Abstract
The real action to mitigate the impact of climate change is to carry out an energy transition from fossil energy to new and renewable energy (NRE). One source of NRE for Indonesia's future is ocean current energy, which requires careful study of energy, technological, economic, environmental, and social potential aspects.
This paper describes the techno-economic analysis of a floating ocean current power plant (FOCPP) by applying a ducted turbine array system of various sizes according to local bathymetric conditions. Techno-socio-economic analysis of power plants includes ducted turbine energy performance, annual energy production (AEP) value, capital expenditure (CAPEX) and operational expenditure (OPEX), net present value (NPV), and Levelized Cost of Energy (LCOE) as well as payback period (PBP). The analysis was carried out based on the results of testing the ducted turbine prototype in the Haya Strait, Maluku Islands. The analysis results show that the Haya Strait FOCPP has an energy and economic development perspective by applying ducted tidal turbines with a diameter of 1–5.5 m in a six block array. AEP ∼141,145.6 MWh with a Ravg value of ∼204,946,301 (million Rupiah). Gross initial investment costs ≥300 billion Rupiah and PBP ≥6.3 years. FOCPP for small islands is suitable for entering the industrialization and downstream stages.
