Energy storage systems

Definition

Energy storage systems are technologies that capture and store energy for use at a later time, allowing for better management of energy supply and demand. These systems are particularly crucial for integrating renewable energy sources, like solar and wind, which can be intermittent in nature. By storing excess energy generated during peak production times, energy storage systems help ensure a steady and reliable supply of power, enhancing grid stability and efficiency.
