Cost to charge an EV at home on SRP
Pick your car, how far you drive and when you plug in. On SRP's open time-of-day plans the cheapest hours are 8 a.m.–3 p.m., so midday charging costs far less than charging when you get home in the evening.
$22 a month on Electric Vehicle Price Plan (E-29)278 kWh a month for 1,000 miles, including about 10% charging losses; the same miles in a 28 mpg gas car cost about $121 a month.
| Plan | Winter / month | Summer / month | Summer peak / month | Per year | Per 100 miles |
|---|---|---|---|---|---|
| Electric Vehicle Price Plan (E-29) — closed to new customers | $22 | $22 | $22 | $266 | $2.22 |
| Manage Demand 5–10 p.m. and Save (E-16) | $28 | $28 | $28 | $332 | $2.76 |
| Basic (E-23) | $31 | $34 | $39 | $396 | $3.30 |
| Conserve 6–9 p.m. and Save (E-28) | $38 | $42 | $36 | $466 | $3.88 |
This is the extra cost of charging: your estimated bill with the EV minus your bill without it, so it includes changes in the Manage Demand plan's demand charge. Taxes and fees are not included.
Cost per 100 miles at SRP prices

Tips
- Set a charging schedule in your car or charger so it never starts during on-peak hours.
- If your car is home during the day, 8 a.m.–3 p.m. is the cheapest window on Conserve 6–9 p.m. and Save and on Manage Demand.
- On Manage Demand (E-16), charging between 5 and 10 p.m. on a weekday also raises your demand charge.
- Still on the closed Electric Vehicle plan (E-29)? Its cheapest hours are 11 p.m.–5 a.m. It ends by the November 2029 billing cycle.
