In terms of electricity consumption, energy storage enables the process of storing energy when it is not needed and releasing it when demand arises. This technology is transforming the traditional model of power systems—where electricity generation, transmission, and consumption must occur simultaneously. Acting like a large-scale "power bank," energy storage systems can function as a load during off-peak hours by charging up, and then serve as a power source during peak periods by discharging electricity back into the grid.

Regarding power quality, energy storage offers fast, stable, and precise charge-discharge regulation. It can provide a wide range of grid services including peak shaving, frequency regulation, backup power, and demand response. As such, it plays a crucial role in building resilient and flexible power systems, enabling a more harmonious and interactive relationship between the grid and storage assets—paving the way for smarter, more adaptive energy infrastructures.
