NH Electric Vehicle Time-of-Use Rate

NH Residential & Commercial Electric Vehicle (EV) Time-of-Use Rate:

New Hampshire electric customers who own an electric vehicle may be able to save money on charging by signing up for Unitil's EV Time-of-Use rate. An additional meter is needed to measure the charging of electric vehicles and will be installed by Unitil. You would be responsible for hiring an electrician to install an additional meter socket/location to house the Time-of-Use meter.

New Hampshire residents may opt into either or both Whole House and Electric Vehicle Time-of-Use Rates.

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.

Commonly Asked Questions About EV Time-of-Use

We do not recommend ever charging your EV during on-peak hours. The on-peak rate is higher than the standard rate and will make it very hard to build overall savings if charging is not consistently done during off-peak hours. We suggest finding an alternative way to charge your vehicle if you find yourself needing to charge during on-peak hours.

Mid-peak hours are roughly the same prices as the standard rate so while charging during these times isn't ideal, it is more of a wash in the savings department.

What is a Level 2 charger?

A Level 2 charger is a special unit installed at a home or business that requires a 240 volt plug (a standard clothes dryer plug) and charges electric vehicles at a faster rate. Level 1 charging is when you charge an EV from a regular, 110 volt outlet; this method can take twice the time, or more, to charge your EV. Commercial locations have DC Fast Charge (Level 3).

Do I need a level 2 charger to opt-in to the Electric Vehicle Time-of-Use Rate?

No, Unitil does not currently require any special charging equipment to apply for the EV Time-of-Use rate. The rate does always require the installation of a dedicated utility meter. Unitil does encourage you to research the charging time of your EV if you do not have a Level 2 charger, as charging from a standard outlet in your home (Level 1) may take many more hours, which may make charging only on non-peak hours impossible.
