The 30 years of reform and opening up are the 30 years of China's electric power industry's transformation and development. It has broken down the institutional mechanisms to eliminate industry monopolies and explored the path of marketization. The rapid increase in installed capacity has solved the shortage of power and continued optimization of the power supply structure and the continuous improvement of clean energy. Power generation ratio... China's power industry has overcome many contradictions and difficulties in the layout structure, institutional mechanisms, and market environment, and has achieved accelerated development in the pain of transition.
Since the financial crisis, the rapid economic recovery in our country has attracted worldwide attention. As the basic industry of the national economy, the power industry also achieved a recovery growth in 2010, power demand and consumption gradually recovered, power generation installed capacity continued to maintain rapid growth, power transmission and transformation capabilities further improved, the country is in a new round of economic and power development The initial stage of the cycle. According to the latest data released by the China Electricity Council (hereinafter referred to as “CECâ€), from January to August this year, China’s power infrastructure construction has completed an investment of RMB 196.6 billion, of which hydropower is RMB 40.2 billion, thermal power is RMB 73.6 billion, and nuclear power is 359 Billion yuan, wind power 46 billion yuan. The country's new power production capacity (formally put into operation) was 47.13 million kilowatts, of which hydropower was 9.5 million kilowatts, thermal power was 32.91 million kilowatts, and wind power was 4.54 million kilowatts. The investment in basic power grid construction has reached 169.3 billion yuan, and the new 220 kilovolt and above power transmission capacity of the power grid construction has reached 125.99 million kVA with a length of 19,613 kilometers.
As a source of powerful economic development and social progress, what kind of development trend will China's electric power industry present in the coming “12th Five-Year Plan†period? What are the development opportunities and challenges for power equipment manufacturers? With these questions, Wang Zhixuan, secretary-general of the China Electricity Council, was interviewed to conduct an overall analysis of the current development of the power industry.
Reporter: The reform and opening up has provided a powerful impetus for the rapid development of the electric power industry. The past 30 years have been an important component of China's economic system reform, and it is also the main stage for China's power industry to continuously improve the quality of development and realize leapfrog development. Could you brief us on the basic development of China's power industry after 30 years of development?
Wang Zhixuan: Since the reform and opening up, the steady development of the electric power industry has provided strong energy support for the continuous and rapid growth of China's national economy and the continuous improvement of people’s living standards. In the early days of the establishment of new China, China’s installed capacity for power generation was only 1.85 million kilowatts. After 30 years of development, the development law of China's power industry and the country’s macro economy has shown a mutual promotion process. The scale of power generation installed capacity has increased from 57.12 million kilowatts in 1978 to 8.741 million kilowatts in 2009, which has increased cumulatively in 31 years. 14 times, the installed capacity of power generation has ranked second in the world for 14 consecutive years.
Since April 2009, the country’s installed capacity for electric power exceeded 800 million kilowatts, and China’s installed capacity for electric power has once again reached a new level in 2010. In mid-2010, China’s electric power installed capacity exceeded 900 million kilowatts, and it was determined that China’s Guangdong Nuclear Power Group Co., Ltd. Ling Ao Nuclear Power Station Phase II Unit 1 was the breakthrough 900 million kilowatts of the flagship unit, the Chinese power industry, especially clean energy and its The development of the corresponding power grid construction has also opened a new page.
China's power generation installed capacity has exceeded 900 million kilowatts, which is an important milestone in the history of China's electric power development, and marks a new leap in the development of China's power industry, and is also a concentrated expression of China’s growing comprehensive national strength.
Reporter: I believe that the leap-forward development of China's power industry is not only reflected in the breakthrough in installed capacity, but also reflected in China's large-scale grid construction. Previously, the State Grid Corporation of China stated that by 2020, the national grid will be built with the "Samhwa" UHV synchronous power grid as the center, the northeast UHV power grid and the northwest 750 kilovolt power grid as the delivery end, linking major coal-fired power bases, Large hydropower bases, large nuclear power bases, large renewable energy bases, and strong smart grids with coordinated development of power grids at all levels.
Wang Zhixuan: Indeed, while the steady development of power installations, China’s power grid construction has also made remarkable achievements. According to statistics, as of the end of 2009, the length of the national 220 kV and above transmission line circuits reached 399,400 km, an increase of 11.29% over the previous year; the capacity of 220 kV and above substation equipment was 1.762 billion kVA, an increase over the previous year. 19.40%, of which the cross-regional, inter-provincial, and provincial backbone power grids with 500 kV and above AC and DC voltage levels grew rapidly, and their loop length and substation capacity increased by 16.64% and 25.97% respectively over the previous year.
