3 6 Ke·2025-08-11 03:39Core Viewpoint - Hunan Province, a leading region in energy storage capacity, is facing significant financial losses in its energy storage projects, raising concerns about the sustainability and profitability of the energy storage industry in China [1][2]. Group 1: Financial Performance - In June, Hunan's independent energy storage stations reported a total charging and discharging revenue of -21.27 million yuan, indicating widespread financial losses across 31 energy storage stations [1][3]. - The average charging price was approximately 0.66 yuan/kWh, while the average discharging price was only 0.45 yuan/kWh, leading to a negative price differential [7][8]. - Companies like Xue Tian Salt Industry and Hua Zi Technology have reported significant losses, with Xue Tian terminating a major energy storage project due to poor revenue expectations [5][6]. Group 2: Market Conditions - The energy storage market in Hunan is characterized by oversupply and intense competition, with low rental prices for capacity leading to reduced revenues for energy storage projects [8][9]. - The weighted average rental price for capacity in Hunan dropped from 126 yuan/kWh·year in the first half of 2023 to 60 yuan/kWh·year in 2024, reflecting a significant decline in market value [9][14]. - The rapid increase in energy storage installations has resulted in a supply surplus, with Hunan's new energy storage capacity reaching 273.3 MW by September 2024 [9]. Group 3: Industry Implications - The widespread losses in Hunan's energy storage sector serve as a warning for the national energy storage industry, highlighting the risks of over-investment and the need for regulatory intervention [11][12]. - Other provinces, such as Guangdong, are beginning to implement restrictions on new energy storage projects to prevent oversaturation in the market [12][13]. - The decline in capacity rental prices across various regions indicates a broader trend that could threaten the profitability of energy storage investments nationwide [14].
