About Municipal Aggregation

Residents in Auburn and communities across the State are faced with escalating electric costs which increase household expenses and put a burden on homeowners, families, low-income populations and seniors. Commercial customers are challenged by high electricity costs which are consistently highlighted as a barrier to economic growth in central Massachusetts. Residents and businesses in Auburn and other communities in the Commonwealth have felt the impact of skyrocketing electricity supply costs over the past two winters.

The Town of Auburn’s Municipal Aggregation Plan is designed to address this uncertainty in electricity costs by combining the purchasing power of its residential and commercial customers and by competitively bidding that load on the open market. By combining this purchasing power, the Community Choice Municipal Aggregation Plan enables customers to achieve stability in their electric rates and control their electric costs.


The Town of Auburn has been working with its municipal energy consultant, Colonial Power Group, Inc. since April of 2015 when they were chosen by the Board of Selectmen after a competitive process. The Wind Turbine and Alternative Energy Committee had held interviews for 3 municipal aggregation consultant candidates over the course of 2014 before recommending Colonial Power Group to the Town Manager. The Town Manager concurred with the recommendation of the Committee and recommended Colonial Power to the Selectmen.

In May, the Town submitted its Community Choice Municipal Aggregation Plan to the state for review. Following approval by the Department of Energy Resources (DOER) this summer and a public hearing held by the Massachusetts Department of Public Utilities (DPU) in August, DPU gave final approval to Auburn’s Community Choice Municipal Aggregation Plan on September 17th, 2015.


The Town would like to thank State Senator Michael Moore and State Representative Paul Frost for their support and recommendations of this plan to the DPU. The Town also thanks the following for their efforts with this energy initiative:

  • Auburn Board of Selectmen
  • Colonial Power Group
  • Town Counsel
  • Town’s Planning Division
  • Wind Turbine and Alternative Energy Committee
