2026-01-26 02:50Summary of ESS Battery Industry Conference Call Industry Overview - Global ESS Battery Demand: The demand for Energy Storage Systems (ESS) batteries is projected to accelerate significantly, with shipments expected to reach approximately 640 GWh in FY25, reflecting a year-over-year growth of over 90% [2][5][37]. - China's Role: China's domestic demand is a primary growth driver, with shipments surging over 100% year-over-year in 4Q25 due to supportive policies [2][11]. The country accounts for about 97% of global ESS battery supply [41]. Key Insights - December Shipment Performance: December 2025 shipments were robust at 85 GWh, marking a 34% month-over-month increase and a 90% year-over-year increase [2][21]. - Future Projections: The base case model anticipates global ESS battery shipments to grow over 40% to around 900 GWh in 2026, driven by policy support from China and strong order momentum from Europe [3][37]. - Policy Changes: China's Ministry of Finance announced a reduction in VAT export rebates from 9% to 6% starting April 2026, which is expected to optimize capacity structure and reduce market involution, benefiting leading players like CATL [2]. Company Highlights - CATL: As the largest ESS battery maker globally, CATL is well-positioned to gain market share with new capacity releases. It is projected that ESS will account for 20% of CATL's total battery production volume in FY26 [12][14][109]. - Sungrow: Recognized as the largest solar inverter producer, Sungrow is expected to benefit from rising ESS demand, particularly in emerging markets [4][12]. - LGES: LG Energy Solution is well-positioned to capture growth in the US ESS market, having commenced production of LFP ESS batteries in Michigan [12][14]. - BYD: ESS accounts for 17% of BYD's total battery production volume in FY25, indicating a growing focus on this segment [106]. Market Dynamics - Export Trends: Chinese ESS battery exports to the US saw a significant increase of 126% year-over-year in FY25, driven by rush purchases ahead of tariff hikes [48]. However, shipments to the US slowed to 9% year-over-year in 4Q25 due to tariff shifts [13]. - Price Trends: ESS battery prices from Chinese manufacturers increased by 1-2% in 4Q25, following a rebound of 5-10% earlier in the year [13][100]. Competitive Landscape - Market Share: CATL's global market share fell by 10 percentage points in FY25 due to capacity constraints, while competitors like Hithium and BYD gained market share [72][99]. CATL holds nearly 50% of the US market share and about 20% in the EU [50]. - Emerging Competitors: Companies like Gotion and Narada are gaining traction in the telecom ESS market, with Gotion achieving a 5 percentage point market share increase [99]. Conclusion The ESS battery market is poised for substantial growth, driven by strong demand in both domestic and international markets, particularly in China and the US. Leading companies like CATL, Sungrow, and LGES are well-positioned to capitalize on these trends, although they face increasing competition and market dynamics that could impact their market shares.
