Thermal plants equipped with carbon capture, utilisation and storage techologies are also expected to play an important role in providing flexibility. Plant operators can run them in a flexible manner to accommodate shortterm variations, very much like unabated thermal power plants today. These technologies have various effects on plant operation.

Most of the coalfired power plants have efficiencies less than 35% by using indigenous high ash coal. Now a day, efforts are taking place to bring in highly efficient super critical technology in the country for thermal power plants. Energy analysis of coalfired power plant is done using mass and energy balance equation [2].
