What information is contained in eGRID?
For every power plant and electric generating company in the United States, eGRID provides: • A detailed emissions profile, covering nitrogen oxides (NOX), sulfur dioxide (SO2), carbon dioxide (CO2), mercury (Hg), and new this year, methane (CH4) and nitrous oxide (N2O). Emissions are reported in tons (pounds for Hg, CH4 and N2O), output emission rates in lb/MWh (pounds per gigawatt-hour for Hg, CH4 and N2O), and input-based emission rates in pounds per million British thermal units (lb/MMBtu) (pounds per billion Btu for Hg, CH4 and N2O), • Generation resource mix, in megawatt-hours and percent, and • Identification, ownership, corporate affiliation, and locational information. eGRID also provides separate data files at the boiler and generator level. Emissions and resource mix data from the plant level are aggregated by electric generating company, parent company, state, U.S. total, and three types of power grid regions: • NERC region, as designated by the North American Electric Reli
