The Millbury Solar Farm

Sign up to participate in Millbury's community solar program


Located at 442 Greenwood street, Millbury is clocking in at 1.4 MW. The solar farm in the photo above is currently open for customers in National Grid WCMA load zone who can capitalize on a portion of the power produced by the array!

Half of the project will be filled by a Massachusetts-based college, and the remaining openings will be available to members of the community who are customers of National Grid. Continue reading below for details explaining how community solar works, and how to apply!


1400 kW










December 2018


National Grid WCMA customers must meet the following requirements to be eligible:

  • Provide a scanned copy or picture of your National Grid utility bill
  • Have a credit score of 680+


You will have the opportunity to participate in the community solar program for the full project lifetime. You may cancel at any time with 6 months notice1.



You will save every month you participate in the community solar project and receive credits at a discount to your utility bill2.


Developers like Green Street build large solar "farms" capable of generating power for hundreds of homes

The energy produced by the solar farm is sent to the electrical grid

Subscribers will see a monetary credit on their utility bill each month related to their participation 




1. You may opt out of the program without penalty fees if 6 months notice is given to [email protected], or if you find a replacement for your slot. If less than 6 months notice is given or a replacement it not found, you will be responsible for paying up to 6 months cost of participation.

2. If you purchase your basic service from a retail supplier, you must be billed for that supply on your National Grid bill in order to receive the community solar credit on your utility bill. We will check your bill for you.


What are the benefits?
By opting into community solar, you’re supporting the use of green energy which reduces CO2 emissions, having an overall positive impact on the environment. Plus, program participants save money each year.

How much will I save?
You will save up to 10% on your utility bill.

How much of the project will I be allocated?
We will look at your historic utility bills and size your share of the community solar project so that over the course of the year you will receive credits that approximately match your overall annual energy usage.

Will I have two bills now? 
Once the community solar project begins generating energy, you will receive a discounted bill from National Grid each month and then pay GSPP for your share of the project. Between these two bills, you will always be paying less.

Where do I see the credit?
You will see a credit on your utility bill each month. Although your monthly utility bill credit will fluctuate depending on how much power the system produces (more in the summer, less in the winter), you will always pay a discount to this credit value. We will reconcile your bills and your solar credits annually to make sure that you have received full credit for what you have paid in your contract.

Do I own panels?
The beauty of community solar is that you get the financial benefits of solar without any of the risk or responsibility of ownership. GSPP owns the panels and will maintain them for the full term of your participation.

How does my home use the solar power / how does the solar power come to my home?
Because the community solar project isn't located on your roof, the actual energy doesn't go directly to your home. The energy that's generated from the project goes into the local grid and you receive credits on your utility bill for the power generated.

What does it cost to participate?
There is no enrollment fee, you simply pay for the credits you will be receiving, at a discount.

What are the qualifications / requirements for participating?

  1. You must be a current National Grid customer in the same load zone as Millbury (we will know after looking at your utility bill)
  2. Your credit score must be 680+*

*GSPP needs your authorization to perform a soft credit check

How many people can participate 
This project will be limited to the first 300 customers who sign up. When the project is full, we will create a waiting list so that you will be placed in the program if spaces become available. So don't wait, sign up now!  

How do I sign up?
Sign up by clicking on the form above. Program participation is operating on a first come first served basis. Once the program shares are filled, we will begin adding names to a waiting list.

When does the program start?
The project is expected to begin generating electricity in December of 2018.

If I enroll, how long am I committed to the program?
You are committed to the project for as long as you'd like to save money on your utility bill and participate in community solar. You can cancel at any time by providing us appropriate advanced notice. 

What if I move?
If you move outside of the National Grid load zone during your period of participation, unfortunately you will no longer be eligible to participate and we will have to opt you out of the program. If you move to a new home within National Grid, you can still participate in the project. Simply send us an email and we will make sure your address and utility account information is updated. Email [email protected] to leave the program or transfer.

If I change my mind about participating, can I leave the program?
If you decide you would like to leave the program or if you move outside of the National Grid load zone -- no problem, you only need to give 6 months notice. If you find a participant to replace you, you only need to give 90 days notice plus the name, telephone number, and email address of your replacement. 


To participate in the program, complete the sign-up form below (there's no cost to sign-up). You will be asked to upload a copy of your National Grid bill and authorize us to check your credit score.


Subscribers who participate in community solar pay for the credits allotted to them at a discount
