การลดการใช้พลังงานไฟฟ้าในฐานสนับสนุนการพัฒนาปิโตรเลียม จังหวัดสงขลา

Abstract

This research is to study employees' behavior on electricity usage as to achieve reduction in electricity usage and cost. The representative sample data was collected from 155 employees at the Petroleum Development Support Base at Songkhla province. 3E principle consisting of Engineering, Education and Enforcement is adopted for this study as a technical and behavioral improvement framework in integration with the application of QC Story method. The statistical theories and calculation methods used are Percentage, Mean, Standard Deviation, t-test Value, F-test, One-Way Analysis of Variance (ANOVA), Least Significant Difference (LSD), and Pearson's Correlation Coefficient Analysis. Technically, there were replacements of all 117 lamps, e.g., 66 lamps of the street light, 31 lamps of the flood light and 20 lamps of the high mast light. The investment cost is 1,823,323.72 baht and the payback period is 4 years. Through the behavioral analysis, three projects have been implemented to objectively suit all employees' behavior, focusing on the target group from this study, i.e., electricity saving project, promoting electricity saving news and training program on attitude change towards electricity saving. After 4 months follow-up, the cost of electricity usage is reduced by 14.86 percent. The recommendation for further study is to expand this saving model to other areas such as PTTEP Petroleum Development Support Base at Ranong province, PTTEP Lankrabue Production Station S1 Project at Phitsanulok province and Sinphuhorm Natural Gas Field Project at Udonthani.
