Abstract
Keandalan pasokan listrik pada fasilitas hulu migas terpencil seperti West Pangkah sangat krusial untuk menjaga kontinuitas produksi. Perubahan status dari unmanned menjadi manned facility telah meningkatkan beban listrik mendekati kapasitas maksimum Diesel Engine Generator (DEG) eksisting, sehingga meningkatkan risiko overload, biaya bahan bakar, dan emisi. Penelitian ini bertujuan menganalisis performa tekno-ekonomi dan reduksi emisi dari integrasi microgrid hibrida Diesel–Solar PV–BESS sebagai solusi dekarbonisasi dan optimasi energi di West Pangkah. Metodologi penelitian dilakukan menggunakan HOMER Pro dengan memodelkan data beban listrik aktual untuk mensimulasikan tiga skenario (Baseline, Eksisting, dan Konfigurasi Optimal) dalam 20 tahun siklus hidup proyek. Hasil simulasi menunjukkan bahwa Konfigurasi Optimal dengan penambahan kapasitas Solar PV sebesar 95 kW menjadi konfigurasi terbaik yang mampu meningkatkan bauran energi terbarukan hingga 28,96%. Integrasi ini memangkas konsumsi solar sebesar 37,43% dan mereduksi emisi CO2 menjadi 92.508 kg/tahun. Skenario ini menghasilkan Total Net Present Cost (NPC) terendah sebesar IDR 7,88 miliar dan Levelized Cost of Energy (LCOE) 6.359,56 IDR/kWh. Penelitian ini membuktikan bahwa perluasan kapasitas modul surya mampu memitigasi fluktuasi biaya bahan bakar sekaligus mendukung target dekarbonisasi.

The reliability of the power supply in remote oil and gas facilities, such as West Pangkah, is critical to maintaining production continuity. Transitioning from an unmanned to a manned facility has increased the electrical load close to the maximum capacity of the existing Diesel Engine Generator (DEG), thereby triggering overload risks, high fuel operating costs, and increased emissions. This study aims to analyze the techno-economic and emission reduction performance of integrating a hybrid Diesel–Solar PV–BESS microgrid as a decarbonization and energy optimization solution in West Pangkah. The research methodology was conducted by modeling real field electrical load data using HOMER Pro to simulate three scenarios (Baseline, Existing, and Optimal Configuration) over a 20-year project lifecycle. The simulation results demonstrate that the Optimal Configuration with an additional Solar PV capacity of 95 kW is the superior setup, capable of increasing the renewable energy mix up to 28,96%. This integration slashes diesel consumption by 37,43% and reduces CO2 emissions to 92.508 kg/year. Furthermore, this scenario generates the lowest Total Net Present Cost (NPC) of IDR 7,88 billion and a Levelized Cost of Energy (LCOE) of 6.359,56 IDR/kWh. This study proves that expanding solar module capacity effectively mitigates fuel cost volatility while supporting corporate decarbonization targets.
