The State of Food Security and Nutrition in the World (SOFI) report reveals the stark reality that, overall, the world has made little progress in ensuring universal access to safe, nutritious, and sufficient food throughout the year. To address this problem, agriculture plays a pivotal role in sustaining food supply and achieving SDG2, which aims for Zero Hunger by 2030. However, greenhouse farming, which is a solution to meet the increasing demand for food, requires ten times more energy consumption compared to traditional farming. Therefore, this paper proposes a hybrid power system (solar+wind+generator-based) to fulfill the operational electricity needs of greenhouses. The study focuses on the potential of renewable energy generation in the village of Hambapraing, East Nusa Tenggara. The findings demonstrate that a hybrid system can meet the greenhouse's daily load requirement of 289,480 kWh, providing the necessary energy supply. The optimized hybrid system architecture, obtained through HOMER optimization, yields an annual electric power production of 180,955 kWh. This consists of 72.6% from solar energy, 42.909% from wind energy, and 3.66% from the generator. The designed hybrid system has a total net present cost (NPC) of Rp7,016,869,000.00, an initial cost of Rp4,082,241,571.30, and a levelized cost of energy (LCOE) of Rp2,920.59. This design ensures a reliable and affordable power supply for the greenhouse while reducing the operational costs associated with its electrical needs.
