For both batteries and pumped hydro, some electricity is lost when charging and discharging the stored energy. The round-trip efficiency of both technologies is usually around 75% to 80%. This level of efficiency for either technology represents a significant displacement of non-renewable generation if we assume.

Batteries have a slightly higher efficiency, but pumped hydro energy storage is still a highly efficient technology. Currently, the cost of pumped hydro energy storage is around $150 per kWh, while the cost of battery storage ranges from $300 to $500 per kWh.
For each type of activity, it is readily apparent that these NPC and COE values are lesser than those of PV/HES and Wind/HES systems. For this reason, among the systems that make use of pumped hydro energy storage, the PV/Wind/HES system appears to be the most appropriate option.
Despite all these drawbacks, pumped storages are more than 80 percent energy efficient in a complete cycle. And can provide almost double the electricity compared to lithium-ion batteries. The fish population can be threatened due to hindrance in their migration patterns.
The levelized cost of energy revealed that the ideal power capacity ratio was 1:5, and the pumped-hydro energy storage unit contributed 15 % of the total yearly load energy. Ali, et al. suggested putting in place an offline hybrid system with pumped-hydro energy storage that is reliable and robust.
Rapid Response: Unlike traditional power plants, pumped storage can quickly meet sudden energy demands. Its ability to reach full capacity within minutes is essential for maintaining electricity stability and balancing grid fluctuations. Sustainability: At its core, pumped storage hydropower is a sustainable energy solution.
