Energy Storage | Understand Energy Learning Hub
Energy storage is a valuable tool for balancing the grid and integrating more renewable energy. When energy demand is low and production of renewables is high, the excess energy can be stored for later use. When demand for energy or power is high and supply is low, the stored energy can be discharged. Due to the hourly, seasonal, and locational
