Description (excerpt):
New environmental regulations, technological advances, and market trends are transforming the methods, locations, and characteristics of the resources used to generate and deliver electricity. The promulgation of the United States Environmental Protection Agency (EPA) Clean Power Plan (CPP) sends clear policy signals across the nation that tomorrow’s electricity should be generated with fewer carbon dioxide (CO2) emissions. Those signals are reinforced by the on-going review of the Regional Greenhouse Gas Initiative (RGGI), which is considering additional reductions in CO2 emissions from the power industry in the Northeast. Beyond efforts to reduce CO2 emissions, EPA has also proposed further reductions in emissions of ozone precursors emitted from power plants in New York and the surrounding region through its proposed Cross-State Air Pollution Rule (CSAPR) Update Rule and associated ozone season NOx limits.
Based on the above-referenced environmental initiatives, among others, the composition and operation of the New York Control Area (NYCA) fleet will need to adjust to comply with these new requirements, while continuing to meet reliability criteria at a reasonable cost. This Study is designed to provide the New York State Department of Environmental Conservation (DEC), other policymakers, market participants, and interested stakeholders important information about the ability of the NYCA to achieve compliance with these new regulations, information about changes in emission patterns, and the impacts on costs.
This Study has been designed in two stages—first, to build upon existing work at the NYISO, and then to perform additional work over a longer planning horizon. This Study has looked at various CO2 caps and changes in the resource mix. Further work will examine system intra-hour operational performance, resource adequacy, transmission security, and system stability under various operating conditions.
