In the year 2023, an investment of 19.288 million NT dollars was made in energy-saving equipment, resulting in an overall energy-saving rate of 47.4%. Additionally, subsidies were obtained from the Ministry of Economic Affairs’ Energy Bureau under the “Energy Efficiency Performance Guarantee Project Demonstration and Promotion Subsidy Plan” for the year 2022.
The energy usage primarily involved electricity. Energy-saving objectives were planned around controlling the temperature and humidity in the production environment and optimizing electricity usage in the manufacturing process. Improvements were focused on enhancing environmental control systems and energy-consuming manufacturing equipment.
Specific improvements were made to the operation control of air conditioning units and the efficiency enhancement of the chilled water main unit. The outcomes after improvement included an energy-saving rate of 47.4%, a reduction equivalent to 130.4kLOE/year in oil consumption, a decrease of 684.4 tons/year in tCO2 emissions, and a saving of 1,363,638 kWh/year in electricity consumption.
