Abstract

Pembangkit Listrik Tenaga Surya (PLTS) merupakan salah satu jenis energi baru dan terbarukan (EBT) yang memanfaatkan energi dari matahari. Indonesia memiliki potensi besar untuk pengembangan energi surya, dengan potensi radiasi matahari rata-rata mencapai 4,8 kWh/m² per hari. Namun, hingga saat ini, pemanfaatannya masih tergolong rendah. Berdasarkan data Kementerian ESDM, capaian EBT pada tahun 2024 hanya sebesar 14,7% dari target 19,5%, sementara target yang ditetapkan pemerintah untuk tahun 2025 adalah sebesar 23%. Selain itu, realisasi kapasitas terpasang PLTS pada tahun 2023 hanya mencapai 4,3% dari total kapasitas energi terbarukan (meliputi bayu, surya, bioenergi, panas bumi, air, gas, dan batu bara). Sehubungan dengan hal tersebut, dalam rangka mensukseskan program pemerintah, PT Pertamina (Persero) beserta anak perusahaannya tengah melakukan perencanaan pengembangan PLTS atap pada fasilitas pendukung penyaluran minyak dan gas bumi, salah satunya di
PT Pertamina Gas (Pertagas). Berdasarkan simulasi yang dilakukan menggunakan perangkat lunak Helioscope, rencana pengembangan PLTS atap (on-grid) di beberapa lokasi PT Pertamina Gas dapat memproduksi energi listrik hingga 46.271,35 kWh per tahun dengan kapasitas terpasang mencapai 37,88 kWp. Sistem PLTS ini menunjukkan nilai performance ratio yang berkisar antara 70–80%. Dari hasil perhitungan keekonomian dan analisis kelayakan, proyek ini dinyatakan layak karena menghasilkan parameter finansial sebagai berikut: Net Present Value (NPV) > 0, Internal Rate of Return (IRR) > Discount Rate, Discounted Payback Period (DPP) < umur proyek, Profitability Index (PI) > 1, dan Benefit-Cost Ratio (BCR) > 1. Nilai IRR dari perhitungan berkisar antara 15–19% dengan rata-rata Discounted Payback Period mencapai ±10,19 tahun. Selain itu, analisis keekonomian menunjukkan potensi penghematan tagihan listrik sebesar Rp 7.438.342,21 per bulan atau ekuivalen dengan Rp 89.260.106,58 per tahun, yang setara dengan efisiensi sebesar 16,5% dari tarif listrik PLN eksisting. Selisih tarif Levelized Cost of Energy (LCOE) PLTS dibandingkan dengan tarif PLN rata-rata adalah Rp. 255,49/kWh.

Solar Power Plants (PLTS) are one type of new and renewable energy (EBT) that utilizes energy from the sun. Indonesia has great potential for the development of solar energy, with an average solar radiation potential reaching
4.8 kWh/m² per day. However, until now, its utilization is still relatively low. Based on data from the Ministry of Energy and Mineral Resources, the achievement of EBT in 2024 was only 14.7% from target 19,5%, while the target set by the government for 2025 was 23%. In addition, the realization of the installed capacity of PLTS in 2023 only reached 4,3% of the total renewable energy capacity (including wind, solar, bioenergy, geothermal, water, gas, and coal). In connection with this, in order to make the government program a success,
PT Pertamina (Persero) and its subsidiaries is currently planning the development of rooftop PLTS at supporting facilities for the distribution of oil and natural gas, one of which is at PT Pertamina Gas (Pertagas). Based on simulations carried out using Helioscope software, the plan to develop rooftop PLTS (on-grid) at several locations of PT Pertamina Gas can produce up to 46,271.35 kWh of electricity per year with an installed capacity of 37.88 kWp. This PLTS system shows a performance ratio value ranging from 70–80%. From the results of economic calculations and feasibility analysis, this project is declared feasible because it produces the following financial parameters: Net Present Value (NPV) > 0, Internal Rate of Return (IRR) > Discount Rate, Discounted Payback Period (DPP) < project age, Profitability Index (PI) > 1, and Benefit-Cost Ratio (BCR) > 1. The IRR value from the calculation ranges from 15–19% with an average Discounted Payback Period reaching ±10.19 years. In addition, the economic analysis shows the potential for electricity bill savings of IDR 7,438,342.21 per month or equivalent to
IDR 89,260,106.58 per year, which is equivalent to an efficiency of 16.5% of the existing PLN electricity tariff. The difference in the Levelized Cost of Energy (LCOE) tariff of PLTS compared to the average PLN tariff is Rp. 255.49/kWh.
