Aggregation Background

Municipal electricity aggregation is a mechanism by which a city or town can bundle the electricity supply needs of residents and businesses in their community and procure the electricity in bulk, typically for a multi-year term.

Municipal aggregation is allowed under Massachusetts General Laws Chapter 164 Section 134. More than 140 cities and towns in Massachusetts already have active electricity aggregation programs, and other nearby communities are pursuing similar programs. 

By default, customers receive “Basic Service” electricity supply from Eversource. Under a municipal aggregation program, like eMPower Millis, all customers receiving Basic Service are automatically transitioned to the aggregation’s standard option. However, before the aggregation begins, all customers must be given the chance to stay with Basic Service, known as “opting-out”. After customers are enrolled, they can still opt out of the aggregation at any time without penalty.

eMPower Millis Implementation

In 2016, the Town Meeting authorized the creation of a community electricity aggregation program in Millis. The Town then selected consultant Good Energy, L.P. to assist with all aspects of program implementation. The Town developed a draft aggregation plan and subsequently solicited public input. As required by law, the plan was reviewed with the MA Department of Energy Resources and then sent to the Department of Public Utilities (DPU) for review.

Read the Millis Aggregation Plan (approved November 2018)

Millis conducted a bid for electricity supply and secured a supply contract to start in January 2021. Prior to the start of the program, Millis conducted an education and outreach program to notify eligible residents and businesses about the program and their right to opt out of the program before it started.
