The Energy Management System (EMS) records, monitors, and optimizes energy usage through smart meters. Yih Shan shall continue to improve energy efficiency, reduce carbon emissions, and ensure the reliability and stability of the energy supply. 

The main functions of the EMS include: 

1. Monitoring and Data Collection: Device data about aspects such as power, voltage, and energy usage, are collected in real-time for analysis and optimization. 
2. Analysis and Evaluation: Energy data is analyzed to identify areas for improvement in energy efficiency. 
3. Reporting and Compliance: Reports on energy consumption are generated to meet regulatory requirements and internal management needs. 

Through the effective implementation of EMS, Yih Shan has significantly reduced energy costs and improved sustainability performance, earning both economic and environmental benefits. 

Yih Shan employs the energy management system to rapidly analyze data and make informed decisions, enhancing energy efficiency and minimizing energy waste.
