储能行业跟踪报告：把握IRR测算：储能项目投资的核心抓手

Investment Rating - The report maintains a "Buy" rating for the energy storage sector [6] Core Insights - The investment in energy storage projects is returning to fundamental principles, focusing on capital IRR as a key metric for evaluating project value, with a threshold of 6.5% for good investment value [1][16] - The release of Document No. 114 has accelerated the alignment of profitability models for energy storage plants, shifting from a "strong allocation" to a market-driven economic model [14][15] Summary by Sections 1. Capital IRR Measurement - The capital IRR for energy storage projects is influenced by four core indicators: capacity price level, market arbitrage price difference, EPC costs, and lifespan of the storage station [2][17] - The basic scenario estimates a capital IRR of 5.5% under conservative assumptions, with potential increases based on variations in capacity pricing and market conditions [22][46] 2. Sensitivity Analysis - If the coal power capacity price is set at 330 CNY/kW·year, the capital IRR could reach 15.4% [23] - A 0.01 CNY/kWh increase in market arbitrage price can raise the project IRR by 1.4 percentage points, while a 0.1 increase in daily charge and discharge cycles can increase IRR by 4.4 percentage points [36][27] 3. Provincial Analysis - In 2025, provinces like Shanxi, Inner Mongolia, Shandong, and Gansu are projected to have capital IRR above 6.5% due to favorable market conditions [4][49] - The report emphasizes the need to monitor monthly changes in electricity market price differences and the pricing of coal power capacity in various provinces [4][49] 4. Investment Recommendations - The report suggests that the installed capacity of large-scale energy storage in 2026/2027 is a critical variable for lithium battery demand, with ongoing observation needed on capacity pricing, project lists, and market price changes [4][5] - The domestic energy storage industry is entering a healthy development phase, benefiting leading companies such as CATL, Sungrow, EVE Energy, and Haibo [4][5]
