Techno Economic Analysis of Hybrid Sea Floating Photovoltaic and Wind Turbine for Fish Cold Storage at Remote Island in Indonesia (Case Study: Small Kei Island, Maluku, Indonesia)

Most of fisherman in Small Kei Island, Indonesia, are difficult to keep the good quality of fish for several days because unavailability of Fish Cold Storage. Due to the area is also far from grid, this paper is aimed to analyse the most optimized sizing of integrating the new technology of sea floating photovoltaic and wind turbine to achieve the minimal levelized cost of energy for powering 100 tons of fish cold storage. Ten scenarios with implemented off-grid scheme by dividing battery bank into two equal parts that will be operated interchangeably to meet 24 hours load requirement on hybrid sea floating photovoltaic and wind turbine system are performed. As result, 100 kW of wind turbine and 803kWp of sea floating photovoltaic are chosen with the most minimal levelized cost of energy of USD 0.52/kWH by life cycle cost method of 20 years. With define electricity tariff of USD 0.81/kWH and interest loan of 9%, the economic analysis result fulfil of four indicators requirement with payback period of 6 years 6 months 20 days, net present value of USD 10,981, internal rate of return of 9.10%, and profitability index of 1.60.
