eMPower Millis

eMPower Millis is a program offered by the town of Millis to provide new electricity supply options and more renewable energy to Millis residents and businesses. The Program is a town-vetted alternative to Eversource’s default supply and other third party electricity suppliers.

Program Products

eMPower MIllis has a default option, called Millis Regular. Participants in the program receive Millis Regular unless they affirmatively choose one of the other electricity options

In addition to the standard electricity supply product, the Program also offers an option with 100% total energy from renewable energy certificates. You can sign up for either option, 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 the CEA program.

Please note: Prices for all products in the program include a $0.001/kWh administration fee. Program prices apply only to the electricity supply portion of your electric bill. Delivery charges on your electric bill are not affected by the program.

For Commercial and Industrial Eversource Basic Service Rates please check out the Eversource supply rates page.

All of the additional RECs included in the program are designated as Massachusetts Class I. RECs are the accepted legal instrument used to track renewable energy generation and to substantiate claims of renewable energy use. Learn more about the RECs that are included on the Renewable Energy page.

Goals of the eMPower Millis program

Support Renewable Energy Resources

eMPower Millis’s standard and optional products include more Renewable Energy Certificates (MA Class I), than required by the Commonwealth. This means you can support the growth of renewable energy generation in our region.

Competitive, Stable Price

Using strategic purchasing, combined with the bulk purchasing power of thousands of households and businesses in the program, eMPower Millis provides competitive, stable rates. Please note, savings compared to Eversource Basic Service cannot be guaranteed because Basic Service prices change every six months for residential and commercial customers and every three months for industrial customers.

Increased Choice and
Easy Participation

The program offers 3 different options for electricity supply so that everyone in Millis can find an option that fits their budget and climate goals.

Participants in eMPower Millis may leave the program at any time without penalty.

Solar Electricity Consumers will continue to receive their net metering credits while participating in the program.

Budget Plan or Eligible Low-Income delivery rate consumers will continue to receive those benefits from the utility.

How it works

eMPower Millis does not replace Eversource as our electric utility: they continue to deliver electricity, repair outages and manage all billing.  The program offers alternatives for the Supply portion of your bill.  See the Understanding Your Bill section on the Eversource website to see the difference between Supply and Delivery sections.

Most residents and businesses in Millis already participate in the eMPower Millis program. Check your electricity bill to see if you’re one of them: the Supplier should be listed as Constellation – Millis. If Eversource is still listed as your supplier, you may complete the enrollment form to sign up for eMPower Millis. If a different supplier is listed, contact that supplier to check for penalties or termination fees that they may charge before you join the eMPower Millis program.

Participation in the eMPower Millis program is voluntary: you can leave the program at any time without fee or penalty.

The program will periodically send Customer Notification letters to new or newly eligible electricity customers, which includes the program details, information about product prices, and renewable energy certificates. Customers who receive this letter and do not choose to opt out will be automatically enrolled. To enroll sooner, use our online forms.
