Carbon-Free Electricity Supply

Help meet your environmental and climate change goals by supporting the production of electric power from generation sources that do not directly emit greenhouse gases (GHG).

By purchasing carbon-free electricity from Constellation, your business will realize the value associated with emissions-free generation.

Emission-Free Energy Certificates (EFECs) are created to represent the emission-free attributes of generating sources, as defined by PJM, that do not directly emit greenhouse gases from combustion. When you purchase a Carbon-Free Electricity Plan from Constellation, electricity you purchase will be matched with EFECs from those energy sources providing you with carbon-free electricity. Constellation’s Carbon-Free Electricity product is primarily source from nuclear facilities located within the PJM service territory, although Constellation reserves the right to supply EFECs from any generating facility that does not directly emit greenhouse gases, including hydropower, solar, or wind.
