Westford Power Options Program (POP)

Westford Power Options Program (Westford POP) is the new name of Westford’s electricity aggregation program.

Westford POP is a town-run program that leverages the buying power of Westford’s residents and businesses to provide electricity options, stable long term rates and more renewable electricity. The only change is the source and cost of electricity supply, chosen by the town of Westford through a competitive bidding process.

The program began in 2016, when the and has been renewed for another 35 months, starting January 2021.

Electricity Options

Starting on the electricity meter read date in January 2021, your electricity will be supplied by Constellation.

No action is needed to remain in the program on the default option.

In addition to the default option which contains 10% more renewable electricity than required by state law, the program also offers two options with 50% and 100% more renewable electricity. You can sign up for either option, choose a basic option without extra renewable electrify, return to the default or leave the program at any time. You can also check the sample bill for an illustration of a simple way to tell if you a part of Westford POP.

Disclaimer: A goal of the CEA program is to produce savings for customers, but savings cannot be guaranteed compared to the utility’s basic service rate which changes every six months for residential and commercial customers, and every three months for Industrial customers. The aggregation program seeks to provide price stability and average savings over the full term of the program, but because future basic service rates are not known, there is no guarantee of savings.

Enroll or change option

If you’re already participating in the Power Options Program, you can also use this form to sign up for additional renewable electricity with Pop Silver 50% or Pop Gold 100%.

Opting Up to POP Gold 100% is a
powerful way to combat climate change!

If you are not participating in the POP program, you can use this online form to enroll in one of the POP options. If enrolling, once service has begun, your choice will be reflected on your following month’s electricity bill for the previous month’s service. Please note that based on your meter read date, it may take up to two billing cycles to get enrolled.

Be sure to use the name and address associated with the account!

Located in the Enrollment Information section in the left hand column of your National Grid bill (usually the first four letters of the last name associated with the residential account). The code is unlabeled but is listed in capital letters after the Cycle.

Clean Electricity in the Westford POP program

Westford is committed to supporting the growth of new, local renewable energy sources in our region. The State of Massachusetts has progressive policies that require the utilities to supply more renewable energy over time, however, the pace of the change needs to be faster to mitigate the effects of climate change. Westford Power Options Program (POP) is leveraging the buying power of our community to bring more clean electricity to our residents and businesses.

Westford’s standard product, POP Green, has 10% extra renewable energy included, above and beyond the state requirements. 

Participating in POP Green 10% is only the first step in fighting climate change. Westford also offers optional products with 50% and 100% renewable energy to let you take an even bigger step in the fight against climate change. 

Opt Up to 100% Clean Electricity!

Buying from New England, Buying Clean

In the Westford Power Options Program program, all extra renewable energy qualifies for Massachusetts Class I (MA Class I) designation. It also meets additional standards to provide Westford with the cleanest options and the most local impact: all renewable electricity is sourced only from New England and includes only wind, solar, small -scale hydro and digester gas plants.

Green Energy Consumers Alliance, the MA-based non-profit that sources for all of Westford’s extra renewable energy, helps bring new renewable projects to New England through long-term contracts and strategic targeted project support. The renewable energy sources that Green Energy Consumers can provide to Westford POP are shown below.

Only New England Sources

MA Class I-designated renewable energy can come from New England or adjacent parts of Canada and New York. It is one of the most stringently green standards in the country, but Westford POP is even better: we exclusively source our extra renewable energy from within New England. We’re helping to keep our energy impact local, supporting New England’s clean energy economy.

Only Zero-Emission or Methane-Destroying Sources

The Westford POP’s extra renewable energy only comes from zero emission sources, such as solar, wind, low-impact hydro1, or sources that destroy the potent greenhouse gas methane, such as anaerobic digestion2. Although traditional biomass, such as wood-fired generation, is eligible as MA Class I, the Westford Power Options Program does not include and does not plan to include any for its extra renewable energy. 

Helping to Build Clean Energy

Massachusetts has a requirement for every electricity supplier to include a minimum amount of MA Class I renewable energy, and that amount increases each year. If you don’t meet the requirements, you pay a penalty. This policy, known as the Renewable Portfolio Standard, provides growing demand for renewable energy, which incentivizes new renewables to be built. By purchasing a significant quantity of extra MA Class I renewable energy, Westford Power Options Program is increasing demand, incentivizing developers to build even more renewable energy projects. 

How big is our impact? In 2021 Westford Power Options Program customers are expected to purchase an extra 5,500 MWh of MA Class I renewable energy, above and beyond State requirements. These voluntary purchases are equivalent to the output of 1.5 typical New England onshore wind turbines. As more residents and businesses opt up to our POP Silver 50% and POP Gold 100%, we can increase the impact even more!

We are excited that many other cities and towns are joining with Westford to implement the same type of program and amplify our impact. In fact, recent estimates suggest that fully 10% of renewable energy purchased in the MA Class I REC market will soon be voluntarily purchased by municipal aggregations going above and beyond state requirements, like Westford Power Options Program. 


1 Hydro projects that do not exceed 30 MW built after 1997 or have capacity additions or efficiency improvements made after 1997 (MA Class I eligible), and Low Impact Hydro Institute (LIHI) certified.

2 Methane has a global warming potential (GWP) 28-36 times greater than CO2 over a 100 year period. Combustion destroys methane and releases some CO2, resulting in a net reduction in GWP.
