Spatial optimization of the economic benefits of the potential hydropower locations: study case upper citarum river

Abstract

Hydropower is a renewable energy source that provides clean energy services and contributes to climate change mitigation by replacing fossil fuel energy production sources. The Upper Citarum Watershed in West Java, Indonesia, is described as a giant basin known as the Bandung Basin, which is type by mountainous relief with an elevation of 750-2300 meters above sea level, a slope of 30-90%, and a radiating river flow pattern. This study focuses on the potential of small hydropower with a run-of-river scheme that acts as a filler for the study of hydropower potential with a pump storage scheme by the Australian National University. Climate data in the study area were analyzed using the SWAT model to obtain Cumulative Discharge Frequency and identify potential discharge by adopting the method of previous studies. The results identified 7 SHPs with P exceeding 500 kW and below 2000 kW. BHUMI ATR BPN can predict land value and land cover in areas designated for hydropower development. The findings suggest improvements in aspects such as proper forecasting, on-the-ground valuation, and calculations relating to economically viable sustainability.
