European partners, we are demonstrating that Europe can plan, build and operate critical energy infrastructure on this scale on its own,” says Thomas Speidel, founder and CEO of ADS-TEC Energy.
ADS-TEC plans to sell a majority stake in the project company, preferably to a European energy company, and is also in talks with international infrastructure investors. The company will remain a long-term partner and provide technical services over the plant’s lifetime.
