The main measures corresponding to power rationing are:
1. Inform the major customers to control and reduce the power load by themselves.
2. The power load management system is adopted to release the terminal power load index, and local control is implemented to limit the power load.
3. The central power load management system is used to directly operate the shunt switch or main switch connected to the terminal to limit the power load.
The reasons for power rationing are as follows:
1. In the early stage, carbon neutralization limited production, and there was exercise-based carbon reduction. Many places are across the board, leading to the closure of coal mines and thermal power plants. Due to the large electricity consumption in summer, the short-term failure of new energy power generation, insufficient power supply, and the shortage of coal in winter. This is the main logic of power restriction.
2. Control the production capacity. In 2020 and 20021year, many orders from Southeast Asia and South Asia were transferred to China because of the epidemic in China. This is certainly a good thing for China's foreign trade enterprises in the short term, but due to the skyrocketing prices of raw materials and shipping, there is a strange phenomenon that the more orders, the greater the losses. The reason behind this is that the United States releases unlimited water, and raw material exporting countries raise prices indefinitely, and all the burdens are borne by intermediate manufacturers. China also discussed these issues with the United States, but the United States did not listen. Therefore, China limited its production capacity, and when it was short of electricity, it was used where it should be used. This forced the United States to negotiate with upstream resource countries. Because limiting production will inevitably lead to a sharp rise in the price of export commodities, and this increase will be borne by American consumers, thus aggravating domestic inflation in the United States, which is what the United States is most afraid of at present, because it does not want to raise interest rates in advance.
3. Prevent overcapacity. China's houses, roads, airports and high-speed trains are almost finished. Therefore, the production capacity was controlled from 20 16, but due to the epidemic in 2020, some industries had overcapacity. Therefore, the national power cut is also to prevent overcapacity in advance.
Dual control of energy consumption will become the normal state in the future. China has promised the international community that by 2030 and 2060, the peak of carbon dioxide emissions will be carbon neutral. The goal of carbon neutrality will become an important economic variable for a long time. Enterprises with high energy consumption must constantly improve their technical level, reduce energy consumption and avoid the influence of dual control of energy consumption.
