PG&E Time-of-Use Rates: A Plain-English Guide to Saving
PG&E’s peak hours are 4–9 p.m. on most plans, every day of the week including weekends. The exception is E-TOU-D, whose peak is 5–8 p.m. on weekdays only.
On EV2-A, summer off-peak power costs about 23¢/kWh against about 54¢/kWh at peak. That gap is the entire opportunity: you are not using less energy, you are buying the same energy at a different price.
This guide breaks down each PG&E plan, what its peak window actually costs, and the two ways to capture the difference.
How PG&E time-of-use pricing works
PG&E’s plans all share one idea: an expensive peak period in the evening, and cheaper energy the rest of the day. The plans differ in exactly when peak falls, how steep it is, and whether they carry a partial-peak “shoulder” price between off-peak and peak. The numbers below are the below-baseline summer prices effective March 1, 2026 (confirm your current numbers on PG&E’s rate plan pricing sheet, since they vary by baseline allowance and season):
Each plan’s shape is below. The bars are what a kilowatt-hour costs at each hour of the day, and the seasons switch with the control above them.

E-TOU-C — peak 4–9 p.m. every day
Off-peak runs around 32¢/kWh and peak around 44¢. This is the default plan for most households, and its peak applies seven days a week.
E-TOU-D — peak 5–8 p.m. weekdays only
Weekends are entirely off-peak. Off-peak around 34¢, peak around 48¢. The narrower window and the weekend exemption are the trade for a steeper peak price.
E-ELEC — peak 4–9 p.m., built for all-electric homes
The Electric Home plan, for homes with a heat pump, EV, or battery. Off-peak (midnight–3 p.m.) around 33¢, a partial-peak shoulder (3–4 p.m. and 9 p.m.–midnight) around 39¢, and peak (4–9 p.m.) around 55¢. It also carries a fixed monthly Base Services Charge in exchange for lower per-kWh prices, so it pays off for larger all-electric loads.
EV2-A — peak 4–9 p.m., the standard EV plan
Off-peak (midnight–3 p.m.) around 23¢, partial-peak around 43¢, and peak (4–9 p.m.) around 54¢. The overnight off-peak rate is among the lowest of the residential plans.
EV-B — peak 2–9 p.m., the older EV plan
Closed to new whole-home enrollment in most cases, but still active for many households. Its peak is a wide 2–9 p.m. window at around 62¢, with partial-peak (7 a.m.–2 p.m. and 9–11 p.m.) around 38¢ and off-peak (11 p.m.–7 a.m.) around 26¢. The long peak makes automated load-shifting matter even more.
The pattern is the same everywhere: the grid is busiest in the early evening, so that’s when power costs the most.
Summer vs. winter: the prices shift twice a year
Every PG&E time-of-use plan runs two seasons, and the switch is automatic on your bill:
- Summer — June 1 through September 30. Peaks are at their highest, because air-conditioning across the state hits hardest on hot evenings.
- Winter — October 1 through May 31. Every plan drops, and the peak-to-off-peak gap narrows.
The winter discount is real. On E-ELEC, the 4–9 p.m. peak falls from about 55¢ in summer to about 32¢ in winter — and off-peak drops from 33¢ to 28¢. E-TOU-C peak goes from 44¢ to 32¢; EV2-A peak from 54¢ to 41¢; EV-B peak from 62¢ to 44¢. E-TOU-D is the one exception where the off-peak rate is slightly higher in winter (35¢ vs. 34¢) even as its peak falls from 48¢ to 39¢.
Two things follow. First, the shape of the day is flatter in winter, so the payoff from shifting a given load shrinks slightly, but it doesn’t disappear. Especially on the plans with a steep peak (E-ELEC, EV-B), it’s still worth automating year-round. Second, and more important: because summer and winter prices are different, the optimal schedule is different too. A pre-cool plan tuned for a 55¢ summer peak is over-aggressive against a 32¢ winter peak. Getting this right by hand means re-tuning twice a year; automation just uses whichever season’s prices apply on the day it’s scheduling.
