The situation
Elena is 41, a product designer at a Pasadena startup, and commutes 15 miles each way to the office three days per week. Annual mileage runs about 12,000. She's replacing a 2019 Toyota RAV4 and has narrowed her choice to two: the 2026 Hyundai Ioniq 5 SE Standard Range at $35,250 and the 2026 Hyundai Tucson Hybrid Blue at $32,800 — same brand, adjacent showrooms, $2,450 apart at sticker.
Three things about Los Angeles shape the analysis. First, gas at $5.69/gal is the highest documented in the library. Second, SCE offers three distinct residential rate pathways with counterintuitive economics: the marketed EV rate (TOU-D-PRIME) carries a $24/month grid service charge that offsets much of its off-peak discount; the Default TOU plan has no fixed charge and lower off-peak rates for typical EV consumption; a legacy tiered plan sits between. Third, California's Clean Vehicle Rebate Project (CCVRP) offers $2,000 at Elena's income tier, and the federal $7,500 credit expired September 30, 2025.
The question this case explores is: which SCE rate plan actually produces the best EV economics, and how much does that choice matter compared to the vehicle choice itself?

Break-even: when the Ioniq 5 pays back its premium
The Ioniq 5 costs $1,800 more than the Tucson Hybrid upfront (net of CVRP rebate and charger install). Charting cumulative cost year-by-year shows exactly when that premium is recovered under each SCE rate plan.
Under Default TOU the Ioniq 5 crosses below Tucson at about 25 months. Under the marketed TOU-D-PRIME EV rate, the crossover takes 34 months — nearly a year longer. This visually confirms the case's counterintuitive finding: SCE's branded "EV rate" is actually slower to pay back than the plan they'd otherwise put you on by default. The $24/month TOU-D-PRIME grid service charge is the culprit.
The 5-year math
Two scenarios shown side-by-side, both under disciplined off-peak charging. Scenario 1 uses SCE TOU-D-PRIME (the plan SCE markets to EV owners) with its $24 monthly fixed charge. Scenario 2 uses SCE TOU-D-4-9PM (the default plan most SCE customers are auto-enrolled in) with no EV-specific fixed fee. Both use actual LA retail gas at $5.69/gallon. Tiered Schedule D is discussed as a third option in the sensitivity section below.
| TUCSON HYBRID | IONIQ 5 (TOU-D-PRIME) | IONIQ 5 (Default TOU) | |
|---|---|---|---|
| Purchase | $32,800 | $35,250 | $35,250 |
| CCVRP base rebate | — | –$2,000 | –$2,000 |

| Energy (5-yr) | $8,984 $5.69/gal actual | $4,056 $0.26/kWh off-peak | $4,368 $0.28/kWh blended |
| Utility fixed charges (5-yr) | — | $1,440 $24/mo TOU-D-PRIME | — |
| Maintenance (5-yr) | $3,000 | $2,300 | $2,300 |

Assumptions: Los Angeles gas $5.69/gal (AAA verified 2026-09-02); SCE TOU-D-PRIME off-peak $0.26/kWh plus $24/month grid service charge; SCE Default TOU blended $0.28/kWh; Ioniq 5 SE efficiency 30 kWh/100mi (EPA); Tucson Hybrid Blue 38 MPG combined (EPA); CCVRP base rebate $2,000 applied; federal EV credit zero (expired September 30, 2025); insurance and maintenance from category baselines.

What the analysis reveals
SCE's rate plan choice matters more than the vehicle choice. The Ioniq 5 wins under all three SCE rate pathways, but the win margin varies by a factor of two: $1,388 under TOU-D-PRIME (the marketed EV rate), $1,890 under legacy tiered, and $2,516 under Default TOU. Elena's decision about which rate plan to enroll in is a $1,128 decision over 5 years — nearly the entire cash advantage of the EV itself.
The marketed EV rate is the worst of the three. This is counterintuitive and worth naming plainly. SCE promotes TOU-D-PRIME as the rate designed for EV owners, but its $24/month grid service charge ($1,440 over 5 years) offsets nearly all of its off-peak discount for a 12,000 mi/yr driver. Only extremely high-mileage EV owners (25,000+ mi/yr) benefit enough from the off-peak rate to overcome the fixed charge. For typical mileage, Default TOU is the better choice — no active enrollment required.
Gas price does most of the analytical work. At $5.69/gallon, the Tucson Hybrid's 38 MPG combined produces $8,984 in 5-year fuel costs. The Ioniq 5 at 30 kWh/100mi under Default TOU produces $4,368 in electricity costs. That $4,616 fuel differential is the largest single line item in the analysis and would grow further if gas rises above $6. Below $4.50, the analysis tips back toward the Tucson Hybrid on cash.
The generalizable finding: rate design determines EV outcomes in California. Cases in the library from other regions (Chicago, Columbus) show cleaner EV wins because utility rate structures are simpler and don't punish EV owners with fixed charges. California's rate complexity means buyers must actively evaluate their utility's plan options; defaulting to the "EV rate" without doing the math can cost more than choosing no EV rate at all.
What could shift the analysis
- Higher CCVRP tier eligibility expands the EV advantage. Elena qualifies at the base $2,000. Households at moderate income tiers receive up to $7,500 in CCVRP. At $7,500, the Ioniq 5 wins by $6,900+ under Default TOU — shifting from bubble to decisive.
- Federal EV credit reinstatement flips the analysis decisively. The expired $7,500 federal credit would drop the Ioniq 5's effective price to $27,750 — below the Tucson Hybrid. The EV wins by $9,000+ in that scenario. Unpredictable political variable.
- Summer peak charging exposure hurts both TOU plans meaningfully. SCE's summer peak windows (4-9 PM weekdays, June-October) charge $0.50+/kWh. Even 15% inadvertent peak charging adds $850 over 5 years and closes most of the Default TOU advantage. Smart charger scheduling essential.
- Higher mileage amplifies the fuel-cost advantage. At 15,000 mi/yr Elena's Ioniq 5 advantage grows to $3,900 under Default TOU. At 20,000 mi/yr it reaches $5,700. TOU-D-PRIME only becomes competitive with Default TOU above 25,000 mi/yr, where its off-peak discount overcomes the $24/month fixed charge.
- Gas price volatility swings the outcome by $1,000+/year. LA metro gas has ranged $4.50 to $6.20 over 24 months. Sustained prices above $6 push the analysis decisively toward the Ioniq 5; below $4.50 the Tucson Hybrid wins on cash. Buyers should form a view on 5-year gas trajectory before deciding.
