Manufacturing Supply Chain QA/QC for BESS Equipment Buyers While the majority 72%) of failures is known happen during construction, commissioning, or within the first two years of operation. In 2025, 19% of projects experience reduced returns due to technical issues and unplanned downtime. Integration, Assembly & Construction is a critical phase in BESS risk mitigation. Market Intelligence

Suppliers & Product Due Diligence

Supply Chain: A macro understanding helps mitigate purchase risks (geopolitical, shortages, etc.)

Factory Audit: assess a supplierʼs Manufacturing Process and the Quality Management System.

Regulations: recent and constantly evolving laws & regulations shape the market US tariff evolution, FEOC compliance)

Traceability Management System Audit: ensure the ability of the manufacturer to trace its own supply (impact of recalls, delivering specific products,...).

Pricing: Volatility of pricing is rising by many factors that should be known (balance between oversupply and tariffs) Technology: Newest technology evolutions are shaping BESS projects (modularization of BESS, new chemistry evolution)

Supply Chain Mapping: Validate that manufacturers can trace their supply chain (derisk the US CBP verification) ESG Management System Audit: Ensure the BESS is ethically sourced and respecting legislations.

Contracting Support Tendering Support / RFP Evaluation of suppliers relies on key aspects that depend on each BESS project. RFP templates can be standardized to qualify suppliers. Technical Contract Negotiation Support: the BESS industry is getting more and more specialized, technical support is necessary. QAP & Technical Exhibit: Testing of BESS products during manufacturing depends on the contractual limits set beforehand. In particular, the Factory Acceptance Test Scope review is key to ensure a functional BESS.
