Advanced Ultra Super Critical (AUSC) Technology

AUSC refers to an advanced power generation system that works on higher temperatures (around 700°C) and pressure, thus achieving a great improvement in efficiency, reducing coal consumption and CO2 emissions. In August 2016, the Cabinet Committee on Economic Affairs (CEEA) had given its approval for the development of AUSC technology for thermal power plants for three government entities. Power generation from coal-fired power plants contributes to about 38% of CO2 pollution in the atmosphere. AUSC technology which is still in research stage will help in 20% reduction in CO2 emission at source combined with 20% saving in coal consumption compared to sub-critical plants.

AUSC technology will enable Indian industries to design, manufacture and commission higher efficiency coal-fired power plants with indigenously developed technology. This will be the first time large power plant equipment will be manufactured without any technological collaboration or licensing agreement with foreign companies. Use of this technology in all future large coal-fired power plants will ensure energy security for the country for a longer period as well as greener environment.
