How the two plans work

RS: Residential Service

  • One price per kWh at every hour, all year: 11.7¢.
  • Shifting use to other hours changes nothing on this plan; using less is the only lever.
  • Fixed charge: $14.54 a month.

RTOD-Energy: Residential Time-of-Day Energy

  • Peak 2 pm–6 pm on July weekdays; 4 of 24 hours carry the top price of 19.4¢.
  • The cheapest July weekday hour costs 9.5¢, so moving 1 kWh out of the top hours saves 9.9¢.
  • January weekdays range from 9.5¢ to 19.4¢.
  • Weekends follow a different schedule from weekdays.
  • Fixed charge: $14.54 a month.
