Residential Conservation Services (RCS)

Regulations & Statutes governing residential energy efficiency programs in Massachusetts

The Residential Conservation Services (“RCS”) statute (M.G.L. c.164 App.§§2-1 to 2-10), signed into law in 1980, created the framework for residential in-home energy efficiency services around which Massachusetts’ nation-leading programs are built. On April 7th, 2017, amendments to the RCS regulation (225 CMR 4.00) were promulgated, completing a multi-year process undertaken by DOER to update the regulation.

RCS Regulations & Statutes

The goals of the update are to better integrate efficiency and renewable energy opportunities and provide more consistent, comprehensive services to Massachusetts residents regardless of the fuel being used to heat a building or the number of units in a building. Furthermore, the revised regulation seeks to ensure that contractors provide quality work to customers and have a transparent path into and out of the RCS program. The revision also streamlined the regulation, clarifying the responsibilities of both DOER and regulated parties. 

The RCS statute requires DOER to create a State Plan to further implement the RCS program. Currently, the State Plan is set forth in the form of a Guideline that clarifies the RCS regulation. The DOER intends to begin the process to update this Guideline in 2017 and will be seeking public comment on the Guideline.  DOER will provide more information as it becomes available.
