Although the first "electric highway" from Xinjiang to the mainland was opened, the role of the "West-to-East Power Transmission" to the central and eastern regions has not been opened on a large scale, so the effect is limited.
On November 3, the first “electric highway†from Xinjiang to the mainland – the 750 kV network project of Xinjiang and Northwest Power Grid was officially opened. The opening of China’s largest energy “water tap†is to solve the “electricity†that has occurred frequently in recent years. The wasteland offers possibilities. However, due to the delay in the large-scale opening of China’s “West-to-East Power Transmission†to the central and eastern regions, only a small part of Xinjiang’s surplus power is used in the Northwest Power Grid through this “highwayâ€, but it is still unable to be large-scale. Lost to the central and eastern regions. According to industry insiders, a large amount of surplus electricity is difficult to release in the northwest, which not only greatly restricts the role of this "electric highway", but also has many negative effects on China's economy.
Poor power channels cause many negative effects
The large amount of surplus power in the northwest has created a strong “force†effect on the surge of high-energy-consuming industries. For such a situation, the northwestern provincial governments and the power sector are well aware, but out of the economic development of the provinces. The consideration is that it is difficult to change the development trend of this industry.
The passage of “West-to-East Power Transmission†in the northwest has not been opened on a large scale, which has brought many negative effects to the development of China’s economy.
First, it is impossible to solve the problem of “power shortage†fundamentally. Yu Xinqiang, general manager of Northwest Power Grid Co., Ltd. said that the current power shortage in China is actually not a lack of generator sets, but a lack of coal. "Lack of coal --- shutdown --- pull the brakes --- power cut --- then increase the unit --- more lack of coal", in recent years has become a part of Central China, East China in the energy development can not get out A strange circle. To get out of this strange circle, only the construction of the power transmission channel will be increased.
Second, a large amount of surplus electricity was “would†in the northwest, which greatly stimulated the excessive development of local high-energy-consuming industries. For example, in Qinghai from 2004 to 2006, electricity consumption increased by 32.6%, 10.34%, and 19.96%, respectively. Ningxia's annual electricity consumption increased by 30.3%, 14.96%, and 29.14%, respectively, while the GDP of the two provinces increased during the same period. The speed is much lower than the increase in electricity consumption. The proportion of electricity consumption in high-energy-consuming industries in the two provinces has also been increasing. The proportion of electricity consumption in high-energy-consuming industries in Qinghai from 2004 to 2006 was 76.43%, 77.6%, and 78.66%, respectively. The proportion of electricity consumption in high-energy-consuming industries in Ningxia was 65.47. %, 67.29%, and 69.46%, the industrial energy consumption of the two provinces tends to be high and energy-consuming. This highly energy-intensive industrial development trend has directly led to a surprisingly high energy consumption in the northwest. For example, Ningxia's GDP per unit of energy consumption is the highest in the country.
The large amount of surplus power in the northwest has created a strong “force†effect on the surge of high-energy-consuming industries. For such a situation, the northwestern provincial governments and the power sector are well aware, but out of the economic development of the provinces. The consideration is that it is difficult to change the development trend of this industry. In fact, high-energy-consuming industries have become the leading industries in many regions of the Northwest, and at the same time they are the largest customers of electricity consumption. The dependence of the two sides is quite high. “Selling coal-selling electricity-selling high-energy-consuming products†has become the northwestern Three important steps in the continuous upgrading of resource development strategies in less regions. According to forecasts, from 2008 to 2020, only Qinghai Province will have a surplus of 2.9 to 9.07 million kilowatts of electricity, with a surplus of between 8 and 31.5 billion kWh. If the problem of northwest power transmission cannot be solved well, the situation that surplus power will “force†the surge in high-energy-consuming enterprises will further intensify.
Third, the poor transmission of the power transmission channel makes Xinjiang unable to play its biggest economic advantage--energy advantage, and the accelerated development of Xinjiang's economy is greatly restricted. The deputy secretary-general of the Hami delegation of the Communist Party of China and the director of the Office of Economics and Management, Guan Baijun, told reporters that according to the requirements of Xinjiang’s leap-forward development, by 2020, Hami’s power installed capacity, which is dominated by the energy industry, will reach 32.8 million kilowatts. Due to the poor power channel, Hami's thermal power installed capacity was only 350,000 kilowatts at the end of 2009. If the country does not open the power transmission channel from Xinjiang to the central and eastern regions on a large scale, the leap-forward development that Xinjiang is trying to achieve will not be discussed again.
Misplaced power development concept
Some central and eastern provinces believe that the large-scale introduction of electricity from the northwest to the province will affect the province's interests. For a long time, these provinces prefer to build their own thermal power plants and are not willing to introduce electricity from outside.
China has proposed that the construction of the “West-to-East Power Transmission†in the northwest has been carried out for many years. Why has it not been able to be built on a large scale so far? According to industry insiders, this is mainly due to the misplaced power development concept in some provinces in the central and eastern regions. It is believed that the large-scale introduction of electricity from the northwest to the province will affect the interests of the province. Therefore, for a long period of time, these provinces prefer to build their own thermal power plants. And are not willing to introduce electricity from outside.
