Power generator NTPC Limited said it has commissioned country’s first ultra-super critical generation unit of 660 Mw at Khargone in Madhya Pradesh. This plant operates at an efficiency of 41.5 per cent which is 3.3 per cent higher than the conventional super critical units with steam parameters of 6,000 degree Celcius temperatures and 270 kg/cm2 pressure.
An ultra super-critical power plant use less coal per megawatt as compared to a conventional thermal power unit. This leads to lower emissions (such as of carbon dioxide and mercury), higher efficiency and also reduces cost of fuel per Mw of power produced. "The
