Lomanis Fuel Terminal distributes fuel through four pipeline routes using electric transfer pumps, with monthly electricity bills exceeding IDR 1 billion. This study analyzes pump operations, energy consumption, Peak Load Time (WBP) and Off-Peak Load Time (LWBP) costs, and potential savings from rescheduling without changing distributed volume. A quantitative descriptive method used 2025 PLN billing and Batch Program data with daily-resolution idle-slot simulation. Annual consumption totaled 14,781,944 kWh, costing IDR 16,283,735,609; pumps consumed 99.46%. WBP represented 12.7% of energy but 17.9% of costs, with tariffs approximately 50% higher than LWBP. Simulation indicated that 1,408.0 of 5,379.5 WBP operating hours (26.2%) could shift to LWBP while maintaining total operating hours and distributing 7,641,963 KL, potentially saving IDR 254,634,421 annually (1.56%) without capital expenditure. Separately, actual before–after bills showed reductions of 34.69% in WBP consumption and 11.77% in electricity costs, while cost per litre decreased from IDR 2.46 to IDR 2.08 despite a 4.91% volume increase. These changes cannot be attributed entirely to rescheduling because total energy consumption and monthly conditions also varied. CY-2, accounting for an estimated 43.12% of pump energy, is recommended as a conditional implementation priority, subject to receiving-terminal stock validation.
