Efficient motor promotion is not recommended to the NPC deputies.
"In recent years, the state has increased the promotion of high-efficiency motors, and has introduced many policies, including financial subsidies, but the effect is not obvious. At present, the proportion of high-efficiency motors in domestic stock is only about 8%. On March 10, Huang Daifang, deputy chairman of the National People's Congress, China Civil Chamber of Commerce and chairman of Taihao Group Co., Ltd., said in an interview that the state should compel enterprises to use high-efficiency motors, reverse the transformation and upgrading of motor production enterprises, and promote supply-side reform.
Huang Daifang introduced that motors are widely used in industrial fields. As the driving devices of various mechanical equipment, such as fans, pumps, compressors, machine tools, conveyor belts, they are the most power-consuming equipment.
According to statistics, in 2015, China has about 2.4 billion kilowatt-hours of motor, and its total power consumption is about 3.5 trillion kilowatt-hours. The total social electricity consumption is 5.55 trillion kilowatt-hours, accounting for 65% of the total social electricity consumption. The total power consumption of motor in the industrial field is 2.9 trillion kilowatt-hours, industrial electricity consumption is 3.93 trillion kilowatt-hours, accounting for 74% of industrial electricity consumption, and industrial electricity consumption accounts for 52% of the total social electricity consumption.
Worldwide, 50% of the global total annual electricity consumption and 60% - 70% of the industrial electricity consumption are consumed in the motor system. The optimal design of the motor system can save 9% - 13% of the country's industrial electricity consumption. The efficiency of high-efficiency motor in developed countries has reached over 91%, the efficiency of ultra-high-efficiency motor in the United States is as high as 93%, and the efficiency of system operation is 10-20% higher than that in China.
For every percentage point increase in motor energy efficiency in the industrial field, about 26 billion kilowatt-hours of electricity can be saved annually. Through energy efficiency improvement, the overall efficiency of motor system can be improved by 5-8 percentage points. It can save 1300-230 billion kilowatt-hours of electricity in a year, equivalent to 2-3 generations of the Three Gorges Power Station.
The promotion of high efficiency motors can be traced back to 2007. In 2008, China listed the energy-saving of motor system as one of the ten national energy-saving projects. In 2009, the application of high-efficiency and ultra-high-efficiency motors was included in Huimin Project. On June 2, 2010, a notice was issued that high-efficiency Motors should be included in the implementation scope of Huimin Project, so that the market promotion of high-efficiency Motors has attracted much attention.
"In recent years, the state has intensified the promotion of high-efficiency motors, formulated motor energy efficiency grade standards according to IEC standards, and issued many policies to support the application and promotion of high-efficiency motors. However, the proportion of high-efficiency motors in domestic stock is only about 8%, and the share of high-efficiency motors is growing slowly." Huang Daifang said that the current social stock of motor is still mainly low efficiency level 3 energy efficiency.
