Hence, to suppress such fluctuations, energy storage is essential. Pumped hydro storage (PHS) in this context is one of the most attractive choices due to high efficiency, reliability and low cost. This paper discusses the use of PHS for removing the intermittency in supplies from solar and wind energy.
Pumped hydro storage uses two water reservoirs which are separated vertically. In times of excess electricity, often off peak hours, water is pumped from the lower reservoir to the upper reservoir. When required, the water flow is reversed and guided through turbines to generate electricity. | Tue, 11/08/2016.
Congestion in power flow, voltage fluctuation occurs if electricity production and consumption are not balanced. Application of some electrical energy storage (EES) devices can control this problem. Pumped hydroelectricity storage (PHS), electro-chemical batteries, compressed air energy storage, flywheel, etc. are such EES. Considering the

PSPP Castaic Los Angeles County, California, USA. Today more than 150 GW of pumped storage capacity is installed throughout the world. In 2016 about 6.4 GW – nearly twice the amount installed in 2015 – was added worldwide. A further 20 GW of pumped storage capacity is currently under construction across the globe.
Pumped hydro energy storage is by far the largest, lowest cost, and most technically mature electrical storage technology. Closed-loop pumped hydro storage located away from rivers ("off-river")
Pumped storage plants store energy using a system of two interconnected reservoirs with one at a higher elevation than the other. Water is pumped to the upper reservoir in times of surplus energy and, in times of excess demand, water from the upper reservoir is released, generating electricity as the water passes through reversible Francis turbines on its way
5.5 Pumped hydro energy storage system. Pumped hydro energy storage system (PHES) is the only commercially proven large scale ( > 100 MW) energy storage technology [163]. The fundamental principle of PHES is to store electric energy in the form of hydraulic potential energy. Pumping of water to upper reservoir takes place during off-peak hours
The Ludington Pumped Storage Plant began operating in 1973, making it essentially a battery that still works after 50 years.

Out of all the current technologies, pumped storage is the most extensively used method for storing energy on a large-scale and for an electric grid''s power modulation. 26 It is the most appealing option as it can hold a large amount of potential energy in the reservoirs. 27 Pumped-storage hydroelectricity (PSH) balances the load
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 (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized
Typically, PHES comprises one upper and one lower reservoir (closed-loop system) or one upper reservoir and a river, sea lake or other body of water as a lower reservoir (open-loop system). It assists with energy time-shifting and is characterised by a long lifespan (50–100 years) ( Guittet et al., 2016 ), high trip efficiency (70–87%) (
