Techno-economic Analysis of 100 kWp Floating Solar Photovoltaic for Renewable Energy Mix in Bali – Indonesia

Abstract

To achieve renewable energy mix target and support the Indonesian Government’s policy on the use of solar power, PT. PLN Indonesia Power Bali has installed Floating Solar Photovoltaic (PV) above the surface of the Muara Nusa Dua reservoir. The 100 kWp Floating Solar PV was showcased at the G20 meeting held in Bali. In this study, a techno-economic analysis was carried out for the 100 kWp Floating Solar PV. The data collected was the real time data from the production of the 100 kWp Floating Solar PV and the costs incurred for the investment. The results of this study showed an average energy yield of 145.93 MWh with expected revenue of Rp 236,406,729.60 annually. Furthermore, the NPV and IRR were calculated and the resulted values were Rp 2,810,168,240.00 and 5.73 %, respectively with payback period approximately of 13 years. This showed that the 100 kWp Floating Solar PV is feasible investment to increase renewable energy mix in Bali – Indonesia.
