It is usage of plants that matters, not number of plants. Most of the new Chinese coal plants mostly have have low capacity factors. They are being built as backups and peakers rather than baseload, designed (or retrofitted in the case of existing plants being upgraded) to be able to cycle up and down to balance wind and solar. Many are idle so much that their owners have financial difficulty keeping them open, and the government has had to start paying them for their idle time so they won't go under. Many are also built to replace existing plants that cannot not yet be replaced with renewables, so are at worst neutral on coal usage and are usually actually more efficient than the old plants so there is a reduction.