Where the savings are
The savings come from shifting flexible loads out of peak and into the cheaper hours:
- EV charging. On EV2-A, charging a 40 kWh top-up during the midnight–3 p.m. off-peak instead of the 4–9 p.m. peak is roughly $9 versus $22 for the same charge. Set it and forget it, and that’s money saved every night.
- Cooling and heating. If your HVAC does most of its work before 4 p.m. and the house coasts through the evening, you move a large block of usage into off-peak.
- Water heating, laundry, dishwashing outside the peak window — small per-load, easy to automate.
You’re not necessarily using less energy. You’re using it when it’s cheap.
How to capture it: by hand vs. automatically
By hand, you’d pre-cool in the afternoon, schedule the EV charger to start late, and keep big appliances out of the 4–9 p.m. (or 5–8 p.m.) window. It works, but it’s a daily decision, and the right amount of pre-cooling depends on tomorrow’s weather. On a mild day you over-cool and waste money; on a hot one you under-prepare and pay peak rates anyway.
Automatically removes the guesswork. Hungry Machines generates a fresh schedule for your HVAC, EV charger, water heater, and battery each night. It weighs PG&E’s rate plan, the next day’s forecast, and a custom model of how your home actually holds temperature. It pre-cools just enough to coast through peak and times your EV and water heater for the cheapest hours. You set the comfort and charge limits; it does the scheduling.
For homes with an EV or central HVAC, that typically means 10–25% off the bill with no change in comfort.
If you drive electric, Hungry Machines for California EV owners works through which plan fits and what an overnight charge costs on each. For the mechanics of pre-cooling, and why it needs a model of your house rather than a rule about the clock, see automating your HVAC for time-of-use savings.
Do peak rates apply on weekends?
On every PG&E plan except one, yes. E-TOU-C, E-ELEC, EV2-A and EV-B all apply their peak window seven days a week — a Saturday at 6 p.m. is priced exactly like a Tuesday at 6 p.m.
E-TOU-D is the exception. Its 5–8 p.m. peak runs on weekdays only, and Saturday and Sunday are entirely off-peak. That is the plan’s whole design: a steeper weekday peak (around 48¢ against E-TOU-C’s 44¢) traded for two completely cheap days.
So the answer decides which plan suits you. If your household does its laundry, EV charging and cooking on weekends, E-TOU-D hands you those hours at the off-peak rate and the arithmetic is straightforward — 20 kWh of weekend load that would cost about $8.80 in an E-TOU-C peak costs about $6.80 off-peak on E-TOU-D. If your usage is flat across the week, E-TOU-C’s lower peak price is usually the better deal, and the weekend distinction is worth nothing to you.
Confirm which plan you are on before assuming either way — it is printed on your bill, and the current numbers are on PG&E’s rate plan pricing sheet.
Common questions
Which PG&E plan is best for an EV?
EV2-A is the current purpose-built plan — the overnight off-peak rate is among the lowest of the residential plans, which rewards charging while you sleep. The bigger your nightly charge, the more it matters. If you’re on the older EV-B, its off-peak rate is comparable but its peak stretches all the way from 2 to 9 p.m., so keeping the car (and other big loads) out of that seven-hour window is worth even more. And if your whole house is electric — heat pump plus EV plus maybe a battery — E-ELEC can beat both, since it trades a fixed monthly charge for lower per-kWh energy prices. Which one wins depends on your total usage; the honest answer is to compare on PG&E’s rate comparison tool.
Is E-TOU-D better because weekends are off-peak?
It can be, and the arithmetic is checkable. E-TOU-D’s peak is 5–8 p.m. on weekdays only, so Saturday and Sunday price entirely off-peak at about 34¢. The trade is a steeper weekday peak — roughly 48¢ against E-TOU-C’s 44¢ — and a slightly higher off-peak rate.
