Those are supercritical plants being built to replace the older and much less efficient ones.

You can tell by their relatively flat CO2 emissions from coal, even though the power they generate is still slowly increasing.

Those plants are a stop gap measure to limit emissions while renewable and nuclear plants are being built. Electricity generated from coal as a percentage has been steadily decreasing for more than a decade now. Transition takes time, but they are certainly moving in the right direction.
