| NOTES: Planned Capacity Additions reflect plans to begin operating new units and plans to uprate existing units. Planned Capacity Reductions reflect plans to retire or derate existing units. Actual Capacity Additions reflect new units, uprates to existing units, corrections to previously reported capacities, and additions not previously reported. Actual Capacity Reductions reflect retirements of and derates to existing units, corrections to previously reported capacities, and reductions not previously reported. Capacity from facilities with a total generator nameplate capacity less than 1 MW are excluded from this table.
