Submit an Online Application

We have re-designed our interconnection application portal to streamline the application process. With our new form, you can create an account to keep track of all of your application submissions.

We will ask you a few preliminary questions to determine which application process you will need to complete. Upon completion, your application will be submitted for review by a Unitil representative.


** Attention MA Applicants **

As a result of the high interest in solar interconnection and renewable energy, we are at a point of saturation in some portions of our service territory. On a day of optimal generation, the potential exists for the renewable generating facilities to meet the energy needs of all the homes around them and also have excess energy feed backwards into the nearest supply substation. Any additional generation in the area may lead to safety issues at the nearby substation without specific modifications.

Unitil is required to follow the tariffs which govern interconnections in Massachusetts, and the tariff states that all system modifications resulting from solar saturation have to be paid for by the interconnecting customer or customers that trigger the need of system modification. However, the cost of these modifications are often well above the initial planned costs for these installations, which in turn leads to project delays.

As a Company, we recognize the cost of this particular modification is high and that the tariff as written presents real obstacles for some small interconnection projects, especially at the residential level. While we are required to follow these tariffs as currently written, we have raised the issue with the Massachusetts Department of Public Utilities (DPU), the state regulatory body which governs such matters. The DPU has agreed to open up a review of this tariff and explore alternatives. We are committed to continuing to work with the Department of Public Utilities to find a more equitable solution for all of our customers, but no change is expected in the tariff until 2020 at the earliest.
