Pumped storage is a smart way to save electricity for later when it's needed most. According to a 2021 research study, the energy cycle between the two reservoirs has a whopping 90% efficiency level – meaning that it only loses 10% of the surplus energy that passes through its turbine.
Following are some of the many advantages associated with the use of pumped storage hydropower generation, instead of relying on the more conventional, thermal, and nuclear sources. Once constructed, pumped hydropower plants have a long life and minimal maintenance requirement.
This means such projects are not feasible on smaller scales. The biggest drawback for the overall efficiency of pumped storages is the fact that the water needs to be 'pumped' from the lower reservoir to the upper reservoir for the cycle to be completed. And this part of the cycle consumes electrical energy itself!
