After 2020, a further seven hydroelectric
power projects, with a total rating of
110 GW, are planned in Xizang. The
power from these will be transmitted to
the eastern and southern provinces of
China. To enable the bulk transmission
from these and from other projects, even
further development of UHVDC systems
will be required – either at 1,100 kV DC
or at existing voltage ratings with higher
current-carrying capabilities. Presently,
there is no immediate market interest for
the new UHVDC transmission systems
outside of China. However, this may
change with the emergence of future hydroelectric
and solar generation sources
in Africa, India, the United States and
South America that are far removed from
the centers of consumption and that are
needed to satisfy the world’s apparently
insatiable hunger for power.
