China's power investment and new capacity structure is optimized.

2016-11-21 01:37

In 2009, the growth rate of electric power production and consumption rebounded nationwide; the growth rate of electric power investment increased, the structure was optimized, the new installed capacity continued to maintain a large scale, the development of non fossil energy power generation accelerated, and the power technology made important breakthroughs; the national supply capacity was sufficient, and the hourly decline rate of power generation equipment utilization was narrowed.

On the whole, the national power supply and demand is generally balanced, and individual provinces and regions have a slight surplus; the benefits of thermal power companies have improved, and the profits of power grid companies have declined, but there is no stable market guarantee mechanism for industry benefits. It is expected that the national power supply and demand will maintain an overall balance in 2010. Surplus situation. But at the same time, there will be some areas, parts of the region's power supply and demand is tight, and there is a certain amount of power gap.

Data

Electricity investment and new capacity structure to optimize the whole society's electricity consumption increased by 5.96

National Power Supply New Production Capacity 89.7 million kW

In 2009, the structure of power investment and new capacity continued to be optimized, and the supply capacity was sufficient. According to statistics, the national investment in power construction was 755.8 billion billion yuan, up 19.93 percent year on year. Among them, power investment was 371.1 billion billion yuan, accounting for 49.10 percent of the total power investment, an increase of 8.92 percent over the same period last year, an increase of 3.31 percentage points over the previous year, and power grid investment was 384.7 billion billion yuan, an increase of 32.89 percent over the previous year, accounting for 50.90 percent of the total power investment. Investment in power infrastructure continued to accelerate structural adjustment. The completed investment in hydropower, nuclear power, and wind power infrastructure increased by 2.33, 74.91, and 43.90 year-on-year, respectively, and the completed investment in thermal power infrastructure decreased by 11.11 year-on-year.

In 2009, the electricity consumption of the whole society 3643 billion kilowatt hours, an increase of 5.96 percent over the same period last year, and the growth rate was 0.47 percentage points higher than that of the previous year. Monthly electricity consumption accelerated month by month, and in June, the electricity consumption of the whole society showed a real positive growth for the first time since October 2008. In each quarter of 2009, the electricity consumption of the whole society was 781 billion kilowatt-hours, 871.6 billion kilowatt-hours, 1011 billion kilowatt-hours and 979.5 billion kilowatt-hours, up -4.02%, -0.59%, 7.97% and 20.72% respectively, and the growth rate of electricity consumption rebounded for four consecutive quarters.

In 2009, the national power production capacity increased by 89.7 million kilowatts, including 19.89 million kilowatts of hydropower, 60.83 million kilowatts of thermal power, 8.97 million kilowatts of wind power and 18700 kilowatts of solar energy. The new structure continues to be optimized, the scale of renewable energy production is gradually expanded, and the number of wind power units is doubled. Ten new million kilowatt thermal power units have been put into operation, with the proportion of new units with a single unit capacity of 600000 kilowatts and above reaching 55.03 percent. Units below 300000 kilowatts (accounting for 7.8 percent of the new thermal power units) are basically cogeneration units and comprehensive resource utilization units. Nuclear power starts with a scale of 8.5 million kilowatts and under construction is 21.8 million kilowatts, ranked first in the world.

The "big pressure small" continued to advance, the annual shutdown of small thermal power units with a capacity of 26.17 million kilowatts.

By the end of 2009, the capacity of full-caliber power generation equipment nationwide was 874.07 million kilowatts, a net increase of 81.3 million kilowatts over the end of the previous year, an increase of 10.23 percent over the same period last year. Among them, hydropower 196.79 million kilowatts, a year-on-year increase of 14.01; thermal power 652.05 million kilowatts, a year-on-year increase of 8.16; nuclear power 9.08 million kilowatts; grid-connected wind power 16.13 million kilowatts, a year-on-year increase of 92.26. The structure of generating units has been gradually optimized, and the proportion of non-fossil energy has increased. The proportion of thermal power equipment capacity in the total capacity decreased by 1.45 percentage points over the previous year; the proportion of hydropower and wind power increased by 0.74 and 0.78 percentage points respectively; there were no new nuclear power units put into operation, and the proportion decreased slightly. The utilization hours of power generation equipment nationwide decreased slightly, and the decline narrowed significantly. In 2009, the utilization hours of power generation equipment in power plants of 6000 kW and above were 4527 hours, 121 hours lower than that of the previous year, and 251 hours lower than that of the previous year.

National interconnection continues to promote the continuous expansion of power grid scale

According to statistics, at the end of 2009, the length of transmission line circuits of 35 kV and above in the national power grid was 1.254 million kilometers, an increase of 7.23 percent over the same period last year, and the capacity of public transformer equipment of 35 kV and above was 2.82 billion kVA, an increase of 16.03 percent over the same period last year.

In 2009, the cumulative output of electricity among provinces across the country was 524.7 billion kilowatt-hours, an increase of 17.93 percent over the same period last year, an increase of 1.81 percentage points over the previous year, and maintained rapid growth in all months of the year. The output of electricity in major energy-exporting provinces maintained rapid growth.

In addition, the exchange of electricity with neighboring countries and regions has increased, with total electricity imports and exports of 24.1 billion kWh, an increase of 18.01 per cent over the same period last year, of which 6.1 billion kWh of imported electricity, an increase of 72.06 per cent over the same period last year, and 18 billion kWh of exported electricity, an increase of 6.62 per cent over the same period last year.
