The continuous high temperature and drought since July have led to a more severe situation of power supply guarantee in Sichuan this summer than in previous years. According to Sichuan Daily, on August 15, the power supply and dispatching meeting was held again in Sichuan. It is estimated that the maximum power load of the province will increase by 25% over the same period last year, and the situation of power supply and maintenance is very serious. The power supply and demand situation in Sichuan has changed from the “shortage” of power during the peak period in July to the “double shortage” of power and electricity throughout the day. The current situation has prompted the province to decide to implement the emergency notice on expanding the scope of implementation of power supply for industrial enterprises to the people, and to stop all industrial power users (including white list key guarantee enterprises) in the orderly power consumption scheme of Sichuan power grid from 00:00 on August 15 to 24:00 on August 20 to “power supply for the people”< Br > < div class = "height" > < / div > the five pillar industries in Sichuan include electronic information, equipment manufacturing, food and beverage, advanced materials and energy and chemical industry. Power limitation inevitably makes the production plans of relevant enterprises face adjustment. As of August 16, according to incomplete news statistics, more than 20 listed companies have responded to the impact of power rationing in Sichuan< Br > < div class = "height" > < / div > among them, Sichuan, as an important town of photovoltaic manufacturing industry, is one of the main production areas of polysilicon materials in the upstream of photovoltaic. Since last year, the price of polysilicon has soared from about 80000 yuan per ton to 300000 yuan recently, and the price rise of the industrial chain has continued to put pressure on the downstream. The news of power cut-off and restriction has caused panic in the industry again: silicon materials are already in short supply. Will the cut-off of production push up the price again? According to the news, the overall impact is limited< Br > < div class = "height" > < / div > many people will ask questions about the power shortage in Sichuan. In our impression, Sichuan is rich in water resources and has many giant hydropower stations. Why is there a power shortage in summer in a large hydropower province with the largest installed capacity and power generation in China< br>
