The storage was not part of the traditional electricity network in the past, but it is a game changer especially with the advancement of technology. Three main scenarios have been developed to achieve energy savings, reduce CO2 emissions and increase demand-side energy storage of 110 GWh by 2030, according to Jordan's Energy Strategy 2020. -2030. Another scenario was worked out to reduce energy from the generation side and energy storage by replacing 110 GWh of diesel generators on the generation side, and the result was a saving of 178 million dinars annually and 110 GWh from the generation side. The final scenario was created to achieve load conversion from excess energy at peak sun hour and send it at night at peak demand. in Jordan by generating 311 GWh at Mujib Dam by 2030, the project is not economical but important for the purpose of providing grid services.

INTRODUCTION Pumped Hydro storage (PHS) works on the premise of storing electrical energy by exploiting the potential energy of water. Water will be pumped and stored in an above tank/pool during periods of low demand and high availability of electric power. The energy can be released and turned into electrical energy in a short amount of time during peak load As a result, the PHS system can gradually modify demand supply to achieve equilibrium, reducing the gap between peak and off- peak periods, and playing an essential role in the settlement of other power plants and the power grid's stability. With a round-trip efficiency of 65-70 percent, these PHS are reasonably efficient. The quantity of energy stored is determined by the volume of water pushed and the distance between reservoirs [1]. The majority of PHS stations in the United States were built between 1960 and 1990. Significant gains in nuclear capacity occurred during this time period. Note that in the 1970s, considerable rises in the cost of crude oil and gas, combined with uncertainty about future pricing, led utilities in the United States to consider PHES as a viable alternative to fossil fuel peaking units. PHES stations were typically more economically appealing than conventional peaking stations in recent years, because to lower electricity price ranges for PHES units. As a result of subsequent drops in the price of oil and gas, as well as huge decreases in the capital costs of Combined Cycle peaking units, there has been minimal deployment of PHES in the United States since 1990. According to some articles, the United States has a PHS potential of more than 1000 GW [2]. The 770 MW Nagarjuna agar plant, which was fully operational in 1981, was India's first pumped storage project. Another 742 MW of PHES was added between 1981 and 1998, followed by another 3450 MW between 2003 and 2008. The desire to fulfill peak electrical demand is the primary reason for installing PHES in India; most states' peak power capacity falls short of peak demand by 10-15% [2]. II. WHY PHS IS IMPORTANT? PHS systems will let utilities to balance the grid more efficiently and expand their renewable energy portfolios. Large-scale storage options and grid operations are aided by their flexibility. In reality, the addition of intermittent renewable generation has increased the level of uncertainty in the interconnected power system's dispatch. Pumped storage will thus play a critical role in allowing renewables' grid integration while also assisting governments in meeting their ambitious targets for reducing GHG emissions and expanding sustainable renewable energy generation [3]. The use of energy is steadily growing. Simultaneously, maintaining a constant balance between energy production and consumption is getting more difficult. Pumped storage facilities, as multifunctional power plants, have a strong chance of meeting this challenge since their technology is based on the only long-term, technically established, and cost- effective method of storing energy on a large scale and making it accessible at short notice [3]. Pumped storage is a dispatchable energy source since it can be used anytime demand arises. When intermittent, non- dispatchable sources such as wind and solar electricity are unable to satisfy demand, it is frequently used [4].
