According to China Voice "Yangguang News", due to the rising price of coal in January, the key contract coal is less than 70%. The five major power generation groups have jointly reported to the State-owned Assets Supervision and Administration Commission, the National Development and Reform Commission and the State Council, reflecting the rise in coal prices. The situation and the operating conditions of power generation companies have promoted the introduction of coal-electricity linkage policies. At the end of last year, in order to prevent coal price inflation, the State Council No. 40 Document, Development and Reform Commission No. 386 and No. 2880 have clearly stated that “the annual key thermal coal contract price in 2011 will remain unchanged in the previous year, and no price increase in any formâ€. However, according to informed sources, at the end of February, the State Council’s senior officials convened the main person in charge of the power generation company to listen to the work report. The five major groups responded that despite the central government’s policy, in fact, “the key contract quantity of coal, fuel calorific value, intermediary agent, market Make a fuss about coal price and key contract redemption rate, adopt a flexible approach, and negatively treat national policies or disguise price increases. According to the materials compiled by the five major power generation groups, most of the key coal-fired contracts in 2011 have been signed at unspent prices, but each The unit price of standard coal in January of the Dayan Power Group increased to varying degrees. According to the statistics of the five major power generation groups, in recent years, due to the sharp rise in the price of thermal coal, the fuel cost of thermal power companies has accounted for more than 70% of the cost of power generation. Taking Huaneng as an example, since 2004, the price of coal in the group has increased by more than 130%, while the price of electricity has increased by only 29%, which is far from offsetting the deficit caused by the rise in coal prices. The price gap has reached 8.6 points/kWh, even considering power generation companies. Digested by 30%, the gap still reached 4 points / kWh, and the annual economic impact was over 20 billion yuan. In January of this year, the thermal power sector of the five major power generation groups suffered a total loss, and the loss of power plants rose to 60%. In January, the purchase price of standard coal increased by 31.4 yuan/ton, up by 75.5 yuan/ton. A senior executive of a power group said that according to current estimates, according to the current coal price, the five major power generation groups will lose money at the end of the year. "The total loss will be at least 35 billion yuan." Therefore, the top priority of the five major power generation groups is to "actively connect with coal enterprises and railway departments, and strive to increase the key contract redemption rate, and strive for a cash rate of not less than 80%." The head of a fuel company said in an interview with this newspaper. According to informed sources, at present, the five major power generation groups have expanded their supply channels to Indonesia, Australia and Russia, and their import channels have expanded to Colombia, the United States and South Africa. According to customs statistics, China's net import of coal in 2010 was 145.8 million tons, an increase of 29% year-on-year. The main reason for the large amount of imported coal is still due to price advantage. The current coal freight rate from Baotou to Qinhuangdao Port is US$50/ton, while the freight rate from Colombia to Qinhuangdao Port is US$20/ton. "And, generally transported to coastal power plants, compared with the thermal coal in Inner Mongolia, Shaanxi and other places, has an absolute price advantage." In this regard, the China Electricity Council's opinion is that the coal-electricity linkage mechanism should be improved as soon as possible to shorten the price of electricity. The linkage lag period, synchronously increase the on-grid price and sales price, and increase the electricity price by 3 cents per kWh to compensate for the gap in the coal-electricity linkage lag. For some coal enterprises to reduce the calorific value, reduce the amount of key contracts, increase the market price of coal and other disguised price increases, several major power generation groups have jointly reported to the government and received support and intervention from the National Development and Reform Commission.
