The released "Twelfth Five-Year Plan" outline clearly proposes the development of large-capacity, high-efficiency, long-distance advanced power transmission technologies such as UHV. As there have been many disputes over UHV construction in academia before, this move not only marks that UHV construction has become a national strategy, but also fully clarifies the expectations of UHV construction, which has given a lot to the capital market concerned about UHV investment opportunities. "Reassurance Pill". State Grid Corporation of China will actively strive for approval for a total of seven UHV lines this year.
UHV rise as a national strategy
The outline clearly states that to meet the requirements of large-scale cross-regional power transmission and new energy power generation grid connection, accelerate the construction of modern power grid system, further expand the scale of west-east power transmission, improve the regional backbone power grid, and develop UHV and other large-capacity, high-efficiency, long-distance power grids. Advanced power transmission technology.
The outline also specifically pointed out in the field of power grids: speed up the construction of large-scale coal power, hydropower and wind power bases for power transmission projects, form a number of cross-regional power transmission channels using advanced UHV technology, and build 200,000 kilometers of transmission lines of 330 kV and above.
A person from the State Grid Corporation of China told this reporter, "It is written into the 'Twelfth Five-Year' plan, which means that it has risen to the national strategy, which will create a better external environment for the next step. We are also actively promoting In the past year or two, there have been signs of power shortage in the eastern region. From the perspective of ensuring power supply and improving energy efficiency, the construction of UHV is particularly urgent."
Bai Jianhua, deputy chief economist of the State Grid Energy Research Institute, said in an interview with this reporter that this marks a determination from the national level: UHV will develop! "This is a very good start, and the specifics still need to be implemented in the planning. If you don't take the UHV road, many things will enter a dead end." In his view, if the coal base continues to export coal mainly, it will fall into There are many problems: insufficient railway coal transportation capacity, excessive road transportation pressure, and too much environmental protection pressure on the user side. Moreover, the major power generation companies have suffered serious losses in coal power, and the accelerated development of UHV can indirectly solve the problem of skyrocketing coal prices caused by intermediate links.
"In addition, after the construction of UHV lines in several major coal power bases in the northwest, there is no need to build transmission channels for wind power alone. For example, Xinjiang has both coal and wind power, and so does Inner Mongolia, while Jiuquan, Gansu has both wind power and Xinjiang and Xinjiang. Outer Mongolia’s coal is used to build thermal power plants, so it can kill two birds with one stone.” Bai Jianhua said, “If we build the wind power transmission channel alone, we calculated the account and sent it to the East China Power Grid for more than 80 cents per kilowatt-hour, and the cost is too high.”
Actively promote route approval
Regarding the progress of UHV work in 2011, the State Grid made it clear: to ensure the approval of the Huainan (South Anhui)-Shanghai UHV AC project in the first quarter, and strive for the approval of the Ximeng-Nanjing, Huainan (Nanjing)-Shanghai UHV AC project in the first half of the year, and Mongolia West-Changsha, Jingbian-Lianyungang UHV AC project and Xiluodu-West Zhejiang, Hami-Henan UHV DC project were approved within the year. Last year's approval progress was slow.
If it is successfully realized, it means that 7 lines will start construction, far exceeding the scale of 2010, which will bring a huge wave of equipment investment. Looking only at the two lines of Xiluodu-Western Zhejiang and Hami-Henan UHV DC projects, Shenwan expects to invest 19.4 billion yuan and 23 billion yuan respectively. And if all 7 lines are built, the investment will be huge.
Zhang Ke revealed that the projects of these seven lines are actively reporting to the Energy Bureau for approval as soon as possible. "The State Grid's definition of the approval progress is to gradually approve, gradually start construction, and gradually put into production according to the degree of need. Of course, there will also be some uncontrollable factors in the approval process."
Zhang Ke told reporters that State Grid Corporation has completed the State Grid's "Twelfth Five-Year" planning system in one year, including a general report and four special reports. Power grid (below 35KV), communication network planning and intelligent planning with important platforms and supports for the development of smart grid, to implement the deployment of the country's "Twelfth Five-Year Plan" in the power grid field.