According to the "Economic Information Daily" reporter, as early as 2007, the power companies in the five northwestern provinces planned a power transmission channel to the east, but were rejected by a province in the east. The reporter learned from interviews in some provinces in the east that some leaders here have a lot of misplaced energy development concepts, which are roughly three points.
First, I believe that the construction of thermal power can solve the problem of local “electricity shortageâ€. Therefore, I have paid too much attention to building coal-fired power plants for a long time. Every time there is an “electricity shortageâ€, they accelerate the construction of thermal power units. This makes the demand for thermal coal larger and the transportation of coal is more tense. As a result, it is more likely to cause a “power shortage†and a vicious circle.
What is even more worrying is that according to the national plan, by 2020, China will strive to achieve the goal of 1 kilowatt per capita installed capacity, and most of the central and eastern regions of China have not yet reached this goal, which means that some often occur. The area of ​​electricity shortage is
In the next 10 years, the development of thermal power units may be accelerated on a large scale. This will objectively increase the power of drama, the shortage of electricity and coal, and the frequent occurrence of “electricity shortagesâ€.
Second, I believe that the development of thermal power is conducive to the increase of GDP. An eastern city leader told reporters frankly that the development of thermal power plants is of great significance to the city and can quickly drive local GDP growth. In fact, from the long-term development of a province, the words of the eastern city leaders are biased. On the one hand, the electricity in the northwest is relatively cheaper than the coal-producing area, even if it is transported to the central and eastern regions through the “electric highwayâ€. According to Cao Shengshun, director of the Development Planning Department of Northwest Power Grid Co., Ltd., it is estimated that if the electricity is exported from Xinjiang Hami to Zhengzhou, the price of the landing will be one cent lower than the local benchmark price in Zhengzhou. Cheap electricity can effectively reduce the production costs of enterprises. On the other hand, from an environmental point of view, the development of thermal power plants themselves has to bear considerable environmental protection costs, but transmission does not have this problem. Therefore, from the perspective of the benefits of economic development in a province, it is much more cost-effective to purchase cheap electricity from outside than to develop thermal power.
Third, some leaders in the central and eastern regions believe that the development of thermal power is conducive to the employment of ordinary people, which is also supported by many local people. It should be said that if you use power transmission instead of your own power, it will affect the employment of some people. There are two main types of employment that can be driven by the development of thermal power. First, people directly related to thermal power generation. With the current performance improvement of thermal power units, there are not many people in this part. Another point is that people who are involved in transporting coal will have a greater impact on the people if they do not develop thermal power. However, the nation’s transportation tensions will be greatly alleviated.
Need the country to make a decision as soon as possible
Not long ago, the Xinjiang Uygur Autonomous Region government has issued a special report to the State Council on the construction of two UHV transmission projects, and reported a special report on a single project, which is the first time in Xinjiang history.
Industry insiders said that it is necessary to fundamentally solve the "electricity shortage" and other issues. At present, China's efforts to accelerate the construction of power channels are urgent. From an objective point of view, China now has the requirement to speed up the construction of power channels. At present, it is only necessary for the state to implement the plan as soon as possible.

Not long ago, the Xinjiang Uygur Autonomous Region government has issued a special report to the State Council on the construction of two UHV transmission projects, and reported a special report on a single project, which is the first time in Xinjiang history.
Industry insiders said that it is necessary to fundamentally solve the "electricity shortage" and other issues. At present, China's efforts to accelerate the construction of power channels are urgent. From an objective point of view, China now has the requirement to speed up the construction of power channels. At present, it is only necessary for the state to implement the plan as soon as possible.
According to Su Shengxin, general manager of Xinjiang Electric Power Company, the State Grid has made plans to prepare two UHV transmission projects in Xinjiang during the 12th Five-Year Plan period. One is the Hami--Zhengzhou 800 kV line. It plans to invest 40 billion yuan, and the other is the 1000 kV line in Xinjiang's Zhundong--Chongqing, with a planned investment of 45 billion yuan. According to calculations, such a transmission capacity requires an installed capacity of 22 to 23 million kilowatts, and can convert 50 million tons of raw coal per year. At present, the total coal output in Xinjiang is about 80 million tons, which means that Xinjiang's coal production capacity can be doubled.
In terms of wind power, according to the ratio of wind power and thermal power 1:2, only Hami--Zhengzhou can increase the installed capacity of wind power in Xinjiang by 2.5 million kilowatts, which is 2.5 times of the current wind power scale in Xinjiang. It is conservatively estimated that this project will directly drive investment of 100 billion yuan. By then, Xinjiang can achieve leap-forward development and promote the simultaneous entry of Xinjiang and the mainland into a well-off society. Not long ago, the Xinjiang Uygur Autonomous Region government has made a special report to the State Council on this plan, and reported a special report to the autonomous region government on a single project, which is the first time in Xinjiang history.
