Schedule R or TOU-R: common questions

Is Schedule R or TOU-R cheaper?

For a typical Hawaii home using 514 kWh a month, TOU-R is cheaper by about $133 a year ($257 against $268 a month). TOU-R is cheaper or about the same at every level of use from 200 to 2,500 kWh a month, with the same daily pattern of use. Adding an EV driven 1,000 miles a month and charged at each plan’s cheapest hour, TOU-R gives the lower total ($325 against $405 a month).

What is the difference between Schedule R and TOU-R?

Schedule R is tiered: the price per kWh rises with monthly use, with a fixed charge of $15.30 a month. TOU-R is time-of-use (summer weekdays: Mid-peak 12 am–9 am, Peak 5 pm–9 pm, Mid-peak 9 pm–12 am; lowest price 9 am–5 pm), with a fixed charge of $21.13 a month.

How the two plans work

Schedule R: Residential Service

  • In July the first 350 kWh a month cost 48.6¢ each; then 50.0¢ above 350 kWh a month, then 52.3¢ above 1,200 kWh a month.
  • An average Hawaii home (546 kWh in July) goes past the first tier, so extra load such as an EV is priced higher.
  • Fixed charge: $15.30 a month.
  • Minimum bill: $30.22 a month.

TOU-R: Residential Time-of-Use

  • Mid-peak 12 am–9 am, Peak 5 pm–9 pm, Mid-peak 9 pm–12 am on July weekdays; 4 of 24 hours carry the top price of 74.4¢.
  • The cheapest July weekday hour costs 24.8¢, so moving 1 kWh out of the top hours saves 49.6¢.
  • January weekdays range from 24.8¢ to 74.4¢.
  • Fixed charge: $21.13 a month.
  • Minimum bill: $30.22 a month.
