We are also converting the generating equipment at our steam and electric generating stations to burn No. 4 oil as the backup fuel to natural gas instead of No. 6 oil, which is heavier and contains a higher concentration of criteria pollutants. All Con Edison units will be converted by the end of 2019, in order to be capable of burning No. 4 fuel oil by the winter of 2019-20 and to meet the City of New York’s new requirements. With our system already burning more than 90 percent natural gas, this step further reduces the total emissions of the steam system that followed the significant gas emissions additions conversions completed in 2013.
