One major problem with wind and solar energy is that they are conditional. Explain how hydroelectric pumped storage could be used to eliminate this obstacle?

These pumps allow the energy to be saved for later use, whenever the load increases.

Explanation:

These hydroelectric pumps are a vast connection of ancillary grid services. These act as storage plants. These enable an electric provider to balance energy and provide stability. This network not only has reservoirs but also controls the frequency of the energy produced.  

Due to this, within a few seconds, large amounts of electricity can be produced.

Hydroelectric Pump is a set of two water reserves which pump water through turbines to generate energy at various required elevations. The produced energy is stored by various electric power systems.
