Introduction
This metric represents the ratio of the electrical energy output during generation (discharging) compared to the electrical energy input required to pump the water to the upper reservoir (charging). It can offer a wide range of services to the modern-day power grid, especially assisting the large-scale integration of variable energy resources. This report on accelerating the future of pumped storage hydropower (PSH) is released as part of the Storage Innovations (SI) 2030 strategic initiative.
