Due to the slowdown of power supply in the country, especially the continuous decline in thermal power investment, the growth rate of installed capacity continues to be lower than the growth rate of electricity consumption. In the next few years, the situation of power supply and demand in China will become more severe. As a response, cross-regional power grid construction and smart grid planning, as well as demand-side management, will increase efforts next year, which also brings opportunities for the relevant power equipment industry. If the power industry wants to get out of its predicament, the fundamental way out lies in the marketization of electricity prices, and the continued power shortage will undoubtedly enhance the bargaining power of the power industry.
The grid investment will continue to escalate during the peak period next year. The wastage caused by idle power capacity in China is equally astonishing. The problem of the surplus of western power and the “electricity shortage†problem in the eastern and central regions exist at the same time. The problem of poor transmission channels across regions is still serious, and the resolution of “systematic power shortage†has already been put on the agenda.
According to data provided by the State Grid Corporation of China, the power gap between North China, East China and Central China power grids reached 30 million kilowatts during the summer peak season this year, while the northeast and northwest grids have a surplus of 27 million kilowatts of electric power. "coexist. If we add the Inner Mongolian Mengxi Power Grid, which is more serious than Wowo, the surplus power will exceed 35 million kilowatts, which is enough to make up for the above power shortage.
"The development of electric power should be based on the local balance in the past and the transition to the trans-regional transmission mode." Wei Zhaofeng, full-time deputy director of the China Electric Power Enterprise Federation, said that the power development model based on local balance makes the eastern and central regions unequal Electricity districts rely excessively on coal transmission, and the ratio of coal transmission to coal provinces such as Shanxi Province is 20:1, and the proportion of transmission is obviously low. This has caused a series of problems such as tight transportation capacity, continued rising coal prices, and severely frustrated power generation enthusiasm.
How to solve the problem of insufficient cross-regional transmission capacity? Bai Jianhua, deputy chief economist of the State Grid Energy Research Institute, believes that the future situation depends on the approval and construction progress of UHV cross-regional power grid construction projects and supporting power projects. If it can be successfully completed and put into production, the scope of power shortage will be reduced, and power supply and demand will also be eased.
With the approval of the second UHV line in Shanghai and the acceptance of the expansion project of the Jindongnan UHV line in Huainan, the State Grid has recently accelerated the pace of UHV. It is generally expected that after the expansion project is operated through the load test, the UHV bidding will be accelerated and the demand for related equipment will bring about practical benefits.
"Under the situation that UHV approval is expected to accelerate, and smart investment in grids is gradually increasing, and the prosperity of urban and rural power grids is maintained, the growth rate of investment in the two networks will be between 10% and 15%, or about 430 billion yuan to 440 billion yuan. The focus of investment is mainly on UHV construction, grid intelligence, and distribution network construction, etc. In addition, investment in UHV AC substations will be approximately 117.6 billion yuan in the next few years, and investment in UHV DC converter stations will be approximately 142 billion yuan."
According to the plans of the State Grid and South China Network, the next three years will be the peak period for the development of the power grid. The UHV AC and DC investment during the “Twelfth Five-Year Plan†period will be about 540 billion yuan, and the UHV exchanges in China’s network will be 280 billion yuan and DC 220 billion yuan. yuan. State Grid UHV AC will be built into a “three horizontal, three vertical and one ring network†pattern, and the north, northwest, and northeastern coal, wind, and solar power will be transported through UHV AC and DC to the Bohai Sea and southeastern regions. And the construction goals of southwest hydropower to the southeast region.
In terms of smart grids, as the basic direction for the development of the world's power grids, during the “12th Five-Year Plan†period, key technology research and development, equipment development and demonstration applications for smart grids will be mentioned at higher levels. At present, relevant companies are accelerating the formulation and improvement of intelligent standards for power systems, strengthening related platforms and infrastructure construction, and conducting pilot projects for smart grid construction in more economically developed and renewable energy agglomeration areas. To build a number of demonstration projects for distributed energy access to the power grid, start construction of microgrid pilot projects, promote the construction of distribution networks suitable for fast charging and slow charging of electric vehicles, and actively develop smart residential communities, smart building construction, and smart meter applications.
