Abstract

The planning and development of solar power plants is one of the renewable energy and government’s key initiatives to support Indonesia’s national vision of achieving Net Zero Emissions by 2060. To optimize the implementation of the floating PV project at Lake Singkarak, West Sumatra, three scenarios with different planned capacities were proposed: Scenario 1 with 92 MW, Scenario 2 with 184 MW, and Scenario 3 with 276 MW of installed floating PV capacity. A comprehensive techno-economic study was conducted to analyze these three scenarios. The analysis concluded that Scenario 2 is the most optimal, achieving a Levelized Cost of Electrical (LCoE) of 825,47 IDR/kWh, and maintaining system stability with a frequency of 49,3 Hz during simulations involving sudden weather changes that caused a temporary loss of electricity generation from the floating PV system.
