FAVEOS SE concludes strategic framework agreements with leading battery optimizers enspired and Entrix

Hanover, December 15, 2025 – FAVEOS SE, a publicly listed company focused on large-scale battery energy storage systems (BESS), announced today that it has concluded strategic framework agreements with enspired and Entrix for the optmization of its own battery energy storage systems. At the same time, FAVEOS, through its joint venture PowerWerker GmbH, has also concluded framework agreements with the same partners to offer PowerWerker customers a comprehensive solution comprising EPC services, BESS-optimization, and operation & maintenance (O&M).

Key points of the agreements:

With these framework agreements, FAVEOS secures powerful multi-market optimization for its future BESS projects through the leading expertise of enspired and Entrix. The optimization is precisely tailored to the hardware used and the associated warranty conditions to achieve maximum performance and sustainable returns, combining AI technology with live-operation experience and in-depth market knowledge.

Through the joint venture PowerWerker GmbH – a 50:50 partnership between FAVEOS SE and Biogas Service Tarmstedt GmbH (BST) – the complete service portfolio is now covered for PowerWerker customers, from site analysis and planning to technical engineering and plant construction, as well as BESS-optimization and long-term maintenance (O&M).

“With these two partners, we are taking a big step: We are combining our project and system expertise with the highly specialized optimization and trading power of enspired and Entrix, and at the same time developing our joint venture PowerWerker GmbH into a full-service provider for large battery energy storage systems,” says Gerrit Janssen, CEO of FAVEOS SE.