In addition, some provinces in the central and eastern regions have begun to reflect on the misplaced concept of power development and gradually recognize the practice of transmitting electricity from other places. This aspect is particularly prominent in Shandong Province. In 2008, Shandong Province, which had always lacked electricity, suffered the most serious “electricity shortage†in the past 10 years, and the gap was as high as one-third. The single power structure makes Shandong people realize that if they want to break through the bottleneck of energy supply, they must vigorously implement the strategy of “external power into Lu†to realize the rational layout of Shandong power supply.
According to the "Economic Information Daily" reporter, in 2008, Shandong purchased electricity from the North China Power Grid for the first time, purchasing electricity for 2.95 billion kWh per year. In 2009, Shandong purchased electricity at 7.141 billion kWh; from January to July this year, the electricity purchased has been purchased. It reached 9.47 billion kWh, which has exceeded 33% of the total purchased electricity last year. “External power into Lu†not only improved the energy supply in Shandong, but also promoted energy saving and emission reduction in the province. According to estimates, Shandong Power Grid accepts 4 million kilowatts of electricity outside the province, saving 11.2 million tons of raw coal and reducing sulfur dioxide emissions by 57,000 tons per year.
The power input side and the output side can be said to have gradually prepared for the event, and everything is only waiting for the large-scale construction of the "West-to-East Power Transmission" channel in the northwest. Yu Xinqiang, general manager of Northwest Power Grid Co., Ltd. said that it can now be said that "everything is ready, only owing to the east wind", it is indeed time to speed up the construction of power transmission channels in energy-rich areas such as the Northwest. The state should include the power transmission of energy-rich areas such as the Northwest, including Xinjiang, into the “12th Five-Year Plan†energy development strategy, and build the Northwest Region as the main resource provider of the national electricity market. Solve the fundamental way of contradiction between domestic electricity supply and demand.
Although the "electric highway" has been opened this winter, there may still be "electricity shortage".
In recent years, after the winter, there have been serious “electricity shortages†in some areas of central and eastern provinces in China. On November 3, with the opening of the first “electric highway†from Xinjiang to the mainland – the 750 kV network project between Xinjiang and the Northwest Power Grid, industry insiders said that this move “opened the largest energy “water tap†in Chinaâ€. Xinjiang's power development is expected to have a qualitative leap. If these electricity can be sent smoothly, it will greatly alleviate the winter “electricity shortage†phenomenon in the central and eastern regions. Then, will there be a "power shortage" this winter? Many industry insiders interviewed by the Economic Information Daily said that there have been no fundamental changes in the factors affecting the relationship between power supply and demand. In this winter, there may still be “electricity shortages†in some areas of China.
Winter “electricity shortage†frequently appears
In recent years, in some areas of central and eastern China, especially in central China and parts of eastern China, the phenomenon of “electricity shortage†in winter has become very serious. Take Hubei Province as an example. In the peak of “electricity shortage†last winter, the power shortage in Hubei Province was close to 3 million kilowatts, and the daily electricity consumption gap exceeded 50 million kilowatt hours.
The frequent occurrence of “electricity shortage†in these local areas in China is due to various reasons. From the perspective of power demand, in recent years, especially after the international financial crisis in 2008, the state has introduced policies to increase investment and restore the economy. A large number of industrial projects have been launched in various places, and these projects need to consume a large amount of electricity. Since then, as China's economy has stabilized and rebounded, it has effectively boosted the consumption of electricity. In 2008, Shandong Province, which had always lacked electricity, suffered the most serious “electricity shortage†in the past 10 years, and the gap was as high as one-third. In the same year, Shandong purchased electricity from the North China Power Grid for the first time, and purchased electricity for 2.95 billion kWh a year.
In addition, the seasonal increase in electricity consumption in the winter has led to a significant increase in the demand for electricity in many provinces in recent years. According to data provided by the National Energy Administration, in November 2009, the national total electricity consumption was 328.388 billion kWh, an increase of 4.77% from the previous month and a year-on-year increase of 27.63%.
From the perspective of power supply, China's central and eastern regions are mainly thermal power generation, and their power generation depends on the installed capacity on the one hand and the full supply of coal from the other. In recent years, the growth rate of installed capacity in the central and eastern regions is not slow. However, due to the influence of winter snow and ice weather on transportation, and the contradiction between coal and electricity caused by the delaying energy price mechanism, electricity in the central and eastern regions It is difficult to ensure sufficient supply of coal in the winter, and the power cannot be supplied normally.
According to Yang Yong, deputy chief engineer of Hubei Electric Power Company, the direct cause of the lack of electricity in Hubei Province last winter was that the power plant in the province was not guaranteed, causing the generator set to be shut down. According to information released by the Hubei Provincial Economic Commission, due to lack of coal, on January 7, 2010, only 36 units of 200 units with a capacity of 200,000 kilowatts and above were opened in Hubei Province.
