Zhou Yongkang, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee and also secretary of the Committee of Political and Legislative Affairs of the CPC Central Committee, announced the commencement of two power transmission projects in Mongolian Autonomous Prefecture of Bayingolin, northwest China's Xinjiang Uygur Autonomous Region, May 13, 2012. The construction of the two projects, the Southern Hami-Zhengzhou ±800kV UHVDC Transmission Project, and the Second Xinjiang-Northwest Main Grid 750kV HVDC Transmission Line marked an essential step ahead in exporting electricity in Xinjiang.

Liu Zhenya spoke at the ceremony at the main venue.

The groundbreaking ceremony took place at the main venue in Xinjiang Bachuan Electric Power Co. and the sub-venues in Xinjiang Hami Convertor Station, Qinghai Qaidam Convertor Station, Gansu Shazhou Convertor Station, and Henan Zhengzhou Converter Station simultaneously.

Party Secretary of the Xinjiang Autonomous Region Zhang Chunxian, Chairman of the Xinjiang Uyghur Autonomous Region Nur Bekri, SASAC Chairman Wang Yong, Deputy Secretary of the Party Committee of the Xinjiang Uygur Autonomous Region Che Jun, and leaders from the Organization Department of the Central Committee of the CPC, the Central Propaganda Department, the United Front Work Department of CPC Central Committee, the Committee of Political Science and Law under the CPC Central Committee, the Ministry of Education, the Ministry of Industry and Information Technology, the Ministry of Public Security, the Ministry of Finance, the Ministry of Human Resources and Social Security, the Ministry of Housing and Urban-Rural Development, the Ministry of Commerce, and the National Energy Administration attended the ceremony at the main venue. NDRC deputy director Mr. Du Ying read out the approval document. Vice Governor of Qinghai Province Xu Fushun, Vice Governor of Gansu Province Yu Haiyan, and Vice Governor of Henan Province Zhang Dawei presented at the sub-venues. SGCC President Liu Zhenya attended the ceremony at the main venue and delivered a speech.

The Southern Hami-Zhengzhou ±800kV UHVDC Transmission Project is the first UHV project for the Northwest China Grid Co. Ltd. The 2,210-km-long line goes through the vast region of Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, and Henan. It costs 23.4 billion yuan, and is designed to have a transmission capacity of 8 GW upon completion in 2014, setting up a new world record. The second 750kV HVDC transmission line which links Xinjiang with the main grid of the Northwest China Grid Co. Ltd.is a major component of the 750kV main grid in Northwest China. With an investment of 9.56 billion yuan, the 2,180-km-long line waves its way through Xinjiang, Gansu and Qinghai and will be put into operation in September 2013.

Both projects possess important strategic significance and political influence as the key projects to implement the central government's strategy, serve China's Western Development Program, and transmit the electricity from Xinjiang to the rest parts of the country. They are green projects combining traditional energy and clean energy to promote the harmonious development of energy, economy and environment. What's more, these two projects can improve Xinjiang's self-developing capabilities and enhance coordinated regional economic development. Upon completion, they will occupy a transmission capacity of 10 GW and become the Silk Road of Electricity to connect the western frontier with the central plains with greatly enhanced optimal allocation in a wide range. By then, coal will be transported by air cargo and electricity will be available throughout the country. A new pattern will come into being. As for their environmental benefits, take the Southern Hami-Zhengzhou ±800kV UHVDC Transmission Project as an example, after the project is constructed, it can transmit power of 48 TWh to central China every year, equivalent to 22.1 million tons of coal, reducing 317 thousand tons of sulfur dioxide emission and 267 thousand tons of nitrogen oxides emission. It can effectively ease the pressure of air pollution, and save a lot of land resources.

Liu Zhenya required the two projects to be safe, reliable, innovative, economical, and environmentally friendly projects with world-class quality. He said these two projects had great significance and far-reaching impact. Besides, complex geological conditions, harsh climate, and difficult construction environment have been a great challenge for these two projects. SGCC will follow the central government's deployment, play a leading role as a central SOE, and promote the project construction. In the next step, SGCC will work closely with the local governments along the construction line, together with all construction organizations and workers to pursue excellence, innovate, tackle down difficulties, realize the construction goal with high standard, quality and efficiency, complete the channel as soon as possible, and write a new chapter for the development of the power grid in Western China and for ethnic harmony.

SGCC EVP Zhen Baosen presided over the ceremony at the main venue while SGCC EVP Shuai Junqing attended the event at the sub-venue in Henan.

It is reported that SGCC will invest over 130 billion yuan during the 12th Five-Year in speeding up the grid development in Xinjiang. The company will focus on constructing Southern Hami-Zhengzhou, Northern Hami-Chongqing, Zhundong-Sichuan three-loop UHVDC project, the second channel of 750kV Xinjiang-Northwest Main Grid, and a strong Xinjiang output grid.
