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. During the past two years, less polluting No. 4 oil has replaced the heavier No. 6 oil as the backup fuel in all of our steam and electric generating stations. In the next few years, our generating facilities will be further transitioning to No. 2 oil, which is lighter and has a lower concentration of criteria pollutants than No. 4 oil, and aligns with New York City’s goal of reducing local air pollution and GHG emissions.
