Kalpakkam, Jan 24 (Agencies): India will be soon listed among the world leaders in terms of power plant technology with its first 800 MW coal-fired Advanced Ultra Supercritical (AUSC) plant that will be operational by 2017.

The AUSC will have five per cent more efficiency than the existing plants and help in 12 per cent savings in coal thus reducing the overall amount of carbon dioxide emission, said Dr SC Chetal, the Director of Reactor Engineering Group of IGCAR and a distinguished scientist.

A joint effort of Indira Gandhi Centre for Atomic Research (IGCAR), Bharat Heavy Electricals Limited (BHEL) and National Thermal Power Corporation (NTPC), the Advanced Ultra Supercritical power plant will be the first such indigenous plant, he said.

"At present there is no AUSC plant operating in the world and we will back the first indigenous AUSC with strong R&D with IGCAR's expertise in design, materials and manufacturing technologies of the fast breeder reactor," Chetal said.

Presentation of the project has already been made to Prime Minister Manmohan Singh and "we are waiting for the approval for R&D funds which is expected to come soon," he said.

Of the total cost of Rs 7000 crore of the project, Rs 2,500 crore will be spent on research and development and public sector units, sources said.

IGCAR, BHEL and NTPC signed an MoU for AUSC system in August last year.

The advanced ultra super-critical boilers, to be designed and developed by IGCAR, will be able to operate at a pressure of 300 kg per sq cm and 700 degree centigrade temperature, Chetal said.

The existing supercritical plants use imported technology. A large number of operating plants in the country (BHEL-NTPC) are of subcritical type running at 170 kg per sq cm pressure and 540 degree celsius.

Recently, India introduced supercritical thermal plants—of 660 MW and 800 MW running at 565 degree Celsius in the mainstream line and with a supercritical pressure of 250 kg per sq cm.

India is planning to have 58 units based on supercritical plants from the 12th five year plan onwards. But these plants are being built under foreign collaboration with large import content.
