During the implementation of EPC projects for independent electrochemical energy storage power stations

unique characteristics and quality issues have emerged.From the perspective of engineering management

this paper focuses on the prevalent quality issues in foundation embedded components

cable trenches

fire protection systems

and equipment.By examining the design

construction

procurement

and commissioning stages in the EPC construction process

it systematically analyzes the causes of common quality defects and puts forward targeted preventive and control measures accordingly.
