What You Need to Know About EV Charging with SPU
If you’ve already purchased an EV – or are just wanting to learn more about how it works – you’ve come to the right page.
The following information will help you decide if SPU’s EV Charging “Rate” is right for you.
Important Notice Before You Get Started: SPU’s Residential EV Charging Rate Requires You to Hire an Electrician.
– a new electric panel (breaker box),
– a new meter socket on the outside of your residence,
– and new wiring from the charger to the breaker box to the meter socket
Rates are less expensive during designated periods of time and more expensive outside of these windows of time. Without a separate meter and necessary wiring all of your electric usage would be billed as time-of-use.
That’s why the time-of-use rate is only offered for EV Charging. Charging your EV overnight is practical and works with most people’s routines.
In order to separate your EV charging usage from your standard electric usage
– the EV charger cannot be wired from or through your existing electrical panel (breaker box), and
– the EV meter cannot be wired to follow your existing house (electric) meter. A separate meter socket is required.
Note: When using your existing meter for EV charging, you will not be able to identify what is “charging usage” vs “normal usage”. It is not broken out. You will simply see an overall increase in your kWh usage on your billing statement for the additional charging usage.
– Between 10:00 p.m. and 8:00 a.m. your EV Charging Rate is only $0.057/kWh*
– Be sure these hours will work with your desired charging schedule – charging on the EV Meter outside these hours is $0.25/kWh*
*Service charge, power cost adjustment, relocation underground and conservation program charge are applicable to your monthly billings. See SPU Electric Rates.
