On January 6, the National Energy Administration released the 2009 power industry operating indicators including aggregate domestic power consumption and capacity of small generator units shut down.
In 2009, aggregate domestic power consumption was characterized by a slow start, stabilizing halfway, improving month by month, and finally accelerating in growth. The aggregate power consumption was 3.643 trillion kWh, an increase of 5.96% year on year, which was higher than that in the previous year by 0.47%. The consumption in the primary industry was 94.7 billion kWh, an increase of 7.86%; that in the secondary industry amounted to 2.6993 trillion kWh, an increase of 4.15%; that in the tertiary industry was 392.1 billion kWh, an increase of 12.11%; the total power consumption by urban and rural residents was 457.1kWh, an increase of 11.87%.
The decrease in the GEAHs (Generating Equipment Availability Hours) of power generation equipment was slower. In 2009, the average GEAHs were 4527 hours in a power station of 6,000kW or above, a decrease of 212 hours year on year. In the case of hydropower, the GEAHs were 3,264 hours, a decrease of 325 hours year on year; those for thermal power were 4,839 hours, a decrease of 46 hours year on year – close to the level in the previous year; those for nuclear power were 7,914 hours, an increase of 89 hours year on year; those for wind power were 185, a decrease of 185 hours. The standard coal consumption for power supplies were 342g/kWh, a decrease of 3g/kWh year on year.
Investments in electric power construction increased steadily. In 2009, the investments in electric power infrastructure amounted to RMB755.84 billion, an increase of 19.93% year on year. The investments for power generation facilities and those for grids were 371.13 billion and 384.71 billion, increasing by 8.91% and 32.89% respectively year on year. The investment structure for power generation infrastructure appeared to undergo an adjustment: the completed investments for thermal power generation infrastructure were down 11.11% year on year, while those for nuclear power and wind power were up 74.91% and 43.9% respectively. Investments in grid infrastructure increased significantly, accounting for 50.9% of the total investments in electric power infrastructure.
The power generation structure was further optimized. In 2009, the newly added installed capacity was 89.7 million kW. At the end of 2009, the national installed capacity was 8.7407 trillion kW, an increase of 10.23% year on year. Hydropower was 1.9679 trillion kW, an increase of 14.01%, accounting for 22.51% of the total capacity or 0.74% more than at the end of 2008; thermal power amounted to 6.5205 trillion kW, an increase of 8.16%, accounting for 74.6% of the total capacity or down by 1.45% over the end of 2008.
Key projects were implemented at a faster pace. Thermal power construction developed in the direction of large capacity, high parameters, and environmental protection. At the end of 2009, the generator units each with an installed capacity of 300,000kW or above accounted for 64.46% of the total capacity of thermal power generator units. As for nuclear power, project initiation approval and construction were accelerated: Two 125,000kW nuclear power generator units at Sanmen, Zhejiang, two 125,000kW nuclear power generator units at Haiyang, Shandong, and two 175,000kW nuclear power generator units at Taishan, Guangdong were approved in 2009, whose construction started within the year; by the end of 2009, 20 nuclear power generator units were under construction, with a total capacity of 21.92 million kW. When Laxiwa Hydropower Station in Qinghai, Xiaowan Hydropower Station in Yunnan, and Pubugou Hydropower Station on the Dadu River, Sichuan were up and running and the pumped storage power stations in Hebei, Shanxi, Henan, Hunan, and Guangdong with a combined capacity of 3.55 million kW were completed, the newly added installed capacity of hydropower in China reached a high level. With the acceleration of wind power development, the installed capacity of wind power connected to the grid in Inner Mongolia exceeded 5 million kW; Jiuquan Wind Power Base in Gansu was started as the megawatt PV power generation demonstration project in China.
Small thermal power stations were shut down ahead of schedule. 2009 saw the shutdown of small thermal power stations with a combined capacity of 26.17 million kW in China. During the 11th Five-Year Plan period, small thermal power stations with a combined capacity of 60.06kW were shut down, exceeding the planned objective by 10.06kW. This meant that 69 million tons of coal could be saved each year, with 1.2 million tons of sulfur dioxide emissions and 139 million tons of carbon dioxide emissions reduced.
