May 28, 2021


Under regulations adopted by the D.C. Public Service Commission, all electricity suppliers and electricity companies operating in the District of Columbia must report to the Commission every six months the fuel mix of electricity sold and the emissions produced. The fuel mix report must be in a format similar to the information provided by the PJM Environmental Information Services (PJM EIS). Every 2 years, the Commission will report to the D.C. Council on the overall fuel mix of electricity sold in the District, and the feasibility of the electric supplies in the District to provide a minimum percentage of electricity sold from renewable energy sources as provided in the District's Renewable Portfolio Standard. 

Electricity suppliers and electricity companies must also provide a fuel mix report to customers twice annually, within the June and December billing cycles. Emissions information must be disclosed every six months on a pound per megawatt-hour (MWh) basis.
