Techno economic study of floating solar photovoltaic project in Indonesia using RETscreen

• Indonesia aims for net-zero emissions by 2060 amid energy overgeneration. • This research aims to analyze feasibility of floating solar PV in Cirata. • This study assesses feasibility of Cirata 145 MW floating solar PV with RETScreen • The result shows a comparison significance of parameter that effects the project feasibility. • This study is the first study on floating solar PV in ASEAN's techno-economic feasibility. The utilization of solar energy is crucial for the advancement of sustainable power generation on a worldwide scale, driven by environmental concerns and the depletion of fossil fuels. Indonesia's goal is to achieve carbon neutrality by 2060 and it is aggressively advocating for solar energy, which includes the implementation of new methods such as floating photovoltaic (PV) systems. This study evaluates the Techno-Economic Feasibility of Indonesia's Cirata 145 MW floating solar PV project by employing RETScreen technology. The objective is to improve the long-term financial stability, decrease greenhouse gas emissions, and suggest viable choices for improvement. Examining three scenarios that involve alterations in carbon emissions, energy pricing, and loan interest rates demonstrates different levels of project feasibility. The introduction of carbon tax emission pricing has a substantial impact on the feasibility of projects. This study provides useful insights into doing techno-economic feasibility assessments using RETScreen for floating photovoltaic (PV) systems. It demonstrates how modifying parameters can effectively mitigate project risks.
