Residential Time-of-Use (TOU) Rate

The day is divided into three pricing periods, each with a different electric rate: 

• Off-Peak Hours: Weekdays from 10 p.m. to 8 a.m., plus all day on weekends and holidays. 
  These hours have the lowest electric rates, making them the best time to charge Electric Vehicles (EVs), run appliances, and use larger household equipment.  

• On-Peak Hours: Weekdays from 8 a.m. to 4 p.m. and 8 p.m. to 10 p.m. 
  Rates during these periods are higher than standard residential rates due to increased electricity demand.  

• Super-Peak Hours: Weekdays from 4 p.m. to 8 p.m. 
  These hours carry the highest electric rates during the summer months (June through September), when electric grid demand is at its greatest. During non-summer months (January through May, October through December), super-peak pricing is the same as the on-peak rate. 

To learn more about the Residential TOU rates associated with off-, on-, and super-peak time periods, and to compare the Residential TOU rate structure to the Residential Service rate, please view the RPU Rate Schedule which can also be found on RPU’s Rates and Fees page. 

Yes. Customers with EVs can save money on their RPU bill by charging their vehicles during off-peak hours. The more miles a customer drives with their EV, the more they could potentially save on their electric bill.  

EV owners and plug-in hybrid electric vehicle (PHEV) owners who enroll in the Residential TOU rate through RPU’s EV rebate program also qualify for a one-time $500 EV Enrollment Rebate. If a customer owns more than one EV or PHEV, any additional qualifying vehicle will receive a $150 rebate. See the Electric Vehicle (EV) Rebate Application for additional details. 

Yes. Customers with solar or other distributed energy resources (DER) who elected to receive the average retail rate for their excess energy are eligible to participate. All energy supplied by the customer to RPU will be credited at the average retail rate listed in Schedule 1.  

Solar customers may benefit from being on the Residential TOU rate because most solar production occurs during on-peak and super-peak time periods when energy costs on the Residential TOU rate are highest. The solar production reduces the amount of energy needed from the grid at these times, potentially lowering solar customers’ energy bills and helping to lower overall grid demand.