“Electricity shortage†is a partial shortage under the balance of supply and demand across the country
In fact, from the perspective of the national power supply and demand relationship, the current "electricity shortage" in China is actually a partial shortage under the balance of supply and demand across the country. There is no substantial "electricity shortage" in China. Generally speaking, China's power supply and demand is basically balanced and slightly surplus, but there is a recent imbalance in some areas. This imbalance is mainly due to the fact that some areas where “electricity shortage†occurred have long paid too much attention to the construction of thermal power plants, and neglected the long-distance transmission of energy supply methods, resulting in the suspension of transportation of some generators caused by the shortage of coal in the region. In the northwest and other regions where energy is concentrated, there is electricity that cannot be exported.
China's energy distribution is extremely unbalanced. The eastern region has developed economy, energy consumption is large, energy resources are scarce, and the economically underdeveloped northwest region is extremely rich in energy. Shaanxi, Gansu, Ning, Qing, and new coal prospective reserves are as high as 23,893. About 100 million tons, accounting for about half of the country's total, the theoretical reserves of hydropower resources are also more than 84 million kilowatts, accounting for more than 12% of the country. By the end of 2009, the total installed capacity of Shaanxi, Gansu, Ningxia, Qinghai and New Power was 67.278 million kilowatts, while the maximum power load of the Northwest Power Grid was only 31.59 million kilowatts. The annual surplus power reached 100 billion kilowatt hours. Except for the isolated operation of Xinjiang's power grid, these surplus powers cannot be sent out, and others can be sent out.
According to Su Shengxin, general manager of Xinjiang Electric Power Company, Xinjiang is the province with the largest potential for power development and power transmission in China. At present, Xinjiang's coal reserves account for about 40% of the national total, ranking first in the country; the total reserves of wind energy resources reached 886 million kilowatts, and the technology developable capacity is 120 million kilowatts, ranking second in the country; China's latitudes are 10-15% higher, second only to Tibet, ranking second in the country. Thermal power, wind power, and optoelectronics all have great potential for development.
However, because Xinjiang Power Grid was previously disconnected from the mainland power grid, by 2008, the total installed capacity of power generation in Xinjiang was 10.879 million kilowatts, and the power generation capacity was 48.9 billion kilowatt hours. Compared with other provinces in the northwest, the power generation was not large. On November 3, with the opening of the first “electric highway†from Xinjiang to the mainland – the 750 kV network project between Xinjiang and the Northwest Power Grid, industry insiders said that this move “opened the largest energy “water tap†in Chinaâ€. Xinjiang's power development is expected to have a qualitative leap. According to the Xinjiang power supply construction plan, it is estimated that the total installed capacity in Xinjiang in 2015 will reach 34.6-39.5 million kilowatts, and the maximum external power transmission will be 9.2 million kilowatts. If these electricity can be sent smoothly, it will greatly alleviate the winter “electricity shortage†phenomenon in the central and eastern regions.
This winter's "electricity shortage" is still difficult to avoid
The opening of China's largest energy “water tap†has brought great hopes to solve the “electricity shortage†this winter. However, from the current investigation of reporters, there are still no fundamental changes due to factors affecting the relationship between power supply and demand. In winter, there may still be “electricity shortages†in some parts of China.
From the perspective of power demand, according to the data provided by the National Energy Administration, China's power market has shown a “high before and low†trend this year. However, considering the impact of the high base last year, the absolute amount of electricity used in China is still gradually increasing. Upward trend.
Judging from the power supply, the supply of coal this winter will not be particularly smooth. The importance of the smooth supply of coal is important because of the tightness of coal transportation. It is understood that since 1993, China's coal railway transportation satisfaction rate has continued to decline. In 2006, the national average railway railway transportation satisfaction rate was only 35%. In the case of special weather, especially winter snow and ice, transportation is affected, and coal transportation is more tense. This often leads to tight supply of coal in some areas of central and eastern China, and there is a “power shortageâ€. Since last year to this year, China's coal transportation conditions have not undergone fundamental changes.
At the same time, although the first “electric highway†from Xinjiang to the mainland has been opened, due to the delay in the opening of China’s “West-to-East Power Transmission†in the northwest, only a small part of Xinjiang’s surplus power can be used in the Northwest Power Grid. It is impossible to export to the central and eastern regions on a large scale. This energy “water tap†cannot function effectively this year. At present, there are only two power passages from the northwest to the outside. One is from Shaanxi Weinan and Henan Lingbao, and the other is to take Shaanxi Baoji into Sichuan. These two passages are not large. In 2009, the Northwest Power Grid accumulated electricity. At only 3.63 billion kWh, this point of external power supply will not have much impact on power supply and demand.
Therefore, there may still be tensions in the national electricity supply this winter. For this judgment, Wang Siqiang, deputy director of the Comprehensive Department of the National Energy Administration, also agreed. He said at the quarterly energy economic situation conference held by the National Energy Administration in October this year that this situation will occur in local areas and peak hours. Affected by the grid and power supply structure and partial watersheds in winter, especially due to factors such as coal supply, incoming water and temperature, some provinces in central China may still have tight power supply.
