Abstract

This study offers a thorough financial and risk analysis of a Reserve Margin Bergerak power plant system installed on Landing Craft Tank (LCT) platforms, aimed at improving energy security in Indonesia's remote and archipelagic areas. The total capital expenditure (CAPEX), which is IDR 77.74 billion including taxes, mainly covers engine generators and associated electrical infrastructure. The project's economic viability is assessed using Net Present Value (NPV) and Internal Rate of Return (IRR) under a fixed tariff structure, with a minimum IRR threshold of 8.24%. Sensitivity tests show that the project's success is highly affected by changes in CAPEX but less influenced by operational expenditure (OPEX) variations. A 10% increase in CAPEX drops the IRR to the viability limit, while a 30% cost reduction greatly improves returns. Changes in operational costs have little effect on IRR but slightly boost NPV. Following ISO 31000:2018 standards, risk analysis highlights critical operational risks including design mismatches, tariff inefficiencies, and low LCT utilisation all of which can be addressed through targeted technical reviews, tariff reforms, and deployment strategies. These results emphasise the importance of controlling investment costs and implementing structured risk management to ensure the long-term viability and financial appeal of mobile energy projects.
