Unravelling the water-energy-economics-continuum of hydroelectricity in the face of climate change

摘要: This study is aimed at evaluating the impacts of climate change (CC) on the water-energy-economics-continuum considering a storage type hydroelectricity project (STP). Inflows from ensembled CC scenarios for two RCPs (4.5 and 8.5) and three time-windows (near-future, mid-future, far-future) until the end of this century, generated from an earlier study by the same team, was used for the analysis. The proposed 1200 MW Budhigandaki Hydropower Project in Nepal is taken as a case. A set of reservoir operating rules were derived considering the baseline data which was then used to generate future energy and revenue at the monthly, seasonal and annual timescales. Results show that future annual energy is expected to increase by about 9–13% from the baseline. Furthermore, future revenue generation is projected to increase in the range of 20–28 million USD annually. This overall gain in the revenue due to …
