For CAES, air severs as an energy storage medium and is compressed into the cavern by using the excess electrical energy. Then, when needed, the air is released to turbines for generating power ( Succar et al., 2008, Raju and Khaitan, 2012, Budt et al., 2016, Menéndez et al., 2022 ), as shown in Fig. 1 .
