The content of this webpage has been temporarily removed while we prepare to post new interconnection process information related to the new Interconnection Tariff.
The Massachusetts Department of Public Utilities (MDPU) recently approved a new version of National Grid’s Standards for Interconnecting Distributed Generation (also known as the “Interconnection Tariff”) under MDPU order 1219 (cancelling MDPU order 1176). This new tariff is now available for download on the National Grid website at: http://www.nationalgridus.com/non_html/Interconnect_stds_MA.pdf
. This new Interconnection Tariff is effective as of May 1, 2013. We strongly encourage all of National Grid’s distributed generation (DG) stakeholders to review this document carefully.
Please refer to the Interconnection Documents
webpage for a list of all relevant Interconnection Process documents.
Please refer to the Net Metering
webpage for more information about billing options related to DG interconnections.
