Question 1

Does a time of use plan actually save money?

Accepted Answer

Yes, you can save substantial money with a TOU plan, provided you shift a meaningful portion of your electricity usage to off-peak hours. Simple habits like running major kitchen appliances late at night, charging electric vehicles overnight, and pre-cooling your home before 4:00 p.m. lead to much lower bills. If your heavy usage stays concentrated during peak weekday afternoons, however, a TOU plan will likely cause your bill to increase.

Question 2

What are standard peak and off-peak hours?

Accepted Answer

For most utility companies across the country, the most expensive peak hours occur on weekdays between 4:00 p.m. and 9:00 p.m. when families return home and run air conditioners and appliances simultaneously. Conversely, electricity is cheapest during off-peak and super off-peak hours — typically stretching from 10:00 p.m. to 6:00 a.m. when most households are asleep and grid demand plummets — with the remaining daytime hours acting as moderate shoulder periods.

Question 3

Do I have to switch to a time of use plan if I install solar panels?

Accepted Answer

In many solar markets, yes. For example, California's Net Billing Tariff (NEM 3.0) requires all new residential solar customers with PG&E, SCE, or SDG&E to enroll in specific time of use plans. Even in states where TOU enrollment isn't required for solar homeowners, utilities strongly incentivize it, and pairing solar panels with a home battery backup system on a TOU rate is often the best way to maximize your energy bill savings.

Question 4

How do time of use rates change between summer and winter?

Accepted Answer

Utilities typically adjust TOU schedules twice a year to match seasonal weather demands. Summer schedules (usually June through September) feature steep peak rates from 4:00 p.m. to 9:00 p.m. to combat heavy air conditioning loads. Winter schedules (October through May) usually have smaller price differences between tiers and often split peak hours into an early morning heating window and an evening window, while offering cheap super off-peak rates midday when solar generation is high.

Question 5

What is the difference between time of use rates and critical peak pricing?

Accepted Answer

Time of use (TOU) rates follow a predictable, everyday schedule where prices change at set hours all season long. Critical Peak Pricing (CPP) is an event-based surcharge triggered only during extreme weather emergencies or severe grid strain, usually 10 to 15 times a year. When a CPP event is called, your utility notifies you a day in advance that peak prices will temporarily spike much higher than normal, often offering lower off-peak rates the rest of the year in exchange for your participation.

Question 6

Are free nights and weekends plans considered time of use?

Accepted Answer

Yes, free nights and weekends plans are popular variations of Time of Use contracts in deregulated energy states. Instead of just discounting the rate during off-peak hours, the retail provider drops the energy charge to zero cents during specific nightly or weekend windows, while charging a significantly higher rate during weekday daytime hours to make up the difference.

Question 7

How do I know if I have a TOU rate plan or if I can opt out?

Accepted Answer

The easiest way to check is to review your recent electric bill or your plan's Electricity Facts Label (EFL) for line-item charges that vary by time of day. If you find that a time-varying structure doesn't fit your lifestyle, you can typically opt out by calling your utility company to switch back to a flat-rate plan (unless you are subject to mandatory solar TOU rules). In deregulated markets, you also have the freedom to shop for independent providers like Gexa Energy to compare fixed and dynamic plan options.
