BESS TIC Market

The global Battery Energy Storage System (BESS) Testing, Inspection, and Certification (TIC) market is expected to grow from USD 0.66 billion in 2026 to USD 1.30 billion by 2032, at a CAGR of 11.8% during the forecast period. Growth is supported by rising utility-scale and renewable-plus-storage deployment, which increases demand for battery safety testing, thermal-runaway assessment, fire-risk evaluation, grid-code compliance, and FAT/SAT and commissioning validation. BESS manufacturers, system integrators, EPC contractors, utilities, and project developers require independent assurance across battery cells, modules, racks, PCS, BMS, EMS, enclosures, and grid interfaces. Stricter safety regulations, lender and insurer scrutiny, and increasingly complex grid-integration requirements are expanding demand beyond initial product qualification toward certification, technical due diligence, supplier audits, digital documentation, and lifecycle performance assurance. As project scale and system complexity increase, specialist TIC providers are strengthening capabilities in large-scale fire testing, system certification, independent commissioning, and operational safety verification.

Major companies in the Battery Energy Storage System (BESS) Testing, Inspection, and Certification (TIC) market include UL Solutions (US), Intertek Group plc (UK), TÜV Rheinland (Germany), TÜV SÜD (Germany), DNV (Norway), and CSA Group (Canada). Two strategies primarily shape competition. The first is the expansion of BESS-specific technical capabilities, with providers strengthening their offerings in thermal-runaway and fire testing, product and system certification, grid performance validation, factory acceptance, commissioning, and independent technical due diligence. This enables providers to support customers from battery and system qualification through project delivery and operational assurance. The second is strategic partnerships and collaborations. TIC providers collaborate with battery manufacturers, BESS OEMs, technology firms, project developers, and energy-storage specialists to access specialized testing infrastructure, integrate digital assurance tools, and expand their role in product qualification, supply-chain assurance, grid integration, and lifecycle monitoring. For example, UL Solutions collaborates with CATL on battery and energy storage testing, while TÜV Rheinland has partnered with energy storage technology companies to support product validation and meet market access requirements.

UL Solutions is a leading BESS TIC provider, pursuing a strategy of expanding high-value safety and compliance services across the battery-energy-storage lifecycle. Its core competencies include UL 9540 system certification, UL 9540A thermal-runaway and large-scale fire testing, battery cell, module, and pack validation, as well as safety assessment, regulatory support, and follow-up compliance services. The company has strengthened its BESS capabilities by expanding specialized testing infrastructure, including its Advanced Battery Testing Laboratory in Aachen, Germany, and by collaborating with CATL under its Witness Test Data Program for battery and energy storage testing. Rather than integrating into battery manufacturing or BESS project ownership, UL Solutions follows a service-chain integration model that combines testing, certification, fire-risk assessment, technical documentation, market-access support, and post-certification surveillance. This positioning enables the company to serve battery suppliers, BESS OEMs, system integrators, developers, utilities, insurers, and approval authorities across product qualification, project approval, commissioning, and operational safety assurance.

Intertek Group plc follows a strategy of strengthening its position as an end-to-end assurance partner for battery and energy-storage stakeholders, with a focus on safety-critical testing, product certification, quality assurance, supply-chain traceability, and project-level technical support. Its core BESS competencies include UL 9540 system certification, UL 9540A thermal-runaway testing, battery safety and performance testing, environmental validation, grid compliance testing, and factory quality assurance services. A major strategic activity was the 2022 acquisition of Clean Energy Associates (CEA), a provider of quality assurance, supply chain traceability, and technical services for solar and energy storage projects; the business was subsequently integrated and rebranded as Intertek CEA in 2025. This represents horizontal and adjacent-service integration, extending Intertek’s laboratory testing and certification portfolio into upstream supplier quality, manufacturing surveillance, traceability, and project-development assurance. Rather than vertically integrating into battery manufacturing, BESS integration, or asset ownership, Intertek combines these independent assurance capabilities to support customers from product qualification through project delivery and operational readiness.

Markets Ranking

UL Solutions, Intertek Group plc, TÜV Rheinland, TÜV SÜD, and DNV constitute the key companies profiled in the BESS TIC market. UL Solutions differentiates through UL 9540 and UL 9540A certification and large-scale fire testing, while its Witnessed Test Data Program collaboration with CATL extends approved testing capacity into a major battery manufacturer’s laboratory. Intertek combines product testing and certification with upstream supplier quality, manufacturing surveillance, and traceability services through its acquisition and subsequent integration of Clean Energy Associates, now known as Intertek CEA. TÜV Rheinland provides a linked service pathway from document review and standards-based testing to factory inspection and certification, while its BESS traceability service addresses supply chain and battery data requirements. TÜV SÜD focuses on accredited ESS and stationary-battery testing, certification, and market-access support across international standards. DNV is differentiated by independent engineering, supplier due diligence, grid interconnection reviews, safety and permitting support, and operational performance assessment of storage assets. Two strategies dominate the competition: BESS-specific technical specialization, pursued most visibly by UL Solutions, Intertek, TÜV Rheinland, and TÜV SÜD, and lifecycle project assurance, in which DNV and Intertek extend beyond laboratory validation into procurement, financeability, commissioning, and asset operation support. Strategic collaborations reinforce these positions by connecting TIC providers with OEM laboratories, developers, and technology partners.
