Municipal Aggregation Manual & Best Practices Guide

DOER's Municipal Aggregation Manual and Best Practices Guide provides municipalities with a resource to assist in the formation and management of a municipal aggregation.

August 2024 Updated Municipal Aggregation Manual

DOER released an updated version of its Municipal Aggregation Manual on August 30, 2024.

The Manual was developed in response to municipalities’ increased interest in establishing municipal aggregations. It seeks to provide information that supports the effective and efficient formation of municipal aggregations, equips municipalities to advocate for municipal interests when forming a municipal aggregation, and improves collaboration with DOER on municipal aggregation formation.

On August 18, 2023, the Massachusetts Department of Public Utilities (DPU) opened an investigation to establish municipal aggregation guidelines. DOER and other stakeholders participated in this investigation, which resulted in a new set of DPU Guidelines released in July 2024.

Following the finalization of these new Guidelines, DOER released an updated version of its Municipal Aggregation Manual and Best Practices Guide in August 2024. As part of the new Guidelines, DOER also developed a set of best practices for advancing clean energy with aggregation.

Municipalities are required to consult with DOER as they develop municipal aggregation plans. Municipalities that wish to schedule a consultation with DOER should contact their Green Communities Regional Coordinator.
