Georgia Power is proposing retiring about 1GW of coal in its latest Integrated Resource Plan(IRP). The proposed coal closures, and the additional solar/storage in this IRP are pretty conservative. However, assuming that the Vogtle nuclear units under construction remain on schedule - big assumption - I would expect the 2022 IRP to propose shutdowns of Wansley coal (1,744 MW) and at least a couple of units at Bowen(1,448 MW) coal plant. This will leave a couple of coal units(1,754MW) at Bowen as well as the four units(3,400) at Scherer coal plants.

After 2022 the increased generation from Vogtle units as well as new solar generation will mean that most of the remaining 32 TWh of coal generation in Georgia will have been replaced. By the 2025 IRP Georgia Power will be able to close the remaining two units at Bowen. By 2031, the four units at Scherer will close and Georgia will be coal-free.
