Why utility rate design matters more than most incentives
California electricity is expensive. PG&E's tiered residential rate blends to approximately $0.44/kWh all-in — roughly 3.5x ComEd Rate BEST's ~$0.045/kWh off-peak, 5x Ameren Missouri's Overnight Savers ~$0.085/kWh, and among the highest utility rates for a major US population center. For a Bay Area EV owner charging 4,500 kWh/year (typical 15,000 mi/yr at 30 kWh/100mi), the difference between the right rate plan and the wrong one is roughly $585 annually, or nearly $3,000 over 5 years — more than California's $2,000 CCVRP base rebate delivers upfront and comparable to a full year of gas savings on the vehicle switch itself.
The federal EV tax credit expired September 30, 2025. California's CCVRP rebate remains at $2,000 for standard-income buyers with higher tiers for lower-income households. But the largest post-purchase utility economic lever available to a Bay Area EV owner is the rate choice: enroll in EV-2A and shift charging behavior to capture off-peak windows, or stay on E-1 Tiered and pay a flat rate around the clock.
PG&E's two main paths for EV owners
PG&E offers several residential rate schedules but two matter for most EV owners:
E-1 Tiered is PG&E's default residential rate. Blended supply and delivery averages approximately $0.44/kWh across typical usage tiers, with no time-of-day variation. Every kWh costs the same whether consumed at 3 AM or 5 PM on a July weekday. Simple, predictable, and expensive.
EV-2A is PG&E's dedicated EV time-of-use rate. Off-peak rates (midnight to 3 PM weekdays plus all weekend and holiday hours) run approximately $0.31/kWh. Peak rates (4-9 PM weekdays, especially in summer) exceed $0.60/kWh. Partial-peak rates (3-4 PM and 9 PM-midnight weekdays) sit between at approximately $0.40-0.45/kWh. Critically, EV-2A is a whole-house rate: the time-varying structure applies to all electricity your home consumes, not just to EV charging.
A third option, EV-B, requires a separate dedicated meter for EV charging only and is rarely offered to new customers due to metering installation complexity and cost. For practical purposes, most PG&E EV owners choose between E-1 and EV-2A.
Path 1: E-1 Tiered — the default flat rate
E-1 Tiered is the rate PG&E customers use by default unless they actively enroll elsewhere. The bill structure is straightforward: a fixed customer charge (approximately $10-$12 per month depending on service class) plus per-kWh usage rates that tier by monthly consumption — the more electricity you use, the higher the rate on incremental kWh.
For a typical EV owner, blended cost across the tiered structure averages approximately $0.44/kWh all-in. For 4,500 kWh/year of EV charging (typical 15,000 mi/yr driver at 30 kWh/100mi), E-1 produces approximately $1,980 in annual EV charging cost, or $9,900 over 5 years. This is the highest baseline against which EV-2A is measured.
E-1 is the right choice for households that cannot commit to disciplined off-peak charging or that have unavoidable weekday afternoon electricity needs (multiple people working from home, air conditioning during summer peaks, medical equipment). It is also the safer choice for buyers who are uncertain whether they can maintain the discipline EV-2A requires — more on that below.
Path 2: EV-2A — the dedicated EV whole-house rate
EV-2A is PG&E's primary EV-oriented rate structure. Time blocks vary by season (summer May-October vs winter November-April) but the general pattern is consistent:
| Time block | Hours | Approx. rate | EV impact |
|---|---|---|---|
| Off-peak | Midnight – 3 PM + weekends | ~$0.310/kWh | Target window |
| Partial-peak | 3 PM – 4 PM, 9 PM – midnight weekdays | ~$0.400/kWh | Moderate; below E-1 |
| Peak | 4 PM – 9 PM weekdays | ~$0.600/kWh | Punishing; avoid all usage |
Two features distinguish EV-2A from every other utility rate covered in the Drive Economics library. First, the off-peak window is unusually generous: 15 weekday hours (midnight-3 PM) plus all weekend and holiday hours. A driver who commutes from home during off-peak hours and returns after 9 PM can charge at off-peak rates through the entire evening and overnight. Second, the peak rate is the highest in the library at approximately $0.60/kWh — nearly 40% above E-1 Tiered's blended rate. Weekday afternoon electricity usage on EV-2A is dramatically more expensive than staying on E-1.
