Can this charger be scheduled reliably?
Make sure either the charger or the vehicle can start after 11 p.m. and stop before 7 a.m.
Short answer: if you can schedule most home EV charging between 11 p.m. and 7 a.m., Georgia Power's Overnight Advantage plan can make home charging much cheaper than daytime home charging or public fast charging.
Rate windows
What are the Overnight Advantage hours?
Georgia Power's page describes three windows: super off-peak from 11 p.m. to 7 a.m., off-peak for the rest of the non-summer-peak hours, and summer on-peak from 2 p.m. to 7 p.m. on weekdays from June through September.
The page text lists the super off-peak rate as 2.1859 cents per kWh and also summarizes it as about $0.023 per kWh. Rate pages can change through regulatory filings, so confirm the current tariff before switching plans.
Charging math
What does that mean for an EV?
A typical Atlanta driver who adds 30 kWh overnight would pay far less at super off-peak pricing than at daytime rates. The exact bill depends on taxes, fees, monthly account terms, and how much other household usage shifts into or out of peak windows.
The key operational habit is simple: install a Level 2 charger, set the car or charger schedule to start after 11 p.m., and avoid charging during the summer weekday on-peak window unless necessary.
The tradeoff
Overnight Advantage is not automatically best for every home. It rewards overnight usage and penalizes summer weekday afternoon/evening usage. If your air conditioning, cooking, laundry, and other loads spike during on-peak hours, the EV savings may be partly offset.
Installation choices
What charger setup fits overnight charging?
Level 2 charger
A Level 2 charger is the right default for overnight charging because it can recover a normal day of driving during the super off-peak window.
Scheduling controls
Most EVs and many wall chargers support charging schedules. Ask your installer whether the charger app or your vehicle app should control the schedule.
Panel capacity
If your panel is tight, a load management device may let you install Level 2 charging without a full panel upgrade. See the Atlanta cost guide for panel-upgrade ranges.
Quote questions
Ask installers these questions
What amperage makes sense for my driving?
The goal is not maximum amperage. The goal is enough charging speed to refill during the low-cost overnight window.
Will my panel support the load?
A load calculation should be part of the quote, especially if you have an older panel, heat pump, pool equipment, or other large loads.
