全球近五分之一储能项目“带病运行”

Group 1 - The report by Accure highlights that 19% of global energy storage projects suffer economic losses due to technical issues and unexpected shutdowns [1] - Common issues include automatic shutdowns to prevent equipment damage, recurring safety alarms, and imbalances at the battery group or module level [1] - Most energy storage projects over-specify system capacity by 15% to 25% to mitigate battery degradation, with smaller projects exceeding 30% to 35% [1][2] Group 2 - Only 83% of projects meet or exceed rated capacity during on-site acceptance testing, with lithium iron phosphate battery systems often showing a state of charge estimation error of ±15%, and some exceeding ±40% [1][2] - The report indicates that over one-third of sampled systems achieve over 88% round-trip efficiency, while some systems fall below 85% [2] - A 1% to 2% efficiency loss can translate into millions of dollars in revenue loss over the lifecycle of the project [2] Group 3 - The report is based on operational data from over 100 grid-scale energy storage systems, covering more than 18 GWh of operational battery storage assets from June 1 to September 1, 2025 [2] - The carbonates and electrolytes market faces supply-demand imbalances and increased competition due to rapid capacity growth and global trade adjustments [3] - The upcoming conference aims to address industry challenges and explore opportunities through technological and product innovations [3][4]
