The Fine-Print Catches: 4 Rules Utility Brochures Bury
The 2.23¢ overnight figure is only the base energy charge
TOU-OA-15 lists Super Off-Peak energy at 2.2272¢/kWh. Official three-part fuel (TOU-FCR-TP-5) adds 3.4747¢/kWh in those hours for secondary customers, before estimated ECCR, DSM, franchise, and tax.
The $12.44/kW Smart Usage Demand Trap Runs All 12 Months
Even in January at 2:00 a.m., Smart Usage bills $12.44/kW (+ riders) on your highest single clock hour. Running an 11.5 kW (48A) EV charger simultaneously with electric heat strips or a dryer (16 kW) adds ~$200+ to that month's bill.
When Smart Usage Wins: Battery Demand Shaving (<3.5 kW)
If you own a home battery + load controller programmed to cap grid imports below 3.5 kW every hour of the month, Smart Usage's cheap daytime winter/weekend kWh rate beats Overnight Advantage by $500+/year.
12-Month Tariff Term Commitment
Georgia Power enforces a 12-month term on TOU-OA and TOU-RD, preventing seasonal flipping between October and June.

Worked Household Bill Math: Real-World Scenario
Alpharetta, GA EV household — 1,650 kWh/month (official energy + fuel; other riders estimated)
No home battery; 48A Level 2 EV charger scheduled 11:30 p.m.–5:30 a.m. (11.5 kW peak hourly draw).
- Load-shape assumption (not a tariff): 42% of kWh in the 11 p.m.–7 a.m. window; summer on-peak kWh averaged over the year.
- Overnight Advantage is billed on official TOU-OA-15 energy charges plus official TOU-FCR-TP-5 fuel by period.
- Smart Usage is billed on official TOU-RD-12 energy and $12.44/kW demand plus official TOU-FCR-7 fuel.
- ECCR, DSM, and franchise are added only as a labeled estimate. Uncheck the riders box to see official energy + fuel alone.
Frequently Asked Questions (Georgia Power)
Why is my Overnight Advantage bill higher than 2.23 cents per kWh?
2.2272¢ is only the official Super Off-Peak base energy charge on TOU-OA-15 (June 2026). Fuel Cost Recovery on those hours is 3.4747¢/kWh for secondary customers under TOU-FCR-TP-5, and other riders still apply.
Does the $12.44/kW demand charge on Georgia Power Smart Usage apply overnight?
Yes. Smart Usage measures your highest 60-minute kW demand across ALL hours of the month—even at 2:00 a.m. Plugging in an 11.5 kW (48-amp) EV charger overnight sets at least an 11.5 kW demand floor ($143.06/month before riders).
Should I throttle my EV charger amps if I am already stuck on Smart Usage?
Yes! Lowering your Level 2 EV charger from 48A (11.5 kW) down to 20A–24A (4.8–5.7 kW) and charging strictly after your AC and electric water heater cycle down can cut your monthly Smart Usage demand charge by $70 to $90/month immediately.