On November 3, the first “electric highway†from Xinjiang to the mainland – the 750 kV network project of Xinjiang and Northwest Power Grid was officially opened. The opening of China’s largest energy “water tap†is to solve the “electricity†that has occurred frequently in recent years. The wasteland offers possibilities. However, due to the delay in the large-scale opening of China’s “West-to-East Power Transmission†to the central and eastern regions, only a small part of Xinjiang’s surplus power is used in the Northwest Power Grid through this “highwayâ€, but it is still unable to be large-scale. Lost to the central and eastern regions. According to industry insiders, a large amount of surplus electricity is difficult to release in the northwest, which not only greatly restricts the role of this "electric highway", but also has many negative effects on China's economy.
Poor power channels cause many negative effects
The large amount of surplus power in the northwest has created a strong “force†effect on the surge of high-energy-consuming industries. For such a situation, the northwestern provincial governments and the power sector are well aware, but out of the economic development of the provinces. The consideration is that it is difficult to change the development trend of this industry.
The passage of “West-to-East Power Transmission†in the northwest has not been opened on a large scale, which has brought many negative effects to the development of China’s economy.
First, it is impossible to solve the problem of “power shortage†fundamentally. Yu Xinqiang, general manager of Northwest Power Grid Co., Ltd. said that the current power shortage in China is actually not a lack of generator sets, but a lack of coal. "Lack of coal --- shutdown --- pull the brakes --- power cut --- then increase the unit --- more lack of coal", in recent years has become a part of Central China, East China in the energy development can not get out A strange circle. To get out of this strange circle, only the construction of the power transmission channel will be increased.
Second, a large amount of surplus electricity was “would†in the northwest, which greatly stimulated the excessive development of local high-energy-consuming industries. For example, in Qinghai from 2004 to 2006, electricity consumption increased by 32.6%, 10.34%, and 19.96%, respectively. Ningxia's annual electricity consumption increased by 30.3%, 14.96%, and 29.14%, respectively, while the GDP of the two provinces increased during the same period. The speed is much lower than the increase in electricity consumption. The proportion of electricity consumption in high-energy-consuming industries in the two provinces has also been increasing. The proportion of electricity consumption in high-energy-consuming industries in Qinghai from 2004 to 2006 was 76.43%, 77.6%, and 78.66%, respectively. The proportion of electricity consumption in high-energy-consuming industries in Ningxia was 65.47. %, 67.29%, and 69.46%, the industrial energy consumption of the two provinces tends to be high and energy-consuming. This highly energy-intensive industrial development trend has directly led to a surprisingly high energy consumption in the northwest. For example, Ningxia's GDP per unit of energy consumption is the highest in the country.
The large amount of surplus power in the northwest has created a strong “force†effect on the surge of high-energy-consuming industries. For such a situation, the northwestern provincial governments and the power sector are well aware, but out of the economic development of the provinces. The consideration is that it is difficult to change the development trend of this industry. In fact, high-energy-consuming industries have become the leading industries in many regions of the Northwest, and at the same time they are the largest customers of electricity consumption. The dependence of the two sides is quite high. “Selling coal-selling electricity-selling high-energy-consuming products†has become the northwestern Three important steps in the continuous upgrading of resource development strategies in less regions. According to forecasts, from 2008 to 2020, only Qinghai Province will have a surplus of 2.9 to 9.07 million kilowatts of electricity, with a surplus of between 8 and 31.5 billion kWh. If the problem of northwest power transmission cannot be solved well, the situation that surplus power will “force†the surge in high-energy-consuming enterprises will further intensify.
Third, the poor transmission of the power transmission channel makes Xinjiang unable to play its biggest economic advantage--energy advantage, and the accelerated development of Xinjiang's economy is greatly restricted. The deputy secretary-general of the Hami delegation of the Communist Party of China and the director of the Office of Economics and Management, Guan Baijun, told reporters that according to the requirements of Xinjiang’s leap-forward development, by 2020, Hami’s power installed capacity, which is dominated by the energy industry, will reach 32.8 million kilowatts. Due to the poor power channel, Hami's thermal power installed capacity was only 350,000 kilowatts at the end of 2009. If the country does not open the power transmission channel from Xinjiang to the central and eastern regions on a large scale, the leap-forward development that Xinjiang is trying to achieve will not be discussed again.
Misplaced power development concept
Some central and eastern provinces believe that the large-scale introduction of electricity from the northwest to the province will affect the province's interests. For a long time, these provinces prefer to build their own thermal power plants and are not willing to introduce electricity from outside.
China has proposed that the construction of the “West-to-East Power Transmission†in the northwest has been carried out for many years. Why has it not been able to be built on a large scale so far? According to industry insiders, this is mainly due to the misplaced power development concept in some provinces in the central and eastern regions. It is believed that the large-scale introduction of electricity from the northwest to the province will affect the interests of the province. Therefore, for a long period of time, these provinces prefer to build their own thermal power plants. And are not willing to introduce electricity from outside.
According to the "Economic Information Daily" reporter, as early as 2007, the power companies in the five northwestern provinces planned a power transmission channel to the east, but were rejected by a province in the east. The reporter learned from interviews in some provinces in the east that some leaders here have a lot of misplaced energy development concepts, which are roughly three points.
