Core Insights - The report highlights the contradiction faced during the "14th Five-Year Plan" period, where carbon reduction pressures are increasing while the growth rate of new energy installations is slowing down. The introduction of a national capacity price policy is expected to open up space for new energy installations and support high-yield investment options for power companies during the "14th Five-Year Plan" investment intensity [5][6][9]. Group 1: Energy Storage Industry - The national capacity price policy, issued on January 30, 2026, aims to establish a mechanism that balances power supply stability, green energy transformation, and efficient resource allocation. This policy is expected to support the development of adjustable power sources and enhance the installation of new energy [7][9]. - The report estimates that the demand for energy storage will show a high growth trend, with new energy storage installations expected to reach 66.43 GW and 189.48 GWh in 2025, representing year-on-year increases of 52% and 73% respectively [8][9]. - The capacity price policy is seen as the final piece needed for energy storage development, potentially increasing project returns from approximately 6.5% to over 8% under current subsidy conditions. This is expected to stimulate investment interest from state-owned enterprises in new energy storage projects [8][9]. Group 2: Investment Recommendations - The report suggests prioritizing investments in leading companies involved in energy storage integration and upstream battery cells, recommending firms such as Sungrow Power Supply, Trina Solar, LONGi Green Energy, JinkoSolar, CATL, and Eve Energy. It also advises monitoring companies like Haisum, Sungrow Electric, Canadian Solar, and Penghui Energy [9].
