What are Grid-Scale Batteries?
Grid-scale batteries, also known as utility-scale batteries, are large energy storage systems designed to supply power to the electrical grid. These batteries are typically mounted on the ground or integrated into existing infrastructure, such as power plants or substations. They can store excess energy generated by renewable sources, like solar or wind power, and release it when demand is high, helping to stabilize the grid and prevent power outages.
