Abstract
The primary force behind human civilisation is energy. The development of renewable energy as an alternative energy source, including solar energy, is encouraged by the rising depletion of fossil fuels and the numerous negative effects that follow. The goal of this study is to examine the growth of solar power plants (PLTS) as a source of electrical energy in public buildings in numerous Indonesian cities, including Semarang, Bandung, Surabaya, Jakarta, and Yogyakarta. The Hybrid Optimization Model for Electric Renewable (HOMER) software was used to simulate and optimize the design. The research was designed with an assumed electricity load of 3002.87 kWh/day and the project was assumed to run for 25 years. It was found that the city with the most potential with this design configuration was Semarang City. The initial investment cost required to configure this system is IDR 4,329,377,867.29. This city is able to produce electricity of 1,037,881 kWh/year, while total electricity consumption reaches 963,762 kWh/year. In addition, the NPC value of around IDR 27,543,680,000.00 and the COE value of around IDR 1,256.87 indicate good investment feasibility, with BEP in the 15.90th year.
