The Group has established a complete energy management system, implemented standardized and systematic energy conservation supervision and management, and in accordance with the provisions of the Energy Conservation Law of the People's Republic of China, supports the promotion of effective management of workshop energy conservation and improvement of energy utilization efficiency, and promotes comprehensive economic and social development. Coordinated and sustainable development.

The Group continues to improve its energy management methods and management tools, and gradually promotes intelligent energy-saving management and automated energy management systems. It has now built three sets of energy management centers with intelligent management and analysis functions. Subsidiaries with large energy consumption have basically realized the self-collection and transmission functions of energy data. The energy progression curve formed in real time can monitor the quality parameters (temperature, pressure and flow) of various power systems, remotely adjust and effectively manage the opening and use of workshop equipment, thereby improving the operating efficiency of the power system.

During the reporting period, the main types of energy used by the Group in production and experimentation were purchased steam, natural gas and electricity. Some of our equipment and construction machinery use a small amount of diesel, and our own vehicle auxiliary parts use gasoline.
