Analogy

Imagine a water tank that collects rainwater. During periods of heavy rainfall, the tank fills up, storing excess water. When there is a drought or a shortage of water, the stored water can be used to meet the demand. Similarly, energy storage systems store excess energy during periods of low demand and release it during high demand, optimizing energy usage and improving overall efficiency.
