What advantage does energy storage provide to the electrical grid?

Energy storage plays a significant role in enhancing the efficiency and reliability of the electrical grid, particularly by allowing for energy supply during peak demand. This advantage is crucial because energy consumption often fluctuates throughout the day, with demand typically higher during certain periods.

By storing energy when demand is low—such as overnight or during times when renewable sources like solar and wind are generating excess power—energy storage systems can release this stored energy back into the grid when demand surges. This helps to balance supply and demand, preventing outages and ensuring that there is enough energy available for consumers and businesses during peak usage times.

Furthermore, this capability reduces the need to activate additional power plants, which can be less efficient and more polluting, thereby supporting a cleaner and more sustainable energy profile for the grid.
