“…Global warming will directly affect the quality and quantity of water resources, constituting important factors for the hydropower production potential [32]. One of the factors sensitive to climate change in hydropower plants is the value of the input flow to the reservoir [33]. The obtained results confirm the aforementioned concerns regarding hydropower production, where its successive decrease results from the unfavorable meteorological-hydrological situation observed in the analyzed multiannual period.…”

This paper presents the impact of flow changes in the Warta River and water management rules regarding the Jeziorsko dam reservoir on the energy production by the hydropower plant in the period 1995–2021. The Jeziorsko dam reservoir was built in 1986. It is the second largest dam reservoir in Poland in terms of surface area. In 1994, a hydropower plant with an installed capacity of 4.89 MW started operation. The study results show the average annual energy production from 1995 to 2021 at a level of 18,718 MWh. On the other hand, energy production largely changed from year to year, from 12,432 MWh (in 2019) to 26,916 MWh (in 2001). The droughts that have occurred in the Warta River basin over the past two decades have had a major impact on energy production. As a consequence of the drought, it was not possible to maintain the required water level in the reservoir. Moreover, a change in the rules for the reservoir’s management that led to lower water levels in the reservoir by 1.5 m between April and June was important from the point of view of energy production. Improving the efficiency of energy production requires changing the rules of water management in the reservoir. More flexible reservoir operation schemes should be considered, including operational management based on meteorological and hydrological forecasts. Moreover, other criteria should also be considered, such as maintaining environmental flows, ensuring protection from flooding, and operating a nature reserve around the reservoir.

“…Their findings were in agreement with [ 105 ] who also stated that CC is responsible for global water shortages. Also [ [ 42 , 106 ]],stated that CC is responsible for the increase in the severity of extreme rainstorms and extreme floods. Furthermore [ [ 104 , 105 ]], believethat CCcan have a significant impact on hydropower plants, which can lead to a decrease in the amount of power produced by hydroelectric dams.…”

“…Climate change and intensive human activities have changed the temporal and spatial distribution of water resources in these areas, and significantly affect local hydropower generation. Reservoir regulation is an important measure to realize normal operation and redistribute water resources in time and space [7,8]. Therefore, predicting the river runoff and hydropower generation process under the conditions of future climate change has scientific significance for deeply understanding the water resource evolution.…”

Climate warming accelerates the hydrological cycle, especially in high-latitude and high-altitude areas. The increase in temperature will increase the amount of snow and glacier melting and change the runoff, which will affect the operations of cascade reservoirs significantly. Therefore, taking the upper reaches of the Yellow River with an alpine climate as an example, we propose an improved SIMHYD-SNOW, which considers the snowmelt runoff process. The impacts of climate changes on the runoff process were revealed based on the SIMHYD-SNOW model using the precipitation and temperature data predicted by the SDSM model. A model for the maximum power generation of the cascade reservoirs in the upper reaches of the Yellow River was constructed to explore the impacts of climate changes on the inter-annual and intra-annual hydropower generation of the cascade reservoirs at different periods in the future. The results show that climate change has changed the spatial and temporal allocation of water resources in this area. The future runoff will decrease during the flood period (July to September) but increase significantly during the non-flood period. The inter-annual and intra-annual hydropower generation under the RCP8.5 climate change scenario is significantly lower than the RCP2.6 and RCP4.5 climate change scenarios, and as the CO2 emission concentration increases, this gap increases significantly. This study can provide technical references for the precise formulation of water resources management under climate change.
