Summary of China Energy Storage Industry Conference Call Industry Overview - The focus is on the **Battery Energy Storage System (BESS)** industry in China, which is expected to benefit from policy tailwinds and cost reductions, enhancing its economic viability [2][5][34]. Key Points and Arguments Policy Tailwinds - China's BESS projects are anticipated to gain from diversified revenue streams, larger peak-trough pricing spreads, and capacity pricing mechanisms [2][3]. - The cancellation of mandatory renewables attachment allows standalone BESS to capture market share, leading to a more diversified revenue model [3][8]. Economic Viability and Returns - If the peak-trough pricing spread increases from Rmb0.25/kWh to Rmb0.4/kWh, the Internal Rate of Return (IRR) for BESS projects could rise from 2.5% to approximately 8% [3][11]. - With additional capacity compensation, the IRR could potentially reach around 13% [3][11]. Cost Reductions and Grid Parity - The cost of BESS projects has decreased by 67% since 2022, with theoretical levelized cost of storage (LCOS) at Rmb0.12/kWh [23]. - The actual LCOS is higher due to low utilization rates, estimated at Rmb0.4-0.5/kWh [24]. - Improvements in utilization and cycle life are expected to drive down costs further, making BESS projects more economically viable [25]. Installation Forecasts - BESS installation forecasts for China have been raised by 7-19% to 150GWh/232GWh for 2025/26E, with a projected CAGR of 27% from 2027-2030, reaching 666GWh by 2030 [5][33]. - Global BESS installations are also expected to rise, reaching 276GWh/412GWh in 2025/26E and 1,045GWh by 2030 [5][33]. Market Dynamics - Installed capacity in China surpassed 100GW by the end of Q3 2025, accounting for over 40% of global capacity [7]. - BESS installations grew by 65% YoY to 34GW in 9M25, but low utilization rates (32% in 2024) have led to weak profitability [7][8]. - Recent policy adjustments are improving utilization rates, with Document 136 requiring new renewable projects to sell through market transactions [8]. Revenue Models - Standalone BESS projects are expected to benefit from diversified revenue streams, including ancillary services, capacity leasing, and spot market arbitrage [3][14]. - Capacity compensation mechanisms have been introduced in various provinces, enhancing revenue potential for BESS projects [15][16]. Challenges and Risks - Key risks include slower-than-expected growth in domestic renewable energy capacity, smaller peak-trough price spreads, and potential import restrictions on Chinese products [40]. - The current low margins for BESS manufacturers in China are expected to recover in the long term due to rising demand and improving IRRs [34]. Conclusion - The BESS industry in China is poised for significant growth driven by favorable policies, cost reductions, and evolving market dynamics. Key players like **Sungrow** and **CSI Solar** are expected to benefit from this trend, despite current challenges in profitability and market conditions [5][34].
