STUDI PERENCANAAN SISTEM PEMBANGKIT LISTRIK HYBRID (PLTB DAN PLTS) SEBAGAI SUMBER ENERGI DI PERMUKIMAN TRANSMIGRASI DESA TOKALA ATAS, KABUPATEN MOROWALI UTARA BERBASIS SIMULASI HOMER

Abstract

The Transmigration Settlement of Tokala Atas Village, North Morowali Regency, still experiences limited electricity supply characterized by power outages and voltage drops, thus requiring a more reliable alternative energy source. This study aims to design and analyze a hybrid Wind Power Plant–Solar Power Plant (PLTB–PLTS) system as a solution for energy provision in the area. The methods used include manual calculations as well as system simulation and optimization using HOMER Pro to obtain the optimal technical and economic configuration. Based on manual calculations, the total annual energy production of the PLTB–PLTS system is 187,383 kWh/year. After optimization, in Scenario 1 (PLTB–PLTS) the total energy production becomes 165,904 kWh/year, while in Scenario 2 (PLTB–PLTS–PLN) it increases to 335,777 kWh/year. From an economic perspective, the manual calculation results in a Total NPC of IDR 8,542,099,000.00 with a COE of IDR 4,134.18/kWh. Scenario 1 produces a Total NPC of IDR 5,139,394,000.00 with a COE of IDR 2,591.60/kWh, and Scenario 2 results in a Total NPC of IDR 3,411,163,000.00 with a COE of IDR 813.32/kWh. The results indicate that the PLTB–PLTS–PLN configuration in Scenario 2 provides the highest energy production and a more stable and reliable system in meeting the electrical load demand at the study location.
