I think these numbers are approximately correct for China 2025:
Generation additions
Source TWh
Solar 436
Wind 254
Nuclear 21
Total 711
Demand growth
Growth 684
FF saving 27
So that's about 3-6 coal plants that can be closed (they average 50% capacity)
Clean power deployment is growing faster than electricity demand (even as China electrifies more things) so this should be the start of the FF replacement.
