Air Quality/Non-GHG Emissions
We predominantly use natural gas for energy production. However, to maintain reliability during periods of gas-system limitations, we retain a backup fuel source. While we had been using No. 6 oil as a backup fuel, two of our steam and electric generating stations have now been converted to be able to burn No. 4 oil instead. This oil is lighter and has a lower concentration of criteria pollutants. All Con Edison units will be converted to have the capability to burn a lighter oil as currently required by law, and in keeping with New York City’s goal of reducing GHG emissions.
