FAVEOS SE: Joint Venture PowerWerker shows strong growth in fiscal year 2026

Hanover, September 4, 2026 – FAVEOS SE, a listed company focusing on large-scale battery energy storage systems (BESS) and grid infrastructure, is pleased to report strong growth for the joint venture PowerWerker, which was established last year in partnership with Biogas Service Tarmstedt GmbH.

PowerWerker secures orders totaling well over EUR 10 million in the first eight months of fiscal year 2026:

In the first eight months of fiscal year 2026, Powerwerker EPC GmbH has already secured numerous EPC contracts for large-scale battery storage systems with a total volume well in excess of EUR 10 million. All of these projects are scheduled for completion within the next nine months, and some are already under construction.

Demand for BESS-related EPC services remains consistently high; based on current inquiries, further dynamic growth is anticipated for the future.

"We are particularly successful in the 2.0 to 20.0-megawatt BESS power range thanks to our full-service offering - which encompasses planning, technical engineering, and plant construction, as well as subsequent BESS optimizing and long-term maintenance. We pursue a partnership-based approach characterized by collaboration on equal footing; our customers highly value this, alongside our decades of expertise in plant construction and project management," explains Dr. Holger Schmitz, Managing Director of Powerwerker EPC GmbH, regarding the successful order intake.

PowerWerker is a certified service partner of CHINT Power Systems:

Since the middle of the year, Powerwerker Service GmbH has been a certified service partner of CHINT Power Systems (CHINT), a major global provider of energy storage solutions. Furthermore, an agreement was reached with CHINT to establish a consignment warehouse for CHINT spare parts at Powerwerker’s headquarters in Westertimke (near Bremen), enabling a rapid response to customer needs.

Service for battery storage systems is an essential component for ensuring product longevity and optimal economic viability. Optimal system performance is only possible if scheduled maintenance is carried out, system components are checked for proper functionality, and operations are continuously monitored. As an experienced service provider, Powerwerker Service GmbH offers its customers maintenance packages for battery storage systems that are individually tailored to specific requirements.
