Electric Vehicles

Residential-Family Dwelling

Step 1: Understand charging options

Electric vehicles may be charged at home with several options. An owner may charge the electric vehicle with a Level 1 charging cord provided with most electric vehicles plugged into common household outlet. Or, an owner may opt to purchase and install a quicker Level 2 charging station. If you choose to install a Level 2 station, a licensed electrician and a building permit may be required for any electrical work. Consult a licensed electrician to understand the installation process and impact.

For more on charging options, refer to our EV Basics page.


Step 2: Understand your electric rate options

There are several rate options for residential customers with electric vehicle. To avoid surprises, we encourage you to read about our rate options and talk to Hawaiian Electric if you are considering time-of-use rate options. Customer may contact the GoEV Team at 808-543-4638 (GoEV) or email to GoEV@hawaiianelectric.com.

Schedule R

If you remain on the standard residential rate, you can charge your electric vehicle and use your electric appliances on the same rate at any time of day. You do not have to contact your utility.

If you wish to take advantage of lower rates available during daytime, select an option below to understand the enrollment process.

Schedule TOU-RI, for whole house

Charge your electric vehicle and all other household appliances at discount rates during daytime. Please visit our Time-of-Use enrollment page for additional information on how to sign up.

Schedule TOU-RI, for EV charging only

Customers may install a second service for residential electrical vehicle charging under the TOU-RI rate while keeping their other household electric use the same. Residents who do not have an individual utility account, such as residents paying for electricity through their multi-unit dwelling, may install electric vehicle charging under their own service at their place of residence under this rate.

Customers opting for a second service must contact the GoEV Team for enrollment. A customer must also hire a licensed electrician to install the second service for EV charging only. The service cannot be completed until the permitted work is approved.

Schedule TOU EV

This rate is now closed to new enrollment.


Step 3: Consult a certified electrician

Customers may charge at home with a Level 1 charging cord plugged into a standard grounded outlet. Older homes without grounded outlets will require an electrical upgrade.

The quicker Level 2 charging station may be equipped to plug into an existing dryer outlet or may require an electrician to install the charging station or a new outlet.

Your EV manufacturer or dealer may recommend an electrical contractor. Request an estimate for any electrical work to install a new outlet, charge station, or upgrades to accommodate the second meter. Each home is different and the initial electrical expenses must be considered against the long-term benefit of the discount rate.

Your contractor will need to obtain a permit for electrical work and contact your utility to complete the installation of new service. To fully understand the potential impact of the second service under Schedule TOU-RI, consider requesting an estimate for the removal of the second service, if this becomes necessary.


Step 4: Submit enrollment form

Please visit our Time-of-Use enrollment page for additional information on how to sign up for household Schedule TOU-RI.

Please contact the GoEV Team if you are considering a separately metered service for EV charging only. Enrollment for a new separate meter needs to be approved and cannot be fully installed until required building permits are closed.


Step 5: Meter Change

Time-of-use rates require a new meter that can track energy use by time of day. The meter for a separately metered service for EV charging will be installed after all required permits are closed.
