How the two plans work
RS: Residential Service
- In July the first 300 kWh a month cost 19.0¢ each; then 13.9¢ above 300 kWh a month, then 12.6¢ above 1,000 kWh a month.
- 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: $13.70 a month.
RS TOU (Tariff No. 6.5): Residential Time-of-Use
- Mid-peak 12 am–1 am, Mid-peak 5 am–6 pm, Peak 6 pm–10 pm, Mid-peak 10 pm–12 am on July weekdays; 4 of 24 hours carry the top price of 21.7¢.
- The cheapest July weekday hour costs 8.9¢, so moving 1 kWh out of the top hours saves 12.8¢.
- January weekdays range from 8.9¢ to 21.7¢.
- Summer pricing applies Mar–Oct; winter pricing Nov–Feb.
- Fixed charge: $13.70 a month.
