How Duke Energy Indiana’s plans work
RS (Residential Service). In July the first 300 kWh a month cost 19.3¢ each; then 14.3¢ above 300 kWh a month, then 13.0¢ 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 (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 22.1¢. The cheapest July weekday hour costs 9.3¢, so moving 1 kWh out of the top hours saves 12.8¢. January weekdays range from 9.3¢ to 22.1¢. Summer pricing applies Mar–Oct; winter pricing Nov–Feb. Fixed charge: $13.70 a month.
