Abstract

The reliable discharge calculation for forecasting discharge entering the Jatiluhur Reservoir uses the Thomas Fierring method. In this study, a rapid assessment was carried out on the effectiveness of the PSPP in the Jatiluhur Reservoir in 2040 by also considering changes in water demand downstream of Jatiluhur in 2040. A pumped storage power plant (PSPP) is a renewable energy storage medium for electrical energy. A rapid assessment was carried out on the calculation of the energy and volume produced with the operational hours, the condition of the reservoir being full (+ 106.5 m) and the condition of the reservoir approaching the minimum operating limit (+ 90 m). Based on the study’s results, PSPP at the Jatiluhur Reservoir will produce additional electrical energy of 2,180,763 kWh with a water volume requirement of 6,669,000 m³/day and operational is 2,85 hours. The operational of PSPP will reduce the Water High Level (WHL) of the Jatiluhur Reservoir by 0.12 m (full-time condition) and 0.15 m (minimum operating limit reservoir condition). With the PSPP, it is known that the Jatiluhur Reservoir can still operate normally so that the PSPP can increase electricity production without significantly reducing the WHL and volume of the Jatiluhur Reservoir.
