The potential for New Renewable Energy (EBT) in Indonesia is quite large, including mini/micro hydro potential of 450 MW. The development of microhydro technology which is still low in Indonesia is complicated by the obstacles of climate change. As a tropical country, climate change has a big impact on rainfall and water availability, thereby affecting future micro-hydro potential. It is very important to analyze the impact of climate change and climate variability on hydroelectric power plants. This study predicts the amount of power production from MHP in a climate change scenario using the CanESM5 climate model predictor in the Upper Citarum Watershed - Cikapundung Sub Watershed area, as one of the highland areas considered to have potential for micro-hydro development. Climate change parameters in the form of rainfall are the observed variables. SDSM software is used in the downscaling method. Obtained 3 different selected predictors for each rain station. Rainfall at 5 stations has a correlation with air humidity, shown by the specific humidity predictor at each station. Predicted rainfall for 2024-2053 at each rain station which has been corrected with linear scaling is used as input to the SWAT hydrological model to obtain estimated river discharge. The combination of geographic information system (GIS) and SWAT methods provides potential location point output for MHP and power prediction. There are at least 3 potential locations in the same sub-basin with a total power potential of 297-512 kW in the Cikapundung watershed.
