Calculator
Estimate the effect of Time of Use pricing on your electric bill.

This calculator illustrates how you can save money by shifting your energy use from on-peak to mid- and off-peak hours. It does not represent what your bill will be.

These estimated energy charges do not reflect your total bill, which includes other charges that apply to all PGE customers, such as basic charge, distribution and supplemental adjustments. These other charges are standard for all PGE customers and will appear on your bill.

Energy costs shown are based on an average customer’s usage pattern. Your individual time-of-day energy usage may vary.

Enter the number of kilowatt hours from your most recent PGE bill, select the type of customer shown on your Power Options enrollment form, and click “Calculate.”


Monthly kWh
 kWh/month used by average customer; or enter the kWh from your bill.

*These charges do not reflect your total bill. They do not include other charges that apply to all PGE customers, such as basic charge, distribution or supplemental adjustments. These other charges apply to all PGE customers and will appear on your bill. Under the Time of Use option, you also receive 0.722 cent per kWh credit for the first 1,000 kWh, which is included in the above calculations.


The more kilowatt-hours you shift to off-peak hours, the more you could save.

The calculator assumes that the average PGE customer uses approximately 20.58 percent of his or her total kWhs during on-peak times, 40.83 percent at mid-peak and 38.59 percent during off-peak hours. The average Time of Use customer uses 18.4 percent on-peak, 38.3 percent mid-peak and 43.2 percent off-peak. Your individual usage may vary, affecting the likelihood of your savings under Time of Use pricing.

To manually calculate the estimated effect of shifting your energy use to mid- or off-peak time periods, use our advanced calculator.

Calculating Time of Use savings for an electric vehicle
If adding an electric vehicle significantly changes your home electricity use, you may be able to save money by choosing our Time of Use rate plan rather than the Basic Service plan. As a guide, if you drive your electric vehicle 1,000 miles a month, you would use approximately 250 kWh of electricity per month just for your vehicle.
