Thread Content

In 2007, the power sector across the country continued to experience steady, rapid and healthy development, with an overall balance in supply and demand. Significant progress was made in energy conservation and consumption reduction: electricity generation increased by 14.44%, while electricity consumption rose by 14.42%. That year, the national power industry maintained its trend of steady, rapid and healthy growth; the overall supply and demand situation remained balanced, and notable achievements were made in energy conservation and emission reduction, with the annual target for shutting down small-scale power plants being exceeded. In 2007, electricity infrastructure development continued at a rapid pace; power generation capacity reached new historical highs, and grid construction advanced swiftly. Following the breakthrough of 600 million kilowatts in the country’s total power generation capacity at the end of 2006, that capacity reached a new level within just one year, exceeding 700 million kilowatts. At the same time, with the successive commissioning of seven 1-million-kilowatt ultra-supercritical units at Huaneng Yuhuan Power Plant, Huadian Zouxian Power Plant, and Guodian Taizhou Power Plant, it indicates that China has successfully mastered the world’s advanced coal-fired power generation technology, and the power industry has entered the \"ultra-supercritical\" era. In terms of power grid construction, the Sichuan-Shanghai ±800 kV UHV DC transmission demonstration project has commenced construction ； The Three Gorges power transmission and transformation project has been fully completed and passed the **acceptance inspection ； The second Guigang-Guangzhou DC transmission project has been put into operation, adding 1.5 million kilovolts to the transmission capacity of the southern route for sending electricity from the west to the east. By the end of 2007, the total installed power generation capacity across the country reached 713.29 million kilowatts, an increase of 14.36% on a year-on-year basis. Among them, hydroelectric power reached 145.26 million kilowatts, accounting for about 20.36% of the total capacity, with a year-on-year increase of 11.49% ； Thermal power capacity reached 554.42 million kilowatts, accounting for about 77.73% of the total capacity, with a year-on-year increase of 14.59% ； The share of hydro and thermal power in the total capacity decreased by 0.53 percentage points, while that of thermal power increased by 0.16 percentage points on a year-on-year basis. By region, the provinces with a year-on-year growth rate of power generation capacity exceeding 30% are: Guangxi (48.6%), Anhui (39.8%), and Inner Mongolia (38.9%).

Among them, hydroelectric power generation amounted to 486.7 billion kWh, accounting for about 14.95% of the total power generated, with a year-on-year increase of 17.61% ； Thermal power generation amounted to 2,698 billion kWh, accounting for about 82.86% of total power generation, with a year-on-year increase of 13.82% ； Nuclear power generated 62.6 billion kWh, accounting for about 1.92% of the total electricity generation, with a year-on-year increase of 14.05%. By region, the provinces with a year-on-year increase in power generation of over 20% were, in order: Guangxi (29.4%), Inner Mongolia (28.6%), Fujian (26.7%), Yunnan (22.2%), Chongqing (21.0%), and Hunan (20.3%). With a large number of power generation projects coming online one after another, the power supply and demand situation has further eased; overall, supply and demand across the country are basically in balance, and the operating hours of power generation equipment have continued to decline significantly. In 2007, the average annual equipment utilization hours for power plants across the country with a capacity of 6,000 kilowatts or more was 5,011 hours, a decrease of 187 hours compared to the previous year. Among them, the operating hours of hydropower equipment were 3,532 hours, an increase of 139 hours compared with the previous year ； The utilization hours of thermal power equipment were 5,316 hours, a decrease of 296 hours compared to the previous year ； The utilization hours of nuclear power equipment were 7,737 hours, a decrease of 69 hours compared to the previous year. In 2007, the country stepped up efforts to adjust its power source structure, and progress in hydropower development accelerated; 21 units at the Three Gorges Dam had been put into operation, giving it a power generation capacity of 14.8 million kilowatts. A number of large-scale hydropower stations, such as Longtan, Xiaowan, Goupitan, Pubugou, Jinping, Laxiwa, Xiangjiaba, and Xiluodu, have successively begun construction, with some of these projects already having parts of their facilities put into operation to generate electricity ； The development of hydropower projects on the Jinsha River has been fully launched, with the Xiluodu Power Station completing its cofferdam construction on November 8th ； In terms of nuclear power, with the commissioning of two nuclear reactors at the Tianwan Nuclear Power Plant, the country’s total nuclear power capacity has reached 8.85 million kilowatts, and the Hongyanhe Nuclear Power Project has already begun operations ； Breakthrough progress has been made in wind power generation; the wind power capacity of China Guodian Group and China Datang Group has each exceeded 10 million kilowatts. Inner Mongolia Autonomous Region has become the first province in the country to reach a wind power capacity of over 10 million kilowatts. On November 8, China’s first offshore wind power station was successfully put into operation in the Bohai Sea oil field, marking the beginning of the country’s effective utilization of offshore wind energy ； A number of biomass power plants have been built and put into operation, while photovoltaic power generation and coalbed methane development are advancing actively. Initial results have been achieved in energy conservation and emission reduction efforts. A total of 14.38 million kilowatts of small-scale thermal power plants were shut down throughout the year. In 2007, the coal consumption per unit of electricity generated nationwide was 357 grams/kWh, which was 10 grams/kWh less than in 2006 ； The loss rate of power grid transmission lines decreased by 0.19 percentage points compared to last year, falling to 6.85%. In 2007, the total electricity consumption across the country reached 3,245.8 billion kWh, an increase of 14.42% on a year-on-year basis; this growth rate was 0.26 percentage points higher than that in 2006. Among them, the electricity consumption in the primary industry was 86 billion kWh, a year-on-year increase of 5.19% ； The electricity consumption in the secondary industry was 2,484.7 billion kWh, representing a year-on-year increase of 15.66%. Among this, electricity consumption in light industry and heavy industry was 450.2 billion kWh and 2,006.4 billion kWh respectively, with year-on-year increases of 9.81% and 17.34%. The growth rates in light industry and heavy industry decreased by 0.78 percentage points and increased by 1.72 percentage points respectively compared to 2006 ； The electricity consumption in the tertiary sector was 316.7 billion kWh, representing a year-on-year increase of 12.08% ； The electricity consumption for residential and urban use was 358.4 billion kWh, an increase of 10.55% on a year-on-year basis. In terms of power infrastructure development and investment, in 2007 the country invested a total of 549.29 billion yuan in power infrastructure projects, of which 304.15 billion yuan was spent on power generation facilities and 245.14 billion yuan on power grid construction. In 2007, the new power generation capacity added to the national infrastructure was 100.09 million kilowatts, of which 13.065 million kilowatts came from hydropower, 81.5835 million kilowatts from thermal power, and 2.9617 million kilowatts from wind power ； The length of transmission lines of 220 kV and above increased by 41,500 kilometers, while the capacity of substation equipment of 220 kV and above increased by 18,848 million kVA. In 2007, under the correct leadership of **** and the State Council, through the consolidation of large-scale enterprises at the expense of smaller ones, the adjustment and optimization of the production structure, increased efforts to reduce energy consumption and emissions, as well as the joint efforts of the power industry workers, the national power industry continued to develop rapidly and steadily. This provided a solid foundation for the sound and rapid development of the national economy and society in 2008, as well as for achieving the goals of macroeconomic regulation.
