On the 4th, the Xinjiang-Northwest 750-kV networking project was completed and put into operation, which also marked the end of the history of isolated-network operation in Xinjiang Power Grid and formally merged into the national power grid, making Xinjiang's thermal power and wind power “bundling†become a reality. .
According to Liu Zhenya, general manager of the State Grid Corporation of China, the project is one of the 23 key projects identified by the State for the development of the western region in 2010. It is an important project for the State Grid Corporation of China to implement the national strategy for western development and realize the interconnection of the national power stations. The project starts from the 750 kV Ukrainian substation in Xinjiang and ends at the 750 kV Yongdeng substation in Gansu Province. It consists of 7 substations and 12 lines. The total length is 2×1780 km, and the substation capacity is 12,900,000 kVA. The total investment is 160. Billion yuan is the world’s largest and longest-lined, most complex 750-kilovolt power transmission project. Among them, there are 4 substations in the Xinjiang section of the project, with a total length of 1691 kilometers and a total investment of 6.693 billion yuan.
“This is the 'Silk Road' for the 21st century,†Liu Zhenya said. “After the project is put into operation, it effectively solves the bottleneck problem of thermal power and wind power transmission in Xinjiang, and realizes the networking of Xinjiang Power Grid and Northwest Power Grid to promote Xinjiang. It is of great significance to develop energy resources and realize the 'distribution of the Xinjiang power'."
At present, Xinjiang has 2.2 trillion tons of coal reserves, accounting for 40% of the country's total. It ranks first in the country, and its wind energy reserves rank among the top countries in the country. It also has the conditions for the development of comprehensive energy bases, such as coal-fired power and wind power, which are complementary and have been identified. The construction of energy and new energy bases, together with the construction of photovoltaic power stations in the west and wind power bases in the west, all make the “distribution of power from the east to the east†extremely important.
Su Shengxin, general manager of Xinjiang Electric Power Co., Ltd., said: "The Xinjiang Power Company will accelerate the construction of a 750-kilovolt backbone grid with coordinated development of the voltage levels at all levels of the strong intelligent delivery network in Xinjiang, and strive to promote the 'high-voltage transmission of Xinjiang'. Start implementation as soon as possible."
It is reported that before the Xinjiang-Northwest 750 kV networking project was put into operation, Xinjiang Power Grid was also one of the only two independent power grids in China (Xinjiang and Tibet).
Xinjiang has a late-advantage but needs to build a high house
On the 4th, the reporter interviewed Hu Zhaoguang, vice president of the National Grid Energy Research Institute, on the significance of the 750-kV networking project.
Note: After Xinjiang's enriched energy has been developed and converted into electricity, it can meet the growth in electricity demand in Xinjiang and at the same time it can realize the “Jiangdong Power Transmissionâ€. What is the significance of this for Xinjiang and the eastern provinces?
Hu Zhaoguang: The power-on operation of the networking project has important implications for Xinjiang and even the eastern region. Xinjiang’s resources are abundant, but in terms of the development stage, the development rate is relatively slow. At the same time as the economic development of the eastern provinces and regions, the lack of electricity supply has also become one of the factors that restrict the growth rate of the economy. Through networking, the resources of the two parties are realized. Complementary advantages will be to convert Xinjiang's wind power and coal into electricity, transport it to the eastern provinces and districts to replenish their electricity demand, and drive the economic development of both sides.
Reporter: As we all know, “West Power Transmission to the West†refers to the development of power resources in the western provinces of Guizhou, Yunnan, Guangxi, Sichuan, Inner Mongolia, and Shanxi. Then, what are the advantages and disadvantages of “Jiangdian East Power Transmission�
Hu Zhaoguang: Because of the different geographical locations, the role of “West-to-East Electricity Transmission†in the western provinces and provinces is not the same. It is not a contradiction in the transmission of electricity. In comparison, the advantages of hydropower resources in other provinces and regions are different. Obviously, in Xinjiang, the “bundling†of wind power and coal-fired power is mainly sent for delivery. Due to the tilt of the central government on Xinjiang’s development policy, it will also play an important role in promoting “Jiangdong Power Transmission†and Xinjiang’s economic development in the future.
Note: For Xinjiang, after the power grid is connected, more opportunities will come. The strategic investment of power generation companies in the next ten years will be over 100 billion yuan. In the new round of development and construction, it will be for enterprises and Xinjiang. What are the pros and cons and what should Xinjiang pay attention to in terms of environmental protection?
Hu Zhaoguang: For Xinjiang's energy development, we can now use a “white paper†to compare it. In this round of development and construction, Xinjiang has a late-stage advantage. On this basis, the future development must also be “high-profileâ€. It will surely bypass the problems that have arisen in the development of the eastern part of the country, learn from experience and draw lessons from it, and will directly use the most advanced technologies and better environmental protection products to abandon past deficiencies.
Now Xinjiang's electricity has entered a period of high-speed operation. In the future, during the “Twelfth Five-Year Plan†and even “Thirteenth Five-Year Plan†period, how will Xinjiang's 750-kilovolt power grid be constructed and its development prospects?
Hu Zhaoguang: As the saying goes, "Economic development, power first," now Xinjiang's electricity has entered the era of high-speed operation, then the next step for enterprises to build power plants, development of coal chemical industry or other projects, will surely drive the local GDP, employment and tax revenue growth. .
These are just the beginnings. In the future development, the impact of electricity will also bring about more impacts on Xinjiang's overall economy and the general improvement of residents' income levels. It is believed that in the next 5 to 10 years, Xinjiang will develop faster than the east. area.
On the 4th, the reporter learned from the interview that because of the big cake of “Jiangdong Power Transmission to the Eastâ€, in the next decade, the five major power generation groups are expected to invest between 1,000 and 150 billion yuan in Xinjiang, and the total investment will exceed 500 billion yuan. With the investment of other energy companies, the total investment in the field of coal and electricity will exceed 1 trillion yuan in the next decade. Xinjiang has become the new focus of the next round of energy competition.
According to Han Bo, the director of the planning and development department of Huadian Xinjiang Power Generation Company, "In the next ten years, Huadian Group expects that the investment will be over 100 billion yuan, with an average annual investment of about 10 billion yuan, and annual investment. The total amount is five times that of previous years. Huadian Group must establish coal and electricity coal chemical energy bases, clean energy bases, urban cogeneration bases, and large and medium-sized hydropower bases in Xinjiang."
The relevant person in charge of the Datang Corporation in Xinjiang used a set of figures to analyze the vision of Datang's investment in Xinjiang: In the next ten years, Datang Group's investment in Xinjiang will reach more than 150 billion yuan, and strive to "13th Five-Year Plan". At the end, the installed capacity of power generation reached more than 8 million kilowatts, coal production capacity reached 50 million tons/year, coal-to-natural gas reached 4 billion cubic meters/year, and coal-to-olefins reached 460,000 tons/year.
According to a related person in charge of the power industry, in addition to the investments of the five major power generation companies, if coupled with energy companies such as SDIC Power, Guohua Power, and China Resources Power, it is expected that only the coal-fired The total investment will exceed 1 trillion yuan.
Xinjiang Electric Power Company predicts that by the end of 2015, the installed capacity of Xinjiang will be rapidly increased from 12.8 million kilowatts at the end of 2009 to 60 million kilowatts, of which internal use will only consume 34 million kilowatts, and another 26 million kilowatts will need to be resolved. The rate of delivery rose from zero at the end of the "Eleventh Five-Year Plan" to 43%.
