Analysis of the hybrid power plants of PLTD and PLTS on Tidung Island, Seribu Islands, DKI Jakarta using homer.

Tidung is a remote area far from urban areas in the South Thousand Islands, DKI Jakarta. The primary source of electrical energy in Tidung Island is the system supplied by PT. PLN through submarine cables, where fossil fuels are still used to generate electricity. This study aims to integrate fossil fuel diesel with PLTD as a hybrid production system to create energy on Tidung Island by supplying PLTD fuel to Tidung Island. Therefore, this study aims to test the technical and economic feasibility of PLTH using the HOMER application. Based on the simulation results, it is known that PLTH (PLTS, PLTD, Grid PLN) is technically possible. PLTH can produce 261.967 kWh of power per year, whereas the electricity demand on Tidung Island is 43,800 kWh/per year. After PLTD was hybridized with PLTS, the percentage of loading on the hybrid system was 75.9% (198,942 kWh/year) from PLTS, O.66% (1,747 kWh/year) from PLTD, and 23.4% (61.279 kWh/year) from Grid PLN. From an economic point of view, the planned NPC of PLTH on Tidung Island is Rp.3,972,953,000 lower than PLTD + Grid PLN before being hybridized to PLTS, which is Rp.11,684,970,000. Meanwhile, the LCOE of PLTH planned for Tidung Island is lower than that of PLTD + Grid PLN on Tidung Island. It costs Rp.1,671.72/kWh for PLTH and Rp.13,193.80/kWh for PLTD + Grid PLN. So, it can be said that the PLTH planned for Tidung Island is more feasible to operate than PLTD + Grid PLN because, from an economic point of view, the costs incurred are cheaper than PLTD + Grid PLN.
