Energy 63
We’re opening up a new dimension in HVDC technology with the construction of the world’s largest high-
voltage direct-current transmission system. When completed, this 800-kV low-loss link will stretch some
1,400 kilometers across China – from hydropower plants in Yunnan to the industrial region of Guangdong
Province. With a capacity of 5,000 MWs, the system will eliminate the need for new fossil fuel plants that
would spew more than 30 megatons of CO2 into the atmosphere every year.
The rising demand for energy worldwide, mounting load densities in the world’s fast-growing cities and
dwindling resources are creating major challenges for power transmission and distribution. As a result,
utilities and industrial consumers are turning more and more to innovative, environmentally compatible
solutions. And that’s exactly where our expertise, effi ciency and global presence make us a strong, reliable
partner. For example, our recently launched HVDC Plus solution offers a low-loss, ecofriendly transmission
link that intelligently connects offshore wind farms with mainland power grids. And it’s not only in the
HVDC sector that we’re a trendsetter. As an active participant in the European Smart Grid Initiative, we’ve
already developed the technologies needed to make intelligent power networks a reality.
Our portfolio is carefully tailored to the requirements of our market – in terms of technologies and solu-
tions as well as market coverage and global positioning. Focused on Europe, North America, China, India
and, increasingly, Russia, we’re No. 1 or No. 2 in every major power transmission and distribution market
in the world. In an extraordinarily positive environment, we’re growing substantially faster than our
market.
Power Transmission
and Distribution (PTD)
As a provider of innovative, effi cient solutions for power transmission
and distribution, PTD develops and manufactures high- and medium-
voltage switchgear, transformers and substations, automates power
grids and provides services worldwide. Our solutions enable electricity
to be transported reliably and economically from the power plant to
the consumer.
