PG&E Peak Hours Explained: Current Rate Plans and How to Save
PG&E peak hours can impact your electricity cost if you're on a time-of-use (TOU) rate plan. TOU plans vary the cost according to the time of day the power is being used, instead of charging a flat charge. PG&E's residential rates can be expensive compared with the national average, so knowing when electricity costs more can help you make better decisions about when to run major appliances, charge an EV, or use stored energy. This guide explains PG&E peak and off-peak hours by rate plan, why TOU pricing exists, and practical ways to shift electricity use into lower-cost periods.
PG&E's Current Peak Hours by Rate Plan
PG&E has a lot of home rate plans and the specific peak time will depend on the plan you are on. For the rate plans covered here, peak periods generally fall in the late afternoon and evening. These windows matter because many households use more electricity during the same hours. People return home, turn on air conditioning, prepare dinner, run appliances, and charge vehicles.
Rate Plan | Peak Hours | Price Range per kWh |
E-TOU-C | 4 PM - 9 PM, every day | 37¢ - 52¢ |
E-TOU-D | 5 PM - 8 PM, weekdays only | 35¢ - 48¢ |
E-ELEC | 4 PM - 9 PM, every day | 28¢ - 54¢ |
E-TOU-C
E-TOU-C uses a 4 PM to 9 PM peak period every day, so electricity used during these hours can cost more than usage earlier or later in the day. If your household can shift flexible activities outside this window, you may reduce electricity purchased at higher rates. Check your current plan and bill before changing your routine, as rates and plan details can change. Check with PG&E for the latest information before you change your daily electricity use.
E-TOU-D
E-TOU-D's daily peak period is shorter, from 5 PM to 8 PM. There is no similar peak period on weekends. This can make Saturday and Sunday good periods for running flexible energy-intensive home tasks. Review your existing plan to see how these times align with your electricity consumption. Remember that actual pricing and plan details are subject to change, so be sure to check your latest PG&E bill before changing your habit.
E-ELEC
E-ELEC uses a 4 PM to 9 PM peak period and has a higher fixed monthly charge, with lower usage-based rates that may suit some households. Homes with consistently high electricity consumption, including those with an EV or other major electrical loads, may want to compare the plan carefully. What you actually pay depends on your household's consumption history, so reviewing PG&E rates and bill-saving techniques can provide context. Always check your current bill and PG&E's latest plan specifics before making any changes.
Why Peak Pricing Exists
Time-of-use pricing reflects the fact that when people use energy varies over the course of the day, with the late afternoon and nighttime often being the times of highest demand. It can cost more to produce and transport power when more households use air cooling, kitchen appliances, lighting, and electronics at the same time. Electricity peak hours vary by utility and location, so it's better to check your utility's schedule than to adopt a general rule. This pricing structure incentivizes users to shift variable electricity use to off-peak periods.
Peak hours: Electricity demand is typically higher during these periods, so usage rates are generally higher. Check your utility's specific schedule to know when peak pricing applies.
Off-peak hours: Demand is usually lower during these periods, which can result in lower electricity rates. Shifting flexible activities to these hours may help reduce usage costs.
Load shifting: Moving flexible electricity use away from peak periods. Running appliances, charging devices, or completing other energy-intensive tasks during lower-rate periods can help manage consumption.
Shifting Usage With Stored Power
If you use one appliance, it's easy to change, but it's tougher to shift the whole electricity use of a house away from the peak hours. A battery system can draw power from the grid during off-peak hours. This strategy can also take advantage of extra solar generation and may help households manage bigger evening loads. The actual savings depend on the rate differential, battery efficiency, household consumption, and how much electricity can be moved.
Heat pumps and air conditioners: These devices can use a lot of electricity, especially in extreme temperatures. Use of stored power in higher-rate hours can help to shift some of this demand.
Electric vehicle chargers: EV charging can be a substantial load for a household. Some of the electric load can be shifted away from the peak by charging at cheaper times or using stored energy.
Electric water heaters: Heating water can increase the electricity use of a home throughout the day. Where practicable, transferring heating to lower-rate periods can minimize dependence on peak hour electricity.
Kitchen appliances: Ovens, microwaves, dishwashers and other kitchen equipment can contribute to the evening load. Even running flexible appliances at earlier or later times might help spread electricity use throughout the day.
Home offices and electronics: computers, monitors, entertainment systems and other devices may stay on during peak hours. An alternative is to store power to move part of this flexible demand.
Backup Power for PG&E Peak Hours
Using stored energy during PG&E's higher-cost evening period can help households reduce their reliance on grid electricity when rates are highest. A whole-home battery system can charge during lower-cost periods and provide power later when household demand increases. For larger homes with significant evening loads, the EcoFlow DELTA Pro Ultra provides high output and expandable capacity for demanding energy needs.
The EcoFlow DELTA Pro Ultra can be useful for households that want to store electricity during lower-cost periods and use that energy during more expensive hours. It also features an expandable capacity, making it suited for residences with a higher electrical demand that needs more than what a modest portable power station can provide.
