    Distributed Generation and Interconnection in Massachusetts

    In the Green Communities Act of 2008, the Commonwealth of Massachusetts set a goal to have clean energy generation serve 20% of customer load by 2020. Much of that power will come from on-site, distributed generation (DG), such as combined heat and power and renewable sources like solar photovoltaics (PV) and wind. This website provides information and resources regarding two key issues affecting DG: interconnection and net metering.

    Interconnection

    Interconnection is the process of connecting a distributed generation system to the electric grid. Prior to interconnecting, distributed generation system owners seeking to operate their systems in parallel with grid power must have a signed interconnection authorization from the local utility. The interconnection process was adopted by Order of the Massachusetts Department of Public Utilities (DPU) through its regulation of the utilities and their complying tariffs. See DOER's new interactive charts on electric utility reporting.

    Net Metering

    While distributed generation systems provide power to their host customers first, they often export power to the electric grid as well.  Net metering is a mechanism that allows distributed generation system owners to be compensated for that exported power. Net metering in its current form is the result of Legislation and was implemented under the authority of the Massachusetts Department of Public Utilities (DPU) through regulations and complying utility tariffs. 
      Grid Modernization

    Grid Modernization is currently being investigated under the authority of the Massachusetts Department of Public Utilities (DPU) through a recent Notice of Investigation.  One primary objective of the investigation is to find in which a modern grid can further integrate distributed energy resources. DOER plans to actively engage with Grid Mod stakeholders in future stages of this proceeding.
