Construction of an ultra-high voltage power transmission linedesigned with the world's largest capacity started Sunday inChina's far western Xinjiang region. The 800 kv ultra-high voltage direct current (UHVDC) transmissionline connects the energy base of Hami prefecture in easternXinjiang with the central city of Zhengzhou, according to the StateGrid Corporation of China (SGCC), the project contractor. The 2,210-km-long line goes through the vast region of Xinjiang,Gansu, Ningxia, Shaanxi, Shanxi, and Henan. It costs 23.39 billionyuan (3.7 billion U.S.dollars), and is designed to have atransmission capacity of 8 million kw upon completion in 2014,setting up a new world record. The line will transmit 37 billion kwh on average annually,according to Liu Zhenya, general manager of the State GridCorporation of China. "We can reduce 317,000 tonnes of sulfurdioxide and 267,000 tonnes of nitrogen oxide which would otherwisebe produced during the transportation," Liu said. Zhou Yongkang, a member of the Standing Committee of the PoliticalBureau of the Communist Party of China (CPC) Central Committee,attended the construction launch ceremony in Xinjiang. In the meantime, a second 750-kv HVDC transmission line which linksXinjiang with the main network of the Northwest China Grid Co. Ltd.kicked off on Sunday. With an investment of 9.56 billion yuan, the 2,180-km-long linewill become the major route to transmit wind and solar powergenerated in Hami prefecture, Jiuquan city of Gansu province, andQaidam basin in Qinghai province to the rest parts of the country. The construction boom of the ultra-high voltage power transmissionlines came as the country strives to transmit the electricity fromthe energy-rich west to the booming central and eastern regions. Xinjiang has 2 trillion tonnes of coal reserve, one third of whichis in Hami. Meanwhile, Hami is one of the country's major windpower bases. China's large energy bases are mostly distributed in the west andnorth, more than 2,000 km from the power network load centers inthe eastern and central regions, said Zhang Guobao, director ofExpert Advisory Committee under the National Energy Administration. "The ultra-high power transmission lines are a way out for thecountry's imbalanced distribution of energy reserve," Zhang said. Ultra-high voltage power transmission (UHVPT) projects, however,have met many obstacles, as some doubt whether the technology ismature enough and can bring about economic benefit. China has been suffering prolonged and ever worsening powershortage in recent years, a driving force for the country todevelop long-distance, high-voltage power transmission lines. Starting from March 2011, an unprecedented power shortage sweptmost southern and eastern provinces and municipalities, with asupply gap of 30 million kilowatts, according to China ElectricityCouncil. "In spite of the controversy, the projects will continuously becarried forward," said Zhou Fengqi, deputy president of ChinaEnergy Society. Industry insiders have said the State Grid Corporation of Chinawill push for the construction of four alternating current andthree direct current ultra-high voltage power transmission linesacross the country, with an investment exceeding 300 billion yuanin 2012 alone.