First, I believe that the construction of thermal power can solve the problem of local “electricity shortageâ€. Therefore, I have paid too much attention to building coal-fired power plants for a long time. Every time there is an “electricity shortageâ€, they accelerate the construction of thermal power units. This makes the demand for thermal coal larger and the transportation of coal is more tense. As a result, it is more likely to cause a “power shortage†and a vicious circle.
What is even more worrying is that according to the national plan, by 2020, China will strive to achieve the goal of 1 kilowatt per capita installed capacity, and most of the central and eastern regions of China have not yet reached this goal, which means that some often occur. The area of ​​electricity shortage is
In the next 10 years, the development of thermal power units may be accelerated on a large scale. This will objectively increase the power of drama, the shortage of electricity and coal, and the frequent occurrence of “electricity shortagesâ€.
Second, I believe that the development of thermal power is conducive to the increase of GDP. An eastern city leader told reporters frankly that the development of thermal power plants is of great significance to the city and can quickly drive local GDP growth. In fact, from the long-term development of a province, the words of the eastern city leaders are biased. On the one hand, the electricity in the northwest is relatively cheaper than the coal-producing area, even if it is transported to the central and eastern regions through the “electric highwayâ€. According to Cao Shengshun, director of the Development Planning Department of Northwest Power Grid Co., Ltd., it is estimated that if the electricity is exported from Xinjiang Hami to Zhengzhou, the price of the landing will be one cent lower than the local benchmark price in Zhengzhou. Cheap electricity can effectively reduce the production costs of enterprises. On the other hand, from an environmental point of view, the development of thermal power plants themselves has to bear considerable environmental protection costs, but transmission does not have this problem. Therefore, from the perspective of the benefits of economic development in a province, it is much more cost-effective to purchase cheap electricity from outside than to develop thermal power.
Third, some leaders in the central and eastern regions believe that the development of thermal power is conducive to the employment of ordinary people, which is also supported by many local people. It should be said that if you use power transmission instead of your own power, it will affect the employment of some people. There are two main types of employment that can be driven by the development of thermal power. First, people directly related to thermal power generation. With the current performance improvement of thermal power units, there are not many people in this part. Another point is that people who are involved in transporting coal will have a greater impact on the people if they do not develop thermal power. However, the nation’s transportation tensions will be greatly alleviated.
Need the country to make a decision as soon as possible
Not long ago, the Xinjiang Uygur Autonomous Region government has issued a special report to the State Council on the construction of two UHV transmission projects, and reported a special report on a single project, which is the first time in Xinjiang history.
Industry insiders said that it is necessary to fundamentally solve the "electricity shortage" and other issues. At present, China's efforts to accelerate the construction of power channels are urgent. From an objective point of view, China now has the requirement to speed up the construction of power channels. At present, it is only necessary for the state to implement the plan as soon as possible.
Although the first "electric highway" from Xinjiang to the mainland was opened, the role of the "West-to-East Power Transmission" to the central and eastern regions has not been opened on a large scale, so the effect is limited.
On November 3, the first “electric highway†from Xinjiang to the mainland – the 750 kV network project of Xinjiang and Northwest Power Grid was officially opened. The opening of China’s largest energy “water tap†is to solve the “electricity†that has occurred frequently in recent years. The wasteland offers possibilities. However, due to the delay in the large-scale opening of China’s “West-to-East Power Transmission†to the central and eastern regions, only a small part of Xinjiang’s surplus power is used in the Northwest Power Grid through this “highwayâ€, but it is still unable to be large-scale. Lost to the central and eastern regions. According to industry insiders, a large amount of surplus electricity is difficult to release in the northwest, which not only greatly restricts the role of this "electric highway", but also has many negative effects on China's economy.
Poor power channels cause many negative effects

Industry insiders said that it is necessary to fundamentally solve the "electricity shortage" and other issues. At present, China's efforts to accelerate the construction of power channels are urgent. From an objective point of view, China now has the requirement to speed up the construction of power channels. At present, it is only necessary for the state to implement the plan as soon as possible.
According to Su Shengxin, general manager of Xinjiang Electric Power Company, the State Grid has made plans to prepare two UHV transmission projects in Xinjiang during the 12th Five-Year Plan period. One is the Hami--Zhengzhou 800 kV line. It plans to invest 40 billion yuan, and the other is the 1000 kV line in Xinjiang's Zhundong--Chongqing, with a planned investment of 45 billion yuan. According to calculations, such a transmission capacity requires an installed capacity of 22 to 23 million kilowatts, and can convert 50 million tons of raw coal per year. At present, the total coal output in Xinjiang is about 80 million tons, which means that Xinjiang's coal production capacity can be doubled.
In terms of wind power, according to the ratio of wind power and thermal power 1:2, only Hami--Zhengzhou can increase the installed capacity of wind power in Xinjiang by 2.5 million kilowatts, which is 2.5 times of the current wind power scale in Xinjiang. It is conservatively estimated that this project will directly drive investment of 100 billion yuan. By then, Xinjiang can achieve leap-forward development and promote the simultaneous entry of Xinjiang and the mainland into a well-off society. Not long ago, the Xinjiang Uygur Autonomous Region government has made a special report to the State Council on this plan, and reported a special report to the autonomous region government on a single project, which is the first time in Xinjiang history.
