Annual service quality reports

Here, you can find out how the Department of Public Utilities (DPU) regulates service quality standards.

The electric companies file their service quality annual reports (SQAR) in compliance with D.P.U. 12-120-D every year on March 1^st.  The SQARs detail the companies’ performance for the filing year by reporting on the required service quality metrics.  The SQARs case numbers are as follows:

Case number	Company Name
XX-SQ-10	Unitil
XX-SQ-11	National Grid
XX-SQ-12	National Grid - Nantucket
XX-SQ-13	Eversource Energy
XX-SQ-14	WMECo (prior to 2020)

To access all document filings, please visit the file room and type the case number, replacing the first two digits in a case number with the relevant year’s last two digits.
