How the two plans work

Rate 1: Residential Electric Service (Standard Service supply)

  • One price per kWh at every hour, all year: 23.6¢.
  • Shifting use to other hours changes nothing on this plan; using less is the only lever.
  • Fixed charge: $9.62 a month.

Rate 7: Residential Time-of-Day (Standard Service supply)

  • Peak noon–8 pm on July weekdays; 8 of 24 hours carry the top price of 30.0¢.
  • The cheapest July weekday hour costs 20.8¢, so moving 1 kWh out of the top hours saves 9.2¢.
  • January weekdays range from 20.8¢ to 30.0¢.
  • Weekends differ: off-peak all day.
  • Fixed charge: $9.62 a month.
