According to Table 5, it was observed that the average daily electrical energy consumed to charge the water tower based energy storage system is equal to 3.78 (MWh). The amount of electrical energy generated in the discharge stage is calculated using Eq. (53) as 2.415 (MWh).

In order to design the water tower required for energy storage, in the first case, the height of the tower tank is considered to be 5 (m). As a result, according to Eq. (50), the height of the tower will be 30 (m). Considering the radius of the tank equal to 4 (m), the cross-sectional area of the tank is about 50 (m 2).
Also, the energy used to pump water to the tower is equal to 26,229 (kWh). Therefore, the energy conversion efficiency of the water tower is equal to 70.94 %, and the efficiency of the entire energy recovery and storage system, which consists entirely of small towers, is 64.04 %. The required number of small water towers is calculated as 144.
