ABB secures $900m power superhighway for India
India to receive ultra high voltage DC link for hydro power
A 1,728km power superhighway worth almost US$1 billion is to be built by ABB in India, delivering a high-voltage transmission system to link the city of Agra to northeastern India.
Selected by the Power Grid Corporation of India (PGCIL), ABB has been chosen, along with Indian government-owned Bharat Heavy Electricals Limited, to construct the link, which is planned to supply hydropower to the city.
The ultra high-voltage direct current link operating at 800Kv will have a converter capacity of 8,000 megawatts; the highest ever built. Using ultra high voltage minimises transmission losses and also boosts efficiency.
Commenting on the project, Peter Leupp, head of ABB’s Power Systems division, said: “The North-East Agra transmission link sets a new standard in ultrahigh-voltage power transmission and underlines ABB’s global leadership in HVDC technology. 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, which will pass through the narrow Siliguri Corridor and deliver power to the third receiving station in Agra, where it will be converted back to AC for distribution.
The multi-terminal solution considerably reduces costs compared to the alternative of running separate power links from multiple hydropower plants to Agra, and the project will be executed by ABB on a turnkey basis including design, system engineering, supply, installation and commissioning.
