  • An average Indiana home (1,225 kWh in July) goes past the first tier, so extra load such as an EV is priced higher.
  • Fixed charge: $15.00 a month.

RS-TOD2: Residential Service Time-of-Day 2

  • Peak 2 pm–6 pm on July weekdays; 4 of 24 hours carry the top price of 27.7¢.

  • In January every hour costs the same (13.7¢).
  • Summer pricing applies May–Sep; winter pricing Oct–Apr.
  • Fixed charge: $15.00 a month.
