ABB To Provide Link Worth $900M For Indian Power Superhighway
Feb 23, 2011 - Wall Street Journal
ZURICH (Dow Jones)--ABB Ltd (ABB) Wednesday said it has been selected by Power
Grid Corporation of India Ltd. (PGCIL) to deliver an ultrahigh-voltage transmission
system, worth about $900 million. The link will supply hydropower from northeastern
India to the city of Agra over a distance of 1,728 kilometers.
-ABB said it has been chosen to execute the North-East Agra transmission project
together with BHEL (Bharat Heavy Electricals Limited), a leading Indian government-owned
power company that will deliver the remainder of the project worth more than
$1.1 billion in total. The order will be booked on completion of financing
--The ultrahigh-voltage direct current (UHVDC) link operating at 800 kilovolts
(kV) will have a converter capacity of 8,000 megawatts (MW), the highest ever
built. When operating at full capacity, the link will be able to supply enough
electricity to serve 90 million people based on average national consumption.
Using ultrahigh-voltage minimizes transmission losses and improves efficiency.
--"The North-East Agra transmission link sets a new standard in ultrahigh-voltage
power transmission and underlines ABB's global leadership in HVDC technology," said
Peter Leupp, head of ABB's Power Systems division. "We are pleased to
continue supporting India in the development of its power infrastructure."
--The system will be the world's first UHVDC link with three converter stations:
Two "sending" stations will convert power from AC to DC for transmission
over a single power line that will pass through the narrow Siliguri Corridor
and deliver electricity to the third, "receiving" station in Agra
where it will be converted back into AC for distribution to end users.
--The multi-terminal solution considerably reduces costs compared to the alternative
of running separate power links from multiple hydropower plants to Agra. The
project will be executed on a turnkey basis including design, system engineering,
supply, installation and commissioning. This is ABB's second multi-terminal
HVDC link: The first was constructed in North America in 1990-92.
--UHVDC transmission is a development of HVDC, a technology pioneered by ABB
more than 50 years ago, and represents the biggest capacity and efficiency
leap in over two decades. ABB is a world leader in HVDC transmission technology,
with many pioneering achievements and over 70 HVDC projects around the world
with a combined transmission capacity around 60,000 MW.
