Abstract

Indonesia memiliki potensi besar dalam pengembangan energi terbarukan, khususnya tenaga angin lepas pantai, namun hingga saat ini belum ada proyek Floating Offshore Wind Turbine (FOWT) yang dikembangkan secara komersial. Teknologi FOWT dengan struktur semi-submersible menawarkan solusi energi bersih yang dapat diimplementasikan di perairan dalam seperti di wilayah Arafura. Penelitian ini bertujuan untuk mengevaluasi kelayakan finansial proyek FOWT di perairan Arafura dengan pendekatan estimasi investasi (CAPEX dan OPEX), proyeksi pendapatan energi tahunan, serta analisis arus kas menggunakan indikator Net Present Value (NPV), Profitability Index (PI), dan Payback Period. Simulasi dilakukan berdasarkan empat skenario harga jual listrik dan struktur OPEX, yaitu: benchmark global dengan OPEX persentase pendapatan, benchmark global dengan OPEX tetap, BPP PLN dengan OPEX persentase pendapatan, dan BPP PLN dengan OPEX tetap. Hasil penelitian menunjukkan bahwa hanya skenario 1 dan 2 yang layak secara ekonomi, dengan NPV positif dan PI > 1. Skenario 2 menghasilkan NPV tertinggi sebesar Rp 410,68 miliar dan payback period 6,2 tahun, namun dengan asumsi OPEX tetap yang kurang realistis. Sementara itu, skenario 1 dipilih sebagai skenario paling representatif dengan NPV Rp 369,23 miliar, PI sebesar 1,51, dan payback period 6,3 tahun. Kedua skenario berbasis harga domestik (BPP PLN) menunjukkan ketidaklayakan finansial dengan nilai NPV negatif. Dengan demikian, studi ini menunjukkan bahwa proyek FOWT di Indonesia layak secara ekonomi bila didukung oleh kebijakan harga listrik yang kompetitif dan perencanaan biaya yang fleksibel.

Indonesia has significant potential in the development of renewable energy, particularly offshore wind power. However, to date, no Floating Offshore Wind Turbine (FOWT) projects have been commercially developed. The FOWT technology with a semi-submersible structure offers a clean energy solution that can be implemented in deep waters, such as the Arafura region. This study aims to evaluate the financial feasibility of a FOWT project in Arafura waters by estimating investment costs (CAPEX and OPEX), projecting annual energy revenues, and conducting cash flow analysis using financial indicators such as Net Present Value (NPV), Profitability Index (PI), and Payback Period. Simulations are conducted based on four scenarios of electricity selling prices and OPEX structures: global benchmark with revenue-based OPEX, global benchmark with fixed OPEX, PLN’s Basic Production Cost (BPP) with revenue-based OPEX, and BPP with fixed OPEX. The results show that only Scenario 1 and Scenario 2 are economically viable, with positive NPVs and PI values greater than 1. Scenario 2 yields the highest NPV of IDR 410.68 billion and a payback period of 6.2 years, although it assumes a fixed OPEX, which is considered less realistic. Meanwhile, Scenario 1 is selected as the most representative scenario, with an NPV of IDR 369.23 billion, a PI of 1.51, and a payback period of 6.3 years. Both scenarios based on domestic electricity prices (PLN BPP) indicate financial infeasibility with negative NPV values. Therefore, this study concludes that FOWT projects in Indonesia can be economically feasible if supported by competitive electricity pricing policies and flexible cost planning.
