Notice of Filing and Public Hearings

On April 5, 2019 the Department of Energy Resources (DOER), acting under statutory authority of Sections 11F and 11F1/2 of Chapter 25A of the General Laws, and in conformance with Chapter 30A of the General Laws, filed draft regulations to amend portions of  225 CMR 14--Renewable Energy Portfolio Standard – Class I (“RPS Class I”) and 225 CMR 15--Renewable Energy Portfolio Standard – Class II (“RPS Class II”). These regulations require all retail electricity suppliers selling electricity to end-use customers in the Commonwealth to obtain specific minimum percentages of their electricity supply from renewable energy generation sources.  The proposed amendments revise the RPS Class I and RPS Class II regulations to address policy related changes, including changes required in order to implement Section 12 of Chapter 227 of the Acts of 2018, now codified at M.G.L. c. 25A, § 11F.

The following public hearings were conducted to receive verbal and written comments on the proposed RPS Class I and II regulations.
