India to have its first coal-fired AUSC plant by 2017

India's first 800 MW coal-fired Advanced Ultra Supercritical (AUSC) power plant will be operational by 2017 which will help reduce operational costs and emit less carbon dioxide than existing similar units.

India's first 800 MW coal-fired Advanced Ultra Supercritical (AUSC) power plant will be operational by 2017 which will help reduce operational costs and emit less carbon dioxide than existing similar units.

The AUSC will have five % more efficiency than the existing thermal plants and help in 12 % savings in coal thus reducing the overall amount of carbon dioxide emission, Dr S C Chetal, Director, Reactor Engineering Group of IGCAR and a distinguished scientist told PTI.

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 and 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 and 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.

This kind of very high temperature and pressure will improve the steam cycle efficiency, which in turn means that for a given electrical output there will be less consumption of fuel (coal) and less release of carbon dioxide, he said.

After developing this technology, India will be one of the leaders in the world in terms of thermal power plant technologies, the scientist said.

"Once we are able to built and operate the AUSC, it is possible to decrease the cost of the coal fired supercritical thermal plants in the country," he said.
