CLP releases 2013 national electricity supply ...

2018-07-11

[Abstract] in 2012, the world economy continued to be sluggish and the domestic economic growth slowed down. The total energy consumption of the whole society increased by 5.5% year-on-year, and the growth rate was 6.5 percentage points down from the previous year. The third industry and urban and rural residents' electricity consumption remained two digit growth. The first industry electricity consumption was basically equal to the previous year. The growth rate of the second industry, especially the high energy consumption industry, was greatly reduced, which was the fundamental driving factor for the decline of the whole social electricity consumption growth. The utilization of hydropower equipment increased by 536 hours compared with the same period, and the use of thermal power equipment decreased by 340 hours compared to the same period of the same period. The capacity of grid connected wind power installed over 60 million KW, power generation over 100 billion kwh, wind power equipment increased by 18 hours compared with the same year, and solar power increased by more than four times. The standard coal consumption and the performance values of soot, sulphur dioxide and nitrogen oxides of thermal power units decreased compared with the previous year.

In 2013, China's economy will continue to recover steadily, with the increase in demand for electricity and electricity, which is expected to increase by 7.5%~9.0%, about 8% of the GDP, and a corresponding increase of 6.5%~8.5% for all social electricity consumption and about 7.5%. At the end of the year, it is estimated that the total capacity of the whole country power generation installed capacity is about 1 billion 230 million kilowatts, and the annual power generation equipment is used for 4700~4800 hours, of which thermal power is 5050~5150 hours, up from the previous year. In the whole year, the overall balance of power supply and demand in the whole country, the surplus of electric power in the northeast region, the surplus of electricity in the northwest region, and some provinces in East China and North China may have a small amount of power gap during the peak period.

Analysis of power supply and demand in China in 2012

(1) the growth of electricity consumption in the whole society has fallen sharply, and the amount of electricity consumption goes into the period of single digit growth according to the statistics of the national electric power industry annual Express (the same) in 2012. In 2012, the total electricity consumption of the whole country was 4 trillion and 960 billion kwh, up 5.5%, the increase of speed ratio was 6.5 percentage points down from the previous year, and the growth rate of each quarter was divided. Do not be 6.8%, 4.3%, 3.6% and 7.3%, which coincide with the trend of GDP growth in the same period. It is not only the result of the slowdown in domestic economic growth caused by the sustained downturn in the world economy and the common role of the national macroeconomic regulation and control, but also the specific economic transition period of China's economic transition in the power industry in the period of thirty years' rapid economic growth and the period of transition from the early industrialization to the middle and late stages of industrialization. Reflect.

According to the industry, the electricity consumption of the primary industry was flat in 2012. The second industry electricity consumption increased by 3.9% year-on-year, of which four high energy consumption industries, including chemical, building materials, black metal smelting and non-ferrous metal smelting, increased by 2.7%, 10.8 percentage points down from the previous year, and the contribution rate of energy consumption growth of four high energy consumption industries to the whole social electricity consumption growth (that is, four high energy consumption line) The proportion of industrial electricity growth accounted for the proportion of total social electricity growth decreased by 20.3 percentage points over the previous year, reflecting the fundamental cause of the decline in the growth rate of the second industry and the whole social electricity consumption of the four high energy consumption industries; the fourth quarter, because of the market anticipation and the replenishment of stock, the four high energy consumption line The growth of electricity consumption rose to 7.6%, and the contribution rate to the growth of whole social electricity consumption rose to 33.3%, which was obviously higher than the contribution rate of the previous three quarters (7.1%), which led to a rapid increase in the growth of the whole society. The third industry and the urban and rural residents' electricity consumption increased by 11.5% and 10.7% respectively compared with the previous year. The contribution rate to the total social electricity consumption increased by 10.3 and 12.9 percentage points respectively, which continued to play an obvious supporting role in the growth of the whole social electricity consumption in recent years.

(two) the power supply capacity continued to increase, the structure was further optimized in 2012, the capacity of the new power generation equipment was 80 million 200 thousand kilowatts, the national power generation installed at the end of the year was 1 billion 145 million KW, up 7.8%, and the investment was 746 billion 600 million yuan, a year-on-year decline of 1.9%; the full caliber generation capacity was 4 trillion and 980 billion thousand watts, the year-on-year increase of 5.2%, and the average power generation equipment Use 4572 hours for hours, 158 hours down from the same period.

At the end of the year, the whole country installed 249 million kilowatts at the end of the year, a year-on-year increase of 6.8%, the investment growth of 31.5%, the increase of electricity generation by 29.3%, and the increase of the average utilization hours of hydropower equipment by 536 hours compared with the previous year.

Grid connected wind power at the end of the year installed 60 million 830 thousand kilowatts, leaping the world's first; power generation in 100 billion 400 million kwh, for the first time over nuclear power generation; the average utilization of wind power equipment is 18 hours higher than the previous year, and the utilization rate of wind power is slightly improved, of which the distributed provinces use higher hours, rich supply and concentrated development of the northeast land. The area has declined.

Grid connected solar power installed at the end of the year was 3 million 280 thousand kilowatts, an increase of 47.8% over the same period last year, and generating capacity of 3 billion 500 million kwh, an increase of 4.1 times over the previous year.

The installed capacity of nuclear power at the end of the year was 12 million 570 thousand kilowatts, unchanged from the previous year, and generating capacity of 98 billion 200 million kwh, an increase of 12.6% over the same period last year.

The investment in thermal power continued to decline, at the end of the year 819 million KW, up 6.6%, the proportion of the national installed capacity was 0.7 percentage points lower than that of the previous year; the supply of electric coal was generally stable, the power generation increased by 0.3%, and the average utilization hour of the National thermal power equipment was 340 lower than that of the previous year.

The power supply standard of the national thermal power unit is 326 grams per kilowatt hour, the year-on-year decrease of 3 g / kwh; the proportion of the flue gas desulphurization unit to the coal and electric unit is about 90%; the capacity of the flue gas denitrification unit reached 230 million KW, the increase of 65%, and the performance value of soot, SO2 and NOx is lower than that of the previous year.

In 2012, the national cross region power supply increased by 201 billion 800 million kwh, an increase of 20.2% over the previous year, and the output power of the trans provincial province was 722 billion 200 million kwh, an increase of 14.2% over the same period last year. Among them, the power supply of the north-west