The whole-house implication cannot be overstated. Air conditioning, cooking, laundry, dishwasher runs — any household electricity consumption during the 4-9 PM weekday peak carries the punishing peak rate. For homes with unavoidable afternoon usage (particularly summer AC), the peak exposure risk can offset EV-2A's off-peak savings entirely.
The break-even math: when does EV-2A actually pay back?
Unlike PG&E's peer utilities where the rate choice is essentially always favorable (Rate BEST always beats standard on ComEd, Overnight Savers always beats standard on Ameren for any discipline level), EV-2A requires meaningful discipline to deliver value. The chart shows the analysis under three scenarios: E-1 Tiered as baseline, EV-2A with 100% disciplined off-peak charging, and EV-2A with 20% peak leakage (a realistic risk scenario for imperfect automation).
The break-even discipline threshold is approximately 55% off-peak charging. Below 55%, EV-2A can actually cost more than E-1 Tiered. Above 55%, EV-2A saves money — with savings growing to approximately $585 annually at 15,000 mi/yr with full discipline, or $2,925 over 5 years. Even at 20% peak leakage (a realistic worst-case for typical automated households), EV-2A still saves approximately $1,620 over 5 years compared to E-1.
The maximum theoretical savings under EV-2A at 25,000 mi/yr with full discipline reach $975 annually. This is comparable to the total annual gasoline cost for a comparable ICE vehicle at 32 MPG combined and $5.15/gallon Bay Area gas — the rate choice alone matches the fuel savings of the EV switch itself.
Discipline is meaningful in practice. Automated smart chargers with scheduling can lock EV charging to off-peak windows reliably, but whole-house peak exposure is harder to eliminate. Households with AC running during summer 4-9 PM windows face material peak-rate exposure that cannot be scheduled away. The realistic PG&E EV owner should model themselves at 10-20% peak leakage rather than 0%.
Which path should you choose?
The EV-2A vs E-1 decision reduces to a single question: can you keep total household electricity usage during the 4-9 PM weekday peak below 20% of daily consumption? Four practical characteristics determine which rate produces the best outcome:
- Do you have a Wi-Fi-enabled Level 2 charger with schedule enforcement? If yes: EV-2A becomes viable because your EV charging alone can be reliably locked to off-peak windows. If no: enrolling in EV-2A without scheduled charging is genuinely risky — stay on E-1 or add a smart charger first.
- Do you have summer air conditioning that runs during 4-9 PM weekday afternoons? If no (natural cooling, nighttime AC pre-cooling, no AC): EV-2A is much more attractive because your household peak exposure is minimal. If yes and heavy: consider EV-2A only if you have solar with battery, or accept that peak AC usage will absorb much of your EV charging savings.
- Is anyone home cooking dinner, running appliances, or working from home during 4-9 PM weekdays? If no (empty house, minimal usage): EV-2A works cleanly. If yes and consistent: model your realistic peak leakage carefully; you may be in the 20-30% range that materially compresses EV-2A savings.
- Are your driving patterns such that most of your charging happens overnight or on weekends? If yes: EV-2A is the right choice because the off-peak window generously covers your natural charging pattern. If your household regularly needs afternoon top-up charging (multiple EVs, high mileage, opportunistic charging): peak exposure risk grows and E-1 becomes competitive.
The default recommendation for most Bay Area EV owners with home Level 2 charging and manageable peak-hour household usage: EV-2A. The generous off-peak window is easy to hit for typical charging patterns, and the plan's tolerance for modest peak leakage means the analysis remains favorable even for imperfect households. E-1 remains the safer choice for high-AC homes or households unable to manage peak-hour electricity usage.
The California solar complication: NEM 2.0 vs NEM 3.0
Home solar changes PG&E EV economics substantially, but the direction and magnitude depend on when the solar system was installed. California's net metering regime shifted in April 2023 from NEM 2.0 to the Net Billing Tariff (commonly called NEM 3.0), and the two produce dramatically different outcomes for EV owners.
NEM 2.0 (solar installed before April 2023, grandfathered for 20 years from install date): Solar exports credited at full retail rate — approximately $0.31-$0.44/kWh depending on the customer's rate schedule. For an EV owner, this means daytime solar generation directly offsets EV charging cost dollar-for-dollar. A NEM 2.0 solar customer with adequate rooftop capacity can theoretically zero out EV charging costs entirely by exporting solar during the day and importing at night for EV charging at the same effective rate.
