Service quality guidelines through 2015
Pursuant to G.L. c. 164, section 1E, the DPU established service quality standards in D.T.E. 99-84, later amended in D.T.E. 04-116-C, to ensure that the quality of customer service did not deteriorate with the implementation of a new model of ratemaking, called performance‑based rates. These service quality guidelines were in effect through 2015.
Service quality guidelines as of 2016
Starting in 2016, service quality standards shifted from preventing performance deterioration to requiring improved service quality. The DPU adopted the revised guidelines in D.P.U. 12-120-D. The service quality plans detail how the companies implement the service quality guidelines. The service quality plans are docketed in D.P.U. 16-08 and can be found here:
