This paper investigates the thermodynamic performance of a compressed air energy storage (CAES) system integrated with a coal-fired power plant. The proposed configuration stores excess electricity by compressing air and later releases the stored energy to support electricity generation through the plant’s steam cycle. The study develops a thermodynamic model to analyse system performance and evaluates how the integrated CAES system affects efficiency and operational flexibility. Results show that coupling compressed air energy storage with coal-fired power plants can improve load regulation capability and enhance grid flexibility, while enabling existing power plant infrastructure to support large-scale energy storage for renewable energy integration.
