China is currently building coal power plants to replace old, less efficient and dirtier plants. Then they use them for base load / network stabilization while they build up ridiculous amounts of energy storage. They’re not running all the time, only to compensate variability in renewables power generation while they build up storage. They’ll probably be taken out of use in a few decades without having much runtime.

For installed capacity the new power plants don’t change much as they take old ones offline - percentage wise coal is falling due to the ridiculous speed of building renewables.
