Massachusetts DG and Interconnection Main Page

This website has been created by the Department of Energy Resources in collaboration with the investor-owned electric utilities to focus on the utility interconnection process.*  What's on the website:
  • important information for people installing on-site generation on their premises (standards, upcoming workshops, policies, etc.);
  • an opportunity for utility customer feedback; 
  • registration for interconnection seminars
As directed by the Green Communities Act, it is the state’s goal to have clean energy generation serve 20% of customer load by 2020.  Because much of that energy will be on-site electricity or distributed generation (like solar PV, wind, and combined heat and power), it is now as important as ever to ensure that the interconnection process is as streamlined, uniform, and transparent as possible. 
 
*It's also important to note that customers of utilities must follow interconnection standards when installing distributed generation (DG) for operation in parallel with grid power.

Monthly Project Tracking

The utilities are now voluntarily providing monthly reporting (on the 15th of each month) on all applications following the expedited/standard process (this does not include simplified projects <10 kW).

DOER Files Joint Comments Addressing Interconnection

(1/24/2012) DPU has issued an Order Establishing a Distributed Generation Working Group.  In October 2011, DOER filed Joint Comments with 15 DG Stakeholders recommending the creation of the DG Working Group to improve the process for connecting on-site clean energy projects (such as solar and wind). The filing was in response to DPU's new investigation triggered by the MA DG Interconnection Report filed by DOER on August 18.  See the filings by entering “11-75” at the DPU File Room.
