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 Tiers

Time-of-Use rates are broken into three tiers and time frames. Each time frame has a different rate. The graph below is a general overview of how these rates work and how pricing compares to the standard rate.

Is Time-of-Use a good fit for you?

 

Depending on your lifestyle, Time-of-Use could offer great savings. Time-of-Use consumers should attempt to use most of their electricity during off-peak times to see the most savings and avoid on-peak usage as much as possible.

If shifting most of your electricity usage away from 3 - 8 pm (Mon - Fri) isn't possible, remaining on the standard rate is your best option.
