The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s.Hydro power is not only a renewable and sustainable energy source, but its flexibility and storage capacity also make it possible to improve grid
In addition, the benefits of using storage devices for achieving high renewable energy (RE) contribution to the total energy supply are also paramount. The present study provides a detailed review on the utilization of pump-hydro storage (PHS) related to the RE-based stand-alone and grid-connected HESs.
RE installed capacity without hydro power energy (1,081 GW) is almost half of the RE capacity with hydro (2,195 GW), indicating that hydro energy has more than 50% share in RE. Moreover, continuous increase in deployment of solar, wind and hydro can be seen from 2010 and onwards, which shows the technical and economic viability

We can distinguish three types of hydroelectric power stations capable of producing energy storage: the power stations of the so-called "lake" hydroelectric schemes, the power stations of the "run-of-river" hydroelectric schemes, and the pumping-turbine hydroelectric schemes (Read: Hydraulic works ).
Pumped storage hydropower stands as a robust and reliable source of renewable energy, primarily due to its unique method of energy storage and generation. Unlike wind power or solar, which depend on the weather, pumped storage gives
Australia already has river-based pumped hydro energy storage facilities at Wivenhoe, Shoalhaven and Tumut 3. Construction of Snowy 2.0 has commenced—this project would add 2,000 MW of generation to the National Electricity Market (NEM) and provide about 175 hours of storage.

Pumped hydro storage systems are responsible for supplying 95% of the global electrical energy storage power capacity (GW) and 90% of the world''s energy storage (GWh) []. However, despite these advantages, various researchers turn a blind eye to pumped hydro and presume that pumped hydro lacks future development [ 21 ].
There has been a renewed commercial and technical interest in pumped hydro energy storage (PHES) recently with the advent of increased variable renewable energy generation and the development of liberalized electricity markets. During the next 8 years over 7 GW of PHES capacity will be added to the European network while projects

The fundamental principle of pumped hydroelectric storage is to store electric energy in the form of hydraulic potential energy. Pumping typically takes place
The idea to hybridize a PSHP with more than one energy storage device is interesting as the few hybrid power plants with hydro generation and energy storage are equipped with BESS. BESSs have been integrated in a few existing hydro plants so as to improve the plant''s performance in the frequency control ancillary services while
Combining wind energy with pumped hydro energy storage (PHES) can overcome this intermittency, consuming energy during low-demand periods and supplying energy for periods of high demand. Currently Ireland has a number of hydroelectric power plants and wind farms of various scales in operation.
Globally, communities are converting to renewable energy because of the negative effects of fossil fuels. In 2020, renewable energy sources provided about 29% of the world''s primary energy.
