Distributed Generation Working Group

On January 23, 2012, the Massachusetts Department of Public Utilities (DPU) established a Distributed Generation (DG) Working Group to develop recommendations for changes to the Uniform Standards for Interconnection Standards for Distributed Generation. The Working Group, which included representatives of DOER, the Massachusetts Clean Energy Center, the distribution utilities, distributed generators, and customers, filed its final report (9/14/12). 

On March 13, 2013, the DPU issued an Order (
DPU 11-75-E) approving the recommendations in the DG Working Group Report filed in August 2011 and directed the utilities to file compliance tariffs within 30 days. On May 2, 2013 the DPU stamp approved the utility compliance tariffs. As a result, the new interconnection tariffs proposed by the DGWG and the associated timelines and policies are now in effect.


DOER is hosting this page to make available additional materials associated with the Distributed Generation Working Group. DOER will continue to use this page to document the implementation of the recommendations of the Distributed Generation Working Group.
