“…Unfortunately, very little has been found about such a complex system as that which was the subject of this study. In the works dedicated to similar systems, the goal was not the analysis of the collapse but the possible installation and operation of such facilities [40][41][42]51]. Meanwhile, many studies are devoted to single dam failures or even more complex failures in cascaded reservoirs.…”

“…Such a rare layout of facilities is the object of the present study. The options of converting a hydropower plant into a pumped-storage hydropower plant or constructing an additional (upper) reservoir to balance the energy generation are being discussed in other countries as well [39][40][41][42]. Still, the present investigation was conducted as a case study of the existing hydropower system, which consists of two power plants (Kaunas hydropower plant (HP) and Kruonis pumped-storage hydropower plant (PSHP)) and upper and lower reservoirs.…”

Future global sustainability depends heavily on the development of renewable energy. The object of this study is a system of two plants (Kaunas hydropower plant (HP) and Kruonis pumped-storage hydropower plant) and upper and lower reservoirs. A possible dam failure accident in such an important system can endanger the population of Kaunas City. The methodology for estimating dam-failure-induced flood wave uncertainty included scenarios of the upper reservoir embankment failure hydrographs, modeling flood wave spreading (MIKE 21 hydrodynamic model), and estimating wave heights. The GRS methodology was selected to assess the uncertainty of flood wave modeling results and the sensitivity of hydrodynamic model parameters. The findings revealed that the discharge values of the Nemunas inflow and outflow through the HP outlets are the most important parameters determining the greatest height of the flood wave. Therefore, by correctly managing the amount of water in the upper reservoir, it would be possible to prevent the lower reservoir dam from breaking.

“…An open-loop PSH system could consist of a barrage in a river (creating the lower reservoir), with the upper reservoir being a small dam built on a nearby hill [45]. In some cases, existing conventional hydropower systems have been reconfigured as PSH systems, such as with the existing conventional hydropower dam forming the barrage in the river [47]. This is similar in nature to developing PSH in a brownfield site, as most of the negative environmental and social impacts associated with this type of PSH development have already occurred.…”

Because generating electricity significantly contributes to global greenhouse gas emissions, meeting the 2015 Paris Agreement and 2021 Glasgow Climate Pact requires rapidly transitioning to zero or low-emissions electricity grids. Though the installation of renewables-based generators—predominantly wind and solar-based systems—is accelerating worldwide, electrical energy storage systems, such as pumped storage hydropower, are needed to balance their weather-dependent output. The authors of this paper are the first to examine the status and potential for pumped storage hydropower development in 24 Pacific Rim economies (the 21 member economies of the Asia Pacific Economic Cooperation plus Cambodia, Lao PDR, and Myanmar). We show that there is 195 times the pumped storage hydropower potential in the 24 target economies as would be required to support 100% renewables-based electricity grids. Further to the electrical energy storage potential, we show that pumped storage hydropower is a low-cost, low-greenhouse-gas-emitting electrical energy storage technology that can be sited and designed to have minimal negative (or in some cases positive) social impacts (e.g., requirements for re-settlement as well as impacts on farming and livelihood practices) and environmental impacts (e.g., impacts on water quality and biodiversity). Because of the high potential for pumped storage hydropower-based electrical energy storage, only sites with low negative (or positive) social and environmental impacts such as brownfield sites and closed-loop PSH developments (where water is moved back and forth between two reservoirs, thus minimally disturbing natural hydrology) need be developed to support the transition to zero or low-carbon electricity grids. In this way, the advantages of well-designed and -sited pumped storage hydropower can effectively address ongoing conflict around the social and environmental impacts of conventional hydropower developments. Noting the International Hydropower Association advocacy for pumped storage hydropower, we make recommendations for how pumped storage hydropower can sustainably reduce electricity-sector greenhouse gas emissions, including through market reforms to encourage investment and the application of standards to avoid and mitigate environmental and social impacts.

“…"Simplified Model for Evaluation of Hydropower Plant Conversion into Pumped Storage Hydropower Plant" by S. Kiene and O. Linkevics [8] states that pumped storage hydropower plants currently represent the most mature and widespread storage technology, yet the construction of new facilities is often hampered by the limited choice of suitable sites. An interesting solution is to convert an existing hydropower plant into a pumped storage hydropower plant by building an additional pumping station that pumps water from the lower reservoir during low electricity prices, thus providing additional water for the hydropower units to generate electricity during peak loads.…”

The importance of the climate change problem is recognised by the governments of the overwhelming majority of the world’s countries. To bring additional attention and enable more concrete action, in a number of countries and municipalities the issue has been declared a climate emergency. The need to solve this problem predetermines the task of replacing fossil energy sources with renewable alternatives. The process of the ongoing transformation is called energy transition. It includes transformation of all the energy-intensive sectors of economic activity: power generation, supply and consumption, heat generation and supply, electrification of transport, agriculture and households. The main goal of the energy transition is obvious – it is necessary to reduce the emissions of carbon dioxide into the atmosphere. The main sources of energy used to achieve this goal in power generation are wind and solar energy. Even though the goal is unambiguously defined and the way to achieve it seems evident, it is already clear that a number of serious problems and obstacles have arisen. They are caused by the emergence of additional objectives that must be achieved and constraints that need to be satisfied in the process of the required transformations. Indeed, the transition should be carried out taking into account power system properties describing techno-economic efficiency, reliability, stability, adequacy, etc. This list can be expanded easily. It should be noted that the additional objectives are not less important than the overarching goal. Along with reducing emissions, it is also necessary to improve energy supply reliability, its availability and affordability for all the segments of the population as well as maintain the security of the energy supply infrastructure and processes.
