Energy rates
The charged price is the base rate plus its adjustment. Adjustments carry fuel
and rider costs and are frequently most of the bill, so a comparison built on the base
rate alone is meaningless.

The utility's own description
The Electric Vehicle Charging Separate Meter rate (R-EV SM) is an optional residential rate for customers with a separate meter installed for the sole purpose of charging one or more electric vehicles. Customers choosing Rate R-EV SM will pay the Time of Day charges in Rate R TOD for all Peak kilowatt hours recorded on the second meter but will pay a lower variable rate for all Off-Peak and Super Off-Peak kilowatt hours recorded on the second meter. The Power Cost Adjustment Clause, the Underground Utilities Charge and the CMLP Rules and Regulations are incorporated by reference as a part of this rate schedule. This rate schedule is applicable to all electric service required by individual (single family) private residences, condominium units, condominium common area facilities and individually metered apartment units exclusively for electric vehicle charging for domestic purposes, measured using a separate, secondary meter. This rate schedule is not applicable to businesses, licensed boarding or rooming houses, fraternity or sorority houses advertised as such, educational institutions or facilities, apartment houses including the common facility requirements, or the common facility requirements of residences also used for business purposes, evidenced by any form of advertising, which will be served under the appropriate general service rate schedule
