With the aim of reducing emissions, power behemoth NTPC will for the first time commission a 660 MW unit based on ultra-supercritical technology by June.
The ultra-supercritical technology burns coal at a much higher efficiency. Across the country, most of the power plants are based on sub-critical technology, which has a 38 per cent thermal efficiency. It means that 38 per cent of thermal energy gets converted into electrical energy. In the ultra-supercritical plant, this efficiency is 44 per cent.
The power unit is a part of the Khargone Power Plant in Madhya Pradesh, which is still under-construction. The second unit of the plant is also with the same technology.
