I've seen or heard ads claiming Unitil's electric supply rates are increasing and that I should switch to a third party supplier. What's that about?

Third party electric supply companies are allowed to solicit utility customers in our service territories. These solicitations refer to the “supply” rate of your bill, which is only one portion of the overall rate utility customers pay. State regulations require that utilities get fresh bids from energy providers every six months, and this supply rate, which reflects the current market cost to actually make the electricity, changes every six months. We obtain new bids from energy providers bi-annually.

Third party suppliers are allowed to get bids on electricity outside of this cycle. Think of them as like a broker; the rate they offer would replace this specific portion of the overall rate for whatever length of time a customer agrees to. Unitil would still be your electric provider, however, and you would still call us if the power goes out so we can send a crew.

As a company, we support the idea that our customers should explore all options available and that they are free to make a decision on an energy contract that is right for them.

How do I notify Unitil of my life support equipment?

If you or a family member uses electrically-operated life support systems, we encourage you to notify Unitil in advance of any outages by submitting our Physician’s Certification Form found here via email, fax or mail. Once we receive this form, your account will be noted and we will include a notification to you in the event that we anticipate adverse weather or a scheduled outage which may result in a power outage. Click here for more information.

What information do I need to start an account?

You will need to provide us with a handful of information to start service at a new location:

  • The address of the new location
  • The property owner's information (if applicable)
  • The former tenant's name (if applicable)
  • Your name
  • Your social security number
  • Your telephone number at the new location
  • Your mobile or business phone number
  • The date you are requesting service
  • Spouse's name (if applicable)
Where can I find the latest outage and restoration information?


We've centralized all of our outage information in a section on our site called the Outage Center. Here you'll find links to the latest news, public service announcements and outage updates for our customers, as well as general information on seasonal storm preparation, power restoration and being prepared for extended outages. 

We also have dedicated resources and information for municipal contacts in the communities we serve here.

Why does Unitil trim service areas on cycles?

Trimming cycles allow us to control re-growth over a consistent percentage of a service territory and ensure that all areas in a service territory are maintained over a similar period of time.

How does Unitil classify hazard trees?

Hazard, or danger trees, are dead or dying trees or limbs that pose a threat to our electrical facilities.  We make every effort to identify and remove these trees at the earliest possible stage.

How does Unitil handle tree work after storms?


Tree crews are often an integral part of outage restoration during and following a storm. We work with our tree contractors to reserve resources ahead of major storms, and communicate with crews during and after the restoration process to address hazard trees and other compromises to our system.

Tree debris will not be removed during or after storm conditions; this is the responsibility of the owner of the tree. Any debris that is a result of our standard trim cycles is removed or put through a chipper. Pieces not fitting into the chipper are cut into manageable lengths and left for the owner or their designee. Additionally, we do not remove debris after our tree or line crews remove branches or trees during unscheduled outages and other emergencies.

A key reason we don’t take your wood is that it belongs to you! Cut wood has value and can be sold. If your wood is of a high enough quality, you may find someone locally willing to pay to take that wood off your hands.

Will Unitil trim my trees?

If you have requested trimming service from us, we will visit your property for a survey. If the trees in question are encroaching on any power equipment or clearances, or pose a significant threat to the system, we will work with you to remove them.

When and why does Unitil use herbicides?

We plan to use herbicides to maintain tree growth in areas that prove difficult to access with standard equipment (trucks, saws, chippers) and to inhibit the growth of new trees once cutting has taken place. We work closely with local and state offices for the approval, notification and application of any herbicides before we use them. We plan to use herbicides primarily on our transmission system, with potential applications along the distribution system if necessary. 

What is the export feature on my account?

Unitil provides an export feature for our municipal customers to help them better track their energy usage and spending, as well as formulating efficiency, budgeting and planning decisions for the coming months. We’ve worked with the New Hampshire OEP (Office of Energy and Planning), the Massachusetts  DOER (Department of Energy Resources) and a third party provider, Peregrine Energy Group, to refine the available data set for accurate analytics and measurement.   

What time period does my municipal account data export apply to?

The data set displays the previous 24 months of billing history, rolling monthly. The next month’s energy data is available the day after your next scheduled meter read.

Who can I contact if I have questions about my municipal account data?
Please contact Gary Miller at 603-227-4516 for municipal accounts in the Capital service area; Tim Noonis is available at 603-294-5123 for municipal accounts in the Seacoast service area.
Please contact John DiNapoli at 978-353-3259.

If you’re working with a third party provider for energy analytics, we suggest you contact them directly regarding the export.