Higher-Capacity Energy Storage for Peak-Hour Loads
Some bigger homes require more stored energy and higher output to meet significant evening electricity use. This provides greater flexibility to shift energy use away from higher-cost periods, delivering the necessary capacity and output when multiple high-demand appliances run simultaneously. Designed for whole-home use where more power and more storage are needed, the EcoFlow DELTA Pro Ultra X is a powerful portable power station.
Off-Peak Hours and How Much They Actually Save
For the PG&E plans discussed here, electricity rates are generally higher during late afternoon and evening peak periods, making other hours useful for flexible loads. Running appliances such as a dishwasher or washing machine outside the peak window can move that consumption to lower-priced periods. EV charging can have a larger impact because Level 2 chargers use substantial electricity, and EV charging costs can vary significantly with TOU pricing. Solar and battery storage can also help this approach by moving solar energy generated during the day to use in the evening.
Laundry: Run washers and dryers before the peak window or later at night. Using delayed-start settings can make it easier to avoid higher-priced hours.
Dishwashing: Run the dishwasher outside the peak period when possible. A delayed-start feature can help schedule the cycle for lower-cost hours.
EV charging: Schedule EV charging during lower-cost periods whenever practical. Because Level 2 chargers can use substantial electricity, timing can have a noticeable effect on overall consumption costs.
Water heating: Use programmable settings to reduce water-heater operation during peak hours. Shifting some heating activity to lower-cost periods can help manage electricity use.
Pool equipment: Move pool-pump cycles away from the evening peak when practical. Programming the equipment to run earlier or later can reduce peak-period electricity consumption.
Choosing the Right PG&E Rate Plan
Every home is different in terms of schedules, equipment, and energy consumption, so there's not a one-size-fits-all plan or cost. Before you switch, look at several months of real usage and evaluate when your household uses the most electricity. If you have solar panels or are thinking of adding battery storage, comparing the benefits of more solar panels or more batteries for your home might help you understand how your energy setup may affect your electricity consumption. Another key point is your capacity to shift loads outside of peak hours.
Electricity usage: Review when your household uses the most electricity during the day. This can show whether a TOU plan matches your normal consumption pattern.
Evening usage: Consider how much electricity you typically use after 4 PM. Heavy evening consumption may make peak-period rates especially important when comparing plans.
EV ownership: An EV can add substantial electricity use to your monthly consumption. Check whether you can schedule charging during lower-cost hours.
Solar panels: Compare when your solar system produces electricity with when your household needs it. Daytime generation may not directly cover evening demand without storage.
Battery storage: A battery can store electricity for later use, depending on the system and setup. Consider how much of your evening demand could potentially be supplied from stored energy.
Smart controls can make load shifting easier by coordinating battery use, EV charging, and other equipment around household energy needs. Instead of manually adjusting every appliance, smart home energy management can help automate these energy decisions based on your setup. Actual savings will depend on your rate plan, electricity consumption, equipment, and how much usage can be shifted.
Conclusion
PG&E peak hours can really affect your electricity bill, especially on programs that charge more from 4 to 9 PM. When possible, move variable loads such as washing, dishwashers, and EV charging to lower-cost hours, and evaluate rate plans against your actual usage habits. For greater evening demand, residences can use stored energy as another approach to managing peak-hour electricity. EcoFlow DELTA Pro Ultra and EcoFlow DELTA Pro Ultra X can store energy for use when PG&E rates are highest.
FAQs
What time do PG&E peak hours start and end?
For the commonly referenced E-TOU-C plan, peak hours are 4 PM–9 PM every day. E-TOU-D commonly uses 5 PM–8 PM on weekdays. Other PG&E plans may have different schedules and rate periods. Check your current plan and bill to confirm the hours that apply to your household.
Are PG&E peak hours the same on weekends?
Not necessarily, because weekend schedules depend on the specific PG&E rate plan. E-TOU-C has a daily peak period that includes weekends, while E-TOU-D has a weekday peak period. Other plans may use different schedules. Check your current rate plan for the applicable weekend hours.
How much more expensive is PG&E electricity during peak hours?
The price difference depends on your specific rate plan, season, baseline allowance, and other applicable pricing rules. TOU plans generally charge higher usage rates during peak periods than during lower-priced periods. The exact difference can change over time. Review PG&E's current rate information or your latest bill for the rates that apply to you.
Which PG&E rate plan is best for solar customers?
There is no universal choice. Solar customers should compare their current generation, electricity consumption, peak usage, export credits, and current PG&E rate options. A personalized comparison is more useful than choosing a plan based only on its peak-hour schedule.
Can I switch PG&E rate plans at any time?
PG&E permits customers to alter pricing schedules, although particular rules may come into play. PG&E said some plans allow customers to switch their rate schedule twice in the first 12 months, and then they must stick with the new rate for 12 months. Please review your existing eligibility and plan rules before switching.
