Tucson Electric Power is rolling out two new pricing plans next year for owners of battery and plug-in hybrid electric vehicles (EVs), offering the lowest power supply charges overnight, seven days a week.

With our Time-of-Use EV and Demand Time-of-Use EV pricing plans, EV owners can save money by shifting a majority of  usage away from the few “on-peak” hours when our customers use energy the most.

Both plans feature low off-peak power supply prices and even lower rates during “super off-peak” hours – 10 p.m. to 5 a.m. – so that EV owners can charge their vehicles overnight.

  • Time-of-Use Electric Vehicle plan: offers low energy charges most of the day, on weekends and on major holidays, but higher rates during on-peak hours when customers typically use the most energy.
  • Demand Time-of-Use Electric Vehicle plan: combines lower off-peak rates with on-peak rates and a “demand” charge based on your highest individual hour of usage during on-peak periods.

EVs can lower your transportation costs through reduced fuel and vehicle maintenance expenses while also reducing emissions. Charging your EV overnight will help you save even more while also supporting reliable, affordable electric service for everyone through more efficient use of the electric grid.

EV owners could pay significantly less to charge their EVs on one of the new pricing plans. The average monthly cost to charge an EV on TEP’s new Demand Time-of-Use EV plan is about $18, compared to about $34 on TEP’s Residential Basic plan.

Electric Vehicle Charging Comparison

TEP Residential Pricing Plan Approximate Monthly Vehicle-charging Costs (Low-use to High-use Customers)
Demand Time-of-Use EV $17-$19
Time-of-Use EV $28-$32
Time-of-Use $30-$34
Basic $33-$36

The two new pricing plans expand TEP’s incentives for EV users. TEP residential customers can claim a rebate covering up to 75 percent of the cost of installing a home electric vehicle charger (EVC). The rebate is up to $500 for a qualified two-way communicating EVC or up to $250 for a one-way, non-communicating EVC.

In the near future, TEP also plans to offer incentives for homebuilders who pre-install electric wiring to accommodate qualifying EV charging stations.

To sign up for new EV rates, TEP customers will need to provide a copy of their state registration document for a highway-approved battery electric vehicle or plug-in hybrid electric vehicle and home charging equipment. Additional eligibility requirements apply.

Customers can sign up for the new EV rates by calling our Customer Care team at 520-623-7711.
