Predictable security across the entire lifecycle
guarantees tailored to your project objectives and operational requirements.
In utility-scale battery storage, it’s not just about technology and timelines—the decisive factor is how reliably the asset performs over many years. With our add-on service Comprehensive Product & Performance Warranties, we provide operators, investors, and lenders with a clear, bankable foundation: transparently defined performance commitments, unambiguous accountability, and predictable risk.
Product warranties and performance guarantees
Product warranties safeguard the quality and functionality of the components used—aligned with the respective system design and the project-specific operating conditions. In addition, performance guarantees define measurable operational targets, such as availability, capacity retention, or efficiency—always based on your individual project objectives and the intended use case (e.g., market participation, grid services, peak shaving).
The difference lies not only in what we do, but in how we do it.
Together, we define the applicable measurement and verification methods, the operating windows to be considered, and how deviations are handled. This results in guarantees that are practical in day-to-day operations and can be verified clearly in operation—without room for interpretation.
