What is Time-of-Use? 

Historically, Unitil has offered the standard rate which charges one price for every kWh you use no matter the time of day you use it. This option is still available to electric residents and business customers throughout all our service territories. 

Time-of-Use (TOU) rates have different electricity prices based on the time of day electricity is used. Customers can manage their bills by shifting tasks that require electricity to off-peak hours when electricity costs are the lowest.

time of use graph explaining mid-peak hours are 6am to 3pm, costing about the same as standard rate. On-peak hours are 3pm to 8pm, costing about 3x the standard rate. Off-peak hours are 8pm to 6am, costing less than the standard rate.

All holiday and weekend hours are billed at the off-peak rates no matter the time of day.
