Finally, this paper concludes that technically, the application of PV grid-connected technology in Indonesia power system is proves to be suitable. This opens the opportunity for the technology to significantly contribute to the expedited National target in PV development. "

"Energi surya merupakan salah satu sumber energi terbarukan yang tersedia melimpah dan ramah lingkungan terutama di negara tropis. Penggunaan pembangkit listrik tenaga surya semakin bervariasi, baik dalam bentuk pembangkitan besar-besaran di daerah yang luas dan terpencil maupun di tempat-tempat umum yang bertujuan untuk mengurangi ketergantungan pada pembangkit listrik yang praktis. Pada penelitian ini dilakukan simulasi perancangan PLTS on-grid di Kantin Fakultas Teknik Universitas Indonesia dengan pengujian dengan 2 metode yang berbeda. Metode pertama adalah perancangan berdasarkan beban harian pada kantin on-grid dan cadangan baterai on-grid, yang kedua adalah pemanfaatan area yang dapat dipasang panel surya on-grid dan baterai cadangan on-grid. Penelitian ini bertujuan untuk melihat tingkat kelayakan teknis dan ekonomis dari rancangan ini. Dari hasil analisis dapat disimpulkan bahwa metode perancangan PLTS berdasarkan on-grid area yang tersedia menghasilkan tingkat keandalan ekonomi yang paling baik, dimana sistem ini dapat memberikan kontribusi penyediaan energi listrik sebesar 68,98% dari beban hari kerja dan 182,18%. dari beban. hari libur, dan dapat menghasilkan potensi energi sebesar 16.063 kWh per tahun.

Solar energy is one of the renewable energy sources that is abundantly available and environmentally friendly, especially in tropical countries. The use of solar power plants is increasingly varied, both in the form of large-scale generation in large and remote areas and in public places with the aim of reducing dependence on practical electricity generation. In this study, a simulation of the on-grid PV mini-grid design was carried out at the Canteen of the Faculty of Engineering, University of Indonesia by testing with 2 different methods. The first method is a design based on the daily load on the on-grid canteen and on-grid battery backup, the second is the utilization of the area that can be installed on-grid solar panels and on-grid backup batteries. This study aims to see the level of technical and economic feasibility of this design. From the results of the analysis, it can be concluded that the PLTS design method based on the available on-grid area produces the best level of economic reliability, where this system can contribute to the supply of electrical energy by 68.98% of the workday load and 182.18%. from the load. holidays, and can generate energy potential of 16,063 kWh per year."

"Sebagian besar kebutuhan listrik di Kalimantan Barat di impor dari Sarawak, Malaysia karena kurangnya pembangkit listrik yang andal disana. Studi ini mengusulkan pendekatan alternatif untuk meningkatkan ketahanan energi nasional dan penghematan energi dengan menerapkan sistem PV surya atap untuk industri kelapa sawit, dimana di Kalimantan Barat sektor industri merupakan sektor yang akan berkembang masif dimasa mendatang. Studi ini mengevaluasi kelayakan penerapan sistem PV surya atap on grid di industri kelapa sawit dengan mengevaluasi luasan atap yang tersedia dan optimasi sistem. Luasan atap yang di-evaluasi layak untuk menampung 105 kWp PV surya untuk memenuhi permintaan beban puncak industri pada siang hari. Penyelidikan potensi penghematan energi diperkirakan 146.459 kWh setiap tahunnya dan jika semua industri kelapa sawit di Kalimantan Barat dipertimbangkan, potensi penghematan energi akan menjadi 10.252.130 kWh yang lebih rendah dari harga listrik utilitas (PLN). Dalam hal investasi proyek, sistem ini dapat menghasilkan IRR sebesar 7,2% dan periode pengembalian modal yang sederhana selama 12 tahun. Penelitian ini juga melakukan analisa sensitivitas dengan mengevaluasi skema Feed in Tariff (FIT) yang mengakibatkan IRR meningkat dan LCOE yang lebih rendah.

