Feasibility Study Analysis of Hybrid Power Plant: Case Studies of Biomass and Solar PV at Bangka Island

In 2021, the Indonesia New Renewable Energy (NRE) mix achievement was 11,5% while the target for NRE mix targeted by Ministry of Energy and Mineral Resources (ESDM) in 2025, 2030, and 2050 was 23%, 25%, and 31%. On Bangka Island, current NRE power plant installed capacity was 11,2 MW or 4,6% from total energy mix in Bangka – Belitung Islands Province, whereas Government of Bangka – Belitung Islands Province through Rencana Umum Energi Daerah (RUED) 2019 – 2050 planned to increase NRE mix at least 31,42% until 2025 with NRE power plant installed capacity at least 246,44 MW, and at least 39,31% until 2050 with NRE power plant installed capacity at least 560 MW. This paper presents analysis to seen potential of generated electricity and Life Cycle Cost (LCC) & Levelized Cost of Energy (LCOE) of NRE power plant with types of Biomass Power Plant fueled by Empty Fruit Bunches (EFB) and Ground Mounted Solar PV on Bangka Island. The result of this analysis indicates that potential of generated electricity from Biomass power plant fueled by EFB was 443,401 GWh/year according to availability of EFB on Bangka Island and potential energy production from Solar PV was 0,721 kW/m2/day according to solar radiation on Bangka Island and efficiency of solar panel, inverter, and other equipment efficiency. LCC for 10 MW Biomass power plant was IDR 557.386.383.703 with LCOE IDR 544,37/kWh, also LCC for 2 MW Solar PV Power Plant was IDR 48.949.012.349 with LCOE IDR 1.336,54/kWh. LCOE for hybrid biomass and solar PV power plant system is Rp. 940,459/kWh. The LCOE of hybrid system is less than PLN electricity tariff limit on Bangka Island which is Rp. 2.006,52/kWh or cent USD 13,77/kWh.
