How the two plans work

Rg-1: Residential Service

  • Fixed charge: $16.00 a month.

Rg-2: Residential Time of Day

  • Peak 9 am–9 pm on July weekdays; 12 of 24 hours carry the top price of 25.1¢.
  • The cheapest July weekday hour costs 10.3¢, so moving 1 kWh out of the top hours saves 14.8¢.
  • January weekdays range from 10.3¢ to 22.4¢.
  • Summer pricing applies Jun–Sep; winter pricing Oct–May.
  • Weekends differ: off-peak all day.
  • Fixed charge: $16.00 a month.