So it turns on where your usage actually sits. A household that does laundry, cooking and EV charging at weekends comes out ahead: 20 kWh of Saturday load costs about $6.80 on E-TOU-D versus about $8.80 in an E-TOU-C peak. A household whose usage is flat across the week pays E-TOU-D’s higher weekday peak for a benefit it never collects.
Pull a month of hourly data from your PG&E account before switching. The “best” plan is a fact about your household, not about the plan — and automation makes whichever one you’re on perform closer to its best case.
Do I need solar to benefit?
No. Time-of-use savings come from when you draw grid power, and that is true with or without panels on the roof. On EV2-A the spread between the midnight–3 p.m. off-peak (around 23¢) and the 4–9 p.m. peak (around 54¢) is more than double, and nothing about that gap requires solar to capture.
Solar does change the shape of the problem. It tends to cover your midday load already, which means the remaining opportunity concentrates in the evening peak and the overnight hours — exactly where a battery or a well-timed EV charge does its work. Under NEM 3.0, export credits are low enough that self-consuming your production usually beats selling it, which makes load-shifting more valuable to solar owners, not less.
Either way, the lever is the same: move flexible load into the cheap hours.
What are PG&E’s peak hours?
It depends on the plan, and the plan is printed on your bill. On E-TOU-C, E-ELEC and EV2-A, peak is 4 to 9 p.m. every day of the week. On E-TOU-D, peak is 5 to 8 p.m. on weekdays only, and weekends are entirely off-peak. On the older EV-B plan, peak stretches from 2 to 9 p.m. E-ELEC and EV2-A also carry a partial-peak shoulder either side of the peak (3 to 4 p.m. and 9 p.m. to midnight), priced between off-peak and peak. Every plan runs a summer season from June through September, when the peak price is highest, and a winter season from October through May, when every price drops but the windows stay the same. If you remember one number, remember 4 to 9 p.m.: that is the window on the default plan and on the standard EV plan.
What is PG&E’s off-peak rate per kWh?
Summer below-baseline off-peak prices effective March 2026 are roughly: E-TOU-C about 32¢/kWh, E-TOU-D about 34¢, E-ELEC about 33¢, EV2-A about 23¢, and EV-B about 26¢. Winter off-peak is lower on every plan except E-TOU-D, where it edges up to about 35¢ while the peak falls. EV2-A has the cheapest off-peak of the residential plans, which is why it rewards overnight EV charging so well: its 23¢ off-peak against a 54¢ peak is more than a two-to-one gap. Your exact number depends on your baseline allowance, the season and whether you buy generation from PG&E or a community choice aggregator, so confirm it on PG&E’s rate plan pricing sheet before doing any arithmetic with it.
When is the cheapest time to use electricity on PG&E?
Overnight and, on the EV and electric-home plans, most of the day. On EV2-A and E-ELEC the off-peak window runs from midnight to 3 p.m., fifteen hours at the lowest price, so laundry, the dishwasher and EV charging are all cheapest anywhere in that stretch. On EV-B the cheap hours are 11 p.m. to 7 a.m. On E-TOU-C and E-TOU-D, everything outside the peak window is off-peak, so the cheapest time is any hour before 4 p.m. or after 9 p.m. (before 5 or after 8 on E-TOU-D, and all weekend). The most expensive hour on every plan is the early evening, so the single habit that saves the most is starting the dryer, the dishwasher and the car charger after 9 p.m. or before the afternoon.
What is PG&E’s E-TOU-C plan?
E-TOU-C is PG&E’s default residential time-of-use plan, the one most households are on unless they chose another. Its peak is 4 to 9 p.m. every day of the week, weekends included, and everything else is off-peak. In summer the below-baseline prices are about 32¢/kWh off-peak and about 44¢ at peak; in winter the peak drops to about 32¢. It has no partial-peak shoulder and no super-off-peak tier, which makes it the simplest plan to plan around and also the one with the smallest spread. If you have an EV or a heat pump, EV2-A or E-ELEC will usually beat it, because their off-peak prices are lower even though their peaks are higher. Compare on PG&E’s rate comparison tool with a month of your own hourly data.
