According to relevant national mandatory energy efficiency standards, implement "Motor Energy Efficiency Improvement Plan (2021-2023)" and "Transformer Energy Efficiency Improvement Plan (2021-2023)", carry out energy-saving monitoring and check equipment for key energy-consuming equipment user companies such as motors, transformers, fans, air compressors, and pumps Account, together with relevant departments to urge enterprises to eliminate inefficient equipment that does not meet the limit value of mandatory energy efficiency standards. This special inspection is carried out in conjunction with other special inspections, and does not declare tasks separately.

2021 special supervision on the implementation of rectification of violating enterprises. for 2021 Enterprises with excessive energy consumption and other enterprises violating energy-saving laws and regulations found in special energy-saving inspections will carry out inspections. For those who fail to make rectifications in accordance with the requirements or are not in place, they will be dealt with in accordance with laws and regulations in conjunction with relevant departments.

my country's high-efficiency motor industry is developing rapidly and promoting the application of carbon reduction results Significantly

my country's motor industry is large. According to statistics, the national industrial motor output in 2020 will be 323 million kilowatts. Motor manufacturing enterprises are mainly distributed in Zhejiang, Jiangsu, Fujian, Shandong, Shanghai, Liaoning, Guangdong and Henan. The number of motor manufacturing enterprises in these eight provinces and cities accounts for about 85% of the total number of motor manufacturing enterprises in my country.

The production and promotion of high-efficiency motors in my country has achieved remarkable results. According to the "White Paper on High-Efficiency Motor Promotion Projects", the output of high-efficiency motors and remanufactured motors in my country increased from 20.04 million kilowatts in 2017 to 105 million kilowatts in 2020, of which the output of high-efficiency motors rose from 19.2 million kilowatts to 102.7 million kilowatts. The number of high-efficiency motor and remanufactured motor manufacturers increased from 355 in 2017 to 1,091 in 2020, accounting for the proportion of motor manufacturers from 13.1% to 40.4%. The high-efficiency motor supply and sales market system is becoming more and more perfect. The number of suppliers and sellers has increased from 380 in 2017 to 1,100 in 2020, and the sales volume in 2020 will reach 94 million kilowatts. The number of companies using high-efficiency motors and remanufactured motors continues to increase, and the number of companies using high-efficiency motors has increased from 201769,300 increased to more than 94,000 in 2020, and the number of companies using remanufactured motors rose from 6,500 to 10,500.

The promotion and application of high-efficiency motors has achieved remarkable results in energy saving and carbon reduction. According to estimates, from 2017 to 2020, the annual power saving of high-efficiency motor promotion will increase from 2.64 billion kWh to 10.7 billion kWh, and the cumulative power saving will be 49.2 billion kWh; the annual reduction of carbon dioxide emissions will rise from 2.07 million tons to 14.9 million tons. A total of more than 30 million tons of carbon dioxide emissions have been reduced.

Our country takes multiple measures to promote high-efficiency motors

my country attaches great importance to the improvement of motor energy efficiency and the promotion of high-efficiency motors. Relevant policies have been detailed and implemented many promotional measures.

In terms of policy guidance, focus on improving the energy efficiency of motors and their systems, and eliminating low-efficiency motors . Guide and urge enterprises to eliminate low-efficiency motors through industrial energy conservation monitoring, motor energy efficiency improvement plans, and the release of the "High Energy Consumption Outdated Electromechanical Equipment (Products) Elimination Catalog". During the "13th Five-Year Plan" period, special inspections were carried out on the production and use of key energy-consuming products such as motors and pumps to improve the energy efficiency of motors. About 150,000 low-efficiency motors were found, and the companies were ordered to rectify within a time limit.

In terms of standard guidance, the motor energy efficiency standard is enforced and the motor energy efficiency label is implemented. In 2020, the mandatory national standard "Energy Efficiency Allowable Values and Energy Efficiency Grades of Electric Motors" (GB 18613-2020) was released, which replaced the "Energy Efficiency Allowable Values and Energy Efficiency Grades of Small and Medium-sized Three-phase Asynchronous Motors" ( GB 1 8 6 1 3 – 2 0 1 2) and "Energy Efficiency Allowable Values and Energy Efficiency Classes for Small Power Motors" (GB 25958-2010). The release and implementation of the standard raised my country's minimum energy efficiency standard IE2 to IE3 level, constraining motor manufacturers to produce motors higher than IE3 level, and further promoted the production of high-efficiency motors and the increase in market share. At the same time, motors for sale are required to be affixed with the latest energy efficiency labels, so that buyers can more clearly understand the efficiency level of the purchased motors.

In terms of publicity and promotion activities, release promotional catalogs, carry out technical training, organize "energy-saving services Enter the enterprise" activities, etc. Through the release of six batches of ""Energy-saving Products Benefiting the People Project" High-efficiency Motor Promotion Catalogue", five batches of "National Industrial Energy-Saving Technology Equipment Catalogue", ten batches of ""Energy Efficiency Star" Product Catalogue", seven batches of "Energy-saving Electromechanical Equipment (Products) Recommended Catalog", recommend high-efficiency motors and energy-saving equipment and products using high-efficiency motors to the society, and guide enterprises to use high-efficiency motors. At the same time, the "Remanufacturing Product Catalog" was released to promote the remanufacturing of low-efficiency motors into high-efficiency motors and improve the level of resource recycling. For motor-related management personnel and energy management personnel of key energy-consuming enterprises, organize multiple training sessions on motor energy-saving technologies. In 2021, the Ministry of Industry and Information Technology will also organize relevant units to hold 34 "energy-saving services into enterprises" activities.

In terms of technical services, organize three batches of industrial energy-saving diagnostic services . From 2019 to the end of 2021, the Ministry of Industry and Information Technology organized third-party service agencies for energy-saving diagnosis to conduct energy-saving diagnosis in 20,000 enterprises, and evaluated the energy efficiency level and actual operation of key electrical equipment such as motors, fans, air compressors, and pumps. To help enterprises identify low-efficiency motors, analyze the potential of high-efficiency motors for promotion and application, and guide enterprises to carry out motor energy conservation.

In terms of financial support, include high-efficiency motors in the scope of implementation of energy-saving products to benefit the people . The Ministry of Finance provides financial subsidies to motor products of different types, grades and powers according to the rated power. The central government allocates subsidy funds to high-efficiency motor manufacturers, and the manufacturers sell them to motor users, water pumps and fans at the subsidized price. Complete equipment manufacturing enterprises. However, starting from March 2017, the purchase of high-efficiency motor products in the catalog of "energy-saving products benefiting the people" will no longer enjoy central financial subsidies. At present, some regions such as Shanghai have also set up special funds to support the promotion of high-efficiency motors.
