How we compare the plans
- The same usage for each plan. We use one typical hourly usage shape for a home: low use at night, a peak in the evening, more use in summer and a little more on weekends. Each plan gets the same kWh in the same hours, so the time-of-use periods of each plan get the kWh that a real home uses in those hours.
- Twelve months. The months November 2025 to October 2026, each calculated with the rates and riders in effect now (October 15, 2026). The yearly cost does not include future rate changes.
- Options. Each plan uses the default options on its calculator, for example the standard baseline territory, no discount program and the utility's own supply.
- Not included. Taxes, city fees, discounts, solar and the extra kWh of an electric vehicle.
Your own usage is different. To compare the plans with your bill, use Compare plans on the Georgia Power calculator and type the kWh of each period. To compare with every hour of your last year, use your Green Button usage file.

Is a time-of-use plan cheaper on Georgia Power?
It depends on how much of your electricity you use in the peak hours. A home that moves use (laundry, dishwasher, EV charging) out of the peak hours saves more on a time-of-use plan. Type the kWh of each period from your bill, or use your hourly usage file, to compare with your own usage.
