Photovoltaic cells have long been regarded as one of the best new energy products to replace existing fossil energy, and polysilicon is the most upstream raw material for photovoltaic cells. However, a large amount of coal-electric power is consumed in the manufacturing process of polysilicon. If there is a large demand for coal power in the upstream manufacturing of photovoltaic products, then the saying that “the photovoltaic industry is clean energy†may also be discounted. "First Financial Daily" was informed that Jiangxi LDK Solar High-Tech Co., Ltd. (hereinafter referred to as "Savi") has been receiving government support in recent years, especially in terms of electricity. This phenomenon is not uncommon in the polysilicon industry. Saiwei enjoys preferential electricity prices The company's headquarters is located in Xinyu, Jiangxi, and is involved in the entire industrial chain of polysilicon, silicon wafers, batteries and components. There are not many similar companies in the photovoltaic industry. At present, the company employs more than 20,000 people and has manufacturing bases in Xinyu, Nanchang, Suzhou and Hefei. In Xinyu, whether it is a government official, an ordinary citizen, a taxi driver or a local industrial and commercial staff, there are almost no ones in the two companies of Saiwei and Xinyu Steel. Local government support for Saiwei is also rare. At the beginning, Saiwei was a company that produces and sells silicon wafers. In 2010, the company's core product wafer sales reached 2.159G watts, and the battery chips and components were around 330M watts. The company's wafers achieved sales revenue of 11.33 billion yuan, a year-on-year increase. 60.5%. After the establishment of "Jiangxi Saiwei LDK Solar Polysilicon Co., Ltd." in 2007, the whole line advanced into the polysilicon industry. With the launch of the second annual production line of 5,000 tons of LDK photovoltaic silicon in August 2010, the current production capacity of the company's polysilicon is about 11,000 tons. Our reporter learned from people familiar with the matter that Saiwei did receive government subsidies for electricity prices. Saiwei once enjoyed a preferential price of around 0.32 yuan / kWh, while the normal industrial electricity price of Xinyu at that time was about 0.5 yuan / kWh. According to a 2008 local government document, Jiangxi Electric Power Company and other units have also implemented a preferential price of around 0.48 yuan / kWh for Saiwei. In fact, there is a difference between the preferential electricity price paid by Saiwei and the normal industrial electricity price, which is currently 0.12 yuan/kWh, and this difference is basically paid by the government. The reporter learned that the management committee of the Xinyu Economic Development Zone, where Savi was located, entrusted a construction investment company to subsidize. However, at present, the government subsidizes the electricity subsidy, and there is no public data to check. However, this electricity subsidy is at least 100 million yuan per year. It is understood that the current preferential price of 0.48 yuan / kWh is still being implemented, and there is no exact statement when it will be suspended. A person from the Saiwei Xinyu High-tech Industrial Development Zone said that if there are enterprises that are willing to enter the area, the electricity price for industrial electricity will be about 0.58 yuan / kWh to 0.61 yuan / kWh. The person said that it was not clear about the preferential electricity price of Saiwei. According to a management of a local power company, the total annual power consumption of bases including SV's polysilicon and silicon wafers is more than one billion kWh. Polysilicon consumes a lot of electricity. "Polysilicon actually consumes a lot of electricity. In order to attract more PV companies to settle in and boost employment and raise local fiscal revenue, some polysilicon companies have indeed provided electricity prices including land prices and land. A preferential policy." A senior PV company told this reporter. For example, he said that when a domestic first-class polysilicon enterprise manufactures one kilogram of polysilicon, it needs about 80 kilowatt-hours of electricity, and its electricity cost is about 0.7 yuan/kWh. According to the current cost of 1 kilogram of polysilicon of 30 US dollars, in fact, electricity costs account for about one-third of the total manufacturing cost of polysilicon. In addition, according to the above electricity price calculation, the power consumption of 10,000 tons of polysilicon is 800 million kWh. However, such polysilicon enterprises are established in the east of China, and the local government rarely gives electricity price concessions. In other words, even for a better 10,000-ton polysilicon project, the annual electricity bill will be as high as 560 million yuan. He also said that in Sichuan, electricity prices in some areas are about 0.45 yuan / kWh, but its power consumption is up to 180 kWh per kilogram, so their electricity costs are 42% more than low-cost polysilicon enterprises. Therefore, the total manufacturing cost of its polysilicon is high. Therefore, if a regional government can control and lower the price of electricity, polysilicon enterprises need to increase their competitiveness by expanding production scale, selecting new technologies and reducing energy consumption. On the contrary, under the government's subsidies, enterprises are not only difficult to control the power consumption, but also bring disadvantages to the cost reduction of the entire photovoltaic industry. If the cost of polysilicon products cannot be rapidly reduced, it is unrealistic to rely solely on silicon wafers, batteries, components, etc. to reduce costs. In addition, many foreign polysilicon companies have decades of experience in polysilicon production and mature technology. Once these overseas companies transfer their production bases from overseas to the western regions of China where electricity prices are relatively cheap, most of China's polysilicon enterprises will not lose. .
