How the two plans work

R: Residential Service

  • Shifting use to other hours changes nothing on this plan; using less is the only lever.
  • Fixed charge: $14.72 a month.

R-TOU-ND: Residential Time of Use Non-Demand

  • Peak 10 am–9 pm on July weekdays; 11 of 24 hours carry the top price of 31.0¢.
  • The cheapest July weekday hour costs 10.9¢, so moving 1 kWh out of the top hours saves 20.1¢.
  • January weekdays range from 11.7¢ to 30.4¢.
  • Weekends differ: off-peak all day.
  • Fixed charge: $19.86 a month.
