Planning for Future Uncertainties in Electric Power Generation: an Analysis of Transitional Stragegies for Reduction of Carbon and Sulfur Emissions

The objective of this paper is to identify strategies for the U S electric utility industry for reduction of both acid rain producing and global warming gasses The research used the EPRI Electric Generation Expansion Analysis System (EGEAS) utility optimization / simulation modeling structure and the EPRI developed regional utilities It focuses on the North East and East Central region of the U S Strategies identified were fuel switching -predominantly between coal and natural gas. mandated emission limits and a carbon tax The overall conclusions of the study are that using less (conservation) will always benefit Carbon Emissions but may or may not benefit Acid Rain emissions by the off setting forces of improved performance of new plant as opposed to reduced overall consumption of final product Results of the study are highly utility and regional demand specific The study showed, however that significant reductions in both acid rain and global warming gas production could be achieved with relatively small increases in the overall cost of production of electricity and that the current dispatch logics available to the utility control rooms were adequate to reschedule dispatch to meet these oblectives
