Planning for future uncertainties in electric power generation: an analysis of transitional strategies for reduction of carbon and sulfur emissions

The authors discuss strategies for the US electric utility industry for reduction of both acid rain producing and global warming gases. The EPRI electric generation expansion analysis system (EGEAS) utility optimization/simulation modeling structure and the EPRI developed regional utilities were used. The focus is on the northeast and east central regions of the US. Strategies identified are fuel switching (predominantly between coal and natural gas), mandated emission limits, and a carbon tax. The overall conclusions are that conservation will always benefit carbon emissions but may not reduce acid rain emissions by the offsetting 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.<
