Energy storage is essential for balancing the fluctuations in supply and demand within the energy sector. Among the many energy storage solutions, the pumped-storage hydropower (PSH) system stands out due to its high efficiency and large-scale capacity. The PSH system works by pumping water to a higher elevation during low-demand periods and releasing it during high-demand periods to produce electricity through turbines. This process allows for a more stable grid operation and reduces the need for fossil fuel-based backup generators, thus contributing to a greener energy infrastructure.
