Case Study on Energy Consumption and Electrical Systems at an Integrated Industrial Oil and Gas Terminal

Abstract

The integrated oil and gas terminal is one of the facilities that has a considerable consumption of electrical energy because it supports the process of receiving, storing, and distributing fuel oil (BBM). Most of the energy consumption in the terminals comes from production equipment, specifically distribution pumps that operate continuously. However, there are still terminals that do not have a separation of energy use between production facilities and supporting facilities, making it difficult to evaluate energy efficiency. This study aims to analyze energy consumption patterns and electrical systems in integrated oil and gas terminals. This study uses a case study method with a quantitative descriptive approach. Research data was collected through observation, energy consumption measurement, documentation of operational data and electricity usage, and review of company documents. The results showed that energy consumption in integrated terminals was dominated by production facilities (67%), with production pumps as the main Significant Energy Use (SEU). The electricity system is supplied by PLN and supported by two generator units as a backup resource. The Energy Consumption Intensity (IKE) value of production facilities of 0.0019 GJ/KL/year is in the top 25% category, while supporting facilities of 1.05 GJ/m²/year are in the bottom 25% category. The basic analysis yielded a regression equation of y = -19.59x + 927861 with R² = 0.7535, and identified potential energy savings of 33.90% or 117,148 kWh per year through improved production pump efficiency and the implementation of rooftop solar photovoltaic (PV) panels. These findings show that energy audits are effective in identifying conservation opportunities and improving energy efficiency at integrated oil and gas terminals.
