Study on PV System Development at UP Brantas for Hydroelectric Power Plant Station Service Supply

Abstract

Concern toward the preservation of natural resources became one of the attention for the generation industry in Indonesia. Thus the development of renewable energy in the generation sector is important. Several hydropower plants of UP Brantas have the potential to develop PV systems in the Kolam Tando Harian (KTH) and the tailrace area. The hydropower as the object of this study, the average needed for the hydropower electricity station service per year can be calculated by calculating the PV system with 5% - 80% of the potential area that has been determined. Due to the station service costs of hydroelectric power stations increases at 0.172 $/kWH, the development of PV systems is an alternative solution to reduce the cost of hydropower station service. Refers to the capital cost of PV & energy storage issued by Lazard in 2019, it is known that the LCOE value for PV development in UP Brantas hydropower ranges between 0.11 - 0.21 $/kWH. Compared to the import energy tariff of 0.172 $/kWH, the development of this PV plant is potential and realistic to implement. This program is aligned with government and company policies in realizing the strategic goals of renewable energy development. The development of this PV plant can be integrated later into the hydropower load center using a hybrid decentralized grid-connected PV system configuration with or without battery energy storage.
