Impacts of Climate Change on Hydroelectric Power Generation – A Case Study Focused in the Paranapanema Basin, Brazil

Abstract

Climate change is taking special attention among the economic agents, especially due to the uncertainties and risks associated with it. In countries with a significant share of renewables in their energy matrix, this phenomenon implies on challenges for the energy planning in future scenarios. In this context, this study establishes a correlation between energy security and climate change by understanding the ability to generate hydroelectric power in large-scale hydroelectric (HEP) and small hydroelectric plants (SHP), in the Alto Paranapanema Basin (São Paulo, Brazil), a region with rainfall anomalies and water flow changes due to climate change. This region was chosen based on its future scenarios on climate change, especially those of rainfall anomalies and change in water flow, using the Soil Moisture Accounting Procedure (SMAP) mathematical model. The water flow was simulated in the HidroLab model, resulting in the generation of hydroelectric power. The results indicated a loss of generation capacity, that can be attributed to negative anomalies of rainfall and its direct influence on river flow, which is a fundamental factor in hydropower generation. Thus, this study draws attention to the importance of considering climate vulnerability in energy planning now and in the future.

Impact of extreme events on conversion efficiency of wave energy converter

“…All these scenarios consider the continuous growth in population where rate of growth in A is higher compared to B-type scenarios. In recent years, climatic data are generated based on the IPCC SRES scenario and used in various studies like for projecting future climate changes over upper Indus river basin, 57 to find the impact of future climate change on regional crop water requirement, 58 the analysis of impacts of climate change on various renewable energy resources, 59,60,61,62,63,64 and many other studies involving climate change impact analysis. In the present investigation, the impact of extreme events was analyzed for a location situated in Southern Indian peninsula.…”
