Learn what time-of-use rate plans mean for your business
Maximize your savings with time-of-use rates
Time-of-use rate plans can help you save money because they offer lower energy rates when energy demand is low. Conversely, costs increase when demand is high. You can reduce your expenses by shifting your energy use to partial-peak or off-peak hours of the day. Rates during partial-peak and off-peak hours are lower than rates during peak hours, which are between noon and 6 p.m. on weekdays, May through October.

Why are businesses switching to time-of-use rate plans?
As part of a plan by the California Public Utilities Commission to ensure greater power reliability and a better energy future, time-of-use rate plans are now the commercial standard for all of the state's major electric utilities.
What is changing in my bill?
Previously, businesses were billed according to flat electric rates, which means they were charged the same amount for electricity no matter when it was used. When you are on a time-of-use rate plan, the cost of electricity will vary based on the time of day and season in which it is used.
What is a peak period?
Peak periods occur from noon to 6 p.m., May through October, when time-of-use rates are higher.
Where can I compare rate plans and can I switch to a different rate plan?
You can change to any other time-of-use or Peak Day Pricing rate plan up to once a year. To compare available rate options and view your daily usage, log in to your PG&E account.
Why does my time-of-use rate vary?
Time-of-use rate plans better align the price of energy with the cost of energy at the time it is produced. Lower rates during partial-peak and off-peak hours offer an incentive for customers to shift energy use away from more expensive peak hours, which can help you save money and reduce strain on the electric grid.
What is the difference between summer and winter time-of-use rate plans?
There are three rate periods during the summer: off-peak, partial-peak and peak, and winter has two rate periods: off-peak and partial-peak. Peak period rates are highest on weekdays, from noon to 6 p.m., May through October. At all other hours, rates will be lower.

How can I save money on a time-of-use rate plan?
Before, on a flat electric rate, the only way to reduce your bills was to simply use less electricity. On a time-of-use rate, you can lower your bill by shifting when you use energy to partial-peak and off-peak hours. Rates during partial-peak and off-peak hours of the day are lower than the rates during the peak hours of 12 - 6 p.m. on weekdays. This puts you in the driver's seat so you can have more control over your bills. PG&E can help you identify ways to shift energy use away from peak hours and conserve energy in your business with rebates for making energy efficiency upgrades.
How do I know if my business is on a time-of-use rate plan?
To find out if your business is on a time-of-use rate plan, log in to your PG&E online account or speak to a PG&E representative at 1-800-468-4743.
Am I getting charged a different rate than a neighboring business?
The rate you are on is based on the amount of energy your business uses every month. A neighboring business may be on a rate that is better suited for their needs, so they may be on a different rate than you.
Frequently asked questions about Demand Charges
What is the Demand Charge on my bill?
To help keep the supply of electricity reliable in California, some time-of-use rate plans, like A10 Time-of-Use, include a Demand Charge to encourage businesses to spread their electricity use throughout the day. This Demand Charge is calculated by using the 15-minute interval during each billing month when your business uses its maximum amount of electricity. As a benefit to this type of rate plan, regular electricity usage charges are approximately 30% lower than for a comparable rate plan without a Demand Charge--giving you the opportunity to save on your bill if you can lower your highest usage 15-minute interval.
Why does my Demand Charge vary from month to month?
The Demand Charge reflects the maximum amount of electricity you used during any 15-minute interval over the course of a billing period, and can vary depending how and when you use your equipment from month to month. One way to lower your monthly Demand Charge is to stagger times at which you use equipment, rather than using all your equipment at the same time, thereby minimizing spikes in your electricity use. Depending on your business type, it may be possible spread your electricity use throughout the day to lower your Demand Charge.
