Fuel Mix and Emissions Disclosure

August 10, 2023


Maryland’s 1999 electric utility restructuring legislation requires all electric companies and electricity suppliers to provide customers with details regarding the fuel mix and emissions of electric generation. Emissions data must be expressed in terms of pounds per megawatt-hour (MWh). This information must be provided to customers every six months and annually to the Maryland Public Service Commission (PSC). Past reports are available in Case No. 8738 through the PSC's Case File Search web page. Current supplier reports are also posted on company web sites.
