The Spatial Analysis of the Potential and Development Opportunities for Ocean Current Power Plants (OCPP) in Lombok Strait

Abstract

Entering an era where demand for electricity is increasing, renewable energy sources like the Ocean Current Power Plant (OCPP) are crucial for nations like Indonesia. The Lombok Strait, a key channel for the Arus Lintas Indonesia (ARLINDO) or Indonesian Throughflow, stands out as a strategic location for this technology due to its powerful currents. These currents have a minimum speed of 4.4 m/s and a maximum of 5.8 m/s, averaging around 5.34 m/s. This study sought to pinpoint suitable areas for OCPP development within the strait using a qualitative geographical approach, analyzing literature and satellite data. The research confirmed that current speeds ranging from 4.44 to 5.8 m/s could produce an average of 25.92 kW of power, equivalent to 181,647.36 kWh annually. Ideal locations for turbine placement ranging from 0 to 75 meters offshore, in water depths varying from 0 to -100 meters. Therefore, the study emphasizes the need for careful site selection using suitability maps and calls for further research into an effective power distribution system to successfully harness the strait's energy potential.
