ADS-TEC Energy PLC (NASDAQ: ADSE) (the "Company"), a global leader in battery-based energy storage and fast-charging systems, today announced plans to implement one of the world's largest battery energy storage projects (BESS). Located in southern Germany, the project is designed to deliver 1 GW of output with a storage capacity of approximately 2 GWh, marking a significant milestone in the company's history and strengthening the foundation for a stable and sustainable energy system.

Breaking New Ground in Large-Scale Energy Storage
Development of the large-scale BESS project began nine months ago. With a planned capacity of nearly 2 GWh, the facility when completed will have the ability to cover the daily energy consumption of approximately 250,000 single-family homes. The project has already received unanimous approval from the local city council, while the transmission system operator (TSO) has provided the positive assessment for the extra-high voltage grid connection.
Project development and financing are expected to be finalized by mid-2026, with commissioning scheduled for 2029, subject to receipt of regulatory approval. Once operational, the facility is expected to operate for several decades. The BESS will be supplemented by double-digit megawatt peak (MWp) large-scale solar panel installations for on-site consumption. The combination of BESS and photovoltaics (PV) not only advances the energy transition but also enhances the economic performance of the entire project.
Expanding ADS-TEC Energy's Role
ADS-TEC Energy will oversee the entire project lifecycle – including planning, financing, implementation, operation, and maintenance. With more than 15 years' expertise in lithium-ion storage technologies and a proven track record of building frequency regulation plants successfully connected to the grid for over a decade, the company is well-positioned to ensure successful delivery.
"This project represents a turning point for our company. Beyond implementing one of the world's largest BESS projects, we are laying the groundwork for an energy system that unites security of supply with sustainability. With extensive experience, a highly capable team, and the right partners, we are exceptionally well-prepared to seize this opportunity, This is an incredible flagship project for critical infrastructure, developed and operated by ADS-TEC Energy," said Thomas Speidel, CEO and Founder of ADS-TEC Energy.
Financial outlook
The Company believes that the project provides substantial potential from both an operational and investor standpoint. It expects to generate significant revenues. The operation and commercialization of this large-scale storage facility will give ADS-TEC Energy access to both the European wholesale energy market, the capacity market and all of the physical grid services.
Based on 2024 market data, a comparable storage facility would have generated revenues exceeding €230 million in 2024 (see chart below, annual revenue per MW), benefiting strongly from participation across both markets. The Company believes this underscores the attractive yield potential of the project and its importance in supporting Europe's energy transition.
