Lingen, Germany, December 2025 — AlphaESS, a global leader in energy storage solutions and a BloombergNEF Tier 1 certified manufacturer for Q4 2025, announced the successful delivery of its Aster 5000 tinklo masto energijos kaupimo sistema (ESS) to EPC partner Ecker for Stadtwerke Lingen, the municipal utility company. The entire project was completed one month ahead of schedule, once again demonstrating AlphaESS’s strong manufacturing capability, high-speed batch delivery, and end-to-end project execution capacity.
Highly Integrated Design Enables Rapid Deployment for Both Power Trading and Grid Frequency Regulation
Stadtwerke Lingen has been facing increased volatility in the electricity market and rising demand for reserve capacity. The municipal utility sought a simplified, highly integrated containerized ESS solution capable of supporting flexible power trading while providing frequency regulation to stabilize the grid.
To meet these requirements, AlphaESS supplied the Aster 5000, a 5MWh skysčiu aušinamas energy storage container. With its fully integrated 20-foot design, combining battery system, BMS, EMS, and fire-protection system in a single unit. The Aster 5000 significantly reduces onsite installation and commissioning time while enabling efficient large-scale deployment.
The system incorporates multi-layer safety protection from cell level to system level, including aerosol fire suppression, aerogel insulation, NFPA 68-compliant pressure relief, fire early warning and active protection, grid-side protection, and fault isolation. Each container undergoes a full factory acceptance test before shipment, a rigorous process rarely seen in the industry that ensures the highest delivery reliability. The platform also features cell-level bi-directional active balancing, which enhances performance and extends system lifetime by more than 10%, ensuring long-term reliability for utility-scale and large C&I applications.
Five Weeks to Germany, Two Weeks to Grid Connection: Industry-Leading Delivery Efficiency
The project arrived in Germany just five weeks after shipment and achieved grid connection within two weeks of arrival, completing the overall delivery one month ahead of schedule. Ecker highly praised the experience, emphasizing the system’s punctuality, stability, compact integration, and AlphaESS’s rapid response capability.
This deployment marks AlphaESS's first utility-sector ESS project delivered to a municipal utility in Germany.
The project once again validates AlphaESS’s excellence in global supply chain coordination, standardized manufacturing, and high-volume project execution.
Deep Presence in Europe: Local Service System Widely Recognized
With over ten years of market deeply rooted in Europe, AlphaESS has established a comprehensive local service network centered around its German technical service hub.
Driven by fast response times, professional technical support, and reliable product performance, AlphaESS has earned over 90% customer satisfaction in Europe, frequently recognized as “quick, professional, and highly recommended.” This strong regional service capability provides a solid foundation for AlphaESS's continued growth in the utility and large-scale storage sectors.
“The early delivery of the Stadtwerke Lingen project reflects AlphaESS’s collective strength in manufacturing, supply chain coordination, and project execution,” said Ted Tan, Head of Utility-Scale at AlphaESS. “Going forward, we will continue to leverage our expanding production capacity, highly integrated product platform, and reliable global delivery capabilities to provide greater value for Europe’s energy transition and Utility-Scale.”
Robust Manufacturing Capacity Pagalbas Global Delivery: Automated Production Continues to Expand
AlphaESS currently operates two automated module production lines with a total annual capacity of 8 GWh, capable of manufacturing 13-string single- and double-row skysčiu aušinamas battery modules designed for high-standard utility applications.
The company is also constructing a third automated production line, scheduled to begin operation in February 2026. Once completed, AlphaESS’s annual production capacity will increase to 14 GWh, further enhancing its global delivery capability.
This strategic capacity expansion ensures stable and scalable supply for skysčiu aušinamas products—including the Aster 5000—and accelerates deployment across utility and C&I markets in Europe.
