Summary of Key Points Core Viewpoint - The article provides an analysis of the new energy storage market in China, focusing on the user-side market for August 2025, highlighting significant growth in installed capacity and the dominance of commercial applications in this sector [2][5]. Group 1: Overall Market Analysis - In August 2025, the total newly commissioned energy storage projects in China reached 2.90 GW and 7.97 GWh, representing a year-on-year increase of 30% and 43%, respectively, but a month-on-month decrease of 11% and 10% [2][4]. - The user-side energy storage market saw a significant increase in installed capacity, with 408.3 MW and 894.3 MWh added, marking a year-on-year growth of 124% and 137%, and a month-on-month increase of 66% and 73% [5][6]. Group 2: User-Side Market Characteristics - The user-side storage market is predominantly driven by commercial applications, accounting for over 90% of the new installations. The commercial sector added 376.63 MW and 828.85 MWh, with year-on-year growth of 115% and 131% [6][9]. - All newly commissioned projects utilized electrochemical storage technology, with lithium iron phosphate battery technology comprising 98.7% of the installed capacity. Additionally, two vanadium redox flow battery projects and one solid lead battery project were completed, with an average storage duration of 4.19 hours [6][9]. Group 3: Regional Distribution - The newly commissioned projects were primarily concentrated in Guangdong, Sichuan, Jiangsu, Anhui, and Zhejiang, with Guangdong accounting for 35% of the total installed capacity. Jiangsu had the highest number of projects, making up over 20% of the national total [9][10]. - In Guangdong, financial incentives were provided for new energy storage projects, including a maximum subsidy of 1 million yuan for virtual power plant connections [9][10]. Group 4: Price Differential and Market Dynamics - The price differential between peak and valley electricity rates exceeded 0.7 yuan/kWh in 21 provinces, with some areas in Guangdong surpassing 1 yuan/kWh. This creates a high potential for "price arbitrage" in user-side storage, making it a key area for investment [10][13]. - However, the current user-side storage projects primarily adopt a contract energy management model, which complicates profit-sharing with industrial users, leading to challenges in charging for electricity savings [10][13].
