How does my utility rate impact my utility bill savings?

Your utility rate determines how much you pay for electricity at different times of day, and that directly affects how much you can save with smart charging or bidirectional charging.

Here’s how it works:

• If your rate is Time-of-Use (TOU):
  Electricity is cheaper during off-peak hours and more expensive during peak hours.
  → You save money by charging when rates are low and powering your home or exporting when rates are high.
• If your rate is a Dynamic Rate:
  Prices change in near real time based on actual grid conditions.
  → You maximize savings by letting Bidirectional Energy use your EV to automatically respond to high and low price periods, adjusting charging and discharging minute-by-minute.
• If your rate is flat:
  Prices stay the same all day.
  → Savings come from export earnings or grid program participation only, rather than shifting your home’s usage patterns.

Your utility rate influences:

• When it’s cheapest to charge your EV
• When it’s most valuable to power your home from your EV battery

Because your EV battery is flexible, the more your rate rewards shifting energy use, the more savings the system can achieve for you.
