Abstract

Studi perbandingan ini mengevaluasi berbagai model distribusi gas alam cair (LNG) untuk menyediakan listrik ke smelter di Halmahera Timur, Indonesia. Studi ini membandingkan penggunaan kapal pengangkut LNG ke fasilitas regasifikasi darat, unit float-ing storage and regasification unit (FSRU), dan shuttle and regasification vessel (SRV). Analisis ini berfokus pada menentukan model distribusi yang optimal, fasilitas yang diperlukan, dan kelayakan ekonomi. Studi ini mempertimbangkan kilang LNG Tangguh sebagai pemasok alternatif karena lokasinya yang berdekatan dengan pabrik peleburan. Proses pemilihan kapal mempertimbangkan biaya investasi dan operasional, termasuk pembelian dan konversi kapal. Model Distribusi 1 memiliki CAPEX sebesar 741.945 miliar rupiah dan OPEX sebesar 2.103 triliun rupiah; Model Distribusi 2 memiliki CAPEX sebesar 719.73 miliar rupiah dan OPEX sebesar 1.731 triliun rupiah; Model Distribusi 3 Skenario A memiliki CAPEX sebesar 1.053 triliun rupiah dan OPEX sebesar 3.026 triliun rupiah; Model Distribusi 3 Skenario B - 1 memiliki CAPEX sebesar 636.29 miliar rupiah dan OPEX sebesar 2.219 triliun rupiah; dan Model Distribusi 3 Skenario B - 2 memiliki CAPEX sebesar 862 miliar rupiah dan OPEX sebesar 1.873 triliun rupiah. Harga jual untuk setiap model distribusi berkisar antara 2.15 USD/MMBTU hingga 3.76 USD/MMBTU. Analisis kelayakan ekonomi menggunakan tingkat diskon yang berasal dari Weighted Average Cost of Capital (WACC) sebesar 12.19% untuk semua model. Perhitungan tarif dilakukan dengan melakukan variasi margin, dimana margin 13% memenuhi kriteria kelayakan ekonomi yaitu IRR>WACC, NPV>0, dan payback period < waktu proyek untuk semua model. Pada margin model Distribusi 1 memiliki tarif sebesar 2.73 USD/MMBTU, IRR sebesar 13.56%, dan NPV sebesar 6.8 juta USD; Model Distribusi 2 memiliki tarif sebesar 2.43 USD/MMBTU, IRR sebesar 14.24%, dan NPV sebesar 4.92 juta USD; Model Distribusi 3 Skenario A memiliki tarif sebesar 3.76 USD/MMBTU, IRR sebesar 13.28%, dan NPV sebesar 3.751 juta USD; Model Distribusi 3 Skenario B - 1 memiliki tarif sebesar 2.67 USD/MMBTU, IRR sebesar 14.19%, dan NPV sebesar 4.12 juta USD; dan Model Distribusi 3 Skenario B - 2 memiliki tarif sebesar 2.86 USD/MMBTU, IRR sebesar 12.37%, dan NPV sebesar 519 ribu USD.

In this comparative study, various liquefied natural gas (LNG) distribution models are evaluated for providing electricity to a smelter in East Halmahera, Indonesia. The use of LNG carriers, onshore regasification facilities, floating storage and regasification units (FSRU), and shuttle and regasification vessel (SRV) is compared. The focus of the analysis is on determining the optimal distribution model, identifying the required facilities, and assessing economic feasibility. The Tangguh LNG plant is considered as an alternative supplier due to its proximity to the smelter. The vessel selection process takes into account investment and operational costs, including vessel purchase and conversion. Model Distribution 1 has a CAPEX of 741.945 billion rupiah and OPEX of 2.103 trillion rupiah; Model Distribution 2 has a CAPEX of 719.73 billion rupiah and OPEX of 1.731 trillion rupiah; Model Distribution 3 Scenario A has a CAPEX of 1.053 trillion rupiah and OPEX of 3.026 trillion rupiah; Model Distribution 3 Scenario B - 1 has a CAPEX of 636.29 billion rupiah and OPEX of 2.219 trillion rupiah; and Model Distribution 3 Scenario B - 2 has a CAPEX of 862 billion rupiah and OPEX of 1.873 trillion rupiah. The sales prices for each distribution model range from 2.15 USD/MMBTU to 3.76 USD/MMBTU. The economic feasibility analysis uses a discount rate derived from the Weighted Average Cost of Capital (WACC) of 12.19% for all models. Tariff calculations are conducted by varying the margin, with a 13% margin meeting the economic feasibility criteria, including IRR > WACC, NPV>0, and payback period < project duration for all models. At a 13% margin, Model Distribution 1 has a tariff of 2.73 USD/MMBTU, IRR of 13.56%, and NPV of 6.8 million USD; Model Distribution 2 has a tariff of 2.43 USD/MMBTU, IRR of 14.24%, and NPV of 4.92 million USD; Model Distribution 3 Scenario A has a tariff of 3.76 USD/MMBTU, IRR of 13.28%, and NPV of 3.751 million USD; Model Distribution 3 Scenario B - 1 has a tariff of 2.67 USD/MMBTU, IRR of 14.19%, and NPV of 4.12 million USD; and Model Distribution 3 Scenario B - 2 has a tariff of 2.86 USD/MMBTU, IRR of 12.37%, and NPV of 519 thousand USD.
