Is the TOU or EV plan worth it?

If you drive 700+ miles/month and can charge overnight or on weekends, Tucson Electric Power's time-varying rate often saves money — peak rates can run 3.0× off-peak. If most of your usage happens during peak hours (often late afternoon), TOU may cost more than a flat plan.

Scenario	Est. annual cost

Charge off-peak ($0.08/kWh)	$251/yr
Estimated savings (off-peak vs peak)	$503/yr

Utility notes

Basic plan is tiered (up to 500 kWh cheaper, 1000+ kWh most expensive). Plain TOU plan has no demand charges — good for EV owners who can shift charging overnight. Demand TOU plan also available but includes demand charges ($11.60-16.85/kW). Rate case pending: ~13% increase requested, effective ~Sept 2026 if approved by ACC. Monsoon season (July-Sept) creates storm preparedness opportunity.
