The first draft of the 12th Five-Year Plan for the power industry has been formed. The newspaper was informed that the "Twelfth Five-Year Plan Report of the Power Industry" had completed the expert discussion at the end of October, and the next step would be to report the wholesale cloth after the repair.
According to relevant sources, the 12th Five-Year Plan will focus on the transformation of power development mode, and will focus on three major directions: power supply structure, power grid construction and power reform. Among them, Tibet will be connected in 2012. At that time, the power network will cover the whole country. At the same time, the proportion of power generation and installed capacity of coal-fired power will drop by about 6% at the end of the 12th Five-Year Plan. Clean energy will further optimize the power supply structure.
Coal power proportion decreased by 6%
According to relevant sources of the China Electricity Council, the overall idea of ​​the plan is “big market, big goal, big planâ€, focusing on market demand, power supply optimization, power grid layout, technological innovation, planning economy and power development policy. In addition, energy conservation and emission reduction, electricity price mechanism, wind power scale, and nuclear power development model are also involved.
Compared with the 11th Five-Year Plan, the focus is on the structure of power development, power industry investment and financing, renewable energy development, electricity price reform, environmental protection and resource conservation, energy conservation, comprehensive balance of coal and electricity transportation, and rural power reform and development. Different issues, the 12th Five-Year Plan will focus on the focus on the transformation of power development mode, and mainly focus on the three major directions of power supply structure, power grid construction and power reform.
According to relevant sources of the State Grid Energy Research Institute, the electricity consumption of the whole society will continue to increase during the 12th Five-Year Plan period, but it will decrease compared with the average annual growth rate during the 11th Five-Year Plan period. By 2015, the national total electricity consumption will reach 54,200. From -6 to 32.32 trillion kWh, the average annual growth rate is 6%-8.8%. By 2020, the total electricity consumption will reach 6.61 trillion to 8.51 trillion kWh, with an average annual growth rate of 4%-6.1%.
“The total growth rate of electricity consumption will slow down, but the total amount will still increase. Therefore, it is necessary to optimize the power supply structure to digest the coal consumption on the power generation side. Otherwise, it will not be able to complete the 2020 non-fossil energy ratio by 15% and reduce emissions by 2020. %-45% of the target." Power analyst Lu Yang told this reporter.
However, the reporter saw from a special research report of the above plan that during the “Twelfth Five-Year Plan†period, China’s power supply structure is still dominated by coal-fired thermal power, which requires optimization of power supply structure by improving hydropower, nuclear power and non-water renewable. The proportion of installed energy and power generation of clean energy such as energy, while reducing the proportion of coal-fired power, is optimized.
According to the plan, by 2015, the proportion of installed clean energy will increase from 24% in 2009 to 30.9% in 2015 and 34.9% in 2020. The proportion of power generation will also rise from 18.8% in 2009 to 23.7% in 2015. And 27.6% in 2020.
At the same time, the proportion of installed capacity and power generation of coal power will drop by about 6%. This is also consistent with the increase in the proportion of primary energy consumption of coal during the “Twelfth Five-Year Plan†period from more than 70% in 2009 to around 63%.
According to the relevant plans of the National Energy Administration, during the “Twelfth Five-Year Plan†period, the total coal consumption will be controlled in the eastern region, and the coal-electricity development will be strictly controlled for the Bohai Rim, the Yangtze River Delta, the Pearl River Delta and parts of the Northeast. Considering the construction of power plants that support power supply construction and consume imported coal, the construction of power plants in the east will be dominated by nuclear power and gas-fired power plants.
Power grid construction: to achieve national networking
According to the forecast of the State Grid Energy Research Institute, the maximum load of the whole society will reach 990 million kilowatts by 2015, and the average annual growth rate will be 8.5% during the “12th Five-Year Plan†period. The maximum load growth rate is faster than the power consumption growth rate. Continue to increase. Among them, the eastern part is still the national load center. By 2015, the electricity consumption in the Beijing-Tianjin-Hebei, China-Middle East and East China regions will account for 55.32% of the national electricity consumption.
Increased load has proposed safe and stable operation and higher system peak shaving requirements. The reporter saw from the planned special report that in response to the increase in power load, during the 12th Five-Year Plan period, the system will be adjusted by accelerating the construction of smart grids, cross-provincial cross-region power grids, and increasing the installed capacity of pumped storage.
Shu Yinyu, deputy general manager of the State Grid, said that during the "Twelfth Five-Year Plan" period, the State Grid will implement the "one special four major" strategy to build a strong smart grid. "One special" is the development of UHV, and the "Four Big" is to realize the intensive development of large coal power, large hydropower, large nuclear power, large-scale renewable energy and efficient power transmission through the development of UHV.
"especially to develop UHV AC transmission technology, wind and light storage technology, smart grid technology, flexible DC transmission technology, UHV DC transmission technology, large-capacity energy storage technology, new energy grid-connected control technology, distributed energy and micro-grid Technology, etc." Shu Yin said.
Not only that, but the randomness and intermittentness of wind power and solar power generation output, in order to ensure the normal operation of power peaking, during the 12th Five-Year Plan period, wind power will be increased by increasing the proportion of wind and fire combined transportation and establishing a wind and light storage center. And the ability to absorb light.
Bai Jianhua, director of the Energy Strategy and Planning Institute of the State Grid Energy Research Institute, believes that “considering the thermal power peaking depth does not exceed 50%, the transmission curve is controlled at 90% during the trough, and the ratio of wind power and thermal power to the wind power base is 1:2. Suitable."
According to the planning report, by 2015, more than half of the country's wind power needs to be transported from remote areas such as Sanbei through inter-provincial and inter-regional power grids. Cross-provincial and cross-regional power grid construction has become one of the planning priorities of the “Twelfth Five-Year Planâ€.
According to the reporter, the national power network will be completed during the "Twelfth Five-Year Plan" period. By 2012, with the completion of the construction of the 750 kV/±400 kV AC-DC network project in Qinghai-Tibet, the six major power grids in the south, Central China, East China, Northwest China, Northeast China and North China will cover all provinces and cities in the Mainland.
According to relevant sources, the 12th Five-Year Plan will focus on the transformation of power development mode, and will focus on three major directions: power supply structure, power grid construction and power reform. Among them, Tibet will be connected in 2012. At that time, the power network will cover the whole country.
