That's because India has to. Domestic demands are huge and India's coal isn't very high in quality. Not to mention coal power is largely state-controlled and doesn't allow for much private frolicking.
It's quite the opposite situation than the US, where coal is extremely high-quality and private player participation is unrestricted.
Almost all new energy construction is non-coal. Coal has collapsed even here in the US, and the current administration is unlikely to seriously change the trajectory. Gas is increasing, but mostly here in the US, but production is dropping again.