It should be noted that at present, the scale of China's power grid has exceeded the United States, ranking first in the world. In particular, the Jindongnan-Nanyang-Jingmen 1000kV UHV AC pilot demonstration project was formally put into operation, the ±800 kV Xiangjiaba-Shanghai UHV DC demonstration project was put into operation, and the ±800 kV Yunnan-Guangdong UHV DC project went into operation. In operation, the highest DC and AC voltage levels in China are increased from ±500 kV and 750 kV to ±800 kV and 1000 kV, respectively, and the long-distance large-capacity transmission capacity is enhanced, providing a higher level of optimization for the country's resource allocation. network platform.
Moreover, the full-scale construction of the Qinghai-Tibet network project in July this year and the Xinjiang and Northwest Power Grid interconnection projects are scheduled to be put into operation in November, which also marks the in-depth implementation of China's western development strategy, strengthening of infrastructure construction of power grids in the western region, and intensification of “West-to-East Electricity Transmissionâ€. "The scale of the passage has taken another important step.
Reporter: In recent years, as China's industrialization, accelerated urbanization, and economic globalization continue to deepen, China’s energy security, environmental protection, and the response to climate change issues have become increasingly severe and prominent, and for this reason China has also stepped up efforts to optimize energy structure adjustments. Can you please tell us about the progress made by China's power industry in this area?
Wang Zhixuan: Since the new century, especially the 11th Five-Year Plan, China’s electric power industry has achieved the goals of high efficiency, environmental protection, safety, energy conservation, economy, and sustainable development under the general requirement of adhering to the scientific development concept and building a conservation-minded society. A gratifying result.
The power supply structure continues to be optimized, and the proportion of clean energy generation continues to increase. The thermal power unit continues to develop in the direction of large capacity, high parameters, and environmental protection. As of the end of August 2010, 27 million megawatts of ultra-supercritical units have been put into operation in the country, which is the largest country in the world with millions of kilowatts of ultra-supercritical units; the proportion of 300,000 kilowatts and above of thermal power generators has accounted for the proportion of all thermal power units. The 42.67% in 2000 increased to 69.43% in 2009.
In terms of clean energy development, the country’s installed capacity for hydropower has exceeded 200 million kilowatts this year, and it has become the world’s largest country with the largest installed capacity for hydropower. At the end of 2009, the country's nuclear power installed capacity was 9.08 million kilowatts, ranking the ninth in the world. The construction scale of nuclear power under construction was 21.92 million kilowatts. The construction scale under construction ranks first in the world. As of August 2010, the installed capacity of grid-connected wind power in the country was 22.94 million kilowatts. , Grid-connected wind power installed capacity and power generation doubled for four consecutive years, and the proportion of non-fossil energy power generation installed capacity increased year by year.
It can be seen that this nuclear power unit is an iconic unit with a capacity of 900 million kilowatts. The significance of this is that it shows that China's clean and renewable energy sources are in a healthy development, reflecting the enthusiasm and achievements of the entire power industry in implementing the scientific concept of development.
Reporter: However, overall, the structural problems in the power industry still exist. Although China's power generation and supply capacity is relatively sufficient after the financial crisis, structural imbalances in various regions are also more obvious. In your opinion, what key issues need to be resolved in China's power industry in the next phase?
Wang Zhixuan: Energy and power have a very important strategic position in the national economy. At this stage, China is in a critical period of building a well-to-do society in an all-round way, and there is still great demand for energy. At the same time as rapid development, we should also see that China has a large population, low per capita electricity consumption, and a large space for growth in electricity demand. However, China's energy resources and consumption distribution are in a reverse distribution, and the ability to optimize the allocation of energy in a wide range is insufficient. Objectively, it is necessary to speed up the transformation of the power development mode, give full play to the important role of modern power grids in optimizing the allocation of energy resources on a large scale, large-scale and high-efficiency, serving the country’s macro-control, promoting the annual development and utilization of renewable energy, and optimizing the energy structure. Layout to meet the needs of economic and social development.
At the same time, it is necessary to accelerate the construction of UHV AC/DC follow-up projects, build a strong main grid, promote the intensive development of large-scale energy bases and the efficient use of clean energy, and promote the coordinated development of power grids, power supply bases, transmission channels, and voltage level grids. Accelerate the advancement of intelligent development of the power system.
Reporter: 2010 is the year of the "Eleventh Five-Year Plan". Our country is about to enter the "Twelfth Five-Year" period. The current "12th Five-Year Plan" is also being actively formulated. Prior to this, China Electric Power also organized the preparation work for the 12th Five-Year Plan of the power industry. Would you please briefly introduce the progress of the planning and formulation?
