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 utility-scale energy storage system (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.
El diseño altamente integrado permite una implementación rápida tanto para el intercambio de energía como para la regulación de la frecuencia de red
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 liquid-cooled 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.
Cinco semanas hasta Alemania, dos semanas hasta la conexión a la red: Eficiencia de entrega líder en la industria
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.
