Drive Electric with a Great Rate Plan
Get more value from your Electric Vehicle (EV) and other clean energy tech with TOU-D-PRIME.
- If you charge your EV at home when rates are lowest—between 8 a.m. and 4 p.m.—it’s roughly equivalent to a gas-powered driver paying less than $2 for a gallon of gasoline.
- This Time-Of-Use (TOU) rate plan has the same periods as TOU-D-4-9PM, and although it has a higher fixed daily basic charge compared to other TOU rates and no baseline credit, it does offer lower kilowatt hour rates, so it is ideal for customers who tend to use more energy.
- To enroll in TOU-D-PRIME, you must attest that you’re eligible and have an electric vehicle or other qualifying equipment.

Customers who have or install a second meter at their household for charging their EV will qualify for a monthly “EV Meter Credit” on their bill to offset basic charges associated with that second meter. Monthly credit for eligible participants does not go into effect until October 2022.

- Electric or plug-in hybrid vehicle owners and lessees
- Households with residential batteries
- Households with electric heat pumps for water or space heating
