首次下降！一季度新型储能项目新增装机5.03GW/11.79GWh

Core Viewpoint - The article discusses the performance and trends of new energy storage projects in China during the first quarter of 2025, highlighting a slight decline in installed capacity compared to the previous year, while emphasizing the growth in independent storage projects and advancements in storage technology [1][3][4]. Summary by Sections New Installed Capacity - In Q1 2025, China added 5.03 GW/11.79 GWh of new energy storage capacity, representing a year-on-year decrease of 1.5% and 5.5% respectively [1]. - The grid-side contributed 4.46 GW/10.57 GWh, with a minor decline of 0.2% and 4.4% year-on-year, while the user-side added 575 MW/1124 MWh, showing a more significant drop of 10.9% and 11.6% [1]. Regional Distribution - New energy storage projects were launched across 24 provinces, with Hebei leading in scale. Notably, several independent storage projects exceeding 100 MW were commissioned in Hebei, contributing to a total installed capacity of over 1 million kW [3][4]. Application Distribution - Independent storage projects accounted for over 50% of the new installed capacity, with grid-side power capacity making up 52%, an increase of 17 percentage points year-on-year. The grid-side added 2.63 GW/6.48 GWh, reflecting a year-on-year growth of 46% and 68% respectively [4]. - The power generation side saw a decrease in installed capacity of 31% year-on-year, while the user-side also experienced an 11% decline, primarily in commercial and industrial storage applications [4]. Technology Trends - The majority of new projects utilized electrochemical storage technology, with lithium battery projects comprising 98% of the total. Phosphate lithium battery technology remains dominant [7]. - Several mixed storage projects were launched, combining various technologies such as lithium-ion and sodium-ion batteries, as well as supercapacitors [7][12]. Notable Projects - Key projects include the largest grid-side independent storage project in China located in Hebei, with a capacity of 300 MW/1200 MWh, and the first mixed network-type storage project, which integrates multiple storage technologies [11][12].
