When renewable power production exceeds demand, batteries store excess electricity for later use, therefore allowing power grids to accommodate higher shares of renewable energy and supply electricity regardless the time and weather. Today lithium-ion batteries are a cornerstone of modern economies having revolutionised electronic devices and electric mobility, and are gaining traction in power systems. Yet, new battery. . Battery energy storage system (BESS) can address these supply-demand gaps by providing flexibility to balance supply and demand in real-time. But it is a different story at night.