NEM 3.0 (solar installed April 2023 onward): Solar exports credited at avoided cost rates — approximately $0.05-$0.10/kWh, dramatically lower than retail. Battery storage becomes essential for solar economics. For an EV owner without a home battery, NEM 3.0 solar provides value only when solar generation is consumed directly during the day — not when exported. This favors EV owners who work from home and can charge their EV during daytime solar hours, penalizes commuters who need to charge at night from grid electricity while their daytime solar exports at avoided cost.
What this means practically: A NEM 2.0 EV owner on EV-2A with sufficient solar capacity can achieve near-zero net EV charging cost. A NEM 3.0 EV owner on EV-2A without a battery captures perhaps 30-50% of the theoretical solar benefit. Adding a home battery ($10,000-$15,000 net after federal tax credit and California SGIP incentives, if available) restores most of the NEM 2.0 economics by allowing daytime solar generation to be stored and used for evening EV charging at retail-rate value.
For buyers considering solar-plus-EV combinations, the NEM 3.0 shift has fundamentally changed the calculus. The Menlo Park Lucid case excludes home solar from its base case because the analysis becomes highly household-specific under NEM 3.0. Buyers evaluating solar+EV should model both scenarios explicitly with their own rooftop, battery, and consumption patterns.
See it in our case studies
The Menlo Park Lucid Air Pure vs BMW 540i xDrive case shows PG&E EV-2A economics in practice with a real buyer scenario:
Aditi is a Menlo Park tech VP driving 15,000 miles per year. She has 15-hour weekday off-peak windows (midnight-3 PM) plus all weekend hours available for EV charging. She keeps her AC minimal during peak hours by pre-cooling overnight. This puts her charging pattern very close to full-discipline EV-2A: essentially 100% off-peak.
In her case, EV-2A produces approximately $585 in annual EV charging savings compared to E-1 Tiered. Over 5 years, that's $2,925 in charging cost avoidance — more than the $2,000 CCVRP rebate delivers upfront. The Lucid Air Pure's $11,270 5-year cash advantage over the BMW 540i xDrive under EV-2A shrinks by approximately $2,500 if she defaults to E-1 Tiered instead. Rate discipline is the single largest utility-side lever in her comparison.
The case also demonstrates that in Aditi's specific situation — no home solar, minimal peak AC exposure, disciplined overnight charging — EV-2A delivers close to its theoretical maximum savings. Buyers with less favorable household patterns should expect meaningfully lower savings than her scenario implies.
How this compares to peer utility EV plans
PG&E EV-2A sits at the high-cost end of the utility EV rate spectrum, but its off-peak window is unusually generous:
| Utility / rate | Off-peak rate | Off-peak window | Fixed monthly charge |
|---|---|---|---|
| PG&E EV-2A | ~$0.310/kWh | 15+ hrs (midnight-3 PM + weekends) | None |
| SDG&E EV-TOU-5 (Southern CA) | ~$0.170/kWh | 6 hrs (midnight-6 AM) | $16.00 |
| SCE TOU-D-PRIME (Southern CA) | ~$0.260/kWh | 8 hrs (8 PM – 4 AM) | $24.00 |
| Ameren MO Overnight Savers | ~$0.085/kWh | 8 hrs (11 PM – 7 AM) | None |
| ComEd Rate BEST | ~$0.045/kWh | 9 hrs (9 PM – 6 AM) | None |
Rates are approximate and reflect published tariffs as of publication.
Three observations. First, PG&E EV-2A's off-peak rate is nearly 7x higher than ComEd Rate BEST — California electricity is genuinely expensive by any comparison. Second, the 15-hour weekday off-peak window is the most generous in the library, which matters enormously for real-world discipline: it is much easier to hit "off-peak charging" when off-peak covers most of the day. Third, PG&E charges no fixed monthly EV rate premium (unlike SCE's punishing $24/month TOU-D-PRIME charge or SDG&E's $16/month EV-TOU-5 charge). Low-mileage EV owners in PG&E territory face no threshold-to-cross before EV-2A starts saving money.

Rate figures reflect PG&E published tariffs as of September 2026 and are approximate. E-1 Tiered blended rate of ~$0.44/kWh represents combined supply and delivery all-in for typical Bay Area residential usage across tier boundaries. EV-2A off-peak of ~$0.31/kWh assumes 100% disciplined charging within midnight-3 PM weekday and all-weekend windows. Partial-peak and peak rates vary by season (summer May-October vs winter November-April) and by usage tier; peak rates of ~$0.60/kWh reflect summer 4-9 PM weekday exposure.
