Electricity costs fluctuate every hour of the day. During the work week, especially on hot summer days and dark winter evenings, our costs are higher due to high demand. On nights and weekends, demand for electricity goes down and so does our cost. The Time of Day pricing plan lets you gain an advantage by using energy during the lower-cost time periods.
How does the rate work?
There are three pricing periods with our time of day rates:
| rate type | when it is active |
|---|---|
|
Low rate
|
11 p.m. to 6 a.m. Monday through Friday, plus all hours on weekends and certain holidays |
|
High rate - Summer (June, July, August)
|
11 a.m. to 7 p.m., Monday through Friday |
|
High rate - Winter (December, January, February)

|
Regular rate
|
All other hours |
Specific rates per kilowatt-hour and KW demand (if applicable) depend on the exact rate on which you are billed.
Non-residential customers on the general service rate have an option between three rates:
- GS-1: general service rate that is a flat price per kWh regardless of when a customer consumes energy.
- GS-3: general service rate where the price varies on the time and day of the week and year.
- GD-1: general service rate with a demand (kW) and time of use rate.

For our small business customers, Time of Day Pricing is optional. It is mandatory for customers with demands of 75 kW or higher.