Wang Zhixuan: As a federation of the electric power industry, CEC is very concerned about the government's related issues in power planning. At the same time, CEC has also organized related companies and experts to study and formulate the “12th Five-Year Plan†for the power industry. As an association organization, planning research must be considered from the angle of industry development and from the perspective of the development of power companies. It is hoped that in this two perspectives, planning can provide advice to the government and reflect industry opinions so that the government can formulate The "12th Five-Year Plan" can take into account the interests of the power industry and enterprises.
The organization of the “12th Five-Year Plan†of the power industry is a major decision made by the 5th Council of the CEC. Since CETD started this work in mid-March, it has set up an industry development planning department and planning preparation leading group, working group and preparation expert group. The first draft of the 12th Five-Year Plan for the electric power industry has been completed and is currently being discussed internally.
As for the key issues that the plan will focus on, I think we need to focus on the development of the industry. Although China's power industry has made considerable progress and its installed capacity has exceeded 900 million kilowatts, China is at a critical stage of a period of rapid development and the construction of a well-to-do society in an all-round way. In terms of its own development, the power industry needs to be rapidly developed. . Moreover, it is not difficult to see in comparison with the development of the power industry in developed countries that China is far from reaching the installed capacity and average electricity consumption of developed countries when they complete the industrialization phase. China’s power industry is even There is also a need to accelerate development in 2020, so this phase should focus on the speed and scale of development.
Second, China's power industry should also pay attention to the quality of development. Due to the constraints of resource endowments, the current status of coal-based energy use in China is difficult to change in a short period of time. Transforming the development mode of the power industry, achieving the cleanliness of development of coal and electricity and the goal of non-fossil energy accounting for 15% of primary energy in 2020, and reducing the carbon dioxide emissions per unit of GDP (GDP) by 40% to 45% in 2005 The development of China's power industry has put forward higher requirements. Therefore, in the planning, we will also pay great attention to the clean utilization of coal and the proportion of renewable energy power generation. We hope to promote the construction of large-scale hydropower during the “Twelfth Five-Year Plan†period. As well as promoting the construction of wind power and solar energy more actively and steadily.
Reporter: Regarding the development of hydropower, the "2009 National Electric Power Industry Statistics" released by the China United Electric Power Association once pointed out that hydropower development in recent years has almost stagnated due to restrictions on the ecological environment and immigration. In addition, during the “Eleventh Five-Year Plan†period, China’s hydropower development has largely lagged behind its planning goals. During the “Eleventh Five-Year Plan†period, originally planned hydropower started at about 70 million kilowatts, while the actual amount started was only 20 million kilowatts. In response to this, there have been different voices in the media. It is believed that in some key regions, China’s hydropower development level is already approaching saturation. How do you view this? What do you think is appropriate for the development of hydropower in China?
Wang Zhixuan: According to the data, the hydropower capacity approved in 2007, 2008, and 2009 was only 2.34 million kw, 7.24 million kw, and 7.37 million kw respectively, which is far less than the scale of production in recent years. As a result, the construction scale of hydropower under construction is rapidly shrinking year by year. At the end of 2009, there were only 67.25 million kilowatts.
Regarding the reasonable degree of hydropower development in China, the Chinese government has also made great efforts to carry out census. It should be said that it is generally accepted by all and is also the status of China's hydropower resources released by the country to the world as follows: the theoretical reserves of hydraulic resources and technologically exploitable installed capacity. Capacity and economically exploitable installed capacity were 690 million kilowatts, 540 million kilowatts and 402 million kilowatts, respectively. However, China’s current hydropower installed capacity is 200 million kilowatts. Even if compared with the economically exploitable capacity, there is still a large gap between China’s hydropower development, and the development of hydropower can help China complete the reduction of the world that I mentioned just now. The commitment is significant.
Reporter: In view of the above situation, what do you think is the challenge for equipment companies?
Wang Zhixuan: I think the biggest challenge at this stage is low-carbon technology. At present, China's conventional pollutant control technology is equal to the world level. This is not only a matter of the efficiency of the core equipment, including pollution control equipment, transportation and packaging environment, because the final carbon footprint is to calculate the general ledger. With increasing demands for reducing CO2 emissions and mitigating climate change, how to further increase equipment efficiency also includes whether auxiliary machinery can be more energy-efficient, can maximize the amount of power generated per unit, and ultimately convert CO2 emissions. The minimum or will be the biggest challenge faced by equipment companies. This requires equipment manufacturers to make great efforts at every very small point.
