The global Battery Energy Storage System (BESS) Testing, Inspection and Certification (TIC) market is projected to grow from $0.66 billion in 2026 to $1.30 billion by 2032, representing a compound annual growth rate (CAGR) of 11.8%, according to a new MarketsandMarkets report.
The market is expanding alongside rapid deployment of utility-scale battery storage and renewable-plus-storage projects, which require comprehensive verification of system safety, operational reliability and regulatory compliance. Testing, inspection and certification providers are playing an increasingly important role throughout the BESS lifecycle, supporting battery manufacturers, system integrators, EPC contractors, utilities and project developers.
The report notes that demand has expanded beyond initial product qualification to include technical due diligence, fire-risk assessments, battery traceability, documentation support, commissioning validation and ongoing operational assurance. Growing scrutiny from regulators, insurers, lenders and grid operators is increasing the need for independent verification of battery storage projects before commercial operation.
Testing remains the largest service segment, accounting for approximately 50% of the market in 2026, reflecting its role across battery cell qualification, module validation, system integration, factory acceptance testing, site acceptance testing and commissioning. Testing also covers thermal runaway behaviour, electrical protection, electromagnetic compatibility, environmental resilience and grid interface performance.
Certification is expected to record the fastest growth during the forecast period as safety standards and regulatory requirements continue to evolve across global energy storage markets.
By sourcing model, outsourced TIC services account for roughly 65% of the market in 2026 and are forecast to increase to 72% by 2032. Project developers are expected to be the fastest-growing end-user segment, with an estimated CAGR of approximately 17%, driven by increasing requirements for supplier qualification, technical due diligence, commissioning support and grid compliance across expanding project portfolios.
Regionally, Asia-Pacific represents the largest BESS TIC market, contributing around 40% of global revenue in 2026, supported by strong battery manufacturing capacity and large-scale energy storage deployment. Europe is forecast to register the highest growth through 2032 as increasingly stringent safety regulations, traceability requirements and lifecycle compliance standards drive greater demand for independent testing and certification services.
The report identifies UL Solutions, Intertek Group plc, TÜV Rheinland, TÜV SÜD and DNV among the leading companies serving the global BESS TIC market. As battery energy storage capacity continues to expand worldwide, independent testing, inspection and certification services are expected to become increasingly important for ensuring safety, regulatory compliance and long-term operational performance.
