Vannamei shrimp farming is a strategic industry in the coastal area of Cilacap that requires a sustainable energy supply. Wind Power Plants (PLTB) emerge as an interesting alternative to meet these energy needs. This research aims to conduct an optimal PLTB design analysis using the Homer Application in Vannamei shrimp farms. The objectives are: (1) to determine the appropriate type of wind turbine for pond aquaculture in the coastal area of Cilacap, (2) to assess the amount of electrical energy generated by PLTB in pond aquaculture in the coastal area of Cilacap, and (3) to evaluate the capabilities of PLTB in the aquaculture sector in terms of economic feasibility and efficiency. The research methodology involves field surveys to collect data related to the energy needs of Vannamei shrimp farms and the environmental characteristics of the coastal area of Cilacap. This data is then used as input in the Homer Application to design a PLTB system that aligns with the energy needs and local environmental conditions. The analysis results indicate that PLTB can be an efficient and sustainable solution to meet the energy needs of Vannamei shrimp farms in the coastal area of Cilacap. The Homer Application aids in determining the optimal configuration of PLTB, including the selection of location, type of wind turbine, capacity, and power distribution devices. The study reveals that the Karangtawang area in the Nusawungu Subdistrict, Cilacap Regency, has sufficient wind potential to generate electrical energy with an average wind speed of approximately 4.026 m/s. The selected wind turbine for Vannamei shrimp farms is the AWS HC 1.8kW, and the simulation results in the Homer system indicate that using two turbines can generate 5.178 kW/year of electrical energy. The simulation also produces an excess electricity of 11.3%. A lower excess electricity value indicates better system performance because almost all generated energy is utilized and not wasted.
