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.

Pumped hydropower storage systems are natural partners of wind and solar power, using excess power to pump water uphill into storage basins and releasing it at times of low renewables output or
Though pumped hydro has a longer operational lifespan and a lower cost per kilowatt-hour, battery storage is more suitable for widespread application due to its faster construction time (less than six months) compared to pumped hydro (4-5 years), and the fact it doesn''t need specific topography or water availability.
Batteries are more cost-effective at delivering small amounts of stored energy over a short time at high power levels. Pumped storage is more cost-effective at storing and releasing larger amounts of stored energy. Achieving the optimum storage solution will depend on careful planning and finding the best fit for the particular circumstances.

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine.

A major advantage of pumped hydro over batteries is that the expected life of pumped hydro is more than 100 years, or effectively unlimited with appropriate maintenance. Batteries may have a lower upfront cost than pumped hydro and be easier to approve and install; however, they are likely to require greater management over time.
Nevertheless, pumped hydro technology is mature, dam risks are generally well understood and managed, and the frequency of dam safety events is low. The main safety concern for batteries is thermal runaway leading to explosions and fires. The severity of this risk will depend on how a battery project is implemented.
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.
They’re adept at managing the rise of solar power midday when the sun is overhead and releasing it when power demand peaks in the evenings. Pumped hydro, on the other hand, allows for larger and longer storage than batteries, and that is essential in a wind- and solar-dominated electricity system.
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.
