On February 10, 2026, NRG filed a petition for adoption of rules to support community choice aggregation with the Maine Public Utilities Commission (PUC) for the adoption of rules supporting community choice aggregation as authorized by 35-A M.R.S. §§ 3201 and 3202.

In particular, NRG petition explicitly asks the Commission to adopt specific guidelines for Community Choice Aggregation (CCA) within Chapter 305 of the Commission’s rules.

In addition, NRG’s petition includes a CCA Redline of Chapter 305 detailing suggested changes necessary to incorporate a CCA program in Maine.

The petition contends that [“w]hile § 3202 creates the opportunity for “consumers of electricity [to] aggregate their purchased of generation service in any manner they choose,” it also allows a “public entity” to serve as an aggregator on behalf of its consumers, but the Commission has never initiated a rulemaking to develop more guidelines for public entity-aggregated supply, also known as Community Choice Aggregation (“CCA”).3 The Commission’s existing Chapter 305 rules already include definitions which indicate that the original implementation of Chapter 305 intended to include municipal aggregation programs such as CCA, sharing definitions for “Entity”4 and “Aggregator”5 with § 3202, which support a municipality or other governmental entity to act on behalf of consumers. However, Chapter 305 does not set out clear guidelines for opt-out CCA, as was envisioned by §§ 3201 and 3202 and is the most effective way to provide the best pricing and product offers within these communities. NRG hereby petitions the Commission to adopt specific guidelines for CCA within Chapter 305 of the Commission’s rules, as was envisioned by the Legislature in 1997.”

“Given the lack of clarity as to organizational and program requirements of a municipal or public entity aggregated program, the Commission should amend existing Chapter 305 to include specific guidelines for CCA programs.”