Most of electricity demand in West Kalimantan is imported from Sarawak, Malaysia because of the lack of reliable power plant in the region. This study proposes an alternative approach to increases national energy security and energy savings by implementing rooftop solar PV system for CPO (Crude Palm Oil) industry due to the furhter development of industry sector in West Kalimantan in the future. The paper goes ahead to evaluate the feasibility of implementing grid-tied rooftop solar PV system in CPO industry by evaluating suitable rooftop area and system optimization. For the considered rooftop, it is feasible to accommodate 105 kWp of solar PV to fulfill the peak load demand of the industry during the day. The investigation of potential energy savings is estimated for 146,459 kWh every year and if all CPO industry in West Kalimantan are considered, the potential energy savings would be 10,252,130 kWh every year. The economic analysis of solar PV system is resulted in LCOE of Rp878.93/kWh which is lower than the utility grid price. In terms of project investment analysis, the system could generate IRR of 7.2% and simple payback period of 12 year. This study also performed sensitivity analysis by evaluating Feed in Tariff (FIT) scheme that resulting in the increasing of IRR and lower LCOE."

"Permintaan akan energi, khususnya energi listrik, di Indonesia semakin tinggi dan menjadi bagian tak terpisahkan dari kebutuhan hidup masyarakat dan sektor industri. Namun, ketersediaan bahan bakar fosil yang digunakan untuk menghasilkan listrik semakin terbatas, serta polusi yang dihasilkan oleh proses konversi dari bahan bakar fosil tersebut. Indonesia memiliki potensi energi surya sebesar 207,8 GWp Namun, potensi ini belum dimanfaatkan secara optimal. Oleh karena itu, potensi tersebut dapat dioptimalkan dengan instalasi PLTS atap pada bangunan dengan konsumsi listrik tinggi. Gedung MRPQ Universitas Indonesia dengan konsumsi listrik yang relatif tinggi dijadikan sebagai lokasi studi. Penelitian bertujuan untuk mengetahui konfigurasi dan skema paling optimal berdasarkan Net Present Cost (NPC) dan beberapa parameter ekonomi seperti Net Present Value (NPV), Internal Rate of Return (IRR), dan Payback Period. Pada HOMER, dilakukan simulasi dengan konfigurasi On-Grid dan Off-Grid. PLTS On-Grid disimulasikan dengan variasi penambahan generator set, sedangkan PLTS Off-Grid disimulasikan dengan variasi jenis baterai Lead Acid dan Lithium Ion. Hasil simulasi HOMER dan analisis menunjukkan bahwa penambahan generator set pada sistem PLTS On-Grid optimal menghasilkan NPC yang lebih tinggi dibandingkan dengan sistem tanpa generator set. Kemudian, penggunaan baterai jenis Lithium Ion pada sistem PLTS Off-Grid optimal menghasilkan NPC yang lebih rendah dibandingkan dengan baterai jenis Lead Acid. Dengan demikian, PLTS On-Grid tanpa generator set merupakan konfigurasi paling optimal berdasarkan NPC dan layak untuk diimplementasikan berdasarkan NPV, IRR, dan Payback Period.

The demand for energy, especially electrical energy, in Indonesia is increasing and has become an integral part of the needs of society and the industrial sector. However, the availability of fossil fuels used to generate electricity is increasingly limited, as well as the pollution generated by the conversion process of these fossil fuels. Indonesia has a solar energy potential of 207.8 GWp. However, this potential has not been optimally utilized. Therefore, this potential can be optimized by installing rooftop solar power plants (PLTS) on buildings with high electricity consumption. The MRPQ building of the University of Indonesia with relatively high electricity consumption was used as the study site. The research aims to determine the most optimal configuration and scheme based on Net Present Cost (NPC) and several economic parameters such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period. In HOMER, simulations were performed with On-Grid and Off-Grid configurations. On-Grid PLTS is simulated with variations in the addition of generator sets, while Off-Grid PLTS is simulated with variations in the types of Lead Acid and Lithium Ion batteries. HOMER simulation results and analysis show that the addition of a generator set to the optimal On-Grid PLTS system results in a higher NPC compared to the system without a generator set. Then, the use of Lithium Ion batteries in the optimal Off-Grid PLTS system results in a lower NPC compared to Lead Acid batteries. In summary, On-Grid PLTS without a generator set is the most optimal configuration based on NPC and feasible to implement based on NPV, IRR, and Payback Period.
