Eligibility / billing boundary: The EV plan requires an EV. The energy-rate examples exclude the separate basic service charge, adjustors, taxes, fees and any applicable Grid Access Charge.

The state average is a benchmark, not a substitute for this tariff. A low or high encoded period is a marginal energy price and should not be interpreted as a complete monthly bill unless the page explicitly says whole-bill modeling is supported.
