Battery storage

Definition

Battery storage refers to the use of batteries to store electrical energy for later use, providing a reliable means to manage energy supply and demand. This technology plays a crucial role in power smoothing and storage techniques by storing excess energy generated during peak production times and releasing it during periods of high demand, thereby enhancing grid stability and efficiency.
