Regional Analysis Asia-Pacific remains the largest region, leading the global market in 2025 with a 33% share. This growth is supported by manufacturing output and cumulative deployments, anchored by China’s dominant cell production and large domestic procurements. Many major cell makers (CATL, BYD) and pack integrators are in Asia, supplying global projects and creating regional cost advantages. Government industrial policy in China, Japan and South Korea supports local gigafactories, and large renewable buildouts across APAC create steady demand for co-located storage to reduce curtailment and firm output. The region also includes rapidly growing markets (Australia, India) with high procurement ambitions for storage to support grid stability and renewables integration. China leads global cumulative energy-storage manufacturing and installations, driven by domestic cell giants, provincial procurement and large renewables buildouts. The National Energy Administration’s 2024/2025 reporting shows massive additions and regional rollouts; local governments and large state developers continue to procure storage to cut curtailment and firm variable generation. China’s integrated supply chain and aggressive plant buildouts give it a scale advantage and cost leadership in 2025. India’s BESS market expanded rapidly in early 2025 as utilities and central agencies issued large standalone storage tenders to stabilise the grid and integrate rising solar capacity. NTPC, SECI, and other agencies have released multi-GW tenders and pilot programs, including viability-gap funded bids, and recent tenders have delivered record-low tariff results, indicating improved procurement economics. India’s policy focus includes using storage to reduce curtailment, enable coal-plant flexibility and support new renewables targets. State utilities and central ownership models (NTPC) are actively testing BESS at thermal plants for hybrid flexibility.
