An Energy Storage System (ESS) refers to technologies designed to store energy—especially from renewable sources like solar and wind for later use. ESS plays a crucial role in balancing supply and demand, improving grid stability, and enhancing energy reliability. Common storage technologies include hydro (such as pumped hydro storage), batteries (like lithium-ion), thermal storage, and flywheels. These systems help maximize the efficiency and utility of intermittent renewable energy.
