The Analysis and Planning for Electricity Cost Reduction in Industry A Case Study of Trang Cannery Company Limited

Abstract

This research presents an analysis to develop a plan to reduce electrical energy costs at Trang Cannery Co., Ltd. from 2022 to 2024. The objectives are to identify trends in energy consumption over the past three years, examine the relationship between production and electricity usage, and propose strategies to improve energy efficiency. Analysis reveals key trends in electricity consumption and its correlation with production volume. An analysis revealed that production efficiency in 2022 is higher than in 2023 and 2024. A consistent decline in efficiency is observed over the two-year period, as evidenced by the increasing electricity consumption per unit of output. This trend is primarily attributed to an imbalance between production capacity and machine size, as well as the lack of preventive maintenance (PM). Furthermore, this study proposes guidelines for measuring electricity consumption, which accounts for 82% of total plant operating costs. These guidelines aim to facilitate data collection in the industrial sector for production cost analysis, thereby enhancing competitiveness. Implementation of these measures is projected to result in a reduction of production costs by no less than 10%.
