Electric vehicles (EVs) cost less to fuel, leave the atmosphere cleaner and help make us energy independent without compromising comfort safety or performance. As the only vehicles that produce zero tailpipe emissions, EVs make environmental sense.


decades of expertise

​Our EV expertise dates back to the 1960s when we were the first utility to commercialize quick-charging capabilities, reducing charging time from hours to minutes. We remain committed to helping EV owners get up to speed and safely plugged in.

 

ev time-of-use plan

In 2011, the Arizona Corporation Commission approved a residential time-of-use plan to support customers purchasing EVs. The three-year pilot lets you save money by charging your EV at night and other times of low demand. We’re working with EV owners to study how and where you prefer to charge your car.

Results based on driving 400 miles/week, every week. (70 miles per weekday, 25 on Saturday and Sunday. source
Combined Advantage rates include a demand charge. The yearly cost range reflects zero impact on demand to a 6.6 kW demand increase.
The ET-EV rate will be available until December 31, 2014. This rate that may be discontinued after the research period is complete. ​

thinking about buying an ev?
If you’re thinking about buying a plug-in EV, you’ll want to consider the electric impact on your home or business.
Some things to consider:
 
  • plug-in hybrid or battery electric car
  • how much you drive on a typical day
  • whether your home’s electrical panel and wiring are configured for charging your car battery
  • the best service plan for charging your car
  • the best time of day to charge your car
  • whether you need to hire a contractor or secure permits for any electrical upgrades

common terms

Our list of common terms will help you navigate the language of electric vehicles.

electric vehicle (ev)
a vehicle using a battery charged solely by the electric grid
 
hybrid electric vehicle (hev)
a vehicle that combines a battery recharged by a combination of dynamic braking with a traditional internal combustion engine
 
internal combustion engine
a traditional gas-powered vehicle
 
plug-in hybrid electric vehicle (phev)
an HEV that also can have its battery recharged from the grid
 
time-of-use service plan
an electric service plan designed to reward customers for shifting electric use away from times of peak demand, encouraging EV charging at night
 
vehicle-to-building (v2b)
a concept encouraging use of a vehicle’s battery as a source of back-up power or offset to a building’s electric load
 
kilowatt (kW)
a standard measure of electricity usage: 1kW = 1,000 watts; a typical home uses 5 to 6 kW of power on peak days
 
alternating current (ac)
a type of electric flow that periodically changes direction; electrical outlets in a typical U.S. home are AC.
 
direct current (dc)
a direct flow of electric charge
 
electric vehicle supply equipment (evse)
a power control station or equipment required to charge an EV
 
level 1 charge
basic charging type using a standard household plug (120 volts AC, 15-20 amp circuit); charging typically takes 8 to 12 hours at 1 to 2 kW of peak demand
 
level 2 charge
240 volts AC, 40 amp circuit charging station; charging typically takes 4 to 6 hours at 6 to 8 kW of peak demand (expected to be the primary residential application)
 
level 3 charge or dc fast charge
480 volts AC, three-phase service where 50% of a battery can be recharged within 10 to 15 minutes, up to 200 kW of peak demand.
 
ev initiatives
From supporting the installation of charging stations throughout Arizona to helping you locate and install your own charging station, we are committed initiatives promoting the adoption of EVs.
