$129This estimate covers EV charging only. A rate change would apply to eligible supply usage across the household, not only the vehicle.
Estimate only. Uses your state's average residential rate for May 2026, assumes supply is about 55% of your all-in rate, and applies a 30% reduction to the supply portion alone. Delivery charges don't change. Your actual rate depends on your utility, your usage pattern and the plans available where you live.
