State Grid Corp of China (SGCC), a major power grid operator, plans to construct next year an ultra-high voltage carrier that will transmit electricity generated by wind and thermal power plants in Inner Mongolia to Jiangsu province, a company executive said yesterday.

Work on the 1,300-km transmission line is awaiting the government's nod, Shu Yinbiao, deputy general manager of SGCC, said yesterday.

"With the use of ultra-high voltage (UHV) technology - the most advanced technology in power transmission - the rich coal mining resources and wind energy in Inner Mongolia can be better utilized," said Shu.

Electricity generated by many wind farms in Inner Mongolia cannot be connected to the power grid at present due to a lack of power transmission capability, causing large wastage of energy. Advanced technology, in the form of a smart grid, is sorely needed, analysts said.

Power transmission lines using the UHV technology can carry up to 1,000 kV.

Compared with conventional lines they can transmit electricity over longer distances, and more efficiently, analysts said.

"More UHV projects are needed for the continued development of China's energy industry," said Shu.
