The ISO New England Electric Generator Air Emissions Reports available below provide a comprehensive analysis of New England electric power generator air emissions (nitrogen oxides [NOX], sulfur dioxide [SO2], and carbon dioxide [CO2]) and a review of relevant system conditions.
During the 10-year period from 2009 through 2018, total system emissions have decreased overall: NOX by 43%, SO2 by 94%, and CO2 by 31%. The decline in emissions during this period reflects shifts in the regional generation mix, with increasing natural-gas-fired generation as well as wind generation offsetting decreases in coal- and oil-fired generation.
Part of the comprehensive planning activities that ISO New England performs include evaluating the environmental impacts of resource and transmission facilities needed to maintain the reliability of New England’s power system. The quarterly environmental reports below track the impact of state and federal environmental requirements on the reliability and operation of New England power system and, in turn, the environmental consequences of its operations.