In addition, some provinces in the central and eastern regions have begun to reflect on the misplaced concept of power development and gradually recognize the practice of transmitting electricity from other places. This aspect is particularly prominent in Shandong Province. In 2008, Shandong Province, which had always lacked electricity, suffered the most serious “electricity shortage†in the past 10 years, and the gap was as high as one-third. The single power structure makes Shandong people realize that if they want to break through the bottleneck of energy supply, they must vigorously implement the strategy of “external power into Lu†to realize the rational layout of Shandong power supply.
According to the "Economic Information Daily" reporter, in 2008, Shandong purchased electricity from the North China Power Grid for the first time, purchasing electricity for 2.95 billion kWh per year. In 2009, Shandong purchased electricity at 7.141 billion kWh; from January to July this year, the electricity purchased has been purchased. It reached 9.47 billion kWh, which has exceeded 33% of the total purchased electricity last year. “External power into Lu†not only improved the energy supply in Shandong, but also promoted energy saving and emission reduction in the province. According to estimates, Shandong Power Grid accepts 4 million kilowatts of electricity outside the province, saving 11.2 million tons of raw coal and reducing sulfur dioxide emissions by 57,000 tons per year.
The power input side and the output side can be said to have gradually prepared for the event, and everything is only waiting for the large-scale construction of the "West-to-East Power Transmission" channel in the northwest. Yu Xinqiang, general manager of Northwest Power Grid Co., Ltd. said that it can now be said that "everything is ready, only owing to the east wind", it is indeed time to speed up the construction of power transmission channels in energy-rich areas such as the Northwest. The state should include the power transmission of energy-rich areas such as the Northwest, including Xinjiang, into the “12th Five-Year Plan†energy development strategy, and build the Northwest Region as the main resource provider of the national electricity market. Solve the fundamental way of contradiction between domestic electricity supply and demand.
Although the "electric highway" has been opened this winter, there may still be "electricity shortage".
In recent years, after the winter, there have been serious “electricity shortages†in some areas of central and eastern provinces in China. On November 3, with the opening of the first “electric highway†from Xinjiang to the mainland – the 750 kV network project between Xinjiang and the Northwest Power Grid, industry insiders said that this move “opened the largest energy “water tap†in Chinaâ€. Xinjiang's power development is expected to have a qualitative leap. If these electricity can be sent smoothly, it will greatly alleviate the winter “electricity shortage†phenomenon in the central and eastern regions. Then, will there be a "power shortage" this winter? Many industry insiders interviewed by the Economic Information Daily said that there have been no fundamental changes in the factors affecting the relationship between power supply and demand. In this winter, there may still be “electricity shortages†in some areas of China.
Winter “electricity shortage†frequently appears
In recent years, in some areas of central and eastern China, especially in central China and parts of eastern China, the phenomenon of “electricity shortage†in winter has become very serious. Take Hubei Province as an example. In the peak of “electricity shortage†last winter, the power shortage in Hubei Province was close to 3 million kilowatts, and the daily electricity consumption gap exceeded 50 million kilowatt hours.
The frequent occurrence of “electricity shortage†in these local areas in China is due to various reasons. From the perspective of power demand, in recent years, especially after the international financial crisis in 2008, the state has introduced policies to increase investment and restore the economy. A large number of industrial projects have been launched in various places, and these projects need to consume a large amount of electricity. Since then, as China's economy has stabilized and rebounded, it has effectively boosted the consumption of electricity. In 2008, Shandong Province, which had always lacked electricity, suffered the most serious “electricity shortage†in the past 10 years, and the gap was as high as one-third. In the same year, Shandong purchased electricity from the North China Power Grid for the first time, and purchased electricity for 2.95 billion kWh a year.
In addition, the seasonal increase in electricity consumption in the winter has led to a significant increase in the demand for electricity in many provinces in recent years. According to data provided by the National Energy Administration, in November 2009, the national total electricity consumption was 328.388 billion kWh, an increase of 4.77% from the previous month and a year-on-year increase of 27.63%.
From the perspective of power supply, China's central and eastern regions are mainly thermal power generation, and their power generation depends on the installed capacity on the one hand and the full supply of coal from the other. In recent years, the growth rate of installed capacity in the central and eastern regions is not slow. However, due to the influence of winter snow and ice weather on transportation, and the contradiction between coal and electricity caused by the delaying energy price mechanism, electricity in the central and eastern regions It is difficult to ensure sufficient supply of coal in the winter, and the power cannot be supplied normally.
According to Yang Yong, deputy chief engineer of Hubei Electric Power Company, the direct cause of the lack of electricity in Hubei Province last winter was that the power plant in the province was not guaranteed, causing the generator set to be shut down. According to information released by the Hubei Provincial Economic Commission, due to lack of coal, on January 7, 2010, only 36 units of 200 units with a capacity of 200,000 kilowatts and above were opened in Hubei Province.
