Fuel Mix and Emissions Disclosure

August 09, 2023


Massachusetts' 1997 electric utility restructuring legislation authorized the Massachusetts Department of Telecommunications and Energy (DTE)* to require certain electricity providers to disclose details on their fuel mix and emissions to end-use customers. In February 1998, the DTE issued final rules requiring competitive suppliers and distribution companies providing standard offer generation service or default generation service to provide this information to customers quarterly and upon request.

* In 2007, the Massachusetts Department of Telecommunications and Energy (DTE) was dissolved. In its place, the Massachusetts Department of Public Utilities (DPU) was organized to handle electric, gas, siting, pipeline, water, and transportation issues.
