role of coal mill in thermal power plant
Managing power system flexibility in India via coal plants
ResultCoal plants in India are incentivized to run at an average PLF of 85%, which is also known as the normative PLF. However, the average PLF of coal-based power plants has decreased from 78.9% 8 in 2007–08 to 62% in 2015–16 9 ( Fig. 4 ). In 2018, coal plants were operating at an average PLF of ~61%.
