Abstract

Pada tahun 2021, prosentase nilai daya Pemakaian Sendiri di PLTU Tanjung Jati B mencapai 5,25% atau setara 543 GWh. Instalasi PLTS Rooftop 32 kWp di gedung kantor PT. KPJB telah selesai dan diharapkan mampu menggantikan peran suplai energi listrik dari PLTU. Namun belum diketahui pasti apakah PLTS 32 kWp mampu memenuhi kebutuhan beban listrik di gedung kantor PT. KPJB serta bagaimana nilai performa yang dihasilkan. Pada penelitian ini, kajian kelayakan teknis dilakukan dengan menghitung nilai performance ratio (PR) sebagai indikator kinerja dari PLTS 32 kWp. Hasil aktual tersebut dibandingkan dengan nilai proyeksi dari hasil simulasi PVSyst 7.2. Kajian kelayakan ekonomi juga dilakukan untuk mengetahui nilai alur kas serta prediksi balik modal dari investasi PLTS 32 kWp. Hasil simulasi PLTS 32 kWp memproyeksikan produksi listrik mencapai 35,88 MWh dengan nilai Performance Ratio 83,09% dalam setahun. Pada kondisi aktual selama 9 bulan operasi, produksi PLTS 32 kWp aktual mencapai 29.504,77 kWh dengan nilai performance ratio aktual 83,82%. Sedangkan hasil kajian kelayakan ekonomi menunjukan bahwa implementasi PLTS 32 kWp dikatakan layak dan periode pengembalian modal akan jatuh di antara tahun 2038 hingga 2039.
Kata Kunci: PLTS, Performance Ratio, Investasi

In 2021, the percentage of self-use power at Tanjung Jati B CFPP reaches 5.25% or around 543 GWh. Installation of Solar Power Plant Rooftop 32 kWp in the office building of PT. KPJB has been completed and is expected to be able to replace the role of electricity supply from the CFPP. However, it is not known for sure whether the Solar Power Plant is able to meet the needs of the electrical load in the Office and how the performance value is generated. In this study, a technical feasibility study was carried out by calculating the performance ratio (PR) value as a performance indicator for Solar Power Plant 32 kWp. The actual results are compared with the predicted values from the PVSyst 7.2 simulation results. An economic feasibility study was also carried out to determine the cash flow value and payback period of Solar Power Plant investment. The simulation results project electricity production to reach 35.88 MWh with a Performance Ratio value of 83.09% in a year. In actual conditions during 9 months of operation, Solar Power Plant 32 kWp production reached 29,504.77 kWh with an actual performance ratio value of 83.82%. While the results of the economic feasibility study show that the implementation of Solar Power Plant 32 kWp is feasible and the payback period will be between 2038 and 2039.
