Key Findings

Misleading “off-peak” Savings

  • • Some plans show less than 20% savings during off-peak hours
  • • The fixed Base Services Charge reduces the percentage savings on the full bill
  • • Tiered DR plans can still be competitive depending on baseline allowance
  • • Actual savings depend on how much usage can move out of 4pm-9pm

Super Off-Peak Value

  • • Super off-peak typically offers the most significant savings
  • • EV-TOU-5 has the largest super off-peak discount among current plans shown
  • • Weekday 12am-6am and 10am-2pm usage can lower energy costs
  • • Automation helps capture the 10am-2pm and overnight windows consistently