“Electricity shortage†is a partial shortage under the balance of supply and demand across the country
In fact, from the perspective of the national power supply and demand relationship, the current "electricity shortage" in China is actually a partial shortage under the balance of supply and demand across the country. There is no substantial "electricity shortage" in China. Generally speaking, China's power supply and demand is basically balanced and slightly surplus, but there is a recent imbalance in some areas. This imbalance is mainly due to the fact that some areas where “electricity shortage†occurred have long paid too much attention to the construction of thermal power plants, and neglected the long-distance transmission of energy supply methods, resulting in the suspension of transportation of some generators caused by the shortage of coal in the region. In the northwest and other regions where energy is concentrated, there is electricity that cannot be exported.
China's energy distribution is extremely unbalanced. The eastern region has developed economy, energy consumption is large, energy resources are scarce, and the economically underdeveloped northwest region is extremely rich in energy. Shaanxi, Gansu, Ning, Qing, and new coal prospective reserves are as high as 23,893. About 100 million tons, accounting for about half of the country's total, the theoretical reserves of hydropower resources are also more than 84 million kilowatts, accounting for more than 12% of the country. By the end of 2009, the total installed capacity of Shaanxi, Gansu, Ningxia, Qinghai and New Power was 67.278 million kilowatts, while the maximum power load of the Northwest Power Grid was only 31.59 million kilowatts. The annual surplus power reached 100 billion kilowatt hours. Except for the isolated operation of Xinjiang's power grid, these surplus powers cannot be sent out, and others can be sent out.
According to Su Shengxin, general manager of Xinjiang Electric Power Company, Xinjiang is the province with the largest potential for power development and power transmission in China. At present, Xinjiang's coal reserves account for about 40% of the national total, ranking first in the country; the total reserves of wind energy resources reached 886 million kilowatts, and the technology developable capacity is 120 million kilowatts, ranking second in the country; China's latitudes are 10-15% higher, second only to Tibet, ranking second in the country. Thermal power, wind power, and optoelectronics all have great potential for development.
However, because Xinjiang Power Grid was previously disconnected from the mainland power grid, by 2008, the total installed capacity of power generation in Xinjiang was 10.879 million kilowatts, and the power generation capacity was 48.9 billion kilowatt hours. Compared with other provinces in the northwest, the power generation was not large. On November 3, with the opening of the first “electric highway†from Xinjiang to the mainland – the 750 kV network project between Xinjiang and the Northwest Power Grid, industry insiders said that this move “opened the largest energy “water tap†in Chinaâ€. Xinjiang's power development is expected to have a qualitative leap. According to the Xinjiang power supply construction plan, it is estimated that the total installed capacity in Xinjiang in 2015 will reach 34.6-39.5 million kilowatts, and the maximum external power transmission will be 9.2 million kilowatts. If these electricity can be sent smoothly, it will greatly alleviate the winter “electricity shortage†phenomenon in the central and eastern regions.
This winter's "electricity shortage" is still difficult to avoid
The opening of China's largest energy “water tap†has brought great hopes to solve the “electricity shortage†this winter. However, from the current investigation of reporters, there are still no fundamental changes due to factors affecting the relationship between power supply and demand. In winter, there may still be “electricity shortages†in some parts of China.
From the perspective of power demand, according to the data provided by the National Energy Administration, China's power market has shown a “high before and low†trend this year. However, considering the impact of the high base last year, the absolute amount of electricity used in China is still gradually increasing. Upward trend.
Judging from the power supply, the supply of coal this winter will not be particularly smooth. The importance of the smooth supply of coal is important because of the tightness of coal transportation. It is understood that since 1993, China's coal railway transportation satisfaction rate has continued to decline. In 2006, the national average railway railway transportation satisfaction rate was only 35%. In the case of special weather, especially winter snow and ice, transportation is affected, and coal transportation is more tense. This often leads to tight supply of coal in some areas of central and eastern China, and there is a “power shortageâ€. Since last year to this year, China's coal transportation conditions have not undergone fundamental changes.
At the same time, although the first “electric highway†from Xinjiang to the mainland has been opened, due to the delay in the opening of China’s “West-to-East Power Transmission†in the northwest, only a small part of Xinjiang’s surplus power can be used in the Northwest Power Grid. It is impossible to export to the central and eastern regions on a large scale. This energy “water tap†cannot function effectively this year. At present, there are only two power passages from the northwest to the outside. One is from Shaanxi Weinan and Henan Lingbao, and the other is to take Shaanxi Baoji into Sichuan. These two passages are not large. In 2009, the Northwest Power Grid accumulated electricity. At only 3.63 billion kWh, this point of external power supply will not have much impact on power supply and demand.
Therefore, there may still be tensions in the national electricity supply this winter. For this judgment, Wang Siqiang, deputy director of the Comprehensive Department of the National Energy Administration, also agreed. He said at the quarterly energy economic situation conference held by the National Energy Administration in October this year that this situation will occur in local areas and peak hours. Affected by the grid and power supply structure and partial watersheds in winter, especially due to factors such as coal supply, incoming water and temperature, some provinces in central China may still have tight power supply.
