Tucson Electric Power Company

TEP no longer offers an EV-specific residential rate. Its Residential Super Off-Peak Electric Vehicle plan, which had a 10 p.m. to 5 a.m. super off-peak window, was retired in March 2024. EV owners now use TEP's standard residential Time-of-Use plan, which prices weekday late-afternoon and early-evening hours highest and makes overnight, weekend, and holiday hours cheaper. Charging in those off-peak hours costs less than charging during the weekday on-peak window. Check TEP's current Time-of-Use schedule for the exact on-peak hours before enrolling.

The residential charger rebate is tied to the rate. To claim 75 percent of a networked Level 2 charger's cost, up to $300, a customer must be on the Time-of-Use plan, and up to two rebates are allowed per home. TEP also pays $100 to pre-wire a new home for EV charging outside jurisdictions with an EV charging ordinance. The commercial Smart EV Charging Program is separate and larger, paying per-port rebates for workplaces, multifamily sites, and DC fast chargers rather than crediting a residential bill.

TEP is one of three large Arizona electric providers and should not be confused with Arizona Public Service or Salt River Project, which run different programs. As an investor-owned utility, TEP's rates and EV programs are set through Arizona Corporation Commission dockets, so amounts and plan availability can change with rate cases. The commercial Smart EV Charging Program has a defined funding window, with applications closing May 31, 2026, and rebates issued no later than December 2026.
