Eligibility / billing boundary: Rocky Mountain Power Utah Schedule 1 Time-of-Use energy charges are encoded from the current official rate page. The plan requires a 12-month commitment; fixed/customer charges and unrelated bill items are not allocated to marginal EV charging.

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.
