The development plan of a nickel smelting industry in the North MalukuNorth maluku province requires a high supply of electricity. On the other hand, the low availability of clean electricity and the disparity in electricity supply between islands continue to be challenges for the power sector in North MalukuNorth maluku. Hence, there is an urgency to explore renewable energy, for instance tidal currents energy as a renewable energyRenewable energy source, to address the energy availability issues while aligning with sustainable development goals (SDGs) 7, 9, 10, and 13. Therefore, further studies are needed to explore the technical and financialFinancial analysis aspects of tidal currents energy development. This research aims to analyzeAnalyze the potential for extracting tidal currents energy as a power generator in the Patinti strait, using a 10-m diameter transverse horizontal axis water turbine (THAWTTransverse Horizontal Axis Water Turbine (THAWT)). With its blade design, THAWTTransverse Horizontal Axis Water Turbine (THAWT) is significantly more effective at converting kinetic energy from ebb and flood currents. Based on the financialFinancial analysis feasibility analysis, the construction of tidal currents power plantPower plant is financially viable. The electricity generation costs are competitive with regional electricity prices in North MalukuNorth maluku. Therefore, the utilization of tidal currents energy is expected to provide a clean energy supply for both industrial and household needs.
