(Reuters) - China's power engineers have become world leaders in ultra-high-voltage transmission systems connecting far-off power sources with cities hungry for electricity.
China already has seven ultra-high-voltage (UHV) lines in operation, more than any other country, carrying power over thousands of kilometres at around 800,000 or even 1 million volts.

The National Energy Administration, which is part of the powerful National Development and Reform Commission, the country's top economic regulator, has ambitious plans for as many as 12 inter-regional ultra-high-voltage transmission corridors spanning the country.

... according to SGCC, top officials, including Chinese Premier Li Keqiang, endorsed the UHV super-grid strategy at a meeting in April.
"The Premier's stance ended the argument of whether to construct UHV. The answer is YES and MORE. This year will be a golden era of approving and constructing lots of UHV projects."

China is also building UHV grids in other countries:
In February, a consortium led by SGCC won a 30-year concession to build and operate a 2,000-km (1,240-mile), 800kV UHV line in Brazil. The transmission system will carry power from the Belo Monte dam in northern Brazil to the major consumption centres in the southeast.
