Time of Use Pricing

 Time of Use Pricing 


What is Time of Use Pricing?

Time of Use Pricing (TOU) is a program that BGE provides in which the supply portion of your electric bill will vary based on the time of day that the energy is consumed. The supply portion of a bill makes up about 70% of the average residential electric customer’s bill.  By utilizing TOU pricing, you can shift your electricity usage to hours where electricity costs the least, thereby lowering your total bill.

TOU pricing is an option to all Residential customers.  In addition, it is an option for all Commercial customers who have monthly demand less than 60 kW. Larger commercial customers with monthly demand greater than 60 kW are automatically enrolled in TOU pricing.


How Does it Work?

TOU rates are based on the amount of energy you use and when you use it. Your rate will vary according to the time of day or night, and day of the week, and season of the year. Think about the time of day you use the most energy, or season of the year. Summer? Winter?  Most of the low-rate periods are nights and weekends. Under TOU pricing, there are three different prices for three different periods:

  • On-Peak
  • Intermediate-Peak
  • Off-Peak

On-Peak is when electricity costs the most money.  In the Summer, the On-Peak period is weekdays from 10 a.m. to 8 p.m. In the Winter, the On-Peak period is weekdays from 7 a.m. to 11 a.m. and 5 p.m. to 9 p.m.

Intermediate-Peak, prices are slightly lower.  In the Summer, the Intermediate-Peak period is weekdays from 7 a.m. to 10 a.m. and 8 p.m. to 11 p.m. In the Winter, the Intermediate-Peak period is weekdays from 11 a.m. to 5 p.m.

Off-Peak, prices are the lowest.  In the Summer, the Off-Peak period is weekdays from 11 p.m. to 7 a.m. In the Winter, the Off-Peak period is weekdays from 9 p.m. to 7 a.m. Saturday, Sunday, and designated major holidays (New Year’s Day, President’s Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas and Mondays following any of those holidays that fall on a Sunday) are always considered Off-Peak periods.

Your ability to reduce your bill depends on a number of factors, such as the type of business you operate and the amount of energy you use that can be shifted to a lower-cost period or spread over a 24-hour timeframe.  A 24-hour convenience store or gas station is usually a good candidate for TOU because their energy use can be spread across Intermediate and Off-Peak hours. Additionally, if your residential home is empty during the day or if you can shift the energy you use to a lower-cost period (i.e. doing laundry at night, etc.), then you may be a good candidate for TOU.

If you purchase your electricity from a supplier other than BGE, BGE’s generation and transmission Time-of-Use rates do not apply. Please check with your supplier for their rates. You may be able to obtain TOU rates from another supplier.
