Alstom Grid has entered into a cooperation agreement with China Electric Power Equipment and Technology (CET) to develop ultra-high-voltage direct current (UHVDC) power transmission systems in China.

Under the terms of the agreement, CET and Alstom will assist in the development and manufacture of 1,100kV and 800kV converter transformer technology.

The development of UHVDC transmission systems will allow efficient transmission of bulk electricity over longer distances in China.

CET is a wholly owned subsidiary of the State Grid Corporation of China, holding a 100% stake.
