With the increase in population is also proportional to the demand for electrical energy and reduced fossil energy. To support the public demand for electricity supply, it needs renewable energy as a power plant. Renewable energy as a power plant such as wind energy. The potential of wind energy in Indonesia according to LAPAN, on the southern coast of Java island ranges from more than 5 m / s and is able to generate electrical energy of 100 kW more. In addition, wind energy as a power plant is also able to reduce CO2 emissions in Indonesia. Therefore the analysis of the potential of wind resources in Samas Beach is the South Coast of Java Island. The analysis used Homer software to simulate the daily population load and wind speeds that blow. Homer is able to simulate the results of the generated energy, emissions, and costs for the construction of the Samas plant. PLTB Samas able to become an alternative energy in the supply of electrical energy in the coastal area of Samas Beach. The data obtained are simulated in Homer software. The average wind speed in Samas Beach in one year is 5.64 m / s. Based on simulations generated by the Homer software, the best configuration for the PLTB system uses 30 wind turbines, 20 batteries, and a 50 kW converter. With such a configuration capable of generating CO2 emissions of 0, capable of being a clean energy supply compared to a system from PLN that produces CO2 emissions of 854 grams per kWh. The configuration is capable of generating 73.467 kWh of electricity per year with a primary load of 30,441 kWh per year, with the assistance of a grid system of 11,818 kWh per year so that it has an energy surplus of 52,955 kWh per year which can be utilized for other load suppliers or sold to PLN.
