Reference site: 8 Tesla V4 stalls at 235 kWh/stall/day (57,183 kWh dispensed per month), a 150kW per-stall demand assumption, the model's default time-of-use mix, and a 12% loss gross-up — identical to the full utility ranking, where this tariff sits at position 43 of 86.

The rest of the California picture

The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in California covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.
