Pumped Storage Hydropower: Benefits for Grid Reliability and Integration of Variable Renewable Energy Decision and Information Sciences Division About Argonne National Laboratory
Forms of PSH that are seawater-based, small-scale or based at former mining sites could potentially mitigate some of these impacts and enable PSH development in areas where it is not currently practical. Pumped storage hydropower stores energy and provides services for the electrical grid.
Nature Reviews Clean Technology (2025) Cite this article Grid-scale energy storage is increasingly important as variable renewable energy is integrated into power systems. Pumped storage hydropower (PSH) provides the largest form of energy storage in power grids, with 179 GW installed globally as of 2023.
A coordinated optimization framework for flexible operation of pumped storage hydropower system: nonlinear modeling, strategy optimization and decision making. Energy Convers. Manag. 194, 75–93 (2019).
These hybrid systems are primarily classified into three categories: PSH–conventional hydropower systems; PSH–VRE systems; and PSH–fast-acting energy-storage systems. PSH–conventional hydropower systems couple PSH and hydropower plants to improve the integration and management of VRE and the performance of pump–turbines (see the figure in Box 1).
Hybrid systems that combine PSH with hydropower or battery storage are also being developed. PSH can balance electrical demand through dispatch, frequency and voltage regulation, and other ancillary services essential to the system, with different timescales for each service.
PSH plants provide voltage control to the grid by controlling reactive power in the same way as conventional hydropower plants, as they are usually equipped with synchronous generators and automatic voltage regulators 172. PSH can provide voltage control in generation, consumption or synchronous condenser mode.
