Recently, there have been media explosions: In 2011, non-fossil energy accounted for the proportion of China’s total primary energy production and consumption, which did not rise, but dropped by approximately 8.7% and 8%, respectively, which was a decrease of approximately 0.5 percentage point from the previous year.
From this point of view, the effects of power structure adjustments have been diluted. The unpredictability of energy structure adjustment reflects the fact that China’s extensive development approach, which relied excessively on energy resources to support economic growth, has not changed significantly, and there is a long way to go to adjust the power structure.
Although the overall effect is not good, it must be pointed out that the achievement of power structure adjustment can not be ignored. According to CEC statistics, in 2011, most of China’s newly installed power generation capacity was 600,000 kilowatts and above units and 300,000 kilowatts of cogeneration units.
The proportion of clean energy in total installed capacity reached 27.5%, which was 0.9 percentage point higher than the previous year in 2011. The loop length of the power transmission line of 220 kV and above transmission lines and the capacity of public transformers increased by 7.9% and 10.5% respectively over the previous year, and the investment in the completion of power grid construction increased by 6.8% from the previous year, and the resource allocation capacity of the power grid was further improved.
The investment in thermal power continues to decline, clean power supplies focus on the quality of development
Hydropower, nuclear power, wind power, solar power, "every family has a hard time". This year, the development of clean power must first solve many problems left over by history: hydropower ecology and immigration problems, nuclear power safety issues, wind power stability issues, solar power market startup problems... CEP expects that in 2012, China will add new The power generation capacity is 85 million kilowatts, and thermal power is further reduced to 50 million kilowatts. Hydropower, nuclear power, wind power and other clean energy are about 35 million kilowatts, which is higher than the 31.53 million kilowatts in 2011. Experts estimate that by the end of 2012, China’s share of clean energy in power generation may increase by nearly 1 percentage point.
While increasing the proportion of clean energy installed capacity, improving and ensuring the quality of clean energy development will be a major theme of this year's power structure adjustment.
The social environment for hydropower development will continue to improve this year. In 2012, China's newly added hydropower installed capacity may reach 20 million kilowatts.
The prospect of nuclear power in security disputes tends to be clear. The "Nuclear Safety Plan" of the Ministry of Environmental Protection, the "Nuclear Power Safety Plan" and the "Nuclear Power Medium and Long-Term Development Adjustment Plan" drafted by the National Energy Administration, and the nuclear power company safety inspection reports have been submitted to the State Council one after another for approval. Nuclear power will wait for approval and restart, and will start again with more stringent standards.
After the stability disputes, wind power standards have gradually become more complete. During the “Twelfth Five-Year Plan†period, the first batch of wind power projects had been approved, a number of wind power standards were issued, and the State Electricity Regulatory Commission has vigorously followed up wind power and grid safety supervision. Wind power is expected to enter the standard and orderly stage in 2012. In 2012, it is estimated that about 12 million kilowatts of grid-connected wind power will be added. Solar power will become a rising star. The National Energy Administration will organize the implementation of the first batch of solar energy development plans with a scale of 3 million kilowatts during the “Twelfth Five-Year Plan†this year, which is the sum of the installed photovoltaic capacity in China.
The Ministry of Industry and Information Technology recently released the “12th Five-Year Development Plan for Solar Photovoltaic Industryâ€. The China Electric Power Union and other departments are stepping up development and will release relevant technical standards during the year, which will surely promote solar power generation as the highlight of 2012 new energy industry growth.
It can be foreseen that in 2012, it will not only be a year for the continuous increase in the installed capacity of clean energy, but also a year for the orderly development and improvement of the quality of clean energy.
Optimize grid structure to ensure clean energy output growth
It is worth noting that while the scale of clean energy installed capacity increased in 2011, the utilization hours of nuclear power and wind power equipment have decreased, and the number of hours of utilization of thermal power equipment has also been inverted. The problem of uncoordinated construction of the power grid and power supply will inevitably cause great concern in the power system.
In this regard, power grid companies have expressed that they will be more active in advancing the adjustment of power structure, eliminating high-quality generating units and clean energy. State Grid Corporation of China has proposed that it must strictly implement the national policy to eliminate backward production capacity and energy-saving emission reduction policy. Do a good job of clean energy grid connection and acceptance work. Actively carry out energy-saving power generation dispatching and power generation rights trading, and advance clean development mechanism (CDM) projects. China Southern Power Grid proposed to actively guide and promote the orderly development of new energy.
In 2012, the Hebei-East Power Transmission Project, the Kaolin Back-to-Back Expansion Project, the Xinjiang-Geermu 750-kV AC Project, and the Jinping-Su-Nan UHV DC Project were listed as key projects of the State Grid. The successful completion of these projects will further increase the ability of the grid to allocate resources across regions.
For the relatively weak "distribution network", the State Grid proposed to increase the intensity of the transformation of the low-voltage distribution network, improve the quality of operation and maintenance, and accelerate the reconstruction and upgrading of rural power projects. In 2012, the distribution network's planning, investment management and construction quality levels are expected to achieve major improvements.
The smart grid is a project that both grid companies are focusing on. State Grid proposed designing and constructing a new generation of smart substations, completing the installation of 37 million smart meter installations with high quality, promoting the construction of service networks in key cities, the Yangtze River Delta and the Bohai Rim, and exploring the commercial operation mode of smart communities. China Southern Power Grid Corporation proposed to promote the planning and construction of the "12th Five-Year Plan" Smart Grid Demonstration Zone, and put into production the Zhuhai Dong'ao Island Smart Micro Grid Project.
With the optimization of the power grid, the grid-connected problem of clean energy such as wind power, and the low utilization hours of 600,000 kilowatts of fossil-fired power units, this year will get some relief and ease, and clean and efficient power generation will be more fully utilized.
