Statistics released recently by the China Electricity Council show that in 2007, China’s power generation capacity reached a new historical high, with the installed power capacity exceeding 700 million kilowatts. By the end of 2007, the country’s new installed capacity had reached 100.09 million kilowatts, bringing the total to 713.29 million kilowatts. Among them, hydropower capacity increased by 13.065 million kilowatts, while thermal power capacity increased by 81.5835 million kilowatts. At the same time, 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 indicates that China has successfully mastered the world’s advanced thermal power generation technology, and the power industry has entered the \"ultra-supercritical\" era. In addition, the development of China’s power grid has progressed rapidly, with an increase of 41,500 kilometers in the length of 220 kV and higher voltage transmission lines, and an increase in the capacity of 220 kV and higher voltage transformer equipment amounting to 18,848 million kVA. Among them, 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 western power-to-eastern power transmission route in the south. In 2007, China stepped up efforts to adjust its power source structure, and the construction of hydropower projects 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, 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 was fully launched, with the Xiluodu Power Station completing its cofferdam closure on November 8, 2007 ； 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. At the same time, breakthroughs were made in wind power generation, with the Inner Mongolia Autonomous Region becoming the first province in China to have a wind power installation capacity exceeding one million kilowatts. On November 8, 2007, 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 steadily.
