How the rate works:

Super Off-peak

Every day of the year from 11 p.m. – 7 a.m. It’s cheapest for Georgia Power to produce electricity during these hours so the savings are passed on to you. About 33% of the hours in a year fall in the Super Off-peak time period and it’s the lowest price.


All hours of the year not identified as On-Peak or Super Off-peak From June to September, weekdays from 7 a.m. to 2 p.m. and 7 p.m. to 11 p.m., and during weekends from 7 a.m. to 11 p.m. For October to May, this period is from 7 a.m. to 11 p.m. Prices during this period are higher than the Super Off-peak time period, but much lower than the On-peak time period. The majority of the hours in a year (62%) fall in the Off-peak time period.


Period from June to September, weekdays 2 p.m. to 7 p.m. represents the time when it’s the most expensive for Georgia Power to produce electricity. Although the On-peak period has the highest prices, only about 5% of the hours during a year fall in this period.
