Grid storage refers to systems that store energy for later use, helping to balance supply and demand in electrical grids. These systems can store excess energy generated from renewable sources like solar panels and wind turbines when production exceeds consumption. This stored energy can then be released during peak demand times, ensuring a stable and reliable power supply. Common types of grid storage include batteries, pumped hydro storage, and compressed air energy storage. Each technology has its own advantages and applications, but all aim to enhance the efficiency and resilience of the energy grid, supporting the transition to cleaner energy sources.
