Given the fundamental position of coal in China's energy structure, during the â€œ12th Five-Year Planâ€ period, thermal power will still be Chinaâ€™s main power source. However, energy-saving and environmental protection pressures will limit the development speed of thermal power and promote thermal power equipment manufacturers to further develop large-capacity, high-efficiency products.
In China's energy system, thermal power has been in a state of contradiction. On the one hand, thermal power has always occupied the main position of energy supply. By 2010, its proportion is still about 70%; on the other hand, energy-saving, emission reduction and environmental protection pressures require China to reduce its thermal power consumption as much as possible.
Therefore, taking into account China's energy security and energy conservation and emission reduction trends, during the "12th Five-Year Plan" period, the absolute installed capacity of thermal power will continue to grow at a low rate, but the proportion of energy in the energy structure will continue to decline.
"Twelfth Five-Year Plan" thermal power is still the main power source The National Energy Administration National Energy Conference held on January 6, 2011 stated that during the "12th Five-Year Plan" period, thermal power is still the main power source of China. According to preliminary calculations, the new construction of thermal power during the 12th Five-Year Plan period will reach 260 million to 270 million kilowatts. Among them, it is planned to start 80 million kilowatts of thermal power in 2011.
Thermal power will continue to play the role of the main power source, which is due to the basic position of coal in China's energy supply. Zhang Guobao said that in China's primary energy composition, due to the fact that the coal-dominated situation cannot be changed in the short term, China will still face the resource endowment pattern of more coal, less oil, and lack of gas in the long term. Coal will still play a fundamental role in safeguarding Chinaâ€™s energy security.
Therefore, in the "12th Five-Year Plan" period, in order to meet the rapid development of the energy demand of the economy and ensure China's energy supply security, China will continue to build thermal power projects. However, there will be changes in the growth rate of new installed capacity and construction methods.
Ren Haoning, a researcher in the energy industry of China Investment Advisors, believes that during the â€œ12th Five-Year Planâ€ period, thermal power construction will maintain a low growth rate. By 2015, thermal power installed capacity is expected to be around 900 million kilowatts.
While reducing the rate of newly installed thermal power generation, the state will also optimize the development of thermal power, reasonably control the scale of construction, and leave sufficient space for the development of hydropower, nuclear power and other renewable energy sources.
How to "leave enough space"? The â€œTwelfth Five-Year Planâ€ thermal power plan has already answered: We will vigorously build cogeneration units and gas-fired power stations, orderly build coal power stations in the west, and strictly control new and expanded coal-fired power stations in the eastern coastal areas.
At the National Energy Work Conference, Zhang Guobao stated: â€œIn the large and medium-sized cities and their surrounding areas, no new coal-fired power stations will be laid out and the power required will be solved through the western power transmission. Continue to promote the transmission of power from the west to the east and from the north to the south. Build ultra-high voltage and UHV transmission lines, transform urban and rural distribution networks, and actively promote the construction of smart grids."
Industry experts said that this means that the newly added thermal power units in the â€œTwelfth Five-Year Planâ€ are likely to be concentrated mainly in the central and western regions and will be supplied by the transmission lines to the eastern load regions; the construction of thermal power plants at load centers will become history.
Energy Saving and Emission Reduction Requirements Reduction of Thermal Power Ratio In 2010, a new record made by the thermal power industry made the industry excited: On January 5 of that year, Shanghai's largest power plant, Shanghai Waigaoqiao No. 3 Power Generation Company announced that the power plant was actually in 2009. The coal consumption for running power supply dropped to 282 g/kWh, setting a new world record of 287 g/kWh created by the company in 2008. In the same period, the average level of coal consumption for power supply in China was about 340 g/kWh.
This news can cause shock in the industry, which is caused by the enormous pressure of energy conservation and emission reduction. The Chinese government has increasingly attached importance to energy conservation and emission reduction, and has listed resource conservation and environmental protection as a basic national policy. Since the end of 2006, the Central Economic Work Conference proposed that energy saving and emission reduction should be taken as a breakthrough and an important starting point for economic structural adjustment and transformation of growth patterns. As a focal point of macroeconomic regulation and control, the importance of energy saving, emission reduction and environmental protection work has been raised to an unprecedented level. .
Thermal power is a major carbon emitter. The excessively high proportion of thermal power causes large emissions of greenhouse gases such as carbon dioxide and pollutants such as sulfur dioxide and nitrogen oxides. To achieve the goal of reducing carbon dioxide emissions per unit of GDP by 2020 from 40% to 45% in 2005, it is imperative to reduce the proportion of thermal power in China's energy structure.
On the one hand, thermal power is the main power source. On the other hand, the proportion of thermal power must be reduced. How to solve the dilemma?
From the National Energy Work Conference, the solution to the problem is to clean up and use traditional energy and accelerate the construction of new energy. The National Energy Work Conference pointed out that in promoting the clean and efficient use of traditional energy sources, large-scale coal bases and large-scale oil and gas bases should be built, and thermal power should be rationally distributed to achieve optimal development of thermal power through â€œhigh pressure and small pressureâ€ and cogeneration of heat and power.
In accelerating the development of new energy and renewable energy, we will actively develop hydropower on the premise of protecting the ecology, develop nuclear power on the basis of ensuring safety, actively develop wind power, steadily develop solar energy, and promote the development and utilization of biomass and geothermal energy. At the same time, it will also optimize the regional layout of energy development and coordinate the energy development in the eastern, central and western regions.
It is understood that during the â€œ12th Five-Year Planâ€ period, the state will promote the construction of 14 large-scale coal bases in an orderly manner, striving to achieve 90% of the total output of large-scale coal bases at the end of the â€œTwelfth Five-Year Planâ€, and large and medium-sized coal mine production capacity in the bases. Accounted for 90%.
In view of the important status of thermal power and the pressure of carbon emission reduction in China, experts predict that by the end of the â€œTwelfth Five-Year Planâ€, the proportion of thermal power will decrease, but it will still be higher than 60%. The slow development of thermal power will inevitably continue.
