BESS testing market to double to $1.30b by 2032 on rising safety needs

APAC, which accounted for 40% of global revenue, is expected to remain the largest market.

The global market for battery energy storage system (BESS) testing, inspection, and certification services is projected to grow to $1.30b by 2032 from $660m in 2026, according to MarketsandMarkets.

Market growth is attributed to increasing requirements for system safety, thermal runaway prevention, fire risk assessment, grid code compliance, and commissioning validation.

Asia-Pacific is expected to remain the largest regional market, accounting for about 40% of global revenue in 2026, whilst Europe is projected to record the fastest growth through 2032.

Demand is extending beyond initial product qualification to certification, technical due diligence, battery traceability, documentation support and lifecycle assurance as the market is projected to expand at a compound annual growth rate (CAGR) of 11.8% between 2026 and 2032.

Testing id poised to emerge as the largest service segment, accounting for about 50% of the market in 2026, whilst certification is forecast to record the fastest growth through 2032.

The report said testing generates the largest share because it is required throughout the product and project lifecycle, including battery cell and module qualification, system integration, factory acceptance, site acceptance, commissioning, and operational performance verification.

Design changes to battery cells, racks, power conversion systems, battery management systems, energy management systems, and fire suppression systems also require renewed validation.

Outsourced TIC services are expected to account for about 65% of the market in 2026 before rising to 72% by 2032. Project developers are projected to be the fastest-growing end-user group, with a CAGR of about 17%.
