Time of Use Rates (Overview)
Time of Use (TOU) rates are designed to encourage customers to use electricity at times
where the electrical system is typically less stressed.
Peak is typically between 2PM to 9PM. Off peak is typically between midnight to 7AM. Part
peak would be the other hours.
Illustrative example of the typical load on PG&E’s system and some potential possibilities for TOU rates and smart charging.

A Brief Overview of Rates and Service Planning
PG&E Residential EV Rates
Residential Rates
• PG&E PEV customers may select one of the residential PEV TOU rates (E-9A or E-9B)
or may stay on their existing residential rates (E-1, E-6).
• Whole House Option (E-9A): Serves an entire house load and PEV through a single
meter.
• Dedicated Meter Option (E-9B): Utilizes a second meter and dedicated breaker that
serves only the PEV load.
• Requires electrical construction to install panel.
• Advantage of having a separate baseline.
• PG&E has proposed new PEV TOU rates and is awaiting CPUC approval.
Non-Residential Rates
Currently no PEV rate options for customers interested in non-residential charging;
customers must be placed on one of the general commercial rate schedules.
