Interconnection puts renewable energy generation in your hands.
Customers who generate more electricity than they need can push that electricity back out through their meters as a surplus.
Interested in installing a renewable energy system on your property? The interconnection process doesn’t have to be complicated. In six easy steps, you can complete, submit and finalize your application to enjoy the benefits of renewable energy generation.
To make the interconnection process easier, Unitil has an online application system that will determine which application is right for you. Familiarize yourself with the information on this page before beginning the application process.
It is very important you do not energize your system until you receive the approval to energize/interconnect your system. If you energize your system prior to Unitil changing your meter, your meter will register any surplus generation as load and you will be charged.
If you’d like to send your application in writing, please mail it to:
