ANALISIS POTENSI TENAGA SURYA SERTA PERANCANGAN PEMBANGKIT LISTRIK TENAGA SURYA (PLTS) DI PANTAI SAMAS, BANTUL

The more developing times in the era of modernization, the need for electrical energy is increasing. However, the electrical energy used is still dominated by fossil fuel power plants. By conducting research on the analysis and planning of power plants sourced from renewable energy, one of which is Solar Power Plants, Solar Power Plants are expected to be one of the alternative sources of electrical energy to address the increasing demand for electrical energy. The analysis and design of the PLTS system at this time can use the assistance of the Hybrid Optimization Model for Electric Renewable (HOMER) software. By using the HOMER software, it can simulate the load of electrical energy per day and the intensity of solar radiation. The HOMER software can also simulate the results of electrical energy obtained from solar panels, the emissions and costs required for the construction of a power plant. The results of the analysis based on the HOMER software, the potential for solar radiation intensity an average of 5,635 kWh / m2 / day and the total power requirement of 1,889.6 kW / day with a peak load of 283.43 kW. From the design results using the HOMER software, the optimal configuration is obtained using a solar panel with a capacity of 690 kW, a battery of 5,784 kWh, and 3 inverter units with a capacity of 100 kW. The total investment cost used in designing this PLTS system is IDR 47,173,913,170.40 with 100% investment without subsidies, investment costs IDR 40,131,542,742.30 with 75% investment and 25% subsidies while investment costs IDR 31,967,124,413, 54 at 50% investment cost and 50% subsidy. As for the cost of the selling price of electrical energy or Cost Of Energy (COE) with an investment of 100% Rp3,573 per kWh, 75% investment with a 25% COE subsidy of Rp3,040 per kWh and 50% investment with a 50% subsidy of COE 2,421 per kWh. With this system configuration it produces 0 CO2 emissions.
