China starts up world’s longest UHV line
    2019-01-04  08:53    Shenzhen Daily

STATE Grid Corp. of China has started up the world’s longest and most-powerful ultra-high voltage (UHV) power line from its far northwest to the heavily populated east.

The 1,100-kilovolt direct-current Changji-to-Guquan project stretches 3,293 kilometers, the nation’s biggest electricity distributor said in a statement Wednesday. That’s roughly the distance between Los Angeles and Cleveland. The 40.7 billion yuan (US$5.9 billion) project, which the company referred to as the “Power Silk Road,” was approved in December 2015 and construction started the next month.

China has increasingly relied on ultra-high voltage technology to send electricity from remote regions with excess supply to areas of higher demand. Xinjiang, where the new line starts, is home to large-scale wind and solar projects, but also the nation’s worst curtailment rates, or capacity that’s idle because of grid congestion, according to the National Energy Administration.

The National Energy Administration has also banned the construction of new coal-fired plants in Xinjiang, as well as 20 other provinces and regions, because of an expected overcapacity.

The project is “part of the nation’s strategy to shift electricity from the west to the east to ease electricity surplus in the west, given a backdrop that such infrastructure investments can drive economy,” said Kou Nannan, head of China Research at Bloomberg NEF in Beijing.

The new line, which can transmit 12 gigawatts of power, runs through Gansu, Ningxia, Shaanxi and Henan before ending in Xuancheng of Anhui Province. It can supply 66 billion kilowatt hours of electricity to eastern China annually, meeting power demand of 50 million households and reducing coal use by 30.24 million tons, State Grid said.

Yang Xinfa, director of State Grid’s reform office, said last week that the firm would actively solicit social capital in ultra-high voltage projects.

“State Grid will proactively engage insurance companies, large-scale industrial funds and State-owned investment platforms in regions covered by ultra-high voltage programs to take part in the programs,” said Yang.

Yang said State Grid and its business partners will invest in and operate new ultra-high voltage direct current projects by establishing joint ventures to promote the development of power grids and share the fruits of reform. (SD-Agencies)
