Time-Of-Use Residential Rate Plans

Time-Of-Use (TOU) Rate Plans

If you are able to manage your energy habits, one of our Time-Of-Use plans may be the best fit for your home. Rates on a TOU plan are based on the time of day and the season.

TOU plans can help you manage your energy costs. By taking advantage of lower rates on nights and weekends, you can avoid higher weekday rates when energy resources are in demand.

NOTICE: The California Public Utilities Commission requires us to begin switching customers to Time-Of-Use (TOU) Plans in 2018. This change will be a multi-year effort. You will receive multiple communications in advance of being switched.

  • Electricity rates are lower on nights and weekends
  • Rates are higher during weekday daytime hours
  • Yearly energy expenses can be lower, but bills may be higher in the summer

Rates Glossary

Baseline Allocation

An amount of electricity (measured in kilowatt hours) that is provided to households at a lower rate than electricity used above this threshold.

Baseline allocations are determined by the California Public Utilities Commission (CPUC) based on the number of days in the billing period, the season, the climate, and whether your primary source of heat is electric.

Baseline Allocation (Daily/Monthly)

Since billing periods can have different numbers of days, the baseline allocation is defined initially as a daily allocation. This is then calculated into an allocation for the entire billing period, which is sometimes called a “Monthly Baseline Allocation” for convenience.

Baseline Credit

A discount that reduces total electricity charges. A baseline credit is calculated per kilowatt hour (kWh) used and is capped by the monthly baseline allocation.

Daily Basic Charge

A flat, daily charge that is billed on a monthly basis, regardless of customer use or activity.

Kilowatt Hour (kWh)

A unit of measurement for electrical energy consumption over time that we use to compute billing. One kilowatt hour is equivalent to using 1,000 watts for 1 hour.

Minimum Daily Charge

A flat, daily charge that is applied if a customer’s total delivery charges fall below a minimum in a billing period (about $10 for a typical residential user). This charge supports the maintenance and operation of providing electricity.


An amount of energy allocated to a customer in a billing period at a specific price. If a customer uses more energy than what is allocated, they are charged at a higher rate on the next tier.

Residential Time-Of-Use FAQ

What if I enroll on a time-of-use rate plan, and then change my mind and want to switch back?

There is no minimum commitment period, and you can choose to sign up or un-enroll from the TOU-D or TOU-D-T rate plans at any time. The Electric Vehicle Plan (TOU-EV-1) does require a separate meter and there is a 12 month commitment time period. Keep in mind that if you switch from a time-of-use rate plan to an alternate plan, you will not be able to make another switch for a full 12 months.

How do I find my baseline allocation?

Each customer has two baseline allocations, one for summer and one for winter usage. Baseline allocation is the same as the baseline allowance found on the standard residential rate plan. Your allowance can be found by reviewing the “details of your new charges” section of the bill statement. Under “additional information” you will see your summer baseline allowance, your winter baseline allowance, or both, depending on which month’s bill you review. For more information about baseline, view the “about baseline” section of the standard domestic rate plan page here.

Does the High Usage Charge apply to Time-of-Use rate plans?

TOU Rates are not subject to the High Usage Charge.

If I am on a Time-of-Use Rate plan, do I still have the minimum bill charge?

TOU Rates Plans A and T are also subject to a minimum bill charge averaging out to about $10 a month. This means that if the delivery portion of your bill does not meet the minimum bill amount of $0.32 per day, a charge will be added to your bill for the difference to reach approximately $10. The delivery charges and the daily basic charge of $0.03 per day apply towards your minimum bill charge.

How does Medical Baseline impact my baseline allocation?

Medical Baseline customers have an additional 16.5 kWh allocated to their baseline usage on a daily basis, in addition to their applicable seasonal baseline for the operation of life-support devices and other qualifying equipment.
